  The digital camera 1 includes a CPU (Central Processing Unit) 14, a non-volatile memory 26 including an EEPROM (Electrically Erasable Programmable Lead Only Memory), and a buffer memory 22 including a RAM (Random Access Memory). Yes. The nonvolatile memory 26 stores a control program that is referred to when the CPU 14 performs various controls. The CPU 14 controls each part of the circuit by using the buffer memory 22 as a temporary storage work area in accordance with a control program stored in the nonvolatile memory 26.

  The photographing lens unit 8 includes a zoom lens 11 and a focus lens 12. Light from the subject is imaged as a subject image on the imaging surface 13 a of the imaging unit 13 made up of a CCD (Charge Coupled Device), a CMOS (Complementary Metal Oxide Semiconductor), or the like via the taking lens unit 8. The photographic lens unit 8 constitutes an optical system that projects a subject image on the imaging surface 13 a of the imaging unit 13. The imaging unit 13 constitutes an imaging unit that captures a subject image and outputs image data. The zoom lens 11 and the focus lens 12 move in the direction of the optical axis as indicated by arrows when the motors 15 and 16 are respectively driven by the control of the CPU 14 according to the operation of the zoom button 3. As the zoom lens 11 moves in the optical axis direction, the subject image formed on the imaging surface 13a by the photographing lens unit 8 is enlarged or reduced, and the magnification of the optical zoom is adjusted. In addition, when the focus lens 12 moves in the optical axis direction, the imaging state (focus) of the subject image formed on the imaging surface 13a by the photographing lens unit 8 is adjusted. The positions on the optical axis of the lenses 11 and 12 driven by the motors 15 and 16 are detected by the position detectors 17 and 18, and the position information of the lenses 11 and 12 is output to the CPU 14, respectively. The motor 16, the position detection unit 18, and the CPU 14 constitute a focus adjustment unit that adjusts the focus of the photographing lens unit 8 that forms a subject image on the imaging unit 13.

  The subject image formed on the imaging surface 13 a of the imaging unit 13 is converted into an analog imaging signal and converted into a digital signal by the A / D conversion unit 19. The image processing unit 20 acquires the imaging signal converted into a digital signal by the A / D conversion unit 19 via the bus 21 and performs image processing such as white balance processing and gamma correction on the acquired imaging signal. Then, compression processing is performed to generate image data of the captured image. Image data generated by the image processing unit 20 is stored in the buffer memory 22 by the CPU 14 and is also stored in a recording medium 24 such as a card memory that is attached to and detached from a slot (not shown) via the I / F unit 23. The

  The CPU 14 constitutes display control means, and a through image for confirming the composition of the subject image picked up by the image pickup unit 13 and a reproduced image obtained by reproducing the image data stored in the recording medium 24 are used as predetermined information. Displayed on the display element 7. When the display element 7 is accommodated in the camera body 2, that is, when part or all of the display element 7 is not pulled out from the camera body 2, the CPU 14 determines predetermined information according to the size of the display unit 6. Is displayed on the display element 7. For example, as shown in FIG. 1, the CPU 14 displays predetermined information on a part 7 a of the display surface of the display element 7 so as to be approximately the same size as the window of the display unit 6. When a part or all of the display element 7 is pulled out from the camera body 2, the CPU 14 is not housed in the display surface 7 b of the display element 7 that is pulled out from the camera body 2, that is, in the camera body 2. Predetermined information is displayed on the display element 7 according to the size of the display surface 7b of the display element 7 exposed to the outside. For example, as shown in FIG. 2, the CPU 14 causes the display element 7 to display predetermined information so as to be approximately the same size as the size of the display surface 7 b pulled out from the camera body 2.

  When the display element 7 is housed in the camera body 2, the CPU 14 causes the predetermined information to be displayed on a part 7 a of the display surface of the display element 7 so as to be approximately the same size as the window of the display unit 6. However, the present invention is not limited to this. For example, the display element 7 may display the predetermined information to be smaller than the size of the window of the display unit 6. When part or all of the display element 7 is pulled out from the camera body 2, the CPU 14 displays predetermined information on the display element 7 so as to be approximately the same size as the display surface 7 b pulled out from the camera body 2. However, the present invention is not limited to this. For example, the predetermined information may be displayed on the display element 7 so as to be smaller than the size of the display surface 7 b drawn from the camera body 2.

  The CPU 14 detects whether the display element 7 is housed in the camera body 2 or pulled out from the camera body 2 by detecting the rotation state of the winding shaft, for example, the number of rotations. When pulled out from the body 2, the display element 7 constitutes a pull-out detecting means for detecting the amount pulled out from the camera body 2. When the CPU 14 detects that the display element 7 is pulled out from the camera body 2, as shown in FIG. 2, the CPU 14 displays the predetermined information at the position of the display element 7 that can be viewed through the display unit 6. The control is switched to a state in which the display element 7 displays predetermined information on the display surface 7b drawn from the camera body 2. At this time, the CPU 14 controls to display nothing or display a specific color such as black in the area of the display element 7 that can be visually recognized by the user via the display unit 6. The CPU 14 recognizes that the display element 7 has been pulled out from the camera body 2 by detecting that the winding shaft has rotated a predetermined amount. The predetermined amount detected by the CPU 14 may be the case where the winding shaft rotates even a little compared to the case where the display element 7 is housed in the camera body 2, or the winding shaft is rotated half a turn. But you can.

  When the CPU 14 detects that the display element 7 is housed in the camera body 2 from a state in which the display element 7 is not pulled out from the camera body 2, that is, the display element 7 is pulled out from the camera body 2, Control is switched from a state in which the display element 7 displays predetermined information on the display surface 7 b drawn from the camera body 2 to a state in which the predetermined information is displayed at the position of the display element 7 that can be visually recognized through the display unit 6. May be.

  An operation unit 27 is connected to the CPU 14. The operation unit 27 includes a power button, a shutter button, a menu button, and a playback button (not shown), the zoom button 3, the rotary multi selector 4, and the enter button 5 described above. The power button is operated when turning on / off the power of the digital camera 1. The shutter button is operated when capturing a subject image. The menu button is operated when a menu screen for performing various settings of the digital camera 1 is displayed on the display element 7. The reproduction button is operated when the image data stored in the recording medium 24 is reproduced and displayed on the display element 7.

  According to the digital camera 1 of the present embodiment described above, the following effects can be obtained.

  When the display element 7 is accommodated in the camera body 2, the CPU 14 displays predetermined information on the display element 7 so that the user can visually recognize the predetermined information via the display unit 6. Thereby, the user can confirm the predetermined information without pulling out the display element 7 from the camera body 2.

  When a part or all of the display element 7 is pulled out from the camera body 2, the CPU 14 moves from the camera body 2 according to the size of the display surface 7 b pulled out from the camera body 2 in the display element 7. The predetermined information is displayed on the drawn display surface 7b. Thereby, for example, the user can visually recognize the predetermined information with a size different from the size of the predetermined information when the display element 7 is housed in the camera body 2.

  Thus, according to the digital camera 1 of the present embodiment, it is possible to perform display in accordance with the user's purpose of use and usage environment.

  Even when the display element 7 is housed in the camera body 2 or when a part or all of the display element 7 is pulled out from the camera body 2, the predetermined information can be displayed on the single display element 7. . Thereby, the number of parts can be reduced. The digital camera 1 can be reduced in size and thickness. Product cost can be reduced.

  The predetermined information that can be visually recognized by the user via the display unit 6 is that the display control means detects the display element 7 when the display detection means starts detecting the display element 7 to be pulled out from the camera body 2. The display screen is switched to the display surface 7b. Accordingly, the predetermined information is sequentially recognized as the display element 7 is pulled out from the camera body 2, and the predetermined information can be visually recognized on the display surface 7 b of the display element 7.

  A flexible display element 7 composed of an organic EL or the like was used. Thereby, since the display element 7 can be wound up or folded, the digital camera 1 can be reduced in size and thickness. Since the display element 7 is housed in the camera body 2, the shape of the camera body 2 is not limited to a conventional rectangular parallelepiped, for example, and the degree of freedom in designing the digital camera 1 is increased.

  The CPU 14 displays the subject image captured by the imaging unit 13 on the display element 7 as predetermined information. Accordingly, the user can take a picture while confirming the subject image as a through image through the display unit 6 while the display element 7 is housed in the camera body 2, or can display a reproduced image of the captured subject image. 7 can be confirmed. Shooting can be performed while confirming the subject image displayed on the drawn display element 7 as a through image, and a reproduced image of the captured subject image can be confirmed via the display unit 6.

  Note that the present embodiment can be modified as follows. In the above embodiment, when the display detecting unit detects that the display element 7 has started to be pulled out from the camera body 2, the display control unit displays the predetermined information displayed at the position corresponding to the display unit 6. Although the display is switched to the element 7, the present invention is not limited to this. For example, when it is detected that the display element 7 has been pulled out from the camera body 2 by the pull-out detection means, it is detected that the display element 7 has been pulled out from the camera body 2 as shown in FIG. At this time, the display control means may be configured to switch the predetermined information displayed at the position corresponding to the display unit 6 to the display element 7 for display. In this configuration, all of the predetermined information is visually recognized on the display surface 7b of the display element 7 in a state where the predetermined amount is pulled out from the camera body 2, and the predetermined information in the middle of the extraction is not visually recognized in an incomplete state. Tesumu.

  As shown in FIG. 4, when the display detecting unit 7 detects that the display element 7 has been pulled out to a length B that is, for example, half of the length A from which the display element 7 has been most pulled out, The predetermined information displayed at the position corresponding to 6 may be switched to the display element 7 and displayed. 4 that are the same as those in FIG. 2 are assigned the same reference numerals, and descriptions thereof are omitted. In such a case, the display direction of the predetermined information may be changed by the display control of the CPU 14 in accordance with the shape of the display surface 7 b of the display unit 6 or the display element 7. As shown in FIG. 4, when the display element 7 is pulled out from the camera body 2 by a length B, the CPU 14 displays the display direction of the predetermined information horizontally like a subject image drawn by a dotted line. In the case where the shape of the display unit 6 is not a horizontally long rectangular shape as shown in the figure but a vertically long rectangular shape, similarly, predetermined information is displayed on a part 7 a of the display surface displayed at a position corresponding to the display unit 6. Display horizontally. According to this configuration, since the display direction of the predetermined information can be changed by the CPU 14 according to the shape of the display surface of the display unit 6 or the display element 7, the use range of the display surface of the display unit 6 or the display element 7 is maximized. The predetermined information can be displayed in a large size by widening.

  In the above embodiment, when the display of the predetermined information is switched from the display surface of the positional relationship corresponding to the display unit 6 to the display surface where the display element 7 is pulled out from the camera body 2, the CPU 14 hides the display unit 6. Although it is configured to perform control, it is not limited to this. For example, in a state where the predetermined information is displayed on the display surface of the display element 7 pulled out from the camera body 2 by the CPU 14, other predetermined information different from the predetermined information displayed on the display element 7 is displayed via the display unit 6. You may make it the structure displayed on the display surface of the display element 7 which a user can visually recognize. For example, photographing information such as shutter speed, ISO (International Organization for Standardization) sensitivity, white balance, and number of remaining frames, which is different from a through image and a reproduced image displayed on the display element 7 as predetermined information, The image is displayed on the display surface of the display element 7 that can be visually recognized by the user via the display unit 6. In this configuration, the user can acquire more information via the display element 7 and the display unit 6.

  In the above embodiment, the case where the organic EL is used as the flexible material constituting the display element 7 has been described. However, the present invention is not limited to this. For example, a flexible material such as electronic paper or a film type LCD (Liquid Crystal Display) may be used as the display element 7. Even in this configuration, the same effects as the above-described embodiment are achieved.

  In the said embodiment, although the display element 7 was set as the structure which has a rectangular shape, it is not restricted to this. For example, as shown in FIG. 5, the region of the display element 7 that is located inside the camera body 2 and is not visible from the display unit 6 may be cut out. In FIG. 5, the same parts as those in FIG. According to this configuration, the product cost can be reduced by reducing the display surface of the display elements 7 that are not used.

  In the above embodiment, the CPU 14 displays predetermined information according to the size of a part 7 a of the display surface of the display element 7 observed from the display unit 6 in a state where the display element 7 is housed in the camera body 2. However, the present invention is not limited to this. For example, as shown in FIG. 6, the display unit 6 is configured with a display element 31 that is separate from the display element 7 on the back surface of the window that configures the display unit 6, and is separated from the display element 7 under the control of the CPU 14. The display element 31 may be configured to display predetermined information. In FIG. 6, the same parts as those in FIG. According to this configuration, since the display element 31 can display predetermined information without driving the display element 7 when the display element 7 is housed in the camera body 2, the display surface of the display element 7 can be displayed. It is not necessary to drive the display element 7 in order to display the predetermined information on the part 7a.

  In the above embodiment, the camera body 2 is provided with one display unit 6, but the present invention is not limited to this. For example, as shown in FIG. 7, the camera body 2 may be provided with a plurality of display units 6 and 6 ′. In FIG. 7, the same parts as those in FIG. In this configuration, for example, predetermined information is displayed on one display unit 6, and other predetermined information is displayed on the other display unit 6 ′, so that the display element 7 can be used even when it is housed in the camera body 2. The person can acquire more information via each display part 6 and 6 '.

  In the said embodiment and each modification, although it was set as the structure using the display element 7 which consists of a flexible material, this invention is not limited to this. For example, a plate-like display element that does not have flexibility may be configured to be slidable with respect to the main body and configured to be housed in the main body.

  In the above embodiment and each modification, the digital camera has been described as an example, but the present invention is not limited to this. For example, the present invention may be applied to a display device such as a viewer such as a digital photo frame that does not include a photographing lens unit or an imaging unit and that simply displays a photographed image. Even with each of these configurations, the same operations and effects as those of the above-described embodiment and the respective modified examples are exhibited.
