Description

  The present invention relates to an imaging device for moving images, an imaging device having an imaging device for still images, and a control method thereof.

  There is a demand for recording a specific scene as a still image while shooting a video with a video camera. In response to this demand, a video camera with a still camera has been proposed in which a still camera and a video camera are combined into a single device, and the still camera can be operated without interrupting shooting with the video camera. (For example, refer to Patent Document 1).

  However, in the above proposal, if a flash device such as a strobe or AF auxiliary light is used during still shooting, the moving image shooting screen is affected by the flash device and the image quality is disturbed.

Further, there has been proposed a composite camera that can replace a video signal at the time of flash device emission with a video signal immediately before the flash device emission (see Patent Document 2). However, the frame rate temporarily changes to fit the past video, and the movement becomes awkward. In addition, a new field memory is required to store the video signal immediately before the flash device emits light, leading to an increase in cost.
Japanese Patent No. 2573600 JP 2002-199273 A

  The present invention has been made in view of the above problems, and in an imaging apparatus capable of simultaneously recording a moving image and a still image, the influence on the moving image capturing by the flash for capturing the still image is suppressed, and the stable moving image A technique for realizing image recording is provided.

In order to solve this problem, the imaging apparatus of the present invention has the following configuration. That is,
An imaging apparatus that has a first image sensor for moving images and a second image sensor for still images, and that records moving images and still images,
Flashing means for flashing in the imaging direction for still image imaging by the second imaging element;
Instruction means for instructing still image capturing by the second image sensor;
A flash control unit that controls and drives the flash unit to flash within a predetermined period of the non-accumulation period of the first image sensor when the instruction unit instructs to capture a still image;
And a still image capturing unit that captures a still image by accumulating the second image sensor during a period including a flash period by the flash unit.

  According to the present invention, in a two-plate image pickup apparatus capable of simultaneously recording a moving image and a still image, flash means such as a strobe for still image shooting and an AF auxiliary light within the non-accumulation period of the image pickup device for moving image shooting By performing flashing (light emission) according to the above, it is possible to suppress the influence of flashing on the recorded moving image and to realize stable moving image recording.

  Hereinafter, embodiments according to the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is a schematic configuration diagram illustrating a configuration of an imaging apparatus according to the embodiment.

  In the figure, reference numeral 101 denotes a lens, and a diaphragm 102 is disposed behind the lens 101. The light passing through the lens 101 and the diaphragm 102 is separated in two directions by the half mirror 103 and formed as subject images on the imaging surfaces of the movie (moving image) CCD 105 and the still (still image) CCD 107, respectively. . At this time, a shutter 104 is provided on the front surface of the Still CCD 107 so that extra charges are not accumulated during a signal readout period from the Still CCD 107. In the movie CCD 105 and the still CCD 107, the formed subject image is converted from an optical signal to a video signal.

  Note that the number of imaging pixels of the still (still image) CCD 107 is of the millions of pixels class in order to improve the image quality and resolution as a still image, similar to that of recent digital cameras. That is, the number is sufficiently larger than the number of pixels of the movie (moving image) CCD 105.

  The video signal obtained by the movie CCD 105 is sent to the movie signal processing unit 112. The video signal is subjected to predetermined processing in the movie signal processing unit 112, recorded on a removable magnetic tape 115, and / or output to the display 116. Although a magnetic tape is taken as an example of a medium for recording a moving image here, it goes without saying that a rotating storage medium such as a disk may be used.

  The image signal obtained by the Still CCD 107 is sent to the Still signal processor 114. The still image signal processing unit 114 performs predetermined processing (correction and compression encoding) on the image signal, and the image signal is recorded on the removable memory card 118.

  A camera microcomputer 111 controls the entire apparatus. Through the movie CCD drive control unit 106 and the still CCD drive control unit 108, control such as accumulation and reading of the movie CCD 105 and the still CCD 107 is performed. Further, the flash drive control unit 110 controls the light emission amount, the light emission timing, and the like of the strobe device 109 that is an auxiliary unit for taking a still image. When still image shooting is performed using the strobe device 109 during moving image shooting, the camera microcomputer 111 sends commands to the Still CCD drive control unit 108 and the strobe drive control unit 110, and the accumulation period of the Still CCD 107 and the strobe device 109. Controls the light emission timing and performs still image shooting.

  Control of the Movie CCD 105, the Still CCD 107, and the strobe device 109 by the camera microcomputer 111 will be described in detail later.

  FIG. 2 is a perspective view illustrating an overview of the imaging apparatus according to the embodiment.

  In the figure, reference numeral 120 denotes an image pickup apparatus main body. A recording medium such as a magnetic tape 115 and a memory card 118 is accommodated in the imaging apparatus main body 120 so that a video signal and a still image can be recorded and reproduced. Reference numeral 121 denotes a lens unit. Reference numeral 122 denotes a microphone, which is provided for recording sound during shooting. Reference numeral 123 denotes an electronic viewfinder (EVF), which is provided for aiming and checking a subject when taking a picture by looking into the camera.

  Reference numeral 124 denotes a moving image trigger switch. The moving image trigger switch 124 is a push button, and is a switch operated by the user to transmit the start and end of moving image shooting to the device. When the switch 124 is pressed, the recording state (recording state on the magnetic tape 115) is entered, and when the switch 124 is pressed again, the recording ends (non-recording state).

  Reference numeral 125 denotes a still image trigger switch. The still image trigger switch 125 is a push button, and is a switch operated by the user to transmit the start and end of still image shooting to the device. When this switch is pressed once, the shutter 104 is opened for the exposure time determined based on the exposure amount at that time, the charge is accumulated in the still CCD 107, and it is taken out as a still image signal, and predetermined image processing and compression are performed. The data is encoded and stored in the memory card 118.

  Reference numeral 131 corresponds to the strobe device 109, and emits light as necessary as an auxiliary means for photographing a still image.

  A mode dial 126 is composed of a rotary switch. The mode dial 126 can select, for example, “playback” set to the playback mode, “camera” set to the camera mode, and “power off” which is none of them.

  Reference numeral 127 denotes a group of operation switches, on which keys for a reproduction system and menu operation are arranged for the user to operate the main body.

  Reference numeral 128 denotes a liquid crystal panel attached to the side of the main body so as to be freely opened and closed. Like the EVF 123, the liquid crystal panel 128 is mainly used for confirming a subject image during camera shooting and for displaying a reproduced image during reproduction. The liquid crystal panel 128 can be rotated in the horizontal direction while being opened from the main body 120. A display 116 in FIG. 1 corresponds to a liquid crystal panel 128 and an electronic viewfinder (EVF) 123.

  Reference numeral 129 denotes a speaker, which is provided for outputting sound when reproducing. A battery 130 is detachable from the main body 120.

  Next, still image shooting processing in the imaging apparatus of the present embodiment will be described with reference to the schematic configuration diagram of FIG. 1, the apparatus perspective view of FIG. 2, and the flowchart of FIG. It should be noted that the camera microcomputer 111 performs AF and AE by controlling the lens 101 and the diaphragm 102 according to a known technique. This is because the accumulation period is set for the movie CCD drive unit 106. However, please note that there are some points. In addition, in order to simplify the description, it is assumed that the moving image in the embodiment is captured in the NTSC system, and 60 fields are captured per second.

  When the still image trigger switch 125 is pressed by the user, a still image shooting request is made (step S102). Here, the camera microcomputer 111 determines whether or not moving image shooting / recording is in progress (moving image is being recorded on the magnetic tape 115) (step S103). A control signal is sent to 108 and the still CCD 107 is controlled to take a still image as usual (step S108). At this time, it does not matter whether or not the flash device 109 is flashed.

  Incidentally, as a condition for flashing, when the operation switch group 127 is operated and the user instructs intentional flashing, the operation switch group 127 is operated to set the automatic strobe mode, and the camera There are two cases when the microcomputer 111 determines to flash based on the exposure amount or the like.

  On the other hand, if it is determined that the still image trigger switch 125 has been pressed during moving image recording, the camera microcomputer 111 determines whether to use (flash) the strobe device 109 for still image shooting (step S104). . When the strobe device 109 is not used, the camera microcomputer 111 sends a command to the Still CCD drive control unit 108 to control the Still CCD 107 and to perform still image shooting as usual (step S108).

  When it is determined that the strobe device 109 is used, the camera microcomputer 111 determines whether the movie CCD 105 is within a predetermined period (details will be described later) within the non-accumulation period. If not, it waits until it falls within the predetermined period.

  Thus, when it is determined that the movie CCD 105 is in a predetermined period within the non-accumulation period, the camera microcomputer 111 outputs a drive control signal to the flash drive control unit 110 in order to flash the flash device 109 (step S106) and the shutter. 104 is set to open time and disclosed to the still CCD 107 for storage, and still image shooting is performed (step S107). As a result, an image signal obtained by imaging with the Still CCD 107 is subjected to predetermined processing and compression coding by the Still signal processing unit 114 and stored in the memory card 118.

  The moving image shooting process is based on a well-known technique and will not be described. Hereinafter, the accumulation period of the movie CCD 105 and the still CCD 107 and the flash period of the strobe device 109 during still image shooting will be described with reference to the schematic timing diagram of FIG.

  FIG. 3A shows an example in which the still image trigger switch 104 is pressed during the accumulation period of the movie CCD 105 during shooting and recording by the movie CCD 105. The Ts shown is the timing when the still image trigger switch 104 is pressed.

  Here, in the embodiment, an example is described in which a moving image is captured at 60 fields / second by NTSC. Therefore, the total period of the accumulation period Tc and the readout period (non-accumulation period) Tr by the movie CCD 105 is 1/60. Second.

  When the strobe device 109 is not flashed, moving image shooting and still image shooting do not interfere with each other. Therefore, at the timing Ts when the still image trigger switch 104 is pressed, accumulation of the still CCD 107 is started. It doesn't matter. The storage period of the still CCD 107 at this time is a time based on the exposure amount when the still image trigger switch 104 is pressed. When the accumulation period ends, a signal is read out from the still CCD 107, a predetermined process (including an image compression encoding process) is performed by the still image signal processing unit 114, and stored in the memory card 118.

  On the other hand, FIG. 3B shows the timing when the flash device 109 is flashed.

  For comparison, FIG. 3B shows an example in which the still image trigger switch 104 is pressed in the same situation as FIG.

  The timing Ts when the still image trigger switch 104 is pressed is an accumulation period by the movie CCD 105. Therefore, after the accumulation period of the movie CCD 105 ends (or when the video signal is read from the movie CCD 105), the accumulation of the flash of the strobe device 109 and the still CCD 107 is started. The subsequent processing is the same as the still image shooting processing in FIG.

  Next, the case where the timing Ts when the still image trigger switch 104 is pressed is in the signal readout period from the movie CCD 105 will be described with reference to FIG.

  In this case, the accumulation of the flash of the strobe device 109 and the still CCD 107 may be basically started at the timing Ts when the still image trigger switch 104 is pressed. However, since it is necessary to consider the flash (light emission) time ΔT (generally about 1/8000 second) by the strobe device 109, the following condition must be satisfied.

  That is, when the timing before the next field accumulation start timing T2 by the flash period ΔT is defined as T3, the still image trigger switch 104 is pressed within the period Tf (= period from T1 to T3). If there is a timing Ts, accumulation of the flash of the strobe device 109 and the still CCD 107 is started at the timing Ts. Otherwise, it waits until the timing T4 when the accumulation of the next field is completed.

  As described above, in any of FIGS. 3B and 3C, if the timing Ts when the still image trigger switch 104 is pressed is within the period Tf, the strobe device 109 is operated at the timing Ts. Accumulation of the flash and Still CCD 107 is started. If the timing Ts is outside the period Tf, the storage of the flash of the strobe device 109 and the still CCD 107 is started after the storage period of the next field is completed.

  As a result, at the time of still image imaging using the strobe device 109, imaging by the still CCD 107 is started at a timing delayed by ΔT + Tc at the maximum after the still image trigger switch 104 is pressed. However, there is no practical problem because at least this period is a time that humans cannot perceive or cannot perceive.

  As described above, according to the present embodiment, in the two-plate image pickup apparatus capable of simultaneously recording moving images and still images, the strobe device 109 for taking still images is taken within the non-accumulation period of the moving image shooting CCD. By making the flash period exist, stable moving image recording can be realized without the moving image being affected by the flash by the flash device.

  In the above example, the example in which the camera microcomputer 111 controls according to the flowchart of FIG. 4 has been described. However, the timings T1 and T3 defining the period Tf in FIG. 3B are unique during moving image shooting by the Movie CCD 105. To be determined. When this is realized by hardware, for example, it may be realized by a configuration as shown in FIG.

  In the figure, 51 is a counter that counts a predetermined clock and is reset by an accumulation start signal (one of signals output from the CCD drive control unit 106) of the movie CCD 105. It is also possible to reset with a signal indicating the start of reading of the movie CCD 105. 52 and 53 are registers for setting numerical values corresponding to the timings T1 and T3, and 54 and 55 are comparators. The comparator 54 outputs a “1 (High)” signal when the value counted by the counter 51 is larger than the value set in the register 52, and outputs a “0 (low)” signal otherwise. The comparator 55 outputs “1” when the value counted by the counter 51 is less than or equal to the numerical value set in the register 53, and outputs “0” otherwise. 56 is an AND circuit, which outputs “1” only when the signals from the comparators 54 and 55 are both “1”, and outputs “0” otherwise.

  According to such a configuration, a value based on the accumulation period of the movie CCD 105 during moving image shooting is set in the registers 51 and 52, and only “1” is set during the period corresponding to the period Tf in FIG. Can be generated. Therefore, the output signal of the AND circuit 56 can use the flash permission of the strobe device 109 and the Still CCD 107 as a signal for starting accumulation.

  The circuit configuration in FIG. 5 functions only when the strobe device 109 is used. When the strobe device 109 is not used, the signal from the AND circuit 56 is not used, and accumulation of the flash of the strobe device 109 and the still CCD 107 is started when the still image trigger switch 104 is pressed. . FIG. 5 is an example, and the present invention is not limited thereby.

  In the embodiment, the flash device 109 is described as an example of the flash light source. However, the flash device 109 may be applied to an AF auxiliary light (flash light for distance measurement) source when shooting a still image. You may apply to the apparatus which utilizes both auxiliary light. In the case of a device that uses AF auxiliary light, normally, the AF auxiliary light is emitted when the still image trigger switch 104 is half-pressed. When full pressing is performed, the same operation as in the above embodiment may be performed.

<Second Embodiment>
In the above embodiment, the image capturing timing of the still image and the flash timing of the strobe device 109 are controlled without affecting the recording of the moving image. When the flash period by the strobe device 109 is ΔT and the moving image accumulation period is Tc, imaging by the still CCD 107 is started at a timing delayed by ΔT + Tc at the maximum after the trigger switch 104 for the still image is pressed. It was a thing.

  However, in the device in which the flash period ΔT of the flash device 109 can be lengthened, the time “ΔT + Tc” results in a long time, and in some cases, the time from when the still image trigger switch 104 is pressed until the actual flashing starts. The possibility of being uncomfortable cannot be denied.

  Therefore, in the second embodiment, an example will be described in which the period Tf in the above embodiment is ensured as long as possible.

  In order to simplify the description, the apparatus configuration is assumed to be the same as that in FIGS. 1 and 2 of the first embodiment. Refer to the schematic configuration diagram in FIG. 1, the apparatus perspective view in FIG. 2, and the flowchart in FIG. However, still image shooting processing in the imaging apparatus according to the second embodiment will be described.

  When the still image trigger switch 125 is pressed by the user, a still image shooting request is made (step S202). Here, the camera microcomputer 111 determines whether or not the moving image shooting / recording is in progress (step S203). If the moving image shooting / recording is not in progress, the camera microcomputer 111 sends a drive command (storage command) to the Still CCD drive control unit 108 to The CCD 107 is controlled to take a still image as usual (step S208). At this time, it does not matter whether or not the flash device 109 is flashed.

  If it is determined that the moving image shooting / recording is being performed, the camera microcomputer 111 determines whether to use the strobe device 109 for still image shooting (step S204). When the strobe device 109 is not used, the camera microcomputer 111 sends a command to the Still CCD drive control unit 108 to control the Still CCD 107 and to perform still image shooting as usual (step S208).

  On the other hand, when it is determined (detected) that the still image trigger switch 125 has been pressed by the user during moving image recording, it is determined whether or not the current non-accumulation period (details will be described later) of the movie CCD 105 is present. Wait for the normal non-accumulation period.

  When it is determined that the normal non-accumulation period of the Movie CCD 105 has been reached or the user has pressed the still image trigger switch 125 within the normal non-accumulation period, the camera microcomputer 111 performs the CCD drive control unit for Movie A command is sent to 106, the movie CCD 105 is maintained in the non-accumulation period (step S210), a command is sent to the strobe drive control unit 110, flashing of the strobe device 109 is started (S206), and still CCD drive control is performed. A command is sent to the unit 108 to start the accumulation of the still CCD 107, thereby starting still image shooting (S207).

  Next, the camera microcomputer 111 determines whether or not the flash period of the flash device 109 has ended (step S211). When the strobe device 109 is driven, the flash period is determined from the exposure amount at that time, so that the elapsed time can be determined by counting the clock with a counter. When it is determined that the strobe flashing period has ended, it is determined whether or not the elapsed time T from the start of the non-accumulation period has reached the normal non-accumulation period, and waits until it reaches the normal accumulation period (step S212). If it is determined that it has been reached, the movie CCD 105 is released from the non-accumulation period state, accumulation of the next field is started, and normal operation is restored (S209).

  The above-mentioned “normal non-accumulation period” corresponds to the period Tr of FIG. 3 of the first embodiment described above.

  Based on this point, the accumulation period of the movie CCD 105 and the still CCD 107 and the light emission period of the flash device 109 in the second embodiment will be described with reference to the schematic timing diagram of FIG. Note that, when a still image is captured and recorded without using the strobe device 109, the description is omitted because it is the same as in the first embodiment.

  FIG. 7A shows a case where it is decided to use the strobe device 109 and the still image trigger switch 125 is pressed during the accumulation period of the movie CCD 105. In this case, as in the first embodiment, after the accumulation period of the movie CCD 105 ends, a control command is output to the strobe drive control unit 110 to flash the strobe device 109 and a still image is displayed. An instruction is sent to the CCD drive control unit 108 and the accumulation of the still CCD 107 is started to start still image shooting.

  FIG. 7B shows a timing chart when the still image trigger switch 125 is pressed during the normal non-accumulation period (reading period) of the movie CCD 105.

  In this case, at the timing when the still image trigger switch 125 is pressed, a control command is output to the strobe drive control unit 110 to flash the strobe device 109, and a command is sent to the CCD drive control unit 108 for still images. The still image shooting is started by starting the accumulation of the still CCD 107. However, when the flash period is completed, there is a possibility that shooting of the next field may be started by the movie CCD 105, so the non-accumulation period of the movie CCD 105 is maintained until the flash period is completed. With the end of the flash period as a trigger, accumulation of the next field by the movie CCD 105 is started. For this reason, in FIG. 7B, the non-accumulation period when the still image trigger switch 125 is pressed may be longer than the normal non-accumulation period Ts by an α period. It can be easily understood that this α period varies in the range of 0 to ΔT.

  In the first embodiment, the flash device 109 starts flashing after waiting for a maximum of Ts + ΔT after the still image trigger switch 125 is pressed, whereas according to the second embodiment, the waiting time is maximum. This means that during the Ts period, the flash period of the strobe device 109 is actually shortened by that much after the still image trigger switch 125 is depressed, and a high response can be obtained. In particular, the flashing period of the strobe device 109 is not fixed, and the present invention is particularly advantageous for an imaging apparatus that can lengthen the period.

  In the situation as shown in FIG. 7B, the moving image field interval may change under the influence of still image shooting. However, by interposing an appropriate buffer memory, the magnetic tape can be changed. Since recording is performed at a normal field interval, the field interval does not change during reproduction.

  As described above, according to the second embodiment, as in the first embodiment described above, in the two-plate type imaging apparatus capable of simultaneously recording a moving image and a still image, the non-moving image capturing CCD is used. By making the flash period of the flash device 109 for still image shooting exist within the accumulation period, it is possible to realize stable moving image recording without the moving image being affected by the flash by the flash device. it can. In particular, according to the second embodiment, a period from when the still image trigger switch 125 is pressed to when the flash device 109 actually flashes is shortened, and an operating environment in which a sense of incongruity is unlikely to occur is provided. It becomes possible.

  In the second embodiment, the strobe device 109 has been described as an example of a flash light source. However, it may be applied to an AF auxiliary light (flash light for ranging) source when taking a still image. You may apply to the apparatus using both light and AF auxiliary light. In the case of a device that uses AF auxiliary light, normally, the AF auxiliary light is emitted when the still image trigger switch 104 is half-pressed. When full pressing is performed, the same operation as in the second embodiment may be performed.

  Further, in the embodiment, the description has been given of the so-called front film sync mode in which strobe light emission is performed in the previous stage within the accumulation period of the Still CCD 107 when capturing a still image, but at the rear end stage in the accumulation period of the Still CCD 107. A rear film sync mode that emits strobe light may be used. However, in the case of the rear film sync mode, the strobe light emission timing is further delayed, and the strobe light emission timing must be determined in accordance with the accumulation end timing, so the control must be complicated. The leading-film synchro mode described in the above item is more preferable.

  In the first and second embodiments, the example in which the strobe device is provided integrally with the imaging device has been described. However, the strobe device is attached to the removable imaging device as an option. It may function when detected (which can be realized with an appropriate sensor).

  In the first and second embodiments, a magnetic tape (magnetic tape cassette) is described as an example of a moving image recording medium. However, a disk-shaped recording medium such as an optical disk may be used.
