Recording and reproduction are performed, and the control is performed by the CPU 209.

  The role of the CPU 209 in the memory control system is to capture the image signal compressed by the JPEG / MPEG processing unit 206 via the memory controller 207 and write the image signal as a file to the memory card 211 using the card I / F 210. . Further, the image signal file written in the memory card 211 is read out using the card I / F 210 and sent out to the JPEG / MPEG processing unit 206 via the memory controller 207. The CPU 209 executes these processes using application programs stored in the memory 212. The memory 212 includes a ROM (Read Only Memory) in which these programs and data are stored, a RAM (Random Access Memory) as a work memory, and a non-volatile memory in which setting data of the apparatus 100 is stored.

It is also possible to display on the second LCD 104.

  The video decoder 215 and the graphic controller 216 are also supplied with the OSD signal generated by the OSD (On Screen Display) 217. The OSD 217 generates and outputs an OSD signal for constructing a GUI (Graphical User Interface) format image based on data such as characters and symbols stored in the memory 212 under the control of the CPU 209 via the memory controller 207, for example. To do. The OSD signal is, for example, a menu image signal for setting the device 100 or an image signal for displaying the operation state of the device 100, or a cursor for the user to select a selection item, for example. There is.

  Finally, in addition to the CPU 209 and the memory 212, the system control system includes the shutter button 106, the ten sentence button 107 shown in FIG. 1, the mode switching button 108 for switching the recording mode to the still image mode or the moving image mode, and the recorded still image or moving image. An operation input unit 105 including a playback button 109, a zoom adjustment button 110, and the like, a touch panel I / F 218, and an input unit 219. The touch panel I / F 218 changes the second LCD 104 of the photographing apparatus main body 101 to a function having a touch panel function under the control of the CPU 209, and the input unit 219 becomes the surface of the second LCD 104 itself. .

  The operation of the image capturing apparatus 100 configured as described above will be described. In a normal still image shooting operation, first, the still image recording mode is set by the operation switching button 105c of the operation input unit 105.

  Next, the display unit 102 shown in FIG. 1 is rotated 180 degrees in the A and B directions, and the lens 114 is directed toward the subject. As a result, an image formed on the CCD photographing element 202 via the optical system 201 is read out as an image signal and converted into a digital signal by the A / D conversion unit 203. Further, processing using the work memory 208 and the memory controller 207 is performed by the signal processing unit 205, and thereafter, the signal is taken into the video decoder 215 from the memory controller 207.

  The video decoder 215 converts the signal into a signal for display on the LCD, and supplies the signal to the first LCD 111 via the LCD driver 213 for display.

  The user determines the composition of shooting based on the image displayed on the first LCD 111 and operates the shutter button 105 a of the operation input unit 105. As a result, the CPU 209 makes full use of the CCD drive unit 204 to once clear the charge of the CCD, then sequentially reads out the charge corresponding to one newly accumulated screen and converts it into a digital signal by the A / D conversion unit 203. After that, the data is stored in the work memory 208 via the signal processing unit 205 and the memory controller 207.

  The signal processing unit 205 performs white balance correction, gamma correction, interpolation processing, and the like on the image signal stored in the work memory 208 via the memory controller 207 and stores the image signal in the work memory 208 again.

  The image signal stored in the work memory 208 is read out by the memory controller 207 and taken into the JPEG / MPEG processing unit 206, where compression processing based on the JPEG standard is performed.

  At the same time, the CPU 209 stores the image signal compressed by the JPEG / MPEG processing unit 206 as a file in the memory card 211 using the card I / F 210. Thus, the still image shooting process is completed. At this time, the still image is recorded with a file name according to DCF, and attribute data (date and time, serial number, etc.) according to Exif is recorded together.

  When the still image photographing process is completed, the image signal output from the CCD photographing element 202 is converted again into a digital signal by the A / D conversion unit 203, sequentially stored in the work memory 208, and subjected to predetermined processing. The image is displayed on the first LCD 111 via the video decoder 215 and the LCD driver 213 to prepare for the next shooting.

  When the captured image signal is displayed and checked, if the playback button 105d of the operation input unit 105 is operated, the CPU 209 makes full use of the OSD 217 to display the file list of the image signal stored in the memory card 211. Then, it is generated as a display signal together with the attribute data recorded together, sent to the graphic controller 216, and displayed on the second LCD 104 via the LCD driver 214.

  The user uses the cross button 105b of the operation input unit 105 to select an image to be reproduced from the displayed list. Thereby, the CPU 209 reads out the image signal from the memory card 211, performs decompression processing by the JPEG / MPEG processing unit 206, and stores it in the work memory 208 as an uncompressed image signal.

  Further, the image signal stored in the work memory 208 is read out via the memory controller 207, sent to the video decoder 215, and displayed on the first LCD 111 via the LCD driver 213.

  When a moving image is recorded, the moving image recording mode is set by the operation mode switching button 105c of the operation input unit 105, the display unit 102 is moved as necessary, the optical system lens 116 is directed toward the subject, and the shutter is moved. Press the button 105a.

  As a result, the image signal from the CCD imaging device 202 is stored in the work memory 208 via the A / D conversion unit 203 and from the signal processing unit 205 via the memory controller 207. The image signal stored in the memory 208 is converted into a sufficient resolution as a moving image by reducing the resolution in addition to processing equivalent to still image shooting such as white balance adjustment.

  The JPEG / MPEG processing unit 206 uses the work memory 208 via the memory controller 207 to compress the image signal processed by the signal processing unit 205 based on the MPEG standard. The CPU 209 writes the compressed image signal as a file in the memory card 211 via the card I / F 210. In the recording of the moving image, for example, date / time / date / time data taken is written as attribute data. For this purpose, the CPU 209 has a clock function inside.

  The moving image recording process is continuously performed until the shutter button 105a of the operation input unit 105 is operated again, and a moving image signal file compressed thereby is written to the memory card 211. is there.

  When playing back a moving image written in the memory card 211, when the playback button 105 d of the operation input unit 105 is operated, the CPU 209 reads a list of moving image files recorded from the memory card 211, and stores it in the card I. / F210 is taken in, and the display list is generated using the OSD 217. Further, the CPU 209 sends the generated list to the graphic controller 216, for example, and displays it on the second LCD 104 via the LCD driver 214.

  The user uses the cross button 105b of the operation input unit 105 to select an image to be reproduced from the displayed list. As a result, the CPU 209 reads out the image signal from the memory card 211, uses the work memory 208 and the memory controller 207 to perform decompression processing in the JPEG / MPEG processing unit 206, and outputs it to the video decoder 215 as an uncompressed moving image signal. Derived and displayed on the first LCD 113 via the LCD driver 213.

  As described above, recording and reproduction of still images and recording and reproduction of moving images can be performed. However, the present invention further realizes various functions by effectively using the second LCD 104. The embodiment will be described in detail below.

  FIG. 3 is a block diagram for explaining an embodiment of the photographing apparatus 100 of the present invention. In this embodiment, the image is recorded on the memory card 211 on the second LCD 104 of the image photographing apparatus main body 101. A thumbnail image of a still image is displayed, and an image selected from the thumbnail images is displayed on the LCD 111 of the display unit 102. In FIG. 3, the same components as those in FIG.

  That is, when the user tries to reproduce a still image, the operation mode switching button 105c of the operation input unit 105 of the photographing apparatus main body 101 is operated to switch to the still image mode, and then the reproduction button 105d is operated.

  Thereby, the CPU 209 reads the thumbnail image signal from the memory card 211 and sends it to the graphic controller 216 via the memory controller 207. The graphic controller 216 constructs a thumbnail image for display and displays it on the second LCD 104 via the LCD driver 214.

  At this time, the CPU 209 simultaneously uses the OSD 217 to generate a cursor signal, supply it to the graphic controller 216, and superimpose it on the thumbnail image. Thereby, the user can select a desired image with the cursor from the displayed thumbnail images.

  In FIG. 3, the hatched portion is a cursor 301, which can be moved in the vertical direction and the horizontal direction by the cross button 105b. A still image 303 corresponding to the thumbnail image 302 surrounded by the cursor 301 is displayed on the first LCD 111.

  That is, the CPU 209 reads a file corresponding to the thumbnail image on which the cursor 301 is located from the memory card 211, decompresses it with the JPEG / MPEG processing unit 206 using the memory controller 207 and the work memory 208, and outputs the video as an uncompressed image signal. Derived to the decoder 215. The video decoder 215 performs processing for display, and displays it on the first LCD 111 via the LCD driver 213.

  As described above, in the embodiment shown in FIG. 3, the thumbnail image and the image selected from the thumbnail image are displayed on different LCDs, so that the user can display the still image written in the memory card 211. Since the still image selected from the image can be displayed in a large size, the operability can be improved.

  In the embodiment of FIG. 4, a still image written in the memory card 211 is displayed on the LCD 104 of the photographing apparatus main body 101, and an enlarged image of the still image displayed on the LCD 104 is displayed on the LCD 111 of the display unit 102. ing.

  In FIG. 4, a still image 401 read from the memory card 211 is displayed on the second LCD 104. At this time, in the photographing apparatus main body 101, the uncompressed image signal read from the memory card 211, decompressed by the JPEG / MPEG processing unit 206, and restored is stored in the work memory 208. The displayed image 401 is continuously read from the image 401 and processed by the graphic controller 216.

  In such a state, when the zoom button 105e of the operation input unit 105 is operated, the CPU 209 makes full use of the OSD 217 via the memory controller 207 to construct a frame displayed on the screen of the second LCD 104. It is sent to the graphic controller 216 and superimposed on the still image 401 read from the work memory 208. Thereby, a zoom display frame 402 is displayed in the image 401 displayed on the second LCD 104.

  At the same time, the CPU 209 makes full use of the memory controller 207 to display the portion (inside the frame) selected in the zoom display frame 402 of the image signal stored in the work memory 208 on the entire screen of the first LCD 111. The image is enlarged and sent to the video decoder 215, and is displayed as an image 403 on the first LCD 111 via the LCD driver 213.

  The zoom button 105e of the operation input unit 105 is a so-called seesaw type operation button. When the zoom button 105e is continuously pressed in one direction, the zoom display frame 402 is enlarged, and the enlargement ratio of the still image displayed on the first LCD 111 is reduced. If the button is continuously pressed to the opposite side, the zoom display frame 402 becomes smaller and the enlargement ratio becomes larger.

  As described above, in the embodiment shown in FIG. 4, the zoom display frame 402 is displayed on the image displayed on the LCD 104 of the image capturing apparatus main body 101, so that the range selected by the frame is displayed. Since the enlarged image is displayed on the LCD 111 of the display unit 102, the operability can be further improved.

  Furthermore, another embodiment is shown in FIG. In FIG. 5, the still image 501 reproduced from the memory card 211 is displayed on the LCD 104 of the photographing apparatus main body 101, and the image 502 photographed by the CCD image sensor 202 is displayed on the LCD 111 of the display unit 102. It is configured. Alternatively, the still image 501 is displayed on the LCD 104 of the photographing apparatus main body 101, and the moving image 502 read from the memory card 211 is displayed on the LCD 111 of the display unit 102.

  For example, when the two-screen button 105g of the operation input unit 105 is operated from the still image display state shown in FIG. 3, the image that has been displayed on the LCD 111 of the display unit 102 until then is displayed as shown in FIG. Is displayed as an image 501 on the LCD 104, and an image 502 captured by the CCD image sensor 202 is displayed on the LCD 111 of the display unit 102.

  That is, when the two-screen button 105g is operated, the CPU 209 reads the still image signal that has been read from the work memory 208 and displayed on the first LCD 111 until then from the graphic controller 216 via the LCD driver 214. Switching to display on the second LCD 104. Further, the image signal captured by the CCD image sensor 202 is sent to the video decoder 215 via the A / D converter 203, the signal processor 205, and the memory controller 207, and displayed on the first LCD 111 via the LCD driver 213. .

  When the two-screen button 105g is further operated from the state shown in FIG. 5, for example, the moving image 601 read from the memory card 211 is displayed on the LCD 111 of the display unit 102 as shown in FIG. . The moving image displayed at this time is, for example, the most recently written moving image written in the memory card 211. Further, a still image 602 similar to that in FIG. 5 is displayed on the LCD 104 of the photographing apparatus main body 101.

  When the two-screen button 105g is operated from the state of FIG. 5, the CPU 209 reads the latest moving image from the memory card 211 and decompresses it with the JPEG / MPEG processing unit 206 using the work memory 208 and the memory controller 207. Processing is performed, the image is sent to the video decoder 216, and displayed on the first LCD 111 via the LCD driver 213.

  The display form by the two-screen button 105g described above is not limited to that shown in FIGS. 5 and 6, and each image may be displayed on any LCD.

  According to the embodiment shown in FIG. 5 and FIG. 6, since the two LCDs 104 and 111 are used independently, various display modes can be performed. For example, a moving image can be displayed on one LCD 111, and a still image related to the moving image can be displayed on the other LCD 104. Further, the still image may be sequentially switched according to the moving image scene. In this case, when writing to the memory card 211, each file is recorded in association with the attribute, and when reading, it is specified based on the attribute.
