Can do.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram showing a circuit configuration of a digital camera 1 common to the respective embodiments of the present invention. The digital camera 1 has a still image shooting function and a moving image shooting function, and includes a CCD 2 and a DSP / CPU 3, and the CCD 2 is provided with a primary color filter with a Bayer array in the photosensitive portion. . The DSP / CPU 3 is a one-chip microcomputer that has various digital signal processing functions including image data compression / decompression processing and controls each part of the digital camera 1.

  The DSP / CPU 3 is connected to a TG (Timing Generator) 4 that drives the CCD 2 at a set frame rate such as “60 f / s”. The TG 4 corresponds to the optical image of the subject output from the CCD 2. A unit circuit 5 to which an analog imaging signal is input is connected. The unit circuit 5 includes a correlated double sampling circuit (CDS circuit) that reduces drive noise of the CCD 2 included in the imaging signal output from the CCD 2, and an automatic gain control circuit (AGC circuit) that adjusts the gain of the signal after noise reduction. ) Including an A / D converter that converts the gain-adjusted signal into a digital signal, converts an analog imaging signal input from the CCD 2 into a digital image signal, and sends the digitized Bayer data to the DSP / CPU 3.

  A display device 6 and a key input unit 7 are connected to the DSP / CPU 3, and a buffer memory (DRAM) 11, a ROM 12, a storage memory 13, and an input / output interface 14 are connected via an address / data bus 10. Yes. The buffer memory 11 is a buffer for temporarily storing the Bayer data and the like, and is also used as a working memory for the DSP / CPU 3.

  That is, the DSP / CPU 3 performs processing such as pedestal clamping on the Bayer data sent from the unit circuit 5 and then converts the data into RGB data, and further converts the RGB data into a luminance (Y) signal and a color difference (UV). Convert to signal. The YUV data converted by the DSP / CPU 3 stores data for one frame in the buffer memory 11. One frame of YUV data stored in the buffer memory 11 is sent to the display device 6, where it is converted into a video signal and then displayed as a through image.

  Further, when the shutter key operation by the user is detected in the still image shooting mode, the shooting process A executed in the first embodiment and the shooting process B executed in the second embodiment to be described later are selectively performed. To do. That is, in the shooting process A, the image data (YUV data) for one frame stored in the buffer memory 11 when the shutter key is pressed is encoded by the DSP / CPU 3 after data compression by the JPEG method, etc. After being filed in the memory 11, it is recorded in the storage memory 13. In the shooting process B, when a shutter key operation is detected, the still image shooting process is executed by switching the CCD 2 and the unit circuit 5 to a drive method and drive timing for shooting a still image different from that for through-image shooting. Then, one frame of YUV data is stored in the buffer memory 11 by this still image shooting process, and the stored one frame of YUV data is encoded by the DSP / CPU 3 after data compression by the JPEG method or the like, and the buffer memory 11 And recorded as still image data (still image file) in the storage memory 13 via the address / data bus 10.

  Also, when a moving image shooting start instruction is detected by the first shutter key operation by the user in the moving image shooting mode, moving image processing is started, and a plurality of operations until the moving image shooting end instruction is detected by the second shutter key operation are detected. The YUV data for the frame is stored in the buffer memory 11. The YUV data for a plurality of frames stored in the buffer memory 11 are sequentially sent to the DSP / CPU 3, encoded after data compression by a predetermined MPEG codec, and framed via the buffer memory 11 and the address / data bus 10. The file name is assigned as data and written to the storage memory 13. Further, the DSP / CPU 3 expands the still image or moving image data read from the storage memory 13 during reproduction of the still image or moving image, and stores it in the image data work area of the buffer memory 11 as still image data or moving image frame data. expand.

  The display device 6 includes a color LCD and its driving circuit, and displays the subject image captured by the CCD 2 as a through image when in the shooting standby state, and is read out from the storage memory 13 and expanded when the recorded image is played back. The recorded image is displayed. The key input unit 7 includes a plurality of operation keys such as a shutter key, a mode setting key, a slow button, and a power key, and outputs a key input signal corresponding to the key operation by the user to the DSP / CPU 3.

  The charge accumulation time set by the DSP / CPU 3 based on the frame rate is supplied as a shutter pulse to the CCD 2 via the TG 4, and the charge accumulation time, that is, the exposure time is controlled by operating the CCD 2 in accordance with this. That is, the CCD 2 functions as an electronic shutter. Further, the ROM 12 stores a program shown in a flowchart to be described later and various programs necessary for functioning as a digital camera.

  Note that the digital camera 1 includes the input / output interface 14, and thus can be connected to an external device such as a printer, a personal computer, or a TV receiver via the input / output interface 14.

  FIG. 2 is a flowchart illustrating a processing procedure according to the first embodiment. When the power key of the key input unit 7 is operated to turn on the power, the DSP / CPU 3 executes processing as shown in this flowchart in accordance with a program stored in the ROM 12. That is, it is determined whether or not the still image shooting mode is set by operating a mode setting key provided in the key input unit 7 (step S101). If the still image shooting mode is not set, it is determined whether or not the display frame rate setting mode is set (step S102), and if it is not set, the process proceeds to another mode process.

  When the display frame rate setting mode is set, as will be described later, a frame rate selection composed of a screen displaying a plurality of types of frame rates lower than “60 f / s” which is the imaging frame rate in the present embodiment. A screen is displayed on the display device 6 (step S103). Then, one of the frame rates selected by the operation of the key input unit 7 from this frame rate selection screen is set as the display frame rate and stored in the buffer memory 11 (step S104).

  On the other hand, if the still image shooting mode is set as a result of the determination in step S101, the TG 4 is controlled to start driving the CCD 2 at “60 f / s” which is the imaging frame rate of the present embodiment. Then, based on the frame image data obtained at this frame rate, the through image is displayed on the display device 6 in substantially real time (step S106). Here, it is assumed that only one frame of image data is stored in the buffer memory 11, and the frame image data sequentially obtained at the above-described frame rate is updated and stored (overwritten) in the buffer memory 11. It is assumed that the image data updated and stored in the buffer memory 11 is immediately displayed sequentially as a through image on the display device 6. Next, it is determined whether or not the shutter key is pressed (step S107). If the shutter key is not pressed, it is determined whether or not the slow button is pressed (step S109). If the slow button is not pressed, the process returns to step S106.

  Therefore, when there is no operation of the shutter key and the slow button, the loop of S106 → S107 → S109 → S106 is repeatedly executed, and as shown in FIG. 3, the imaging frame rate = display frame rate is set, and the display device On the display screen 6, a through image that changes at the imaging frame rate is displayed. In this state, if the shutter key is pressed, the determination in step S107 is YES, and the process proceeds to step S108, and is stored in the buffer memory 11 when the shutter key is pressed (that is, the display device 6). The image data for one frame (displayed in FIG. 5) is encoded after data compression by the JPEG method or the like, encoded into a file in the buffer memory 11, and then recorded in the storage memory 13. Therefore, the digital camera 1 according to the present embodiment functions in the same manner as a general digital camera and can perform normal shooting until the slow button is pressed.

  However, when the user sees the through image whose display is changed by the processing in step S106 and determines that it is difficult to press the shutter key at a photo opportunity with his own response speed capability, or the subject moves faster. If it is determined that it is difficult to press the shutter key at the photo opportunity, the slow button is pressed. Thereby, determination of step S109 becomes YES. Therefore, the process proceeds from step S109 to step S110, and a process of storing the frame image data obtained at the imaging frame rate in the buffer memory 11 without sequentially updating (overwriting) is started (step S110). Thereby, as shown in FIG. 3, a plurality of frame image data obtained at the imaging frame rate (“60 f / s”) are sequentially stored in the buffer memory 11.

  Next, frame image data is displayed and selected from the buffer memory 11 at the display frame rate set in step S104 in the order of imaging and read (step S111), and an image based on the read frame image data is displayed on the display device 6. (Step S112). Here, out of a plurality of frame image data stored in the buffer memory 11, for the frame image data that has been displayed on the display device 6, an erasure (deletion) process is executed at the time of completion, Assume that processing for permitting update (overwriting) storage is executed. Subsequently, it is determined whether or not the shutter key is pressed (step S113). If the shutter key is not pressed, it is determined whether or not the slow button is pressed (step S115). If the slow button is not pressed, the process returns to step S111.

  Therefore, when the shutter key and the slow button are not pressed, the loop of S111 → S112 → S113 → S115 → S111 is repeatedly executed, and the subject image based on the frame image data is displayed on the display device 6 at the display frame rate. Is displayed. At this time, since the display frame rate is lower than the imaging frame rate as described above, the subject image is slowly displayed on the display screen of the display device 6 as shown in FIG.

  In this state, if the shutter key is pressed, the determination in step S113 is YES, and the process proceeds to step S114. When the shutter key is pressed, the data is read from the buffer memory 11 (display selected). The frame image data, that is, the frame image data corresponding to the image displayed on the display device 6 is encoded after data compression by the JPEG method or the like, filed in the buffer memory 11, and then recorded in the storage memory 13 (step) S114). The recording process in step S114 is executed every time the shutter key is pressed in a state where the loop of steps S111 to S115 is executed (every time step S113 becomes YES). Therefore, as shown in FIG. 3, in response to the pressing of the shutter key during this time, “shutter 1” to “shutter (n)”, each frame of “record 1” to “record (n)” is stored in the storage memory 13. Image data will be recorded.

  When the user presses the slow button again, the determination in step S115 is YES. Accordingly, the process proceeds to step S116, and after executing the deletion (deletion) process for all the frame image data stored in the buffer memory 11 or the process for permitting the update (overwrite) storage, the process returns to step S106. At this time, as shown in FIG. 3, the state of the imaging frame rate = the display frame rate is established again, and a through image that changes at the imaging frame rate is displayed on the display screen of the display device 6.

  FIG. 4 is a flowchart illustrating a processing procedure according to the second embodiment. When the power key of the key input unit 7 is operated to turn on the power, the DSP / CPU 3 executes processing as shown in this flowchart in accordance with a program stored in the ROM 12. That is, it is determined whether or not the still image shooting mode is set by operating a mode setting key provided in the key input unit 7 (step S201). If the still image shooting mode is not set, it is determined whether or not the display frame rate setting mode is set (step S202). If not set, the process proceeds to another mode process.

  When the frame rate setting mode is set, as will be described later, a display frame including a screen displaying a plurality of types of frame rates lower than “60 f / s” which is a normal imaging frame rate in the present embodiment. A rate selection screen is displayed on the display device 6 (step S203). Then, one of the frame rates selected by the operation of the key input unit 7 from this frame rate selection screen is stored in the buffer memory 11 as a display frame rate (step S204).

  On the other hand, if the result of determination in step S201 is that the still image shooting mode has been set, TG4 is controlled to start driving the CCD 2 at “60 f / s”, which is the normal imaging frame rate (step S205). ), A through image is displayed on the display device 6 based on the frame image data obtained at this frame rate (step S206). Here, it is assumed that only one frame of image data is stored in the buffer memory 11, and the frame image data sequentially obtained at the above-described frame rate is updated and stored (overwritten) in the buffer memory 11. It is assumed that the image data updated and stored in the buffer memory 11 is immediately displayed sequentially as a through image on the display device 6. Next, it is determined whether or not the shutter key has been pressed (step S207). If the shutter key has not been pressed, it is determined whether or not the slow button has been pressed (step S209). If the slow button is not pressed, the process returns to step S206.

  Therefore, when the shutter key and the slow button are not pressed, the loop of S206 → S207 → S209 → S206 is repeatedly executed, and the normal imaging frame rate = display frame rate state is obtained as shown in FIG. The display screen of the display device 6 displays a through image that changes at the imaging frame rate. In this state, if the shutter key is pressed, the determination in step S207 is YES, and the process proceeds to step S208 to execute still image shooting / recording processing. In other words, as described above, the still image shooting process is executed by temporarily switching the CCD 2 and the unit circuit 5 to a still image shooting drive system and drive timing different from those for through-image shooting. The YUV data for one frame is stored in the buffer memory 11, and the stored YUV data for one frame is encoded after being compressed by the DSP / CPU 3 using the JPEG method or the like and converted into a file in the buffer memory 11. The image data is recorded in the storage memory 13 via the address / data bus 10 as still image data (still image file).

  However, when the user sees the through image whose display is changed by the process of step S206 and determines that it is difficult to press the shutter key at the photo opportunity with his own response speed capability, or the subject moves faster. If it is determined that it is difficult to press the shutter key at the photo opportunity, the slow button is pressed. Thereby, determination of step S209 becomes YES. Accordingly, the process proceeds from step S209 to step S210, and frame image data is displayed and selected from the buffer memory 11 at the display frame rate set in step S204 in the order of imaging and read (step S210), and based on the read frame image data. An image is displayed on the display device 6 (step S211). Here, out of a plurality of frame image data stored in the buffer memory 11, for the frame image data that has been displayed on the display device 6, an erasure (deletion) process is executed at the time of completion, Assume that processing for permitting update (overwriting) storage is executed.

Subsequently, the countdown display process is executed (step S212). That is, in the present embodiment, the frame image data is slowly displayed at the display frame rate only for a predetermined time of 30 seconds, and the slow display is forcibly terminated when 30 seconds have elapsed. For this reason, in this step S212, the initial value “30 seconds” is displayed, and the countdown display process is performed every time 1 second elapses, and the remaining time of the slow display is displayed as a warning.
The slow display time (30 seconds) may be arbitrarily set by a user setting operation, or may be calculated and set based on a set display frame rate. Further, a warning display to that effect may be displayed when the remaining 10 seconds are reached, or the countdown display may be started when the remaining 10 seconds are reached.

  Subsequently, it is determined whether or not the shutter key is pressed (step S212). If the shutter key is not pressed, it is determined whether or not the slow button is pressed or whether the slow display time is over (step S215). If the slow button is not pressed and the time is not over, the process returns to step S210.

  Therefore, when the shutter key and the slow button are not pressed, the loop of S210 → S211 → S212 → S215 → S210 is repeatedly executed, and the subject image based on the frame image data is displayed on the display device 6 at the display frame rate. Is displayed. At this time, as described above, since the display frame rate is lower than the imaging frame rate, the subject image is slowly displayed on the display screen of the display device 6 as shown in FIG.

  In this state, if the shutter key is pressed, the determination in step S213 is YES, and the process proceeds to step S214. When the shutter key is pressed, it is read from the buffer memory 11 (display is selected). The frame image data, that is, the frame image data corresponding to the image displayed on the display device 6 is encoded after data compression by the JPEG method or the like, filed in the buffer memory 11, and then recorded in the storage memory 13 (step) S214). The recording process in step S214 is executed every time the shutter key is pressed (when step S213 becomes YES) in a state where the loop of steps S210 to S215 is being executed. Accordingly, as shown in FIG. 5, in response to pressing of the shutter key during this time, “shutter 1” to “shutter (n)”, each frame of “record 1” to “record (n)” is stored in the storage memory 13. Image data will be recorded.

  If the user presses the slow button again or the time is over, the determination in step S215 is YES. Therefore, the process proceeds to step S216, and the remaining non-displayed number N not displayed in step S211 is detected in the frame image data stored in the buffer memory 11 (step S216). Subsequently, using this detected N, a display frame rate of 1 / (N + 60) is calculated (step S217). Further, the remaining undisplayed image data is displayed on the display device 6 at the calculated display frame rate 1 / N (step S218).

  That is, in this embodiment, as shown in FIG. 5, the display time of the non-displayed image data (N) is fixedly set to 1 second, and all the non-displayed images (steps within this 1 second are set). After the slow button press is detected in S216, the buffer memory 11 is continuously displayed at the imaging frame rate. However, the user may be able to set the display time of this undisplayed image. Further, the display frame rate of the undisplayed image may be selectively set by the user. In this case, the display time of the non-displayed image changes according to the number of non-displayed images and the display frame rate of the non-displayed image selectively set by the user. It is an essential condition that the rate is at least a rate higher than the imaging frame rate, that is, a rate much higher than the display frame rate set in step S204. Further, a fixed rate determined in advance may be used as the display frame rate of the undisplayed image. In this case, the display time of the undisplayed image changes according to the number of undisplayed images.

  Further, after executing deletion (deletion) processing for all frame image data stored in the buffer memory 11 or processing for permitting update (overwriting) storage in step S219, the processing returns to step S206. Therefore, as shown in FIG. 5, the imaging frame rate = display frame rate again after 1 second, and a through image that changes at the imaging frame rate is displayed on the display screen of the display device 6.

  In the embodiment described above, the frame rate can be set by the user selecting from a screen displaying a plurality of types of frame rates. However, a low frame rate suitable for slow display in the manufacturer is fixed. And reading from the buffer memory 11 may be performed at this frame rate. In the embodiment, the start and release of the slow display are performed in response to the same slow button operation, but may be performed in response to different operations. In the embodiment, the start and release of the slow display are performed in response to the slow button operation. However, the shutter key is pressed halfway (1 step press) and fully pressed (2 steps press). The shutter key can be used, and the slow display is started when a half-pressing operation of the shutter key is detected, or the slow display is canceled when the release of the half-pressing operation of the shutter key is detected. Good.
