Description

  The present invention relates to a photographing apparatus capable of photographing under different photographing conditions.

  Conventionally, there has been a demand to shoot by changing various shooting parameters such as saturation, contrast, white balance, etc. at the time of shooting. After the preliminary shooting and confirming the shooting result, the user sets the shooting parameters. An imaging device that can be corrected has been developed (see, for example, Patent Document 1).

  There is also an imaging device capable of bracket imaging that generates imaging parameters under different imaging conditions for the same subject. According to bracket photography, the effects of various photographing conditions can be compared, and a suitable one can be selected from those photographed images, which is convenient.

At the time of bracket shooting, a shooting parameter setting screen as shown in FIG. 7 is displayed, and the user can select the number of shots and the shift amount of the shooting condition parameters. In the photographing apparatus, the parameter value is automatically shifted by the shift amount selected according to the number of photographs selected by the user, and the parameter value is assigned to each photographing. In the example of FIG. 7, the number of shots is set to “5” and the shift amount is set to “1” for the saturation parameter. In this case, the shooting apparatus shifts the parameter value by 1 for 5 shots, and −2 , -1, 0, +1, +2 parameter values are set.

In the first embodiment, during normal shooting for obtaining one shot image by one shooting, provisional shooting is performed under a plurality of shooting conditions, and a preview image corresponding to each shooting condition is obtained from the shot images obtained by the temporary shooting. Is generated and displayed on the sub-screen. When the user selects a desired shooting condition from the preview images and the shooting is instructed, an example of shifting to the main shooting under the shooting condition will be described. .

  In the following description, bracket shooting refers to generating a plurality of bracket images with different shooting conditions for the same subject as a shooting target. In bracket shooting, you can shoot multiple times continuously while changing the shooting conditions and generate multiple bracket images for each shooting, and you can shoot only once, and the shooting image obtained by this shooting can be used as shooting conditions. And a method of generating a plurality of bracket images by performing corresponding image processing. The former is applied in the case of a photographing condition that needs to be changed during photographing such as an aperture or a shutter speed, and the latter is applied in the case of a photographing condition that requires image processing such as saturation and contrast. A bracket image refers to a plurality of captured images generated by bracket shooting, and these are captured or image-processed according to parameters of different shooting conditions set for each bracket image.

First, the configuration will be described.
FIG. 1 shows an internal configuration of the photographing apparatus 1 in the first embodiment.
As the photographing device 1, an information processing device such as a digital camera, a digital video camera, a mobile phone having a camera function, a portable terminal such as a PDA (Personal Digital Assistant), a personal computer equipped with a camera, or the like can be applied.

  As shown in FIG. 1, the photographing apparatus 1 includes a CPU (Central Processing Unit) 11, a display unit 12, an input unit 13, a camera unit 14, a RAM (Random Access Memory) 15, a storage unit 16, and an image processing unit 17. Each part is connected via a bus 18.

  The CPU 11 reads various control programs such as the normal photographing processing program (see FIG. 3) according to the present invention from the storage unit 16, performs various calculations and determinations according to the program, and comprehensively controls the execution of the processing. The contents of the process will be described later.

  The display unit 12 is a display unit configured to include a display such as an LCD (Liquid Crystal Display), and a setting screen for setting a menu screen and shooting conditions at the time of shooting on the display according to display control of the CPU 11. Various operation screens such as the above, and a captured image generated by photographing are displayed.

  The input unit 13 includes a shutter button for instructing shooting, a cursor key for performing a selection operation, a determination key for performing a confirming operation, a mode switching key for switching operation modes such as a shooting mode and a playback mode, The input means is configured to include various operation buttons such as a preview button as an instruction means for preview display. The input unit 13 generates an operation signal corresponding to the operated button and outputs the operation signal to the CPU 11.

  The camera unit 14 performs imaging according to control by the CPU 11 and generates data of the captured image. The camera unit 14 includes, for example, a photographing lens, a diaphragm mechanism, an image sensor, a drive circuit, an analog processing circuit, an A / D conversion circuit, a buffer register, a signal processing circuit, and the like.

A photographing method using the camera unit 14 will be described.
First, when a subject image (an optical image of a subject) enters the camera unit 14, the subject image is formed on an imaging element such as a CCD (Charge Coupled Device) via a photographing lens and a diaphragm mechanism. In the imaging device, a subject image is formed, and charges corresponding to the amount of light are accumulated. The accumulated charges are sequentially read out by a drive pulse signal provided from the drive circuit and output to the analog processing circuit. . The analog processing circuit performs various signal processing such as color separation, gain adjustment, and white balance, and the processed signal is stored in a buffer register as a digital data frame image (still image) via the A / D conversion circuit. Is done. Next, the frame image stored in the buffer register is converted into a luminance signal and a color difference signal in the signal processing circuit, and is output to the RAM 15 shown in FIG.

  The RAM 15 is a work memory that provides a temporary storage area to the CPU 11.

The storage unit 16 stores various control programs and various data such as parameters necessary for processing and processing results.
The storage unit 16 stores files including a bracket setting file 161, a normal shooting setting file 162, a shift definition file 163, and an image file 164.

The bracket setting file 161 is a file in which setting information of parameter values for each shooting condition in bracket shooting is stored.
As shown in FIG. 2, the bracket setting file 161 stores parameter values set for each shooting condition of saturation, contrast, sharpness (sharpness), filter, and color enhancement for each shooting order in bracket shooting. ing. For example, in the case of shooting order 1, the parameter values of saturation “−2”, contrast “−2”, sharpness “−2”, filter, and color enhancement “OFF (not set)” are set.

  The normal shooting setting file 162 is for managing setting information of shooting conditions when performing normal shooting, not bracket shooting. That is, the normal shooting setting file 162 has the same file structure as that obtained by deleting the shooting order item in the bracket setting file 161 shown in FIG. 2, and stores only shooting conditions for one shooting. Become.

  The shift definition file 163 is a file in which the shift amount in the case of automatically setting the shift amount of the shooting parameter at the time of bracket shooting on the shooting device 1 side is defined. For example, when the saturation parameter is defined as a shift amount “1” within the range of “−2 to 2”, “−2”, “−1”, “0”, “+1” for each shooting. ”,“ +2 ”and parameter values are allocated.

The image file 163 is a file for managing captured image data generated by the camera unit 14.
A portable external memory may be connectable, and the image file 163 may be stored in the external memory.

  The image processing unit 17 performs various image processes on the captured image in accordance with instructions from the CPU 11. Examples of the image processing include gradation conversion processing, sharpness adjustment processing, and color conversion processing.

Next, the operation of the photographing apparatus 1 will be described.
FIG. 3 is a flowchart for explaining the normal photographing process executed by the photographing apparatus 1 in the normal photographing mode.
In the normal shooting process shown in FIG. 3, first, the CPU 11 determines whether or not the display of the shooting condition setting menu is instructed via the input unit 13 (step A1). (Step A1; N), the process proceeds to the display processing of the instructed menu. On the other hand, when the shooting condition setting menu is displayed (step A1; Y), the process proceeds to step A2. Here, a description will be given on the assumption that a menu display for setting saturation as an imaging condition is instructed.

  When the display of the shooting condition setting menu is instructed, provisional shooting is performed in the camera unit 14 under the control of the CPU 11 (step A2). The provisional photographing may be performed at the timing when the user presses the shutter button, or may be automatically performed in the photographing apparatus 1 after a predetermined time from the menu display instruction. When data of a captured image is generated by the camera unit 14 by provisional shooting, the captured image is temporarily stored in the RAM 15 (step A3).

  Next, the shift definition file 162 is read by the CPU 11, and each parameter value obtained by shifting the saturation parameter value by a predetermined amount according to the shift definition file 162 is obtained. Then, the photographed image is read from the RAM 15, and the image processing unit 17 performs color conversion processing and reduction processing according to each saturation parameter value on the photographed image. A preview image) is generated (step A4).

  Note that in this embodiment, the example of the shooting condition of saturation related to image processing is described, and therefore, a captured image obtained by one shooting is subjected to image processing to cope with a plurality of different saturation parameters. A preview image to be generated is generated. However, in the case of shooting conditions that need to be changed during shooting, such as the aperture and shutter speed, first, the shift definition file 163 is read, a plurality of parameter values are set, and these parameter values are continuously changed a plurality of times. Then, photographing is performed to obtain a photographed image corresponding to each parameter value, and a preview image obtained by reducing the photographed image is obtained.

  Next, the through image is displayed on the entire display screen of the display unit 13 by the display control of the CPU 11. A through image refers to an image that is displayed without saving a frame image generated by the camera unit 14. Then, by the display control of the CPU 11, a small screen is provided on the through image, and the generated preview image is displayed as shooting condition selection information on the small screen (step A5).

FIG. 4 shows a display example of the preview image.
For example, when the saturation parameter values are assigned to “−2”, “−1”, “0”, “+1”, and “+2”, a preview image-processed with each parameter value as shown in FIG. Images x11 to x15 are displayed on the small screen. Below the preview images x11 to x15, information P of the parameter value of the saturation is displayed in association with each other.

  Further, these preview images x11 to x15 also have a function as selection information for selecting a shooting condition at the time of actual shooting. That is, when the user moves the cursor to desired preview images x11 to x15, the saturation parameter of the preview image can be selected as a shooting condition at the time of actual shooting. Then, the subject is confirmed by the through image, and when performing the main photographing, the shutter button is pressed in that state.

  In the photographing apparatus 1, when the cursor key is operated through the input unit 13 in a state where the preview image is displayed in step A5 in FIG. 3 (step A6; Y), the display of the CPU 11 is displayed according to the operation amount. Under the control, the cursor is moved and displayed on the preview image (step A7). When the shutter button is pressed through the input unit 13 (Step A8; Y), the camera unit 14 performs actual shooting (Step A9) and the saturation parameter corresponding to the selected preview image. The value is stored in the normal shooting setting file 162 (step A10).

  Next, when the photographed image generated by the main photographing is temporarily stored in the RAM 14 (step A11), the color conversion process according to the saturation parameter value stored in the normal photographing setting file 162 by the image processing unit 17 is performed. It is applied to the captured image. The captured image after image processing is displayed on the display unit 12 for confirmation (step A12).

  Note that, as in the case of provisional shooting, this embodiment has been described with an example of the shooting conditions for saturation related to image processing, so the saturation parameter value corresponding to the preview image selected after shooting is performed. The selected parameter value is reflected in the captured image by performing image processing according to the above. However, for shooting conditions that need to be changed during shooting, such as aperture and shutter speed, shooting is performed with the parameter value corresponding to the selected preview image, and the parameter value selected by the preview image is reflected during shooting. Is done. That is, the processing is slightly different from the case of the shooting conditions related to image processing.

  When the captured image is displayed for confirmation, a message “Do you want to save?” Is displayed on the display unit 12 by the display control of the CPU 11 (step A13). As a result of confirming the image quality and the like of the displayed captured image, the user performs a save instruction operation if the captured image is satisfactory, and performs a re-shoot instruction operation if the captured image is not satisfactory.

  In the photographing apparatus 1, when the user performs an instruction to retake the image instead of saving the photographed image (step A 14; N), the process returns to step A 4, and the preview image is re-displayed according to other saturation parameter values. The main shooting is repeated. On the other hand, when an instruction is made to save the captured image (step A14; Y), the captured image temporarily stored in the RAM 15 is stored in the image file 164 of the storage unit 16 under the control of the CPU 11 (step A15). When the message “The captured image has been saved” is displayed on the display unit 12 (step A16), the present process is terminated.

  As described above, according to the first embodiment, provisional photographing is first performed when setting photographing conditions, and a plurality of preview images reflecting different photographing conditions are generated based on the obtained photographed images. These preview images are displayed as selection candidates for each shooting condition, and the main shooting is performed under the shooting conditions selected by the preview image. Therefore, before the main shooting, the user can perform shooting effects under different shooting conditions depending on the preview image. After confirming the above, it is possible to select the shooting conditions for the actual shooting.

  Also, since the preview image is a reduced image, the time until display can be shortened. In addition, a through image is displayed in the background of the preview image, and when the shutter button is pressed with the preview image selected, the actual shooting is performed as it is. Can move. Conventionally, after setting the shooting conditions, it has been complicated to set the shooting mode once and then move to shooting, but according to the present invention, immediately after selecting the shooting conditions, Photography can be performed, and operability is good and photographing efficiency is good.

In addition, the imaging device 1 in this embodiment is a suitable example to which the present invention is applied, and is not limited to this.
For example, the preview image is generated using a captured image obtained by provisional shooting, but a sample image is prepared in advance without actually shooting and is displayed as a preview image. Also good.

  In addition, when the shooting condition is selected based on the preview image, a marker may be displayed as identification information indicating that the main shooting is performed based on the shooting condition of the selected preview image. In this case, the user can easily grasp the shooting conditions for performing the main shooting.

  In addition, the through image is displayed on the entire screen and the preview image is displayed on the child screen thereon. However, the display of the full screen and the child screen may be switched according to the user's operation. That is, when the switching display is instructed by the user, a plurality of preview images displayed on the sub-screen are sequentially switched and displayed on the entire screen. Alternatively, the preview image displayed on the child screen may be enlarged and displayed according to the instruction operation. As a result, the preview image can be enlarged and displayed, and the shooting effect can be easily confirmed.

  In addition, the preview image is displayed on a small screen, but if the screen size of the display unit 12 is small, the review image is also small. In this case, since it may be difficult to confirm the shooting effect, the image processing unit 17 may perform image processing that emphasizes the shooting effect on the preview image. For example, when shooting splashes, if the shutter speed is set fast to capture an image that captures water droplets, sharpness adjustment is emphasized by sharpness adjustment processing, and the flow of water is expressed. Therefore, if the shutter speed is set slower, the sharpness is lowered. Thereby, since the shooting effect is emphasized, the shooting effect can be grasped even if the display size of the preview image is small.

  In the above example, only the shooting conditions for saturation have been set. However, the present invention is not limited to this, and each shooting condition such as aperture, shutter speed, white balance, contrast, color filter, and sharpness (sharpness) is also described. May be set in combination, and a preview image reflecting the set shooting conditions may be displayed. Thereby, it is possible to easily confirm the shooting effect under other shooting conditions.

Second Embodiment
In the second embodiment, when bracket shooting is performed, provisional shooting is performed to generate preview images based on a plurality of shooting conditions, which are displayed as selection candidates for each shooting condition, and only based on the shooting conditions selected by the preview image. An example of performing actual photographing will be described.

First, the configuration will be described.
Since the basic configuration of the imaging device in the second embodiment is the same as that of the imaging device 1 (see FIG. 1) shown in the first embodiment, the same components are the same as the imaging device 1 of the first embodiment. A reference numeral is attached and the illustration is omitted, and only different functional parts will be described. That is, the photographing apparatus 1 according to the second embodiment includes a CPU 11, a display unit 12, an input unit 13, a camera unit 14, a RAM 15, a storage unit 16, and an image processing unit 17.

  The CPU 11 reads out a bracket shooting processing program (see FIG. 5) unique to the second embodiment from the storage unit 16, and comprehensively controls the execution of the processing.

Next, the operation will be described.
FIG. 5 is a flowchart for explaining the bracket photographing process executed by the photographing apparatus 1 in the bracket photographing mode.
In the bracket shooting process shown in FIG. 5, a bracket menu screen for setting shooting conditions for bracket shooting is first displayed on the display unit 12 (step B1). On the bracket menu screen, an input area for the parameter shift amount and the number of times of photographing for each photographing condition is displayed, so that the user inputs a desired parameter shift amount and the number of times of photographing.

  In the photographing apparatus 1, the parameter value of each photographing condition is shifted and assigned to each photographing in accordance with the parameter shift amount and the number of photographing input through the input unit 13, and the setting value is assigned to the bracket setting file 161. (Step B2). When the setting is completed, image capture is started by the camera unit 14, and the through image is displayed on the display unit 12 (step B2).

  When the preview button is pressed by the user in this state (step B4; Y), the bracket setting file 161 is read by the CPU 11, and provisional shooting (hereinafter referred to as bracket shooting) is performed based on the parameter value stored in the file. , Referred to as bracket temporary shooting) (step B5). In the bracket temporary shooting, if a set shooting condition includes a condition related to shooting (for example, an exposure condition), shooting is performed a plurality of times according to the shooting condition. , Saturation, contrast, etc.), that is, in the case of only shooting conditions corresponding to image processing, shooting is performed only once. In this case, the captured image is subjected to image processing corresponding to the shooting conditions, and a bracket image corresponding to each shooting condition is obtained.

  The photographed image obtained by the provisional photographing is temporarily stored in the RAM 15 (Step B6). Next, based on the parameter values stored in the bracket setting file 161, the image processing unit 17 performs necessary image processing on the captured image, and performs reduction processing to generate a preview image. Necessary image processing is processing according to the shooting conditions related to image quality as described above, such as color conversion processing. Then, by the display control of the CPU 11, a plurality of small screens are provided on the through screen, and the generated preview image is displayed on the small screen (step B7).

FIG. 6 shows a display example of the preview image.
As shown in FIG. 6, a through image X2 is displayed on the entire display screen, and a plurality of preview images x21 to x25 obtained by bracket shooting are displayed on a plurality of small screens. Below the preview images x12 to x25, information P indicating the shooting conditions is displayed in association with each preview image.

  Further, these preview images x21 to x25 also have a function as selection information for selecting a shooting condition at the time of actual shooting. That is, the user can select a shooting condition at the time of actual shooting by moving the cursor to a desired preview image. One or a plurality of preview images can be selected. Then, the subject is confirmed by the through image, and when the main photographing is performed, the shutter button is pressed in that state.

  In the photographing apparatus 1, when a preview image is selected with the cursor via the input unit 13 (step B8; Y), as shown in FIG. 6, the preview images x21 to 25 selected by the display control of the CPU 11 are displayed. A shooting mark M is displayed as identification information indicating that actual shooting is performed under the shooting conditions (step B9).

  When the shutter button is pressed with the preview image selected (step B10; Y), bracket shooting main shooting (hereinafter referred to as bracket main shooting) is performed only based on the shooting conditions of the selected preview image. (Step B10). In the case of this bracketing main shooting, as in the case of provisional shooting, the shooting and image generation processes differ depending on whether the shooting conditions include conditions related to shooting or only conditions related to image processing, as described above. is there.

  The photographed image generated by the bracket main photographing is temporarily stored in the RAM 15 (step B12). Next, after the image processing unit 17 performs necessary image processing on the captured image in accordance with each parameter stored in the bracket setting file 161, the captured image after the image processing is displayed on the display unit 12 for confirmation. (Step B12). Next, under the display control of the CPU 11, a message “Do you want to save the captured image?” Is displayed on the display unit 13 (step B 13), and when saving is instructed (step B 14; Y), it is stored in the RAM 15. The captured image is stored in the image file 164 of the storage unit 16, and a saving process is performed (step B15). Then, when the message “The captured image has been saved” is displayed on the display unit 12 (step B16), the present process is terminated.

  On the other hand, if saving of the photographed image is not instructed (step B14; N), the photographed image in the RAM 15 is not saved in the image file 164, and the message “Image has been deleted” is displayed on the display unit 12. (Step B17), and this process is terminated. That is, the captured image is stored in the RAM 15 in a state where it can be overwritten.

  As described above, according to the second embodiment, a preview image reflecting a plurality of different shooting conditions is generated by bracket temporary shooting. These preview images are displayed as shooting condition selection candidates at the time of main shooting, and the main shooting is performed under the shooting conditions selected by the preview image. Therefore, before the main shooting, the user has different shooting conditions depending on the preview image. After confirming the shooting effect, the shooting conditions for the actual shooting can be selected. As a result, when performing bracket shooting, only shooting conditions required by the user are shot. Therefore, it is possible to save the trouble of deleting shot images for unnecessary shooting later and improve shooting efficiency.

  In addition, when a through image is displayed on the background of the preview image and the shutter button is pressed while the preview image is selected, the actual shooting of the bracket is performed as it is. Can move on. Conventionally, after setting the shooting conditions, it has been complicated to set the shooting mode once and then move to shooting, but according to the present invention, immediately after selecting the shooting conditions, Photography can be performed, and operability is good and photographing efficiency is good.

  Further, since the selected preview image is displayed with the shooting marker M, the user can easily grasp which preview image has already been selected.

In addition, the imaging device 1 in 2nd Embodiment is a suitable example to which this invention is applied, It is not limited to this.
For example, the through image is displayed on the full screen, and the preview image is displayed on the sub screen. However, the display of the full screen and the sub screen may be switched according to the user's operation. That is, when the switching display is instructed by the user, a plurality of preview images displayed on the sub-screen are sequentially switched and displayed on the entire screen. Alternatively, the preview image displayed on the child screen may be enlarged and displayed according to the instruction operation. As a result, the preview image can be enlarged and displayed, and the shooting effect can be easily confirmed.

  In addition, the preview image is displayed on a small screen, but if the screen size of the display unit 12 is small, the review image is also small. In this case, since it may be difficult to confirm the shooting effect, the image processing unit 17 may perform image processing that emphasizes the shooting effect on the preview image. For example, when shooting splashes, if the shutter speed is set fast to capture an image that captures water droplets, sharpness adjustment is emphasized by sharpness adjustment processing, and the flow of water is expressed. Therefore, if the shutter speed is set slower, the sharpness is lowered. Thereby, since the shooting effect is emphasized, the shooting effect can be grasped even if the display size of the preview image is small.

  In the above example, only the shooting conditions for saturation have been set. However, the present invention is not limited to this, and each shooting condition such as aperture, shutter speed, white balance, contrast, color filter, and sharpness (sharpness) is also described. May be set in combination, and a preview image reflecting the set shooting conditions may be displayed. Thereby, it is possible to easily confirm the shooting effect under other shooting conditions.
