  The shooting mode key 9 is operated automatically from the power-off state to automatically turn on and shift to the still image shooting mode. On the other hand, by repeatedly operating from the power-on state, the still image mode and the moving image mode are switched. Set cyclically. The still image mode is a mode for photographing a still image. The moving image mode is a mode for shooting a moving image.

  The shutter key 8 is commonly used for these photographing modes. That is, in the still image mode, a still image is taken at the timing when the shutter key 8 is pressed. In the moving image mode, shooting of a moving image is started at the timing when the shutter key 8 is pressed, and shooting of the moving image is ended when the shutter key 8 is pressed again.

  When the playback mode key 10 is operated from the power-off state, the playback mode key 10 is automatically turned on to enter the playback mode.

  The strobe key 12 is operated when switching the light emission mode of the strobe light emitting unit 6. The menu key 13 is operated when selecting various menu items. The ring key 14 is formed by integrally forming the upper, lower, left, and right direction keys 15a to 15d, and the set key 16 located at the center of the ring key 14 is used to set an item selected at that time.

  Although not shown, the digital camera 1 has a memory card slot for attaching / detaching a memory card used as a recording medium, a serial interface connector for connecting to an external personal computer, etc., for example, USB (Universal). (Serial Bus) connector and the like are provided.

  FIG. 2 is a block diagram showing an electronic circuit configuration of the digital camera 1.

  In the digital camera 1, a lens optical system 22 including a focus lens and a zoom lens (not shown) constituting the photographing lens 3 is provided so as to be movable within a predetermined range in the optical axis direction by driving a motor 21. A CCD 23, which is an image sensor, is disposed behind the optical axis. The CCD 23 receives light passing through the photographing lens 3 and acquires image data corresponding to the amount of received light.

  In the recording mode, which is the basic mode, the CCD 23 is scanned and driven by a timing generator (TG) 24 and a driver 25, and outputs a photoelectric conversion output corresponding to a light image formed at regular intervals for one screen.

  The photoelectric conversion output of the CCD 23 is appropriately gain-adjusted for each primary color component of RGB in the state of an analog value signal, sampled and held by the sample hold circuit 26, and converted into digital data by the A / D converter 27. The In the color process circuit 28, color process processing including pixel interpolation processing and γ correction processing is performed to generate digital luminance signals Y and color difference signals Cb, Cr, which are sent to a DMA (Direct Memory Access) controller 29. Is output.

  The DMA controller 29 once uses the luminance signal Y and the color difference signals Cb and Cr output from the color process circuit 28 by using the composite synchronization signal, memory write enable signal, and clock signal from the color process circuit 28 once. And the DMA transfer to the DRAM 31 used as the buffer memory via the DRAM interface (I / F) 30.

  The control unit 32 includes a microcomputer including a CPU, a ROM that stores an operation program executed by the CPU, and a RAM that is used as a work memory. The control unit 32 controls the entire digital camera 1, and after the DMA transfer of the luminance and color difference signals to the DRAM 31 is completed, the luminance and color difference signals are read from the DRAM 31 via the DRAM interface 30 and the VRAM controller 33 is read. To the VRAM 34.

  The digital video encoder 35 periodically reads the luminance and color difference signals from the VRAM 34 via the VRAM controller 33, generates a video signal based on these data, and outputs the video signal to the display unit 19.

  As described above, the display unit 19 functions as a monitor display unit (electronic finder) at the time of shooting. By performing display based on the video signal from the digital video encoder 35, the display unit 19 captures from the VRAM controller 33 at that time. An image based on the image information is displayed in real time.

  As described above, when the shutter key 8 is pressed at a timing when, for example, it is desired to take a still image while the current image is displayed on the display unit 19 in real time as a monitor image, a trigger signal is generated.

  In response to the trigger signal, the control unit 32 immediately stops the path from the CCD 23 to the DRAM 31 immediately after the DMA transfer of the luminance and color difference signals for one screen captured from the CCD 23 to the DRAM 31 is completed. , Transition to the record storage state.

  In this recording and storage state, the control unit 32 outputs the luminance and color difference signals for one frame written in the DRAM 31 to 8 pixels × 8 pixels for each of Y, Cb, and Cr components via the DRAM interface 30. The data is read out in units called basic blocks, written in a JPEG (Joint Photographic Coding Experts Group) processing block existing in the image processing unit 37, and the image processing unit 37 uses ADCT (Adaptive Discrete Cosine Transform: adaptive discrete cosine transform). ), The data is compressed by a process such as Huffman coding, which is an entropy coding method.

  The obtained code data is read out from the image processing unit 37 as a data file of one image and written in the recording memory 38. The memory 38 includes a memory card that is detachably mounted as a recording medium in addition to an internal memory such as a flash memory built in the main body in advance. With the compression processing of the luminance and color difference signals for one frame and the completion of writing all the compressed data to the memory 38, the control unit 32 activates the path from the CCD 23 to the DRAM 31 again.

  A USB interface (I / F) 39 and a strobe drive unit 40 are further connected to the control unit 32.

  The USB interface 39 performs communication control when image data and other information are transmitted / received to / from other information terminal devices such as a personal computer connected by wire via a USB connector. The strobe drive unit 40 charges a large-capacitance capacitor for strobe (not shown) at the time of photographing, and then drives the strobe light emitting unit 6 to flash based on the control from the control unit 32.

  In addition to the shutter key 8 described above, the key input unit 36 includes a power key 7, a shooting mode key 9, a playback mode key 10, a strobe key 12, a menu key 13, a ring key 14, and direction keys 15a to 15d. , Set key 16, zoom keys 17a and 17b, angle adjustment keys 18a and 18b, etc., and signals accompanying these key operations are sent directly to control unit 32.

  In addition, when shooting a moving image instead of a still image, a moving picture processing group (MPEG) or a motion processing block existing in the image processing unit 37 described above when the shutter key 8 is pressed. -Captured moving image data is compressed and recorded in the memory 38 by a method such as JPEG (Joint Photographic Experts Group). In this case, in the case of moving image recording with sound, the sound data is integrated into the compressed moving image data and recorded in the memory 38. When the shutter key 8 is operated again, the recording of the moving image data is finished.

  On the other hand, in the playback mode, which is the basic mode, the control unit 32 selectively reads out the image data recorded in the memory 38, and the image processing unit 37 compresses the image data in a procedure that is completely opposite to the procedure of data compression in the recording mode. Decompress the image data. The decompressed image data is held in the DRAM 31 via the DRAM interface 30, and then the content held in the DRAM 31 is stored in the VRAM 34 via the VRAM controller 33. The image data is periodically read out from the VRAM 34. A video signal is generated and reproduced and output by the display unit 19.

  If the selected image data is not a still image but a moving image, the multiple frames of still image data that make up the moving image data are played back and displayed sequentially in chronological order, and all the still image data is played back. For example, the top still image data is displayed until the next playback instruction is given.

  Next, the operation of the embodiment will be described.

  Note that the processing shown in the following flowchart is executed when the control unit 32 which is a microcomputer mounted on the digital camera 1 reads a program stored in a ROM or the like.

  FIG. 3 is a flowchart showing a processing operation at the time of photographing by the digital camera 1 in the embodiment. In addition, in this digital camera 1, both still image shooting and moving image shooting are possible as described above, and the present invention can be applied to either shooting, but here, in order to simplify the description, A description will be given assuming still image shooting.

  When the still image shooting mode is set by operating the shooting mode key 9 after the power is turned on, the image data of the subject is obtained through the imaging system including the CCD 23 (step S11). The control unit 32 displays the entire range of the image data on the screen of the display unit 19 as a through image (step S12). At that time, as shown in FIG. 4, the control unit 32 displays the cutout range of the partial image to be recorded as the shooting target in the through image using a cutout frame (trimming frame) P that is a specific display form. (Step S13).

  In the initial state, the cutout frame P is set at the center position of the image data. The cutout frame P (that is, the cutout range of the partial image) is basically a rectangle, but may be another shape such as a circle, and the shape is not particularly limited.

  When the user performs an AF operation such as half-pressing the shutter key 8 (step S14), the control unit 32 executes an autofocus process (step S15), and the closest subject is in focus. The position on the screen (focus position) is detected (step S16).

  Specifically, for example, in the case of the contrast method, the focus lens included in the lens optical system 22 shown in FIG. 2 is moved in the optical axis direction, and the contrast of the image formed on the CCD 23 is checked for each area of the image. The position where the contrast appears most intense is detected as the in-focus position. When the in-focus position is detected in this way, the control unit 32 sets the center of the cutout frame P at the in-focus position (step S17). The state at this time is shown in FIG. F in the figure is the in-focus position obtained by the autofocus process, and the center of the cutout frame P is automatically set at the in-focus position F.

  Subsequently, when the user instructs angle adjustment by operating the angle adjustment keys 18a and 18b (Yes in Step S18), the control unit 32 changes the angle of the cutout frame P according to the adjustment instruction, and as shown in FIG. The display of the cutout frame P after the change is updated (step S19). The example of FIG. 6 shows a case where the angle is changed by rotating the cutout frame P clockwise toward the screen with the focus position F as the center axis by pressing the angle adjustment key 18a.

  When the user instructs position adjustment by operating the direction keys 15a to 15d of the ring key 14 (Yes in step S20), the control unit 32 changes the position of the cutout frame P according to the adjustment instruction, and is shown in FIG. Thus, the display of the cutout frame P after the change is updated (step S21). In the example of FIG. 7, a case where the clipping frame P is moved in the lower right direction toward the screen by pressing the right direction key 15 a and the lower direction key 15 b is illustrated.

  When the user instructs the size adjustment by operating the zoom keys 17a and 17b (Yes in step S22), the control unit 32 changes the size of the cutout frame P according to the adjustment instruction, and after the change as shown in FIG. The display of the cutout frame P is updated (step S23). The example of FIG. 8 shows a case where the cutout frame P is enlarged by pressing the zoom key 17a.

  As described above, the cut-out angle, position, and size of the partial image to be imaged can be arbitrarily changed by a predetermined operation while viewing the screen of the display unit 19. Here, when the shutter key 8 is pressed to give a shooting instruction (Yes in step S23), the control unit 32 executes shooting processing at the timing of pressing the shutter key 8, and cuts out the currently displayed image data from the image data. A partial image in the frame P is cut out and captured as a captured image (step S24), compressed by a predetermined method, and recorded in the memory 38 (step S25).

  Note that in this shooting process, when a shooting instruction is issued by pressing the shutter key 8, the driving method of the CCD 23 is switched to the still image shooting mode at that time, so that the high image quality obtained by the CCD 23 can be obtained. A method of capturing and recording image data as a photographed image and a method of using the immediately preceding through image (low-quality image data) for recording when the shutter key 8 is pressed in the through display state. There is a street. In the circuit configuration shown in FIG. 2, the operation using the former method has been described, but the present invention is not limited to either method.

  FIG. 9 is a diagram showing an example of a photographed image recorded in the memory 38, and shows a case where a partial image in the clipping frame P is captured as a subject to be photographed by pressing the shutter key 8 in the display state of FIG. Yes.

  As described above, when a part of image data is cut out and recorded as a shooting target, the cutting range of the partial image to be shot can be arbitrarily changed by a user operation. Even when the digital camera 1 is in a fixed state, the subject can be freely adjusted and photographed within the range of the screen.

  In this case, since not only the position of the subject in the vertical and horizontal directions but also the angle can be adjusted, for example, when the digital camera 1 is fixed while being tilted with respect to the ground, the tilt of the subject is displayed on the screen. The advantage is that you can easily correct and shoot. Therefore, when combined with position adjustment, size adjustment (digital zoom), etc., the degree of freedom of position adjustment of the subject is remarkably increased, and a desired captured image can be obtained flexibly corresponding to various scenes.

  Further, when the digital camera 1 has an AF function, the center of the clipping range is automatically set at the in-focus position detected by the AF function. It is possible to easily set a cutout range at the position and record an image within the range as a shooting target.

  In the above-described embodiment, the focus is automatically set to the closest subject position by the AF function. However, the user may arbitrarily focus by a manual operation. In that case, since the manual operation of the position adjustment shown in step S20 can be used as the focus adjustment operation, there is an advantage that the extraction range can be set to a desired subject position faster.

  In the above-described embodiment, the cutout frame P indicating the cutout range of the partial image is displayed while the entire image is displayed through. However, only the partial image in the cutout frame P can be displayed through on the screen. good.

  FIG. 10 is a diagram showing a display example. FIG. 10A shows an initial state, and FIG. 10B shows a state at the time of AF.

  That is, in the initial state, the image data of the subject is obtained by the imaging system including the CCD 23, and an image within a predetermined range based on the center position of the image data is partially cut out, as shown in FIG. In this way, the entire screen of the display unit 19 is displayed through. In this state, when focusing is performed by the AF function, a partial image centered on the focus position F at that time is cut out and displayed as shown in FIG.

  In this case, for example, marks 19a to 19d indicating the presence of an image are displayed on the top, bottom, left and right edges of the screen. By viewing these marks 19a to 19d, the user can know in which direction the undisplayed image is, and as a result, can know in which direction the cutout range can be changed.

  Here, if each direction key 15a-15d on the ring key 14 is operated like the said embodiment, the cutout range of a partial image will be changed according to these key operations, and the changed partial image will be redisplayed. . Further, if the angle adjustment keys 18a and 18b are operated, the cut-out angle is changed, and if the zoom keys 17a and 17b are operated, the cut-out size is changed, and the changed partial image is displayed again. Become.

  In the above-described embodiment, when the adjustment of the cut-out angle, position, and size of the partial image is instructed, a dedicated key corresponding to each is operated. For example, the screen of the display unit 19 is configured with a touch panel. Thus, these instruction operations may be performed by touching the screen with a pen or a finger.

  The imaging apparatus of the present invention is not limited to a digital camera. For example, any electronic device having a camera function such as a mobile phone with a camera or a PDA (Personal Digital Assistant) may be used for the technique of the present invention. Is applicable.
