Description

  The present invention relates to a digital camera, a control method for a digital camera, a program, and a storage medium, and in particular, reads image data from a recording medium, transmits the image data to an image printing apparatus together with desired print parameters (paper size, print layout, etc.) and prints the image. The present invention relates to a technique suitable for use in a printing parameter setting method in a printing system.

  When printing with a conventional printing system, first, a printer is connected to the host computer, and application software capable of displaying and processing a document, drawing, image, or the like to be printed is started on the host computer. Then, data to be printed is read, print parameters are set, the data is transmitted to the printer, and printing is performed. At this time, the user can freely specify various print parameters (for example, print quality paper size, number of copies, print range, print layout, etc.).

  In such a printing system, the application software displays a preview of the print result, so that the user can set print parameters for obtaining a desired print result. Also disclosed is a printing system in which a host computer acquires print settings on the printer side and performs printing using the settings (see, for example, Patent Document 1).

  In recent years, there is a system in which an image photographing apparatus such as a digital camera is directly connected to a printer without using a host computer, and printing is performed by setting print parameters on the image photographing apparatus. However, in such a printing system, the print result cannot be displayed as a preview, and the user may not be able to determine how to set the print parameters and may not obtain the desired print result. . Therefore, a printing system in which the image capturing apparatus side acquires print settings on the printer side and performs printing using the settings can be easily analogized.

JP 2001-159962 A

  As described above, in the conventional printing system, the user sets the print parameters while considering the settings on the printer side. However, depending on the data to be printed, the print parameters specified in this way may not be optimal. .

  For example, when a low resolution image is printed by specifying a large paper size such as A4 size or A3 size, the print result becomes very rough if the resolution of the original data is low. On the other hand, when a high resolution image is printed with a small paper size such as L size, the advantage of a high resolution image is lost.

  As described above, the print parameters vary depending on the data to be printed, and there is a problem that it is difficult for the user to find an appropriate combination of print parameters.

(First embodiment)
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram illustrating an example of a printing system according to the present embodiment, and includes an image photographing device 100 and an image printing device 120. Specifically, for example, a printing system in which a digital camera and a printer are connected can be considered. The image capturing device 120 includes an image generation device 130 and an image reproduction device 140.

  First, referring to FIG. 1, processing in the image shooting mode will be described. For example, the photographing unit 101 forms a subject image on a CCD surface by a lens optical system, performs photoelectric conversion by the CCD to generate an imaging signal, and further generates digital image signal data by an A / D converter. Have a function of storing in the frame memory.

  When the image signal data is stored in the frame memory, the shooting information generation unit 102 acquires various shooting parameters from the shooting unit 101, encodes the shooting parameters into an appropriate format, and generates shooting information. As the shooting parameters, for example, an image compression ratio, an image width, a height, a shutter speed, a lens parameter, a shooting mode, a white balance, or a focus in-focus position can be considered.

  The image data recording unit 103 records the image signal data sent from the shooting unit 101 and the shooting information sent from the shooting information generating unit 102 in the recording medium 104 in an appropriate file format. For example, as shown in FIG. 2, there is a file format in which shooting information 202 is recorded as a part of the image file 200. The image file 200 includes header data 201 that holds information about the image file itself, the shooting information 202, and image data 203.

  In addition, as shown in FIG. 3, there is a file format in which shooting information 302 is recorded as a shooting information file 301 different from the image file 300. The file name of the image file 300 is recorded as “IMG — 0101.JPG”, and then the shooting information is recorded as the file name “IMG — 0101.PRT” with a different extension, thereby associating the image file 300 with the shooting information file 301. It can be carried out.

  Next, referring to FIG. 1, processing in the image print mode will be described. The image data reading unit 105 reads the image data and shooting information recorded on the recording medium 104, sends the shooting information to the print parameter acquisition unit 106, and sends the image data to the first data communication unit 110 when printing is performed. . Further, the image data can be expanded in the frame memory and previewed on the display 108.

  The print parameter acquisition unit 106 acquires a parameter value suitable as a print parameter from the shooting information and sends it to the print parameter setting unit 107. Hereinafter, the print parameter acquisition unit 106 will be described with reference to the flowchart of FIG.

FIG. 5 is a flowchart illustrating an example of a processing procedure performed by the print parameter acquisition unit 106 according to this embodiment.
The print parameter acquisition unit 106 in FIG. 5 calculates print quality suitable for the selected image from the compression rate of the image data, and acquires it as a print parameter. Further, three types of print parameters that can be used are “draft (low quality)”, “normal (normal)”, and “fine (high quality)”.

  In the case of an irreversible compression method such as JPEG, the higher the image compression rate, the more the quality of the image data deteriorates. Therefore, if the quality of the original image data is low, the print quality parameter may be set to a high quality. The quality of the printed result is unlikely to be high. Therefore, it is first determined whether or not the compression rate is equal to or greater than the threshold value R1 (step S501). If the result of this determination is that the compression rate is equal to or greater than R1, print parameters are set assuming that the print quality is suitable for the draft quality (step S502).

  On the other hand, if the result of determination in step S501 is that the compression rate is smaller than R1, it is determined whether or not the compression rate is greater than or equal to a threshold value R2 (step S503). If the compression rate is equal to or greater than R2 as a result of this determination, the print parameters are set assuming that the print quality is suitable for normal quality (step S504). On the other hand, if the result of determination in step S503 is that the compression ratio is smaller than R2, the print parameters are set assuming that fine quality is suitable for the print quality (step S505).

  The print parameter setting unit 107 displays the print setting screen 400 shown in FIG. 4A on the display 108 and updates the print setting screen 400 by input from the operation switch 109. When the up / down switch of the cross key 402 shown in FIG. 4B is pressed, the cursor 401 moves. Further, when the left and right buttons of the cross key 402 are pressed, the print parameter value of the item on which the cursor 401 is placed changes.

  Taking print quality as an example, the print quality is switched in the order of draft quality 404, normal quality 405, and fine quality 406 as shown in FIG. When the print setting screen 400 is displayed, the print parameter received from the print parameter acquisition unit 106 is set as an initial value.

  When the image selected by the user is changed, similarly, the print parameter suitable for the image is received from the print parameter acquisition unit 106, and the print setting is initialized with the value. In addition, a mark 407 indicating that the value is suitable for the selected image is displayed based on the print parameter value received from the print parameter acquisition unit 106.

  By placing the cursor on “Print” on the print setting screen 400 and pressing the SET switch 403, the image selected with the set print parameters is printed. The image data reading unit 105 transmits image data to the first data communication unit 110, and the print parameter setting unit 107 transmits print parameters to the first data communication unit 110. Then, the first data communication unit 110 encodes the data in an appropriate format, and transmits the encoded data to the image printing apparatus 120.

  The image printing apparatus 120 includes a printing mechanism unit 122, receives print data sent from the outside by the second data communication unit 121, and prints an image. In general, the printing apparatus often includes an interface for connecting to a personal computer. However, in the present embodiment, an interface for connecting to the image capturing apparatus 100 is also provided. Examples of such an interface include a wired connection such as USB (Universal Serial Bus) and a wireless connection such as IEEE 802.11b.

(Second Embodiment)
In the present embodiment, a case where the image printing apparatus 620 has print function information will be described.
FIG. 6 is a block diagram illustrating an example of a printing system according to the present embodiment, and includes an image photographing device 600 and an image printing device 620, as in the first embodiment. Further, the image capturing device 600 includes an image generating device 130 and an image reproducing device 640. In the present embodiment, a print function receiving unit 611 is added to the image capturing apparatus 100 of the first embodiment, and a print function transmitting unit 623 is added to the image printing apparatus 120. In addition, the same number is attached | subjected about the structure same as FIG. 1, and description is abbreviate | omitted about the overlapping structure.

  The printing function transmission unit 623 in the image printing apparatus 620 acquires printing function information supported by the image printing apparatus 620 from the printing mechanism unit 122 and encodes it in an appropriate format. Then, the encoded print function information is transmitted to the image capturing apparatus 600 through the second data communication unit 121.

  The print function receiving unit 611 in the image capturing apparatus 600 receives the print function information supported by the image printing apparatus 620 through the first data communication unit 110 and sends it to the print parameter acquisition unit 106 and the print parameter setting unit 107. .

  An example of the print function information is shown in FIG. The print function information is in the form of a print parameter value list 700 that can be used for each parameter type. At the same time, if there is a print parameter value recommended on the image printing apparatus 620 side, the recommended value information 701 can be transmitted and received.

  A display example of the print setting screen 800 when there is a recommended value on the image printing apparatus 620 side is shown in FIG. In FIG. 8A, the cursor 801 is on the print setting screen 800. When the cursor 801 is selected, a mark 802 indicating the print parameter value sent from the print parameter acquisition unit 106 and a print parameter value recommended on the image printing apparatus 620 side as shown in FIG. A mark 803 indicating the presence is displayed. Further, when it is not included in the usable print parameter value list 700, it is not displayed and the user cannot select it.

  The print parameter acquisition unit 106 acquires a parameter value suitable as a print parameter from the print function information and the shooting information, and transmits the parameter value to the print parameter setting unit 107. Hereinafter, the print parameter acquisition unit 106 will be described with reference to FIG.

FIG. 9 is a flowchart illustrating an example of a processing procedure performed by the print parameter acquisition unit 106 according to the present embodiment.
First, as in the first embodiment, it is determined whether or not the compression rate is equal to or greater than the threshold value R1 (step S901). As a result of the determination, if the compression rate is equal to or greater than R1, it is determined whether the draft quality is suitable and whether the draft quality is usable (step S902).

  If it is determined that the draft quality is usable, the print quality is set to the draft quality and the print parameters are set (step S903). On the other hand, if the compression rate is smaller than R1 as a result of the determination in step S901, or if the draft quality is not usable as a result of the determination in step S902, it is determined whether the compression rate is equal to or greater than the threshold value R2 (step S904). ).

  If the result of this determination is that the compression ratio is equal to or greater than R2, it is determined whether or not normal quality is available (step S905). If the normal quality is usable as a result of this determination, the print quality is set to the normal quality and the print parameters are set (step S906).

  On the other hand, if the compression rate is smaller than R2 as a result of the determination in step S904, or if the normal quality is not usable as a result of the determination in step S905, it is determined that the fine quality is suitable and the fine quality is usable. Is determined (step S907). If the fine quality is usable as a result of this determination, the print quality is set to the fine quality and the print parameters are set (step S908). On the other hand, if the result of determination in step S907 is that the fine quality is not usable, a warning is displayed to the user that there is no usable print quality (step S909), and the process ends.

(Third embodiment)
The print parameter acquisition unit 106 of the second embodiment will be described as another embodiment with reference to the flowchart shown in FIG. Since the functional configuration is the same as that of the second embodiment, description thereof is omitted.

FIG. 10 is a flowchart illustrating an example of a processing procedure performed by the print parameter acquisition unit 106 according to this embodiment.
First, as in the first embodiment, it is determined whether or not the compression rate is equal to or greater than the threshold value R1 (step S1001). If the result of this determination is that the compression rate is equal to or greater than R1, the print parameters are set assuming that the draft quality is suitable for the print quality (step S1002).

  On the other hand, if the result of determination in step S1001 is that the compression rate is smaller than R1, it is determined whether or not the compression rate is greater than or equal to a threshold value R2 (step S1003). If the result of this determination is that the compression rate is R2 or higher, the print parameters are set assuming that the normal quality is appropriate for the print quality (step S1004). On the other hand, if the result of determination in step S1003 is that the compression rate is smaller than R2, print parameters are set assuming that fine quality is suitable for the print quality (step S1005).

  When the print quality is determined by the above processing, it is determined whether or not the selected print quality exists in the print parameter value list 700 and can be used (step S1006). If the result of this determination is that the selected print quality is available, the print quality is left as it is and the process is terminated.

  On the other hand, if the selected print quality is not usable as a result of the determination in step S1006, for example, as shown in FIG. 11A, a warning screen 1100 is displayed to notify the user that a suitable value cannot be used. (Step S1007).

  Thereafter, the print quality is set to a recommended value on the image printing apparatus 620 side (step S1008), and the process ends. Further, the print function information can be obtained again by referring to the print function information by the process shown in FIG.

(Fourth embodiment)
The print parameter acquisition unit 106 of the second embodiment will be described as another embodiment with reference to the flowchart shown in FIG. Since the functional configuration is the same as that of the second embodiment, description thereof is omitted.

FIG. 12 is a flowchart illustrating an example of a processing procedure performed by the print parameter acquisition unit 106 according to this embodiment.
Steps S1201 to S1208 are the same as steps S1001 to S1008 in FIG.

  If the selected print quality is usable as a result of the determination in step S1206, the user selects whether to use the print parameter value determined by the shooting information or the recommended print parameter value on the image printing apparatus 620 side. A message to be displayed is displayed (step S1209). For the message, a message screen 1101 as shown in FIG. 11B is displayed.

  Next, it is determined whether or not to use the recommended printing parameter value on the image printing apparatus 620 side (step S1210). If the result of this determination is that the user has selected to use the recommended print parameter value on the image printing apparatus 620 side, the print quality is set to the recommended value on the image printing apparatus 620 side (step S1211).

  On the other hand, as a result of the determination in step S1210, if the use of the recommended print parameter value on the image printing apparatus 620 side is not selected, the print parameter value determined by the shooting information is set, and the process ends.

(Fifth embodiment)
An embodiment in which the print parameter acquisition unit 106 of the first embodiment determines print parameters for a print range (trimming range) will be described. Since the functional configuration is the same as that of the first embodiment, the description thereof is omitted.

  A display example when designating the printing range is shown in FIG. When the cursor is positioned on the “trimming” item on the print setting screen 1300 shown in FIG. 13A and the SET switch 403 is pressed, a print range designation screen 1301 shown in FIG. 13B is displayed. On the print range designation screen 1301, a print range frame 1302 is displayed, and the position of the print range frame 1302 moves when the cross key 402 is pressed.

  The print parameter acquisition unit 106 acquires the initial setting value of the print range frame 1302 when the print range specification screen 1301 is displayed in a state where the print range is not specified.

  Further, as shown in FIG. 14A, when shooting in the AF (autofocus) mode, the AF frame 1400 set at the subject position is automatically focused. Normally, since the AF frame 1400 is set at the position of the subject, the position of the AF frame is recorded as shooting information. At the time of printing, the print range 1401 can be determined as shown in FIG. 14B assuming that the subject is present at the position of the AF frame 1400.

FIG. 15 is a flowchart illustrating an example of a processing procedure performed by the print parameter acquisition unit 106 when photographing in the AF mode in the present embodiment.
First, it is determined whether the print range 1401 has already been designated (step S1501). If the print range 1401 is designated as a result of this determination, the print range 1401 is set as a print parameter (step S1502).

  On the other hand, if the result of determination in step S1501 is that the print range 1401 is not designated, it is determined whether or not AF frame information is present in the shooting information (step S1503). If the result of this determination is that there is no AF frame information, the print range 1401 is set as a standard value (step S1504). As standard values, the frame position is the center, the frame size is the smallest, and the like.

  On the other hand, if the result of determination in step S1503 is that there is AF frame information, the AF frame information is converted into a print range 1401, the print range 1401 is set according to the position of the AF frame (step S1505), and the process ends. .

  The acquired print range 1401 is transmitted to the print parameter setting unit 107, and a print range frame 1302 is displayed on the print range setting screen 1301. Further, as described above, the user can freely change the print range 1401 on the print range setting screen 1301.
