Although the finder 50 is configured by an electronic view finder, an embodiment in which the finder 50 is replaced with an optical finder is also possible.

  The monitor 69 is a display means that can be used as an electronic viewfinder for checking the angle of view at the time of shooting, and displays a preview image of the shot image, a reproduced image read from an external recording device such as a memory card, and the like. Further, the monitor 69 can display information such as the number of shootable images (number of frames) and playback frame number, macro mode display, recording image quality (quality) display, and pixel number display. The photographer can adjust the angle of view by looking at the video (through image) displayed on the finder 50 or the monitor 69. The monitor 69 is composed of a flexible display device such as an organic EL display (organic electroluminescence display), and has a long shape.

  FIG. 2 is an external perspective view of the camera 10 in a state where the lens unit 14 is housed in the main body 11. The lens unit 14 is retracted and housed in the main body 11 in response to the power switch 82 being turned off. When the power switch 82 is turned off, the flexible monitor 69 is moved from the slit 11a opened in the main body 11 into the main body 11 by a take-up / feeding mechanism 15 described later provided in the main body 11. It is wound and stored. In this way, the lens unit 14 and the monitor 69 are housed in the main body 11 in accordance with the power switch 82 being turned off, and the lens unit 14 and the monitor 69 are protected.

  When the power switch 82 is switched from OFF to ON, the monitor 69 is drawn out from the slit 11a that is the opening of the main body 11 from the housed state. The drawn-out monitor slides on the monitor guide 11b which is a groove formed on the side surface of the concave flat monitor mounting portion 63 provided on the surface of the main body 11, and the image display surface F is exposed ( (See FIG. 1). When the power switch 82 is switched from OFF to ON, the lens unit 14 also projects from the main body 11.

  FIG. 3 is a perspective view of the winding / feeding mechanism 15. The winding / feeding mechanism 15 has a width substantially the same as the width of the long monitor 69, and projecting convex portions 15 a are provided on the surface of the end portions thereof at substantially equal intervals L along the circumferential direction. Sprocket. A drive gear 15c is attached to a rotary shaft 15b that passes through the center of the cylinder of the winding / feeding mechanism 15, and a gear of the power transmission mechanism 142 (not shown) and the drive gear 15c are meshed with each other to rotate from the motor 122. As a result, the rotating shaft 15b rotates to take up / feed out the monitor 69.

  FIG. 4 is a perspective view of the monitor 69. A reader 68 is attached to one end BD of the monitor 69. The rigidity of the reader 68 is higher than that of the monitor 69, and the monitor 69 is wound or unwound when the rotational force of the winding / feeding mechanism 15 is transmitted to the monitor 69 via the reader 68. The length of the reader 68 corresponds to the outer peripheral length of the winding / feeding mechanism 15 and prevents the monitor 69 from coming into direct contact with the winding / feeding mechanism 15 and being damaged.

  At both ends of the monitor 69 and the reader 68 along the long axis direction, a narrow band-like support body 67 is provided. In the first portion 67-1 where the support 67 is adhered to the reader 68, hole-shaped concave portions 67 a are provided at substantially equal intervals L. The second portion 67-2 on which the support 67 is adhered to the monitor 69 is not provided with a convex portion or the like, but may be provided if it is particularly necessary for winding / unwinding the monitor 69.

  FIG. 5 is a cross-sectional view of the support 67. A wire 60 is inserted into the support 67, and the tip E of the wire 60 is fixed to the tip of the support 67. A tension is applied to the wire 60 in a direction Y2 opposite to the feeding direction Y1 of the monitor 69, and the bending of the monitor 69 is removed. The tension in the direction Y2 is smaller than the feeding force of the monitor 69 in the direction Y1, and the wire 60 is also fed out according to the feeding of the monitor 69 in the direction Y1. The feeding of the monitor 69 does not stop due to the tension of the wire 60.

  FIG. 6 is a perspective view showing a state in which the monitor 69 is wound around the winding / feeding mechanism 15. When the winding / feeding mechanism 15 rotates in the X1 direction in the drawing, the winding force is transmitted to the reader 68 by fitting the convex portion 15a of the winding / feeding mechanism 15 into the concave portion 67a of the support 67, and the monitor 69 is wound. The take-up / feeding mechanism 15 is wound up. On the other hand, when the take-up / feeding mechanism 15 rotates in the X2 direction in the drawing, the reader 68 and the monitor 69 wound around the take-up / feeding mechanism 15 are loosened. When the take-up / feeding mechanism 15 further rotates in the X2 direction shown in the figure, a rotational output is applied to the monitor 69 in the Y1 direction by the rotational moment generated by the rigidity of the support 67, and the monitor 69 is extended in the Y direction shown in the figure.

  FIG. 7 is a cross-sectional view taken along A1-A2 of the digital camera 10 of FIG. Inside the camera body 11, a take-up / feed-out mechanism 15 that winds / feeds out the monitor 69 is provided. By the rotation of the take-up / feed-out mechanism 15 in the X2 direction, the monitor 69 is attached to the rear surface of the camera body 11. It is drawn out in the Y1 direction or wound up and stored in the camera body 11 by rotation in the X1 direction. The wire 60 inserted through the support 67 is wound by the wire winding mechanism 61, whereby tension is applied in the direction Y2 opposite to the feeding direction Y1 of the monitor 69. Thereby, the curl generated by the winding of the monitor 69 is removed, and the bent monitor 69 can be prevented from coming into contact with the main body 11 and being damaged.

  Further, as shown in FIG. 8, the front end E of the monitor 69 fed out from the slit 11a is guided downward above the slit 11a so that the front end 69E of the monitor 69 is correctly hung out from the camera body 11 and fed out. A guide member 62 may be provided.

  FIG. 9 is a functional block diagram of the digital camera 10. In the figure, a central processing unit (CPU) 112 includes a shutter button 80, a power switch 82, a mode switch 84, an aspect ratio switch 85, a cross key, a menu / execution button, a cancel / return button, a display button, and a shift. Based on input from the operation unit 157 including buttons, display switching buttons, enlarged display buttons, and an AE fixed button for inputting an AE lock instruction, the respective circuits in the digital camera 10 are comprehensively controlled.

  The camera 10 includes a communication unit 156 that performs wired or wireless connection with various communication means such as a network such as the Internet or a USB port, and transmits and receives various data such as images and programs.

  Now, when the shooting mode is set by the mode switch 84, the CPU 112 displays a moving image (through image) on the monitor 69 so that the shooting angle of view can be confirmed. That is, the subject light that has passed through the lens unit 14 forms an image on the light receiving surface of the image sensor (CCD) 127. The CCD 127 converts the subject light imaged on the light receiving surface into a signal charge in an amount corresponding to the light amount. The signal charge accumulated in this way is sequentially read out as a voltage signal (image signal) corresponding to the signal charge based on a drive pulse supplied from the timing generator 121 in accordance with a command from the CPU 112.

  A signal output from the CCD 127 is sent to an analog processing unit (CDS / AMP) 123, where R, G, B signals for each pixel are sampled and held (correlated double sampling processing), amplified, and then A / Applied to the D converter 124. The dot sequential R, G, B signals converted into digital signals by the A / D converter 124 are stored in a memory (SDRAM) 128 via the image input controller 126. The memory 128 is used as a temporary storage area for image data, as well as a program development area and a calculation work area for the CPU 112.

  The image signal processing circuit 130 processes the R, G, and B signals stored in the memory 128 according to a command from the CPU 112. That is, the image signal processing circuit 130 includes a synchronization circuit (a processing circuit that interpolates a spatial shift of the color signal associated with the color filter array of the single CCD and converts the color signal into a simultaneous expression), a white balance correction circuit, It functions as an image processing means including a gamma correction circuit, a contour correction circuit, a luminance / color difference signal generation circuit, etc., and performs predetermined signal processing using the memory 128 in accordance with commands from the CPU 112.

  The R, G, and B signals input to the image signal processing circuit 130 are converted into luminance signals (Y signals) and color difference signals (Cr, Cb signals) and subjected to predetermined processing such as gamma correction. The YC signal processed by the image signal processing circuit 130 is stored in the VRAM 132.

  When the captured image is output to the monitor 69, the YC signal is read from the VRAM 132 and sent to the video encoder 134. The video encoder 134 converts the input YC signal into a predetermined display signal (for example, an NTSC color composite video signal) and outputs the converted signal to the monitor 69.

  The YC signal of each frame processed at a predetermined frame rate is alternately written in the A area and B area of the VRAM 132, and the Y area other than the area where the YC signal is written out of the A area and B area of the VRAM 132. The YC signal that has been written is read out from this area. In this way, the YC signal in the VRAM 132 is periodically rewritten, and a video signal generated from the YC signal is supplied to the monitor 69, whereby the image being captured is displayed on the monitor 69 in real time. The user can confirm the shooting angle of view from the video (through) displayed on the monitor 69.

  When the zoom up operation is performed with the up key of the cross key or the zoom down operation is performed with the down key, the CPU 112 controls the motor driver 120 and drives the motor 122 according to the operation. A DC motor is used as the motor 122, and the zoom lens 12 is driven in the tele direction or the wide direction by changing the polarity of the voltage applied from the motor driver 120 to the motor 122. The rotational power of the motor 122 is transmitted to the lens unit 14 via the power transmission mechanism 142, and the lens unit 14 is retracted into or out of the camera body 11, so that the zoom lens 12 is telescopically moved. Alternatively, the focal length is changed by moving in the wide direction.

  Here, when the shutter button 80 is half-pressed, the AE and AF processes are started. That is, the image signal output from the CCD 127 is input to the AF detection circuit 136 and the AE / AWB detection circuit 138 via the image input controller 126 after A / D conversion.

  The AE / AWB detection circuit 138 includes a circuit that divides one screen into a plurality of areas (for example, 16 × 16) and integrates RGB signals for each divided area, and provides the integrated value to the CPU 112. The CPU 112 detects the brightness of the subject (subject brightness) based on the integrated value obtained from the AE / AWB detection circuit 138, and calculates an exposure value (shooting EV value) suitable for shooting. A diaphragm value and shutter speed are determined according to the obtained exposure value and a predetermined program diagram, and the CPU 112 controls the electronic shutter of the CCD 127 via the timing generator 121 according to the determined exposure value and a power transmission mechanism for transmitting the power of the motor 122. The diaphragm 116 is controlled via 142 to obtain an appropriate exposure amount.

  In addition, the AE / AWB detection circuit 138 calculates an average integrated value for each color of the RGB signals for each divided area during automatic white balance adjustment, and provides the calculation result to the CPU 112. The CPU 112 obtains an integrated value of R, an integrated value of B, and an integrated value of G, obtains a ratio of R / G and B / G for each divided area, and calculates R / G and R / G of the values of B / G. The light source type is determined based on the distribution in the color space of G, B / G, etc., and, for example, the value of each ratio is about 1 (that is, RGB in one screen) according to the white balance adjustment value suitable for the determined light source type. The gain value (white balance correction value) for the R, G, B signals of the white balance adjustment circuit is controlled so that the integration ratio of R: G: B≈1: 1: 1) Apply correction.

  In contrast, for example, contrast AF in which the imaging lens 118 of the lens unit 14 is moved so that the high-frequency component of the G signal of the image signal is maximized is applied to the AF control. That is, the AF detection circuit 136 has a high-pass filter that passes only a high-frequency component of the G signal, an absolute value processing unit, and a focus area set in advance in the display screen of the monitor 69 (for example, the center of the screen). An AF area extracting unit that cuts out a signal and an integrating unit that integrates absolute value data in the AF area are configured.

  The integrated value data obtained by the AF detection circuit 136 is notified to the CPU 112. The CPU 112 calculates a focus evaluation value (AF evaluation value) at a plurality of AF detection points while controlling the motor driver 120 and the power transmission mechanism 142 to move the photographing lens 118, and determines a lens position where the evaluation value is maximized. Determined as the in-focus position. Then, the motor driver 142 is controlled so as to move the photographing lens to the obtained in-focus position. The calculation of the AF evaluation value is not limited to a mode using the G signal, and a luminance signal (Y signal) may be used.

  The AE / AF process is performed, and when the shutter button 80 is fully pressed, the recording photographing operation starts. The image data acquired in response to S2 ON is converted into a luminance / color difference signal (Y / C signal) in the image signal processing circuit 130, subjected to predetermined processing such as gamma correction, and then stored in the memory 128. The

  The Y / C signal stored in the memory 128 is compressed in accordance with a predetermined format by the compression / decompression processing circuit 144 and then recorded as an Exif (Exchangeable Image File Format) file on the recording medium 40 via the media controller 146. The image is recorded in the data portion of the Exif file, and incidental information such as shooting conditions is recorded in a tag provided in the header portion of the Exif file.

  The camera 10 is provided with an aspect ratio changeover switch 85, and can switch between the normal shooting mode and the panoramic shooting mode while waiting for the shutter button 80 to be fully pressed. When the normal shooting mode is switched by the aspect ratio switch 85 and the shutter button 80 is fully pressed, a full-size image (aspect ratio 1.5) is recorded. On the other hand, when the panorama shooting mode is switched by the aspect ratio switch 85 and the shutter button 80 is fully pressed, a panorama size image (aspect ratio 3.0) in which a predetermined portion above and below the full size image is shielded is recorded. To do. The aspect ratio that can be switched between by the aspect ratio switch 85 is not limited to the full size or panorama size as described above, but may be other aspect ratios.

  When the playback mode is selected by the mode switch 84, the compressed data of the last image file (last recorded file) recorded on the recording medium 40 is read. When the file related to the last recording is a still image file, the read image compressed data is decompressed into an uncompressed YC signal via the compression / decompression processing circuit 144 and stored in the VRAM 132. The YC signal stored in the VRAM 132 is added to the video encoder 134. The video encoder 134 creates an NTSC color composite video signal from the input YC signal and outputs it to the monitor 69. As a result, the frame image of the last frame recorded on the recording medium 40 is displayed on the monitor 69.

  Thereafter, when a forward frame advance switch (not shown) is pressed, the frame is advanced in the forward direction, and when a reverse frame advance switch (not shown) is pressed, the frame is advanced in the reverse direction. Then, the frame-positioned image file at the frame position is read from the recording medium 40, and the frame image is reproduced on the monitor 69 in the same manner as described above. When the frame of the last frame is displayed and the frame is advanced in the forward direction, the first frame image file recorded on the recording medium 40 is read and the first frame image is monitored. 69 is played back.

  The main power supply 164 supplies power to each part of the camera 10. The remaining capacity detection unit 165 detects the remaining capacity by measuring the power supply voltage of the main power supply 164 and switches the power supply to the backup power supply 166 when the remaining capacity of the main power supply 164 falls below a predetermined threshold. The backup power supply 166 does not supply power to a high load such as a strobe, but supplies power to the CPU 112, SRAM 167, etc., which operate with low power consumption, and backs up necessary information.

  The rotational power of the motor 122 is also transmitted to the winding / feeding mechanism 15 and the wire winding mechanism 61 via the power transmission mechanism 142. The feed amount of the monitor 69 to the outside of the main body 11 by the take-up / feed mechanism 15 is determined by the CPU 112, and the CPU 112 controls the motor driver 120 and the power transmission mechanism 142, and only the determined feed amount (hereinafter referred to as the target feed amount). The winding / feeding mechanism 15 rotates the motor 122 so that the monitor 69 is fed out of the main body 11.

  In addition, the wire winding mechanism 61 may not be wound by the power from the power transmission mechanism 142 but may be provided with a mechanism for winding the wire winding mechanism 61 itself by a self force such as a spring.

  In the configuration of FIG. 9, the power of the motor 122 is transmitted to the winding / feeding mechanism 15, the lens unit 14, or the aperture 116 via the power transmission mechanism 142, but the winding / feeding mechanism 15 and the lens unit 14 are transmitted. Alternatively, the power for driving the diaphragm 116 may be separate. For example, as shown in FIG. 10, power for driving the take-up / feeding mechanism 15 is supplied from the motor 122a via the power transmission mechanism 142a, and power for driving the lens unit 14 or the aperture 116 is transmitted from the motor 122b. The motor 122a and the motor 122b may be driven independently by the motor drivers 120a and 120b, respectively.

  However, in the configuration of FIG. 10, it is necessary to provide the motor 122a for driving the take-up / feeding mechanism 15 and the motor 122b for driving the lens unit 14, respectively, so that transmission / release mechanisms 142-1 and 142-2 are provided. There is a possibility that the cost may be increased as compared with the configuration of FIG. 9 in which the configuration of FIG. 9 is provided, and the configuration of FIG.

  Although not shown, a disc-shaped rotary encoder with a monochrome pattern attached thereto is attached to the rotating shaft 122a of the motor 122. The CPU 112 calculates the total rotation angle of the rotary shaft 122a by detecting the change of the black and white pattern of the rotary encoder due to the rotation of the motor 122 by a photo interrupter (not shown), and based on this, the current feed amount of the monitor 69 (hereinafter, the current feed amount). Calculated).

  The target feed amount of the CPU 112 is stored in the EEPROM 133. Preferably, the first target extension amount corresponding to the photographing mode set by the mode switch 84 or the second target extension amount corresponding to the reproduction mode is stored.

  When the photographing mode is set from the mode changeover switch 84, the CPU 112 controls the motor driver 120 to rotate the motor 122 so that the take-up / feeding mechanism 15 extends the monitor 69 by the first target feed amount. The first target feed amount is an area of the monitor 69 suitable for displaying a through image.

  When the playback mode is set by the mode changeover switch 84, the CPU 112 controls the motor driver 120 so that the winding / feeding mechanism 15 rotates the motor 122 so that the monitor 69 extends the second target feed amount. The second target feed amount is an area of the monitor 69 suitable for displaying a photographed image and its reduced image (thumbnail image).

  Preferably, a target feed amount corresponding to the aspect ratio of the image set by the aspect ratio changeover switch 85 is stored in the EEPROM 133. The target feeding amount corresponding to the aspect ratio 1.5 in the normal shooting mode is that the aspect ratio of the monitor 69 exposed outside the main body 11 is 1: 1.5. On the other hand, the target feed amount corresponding to the aspect ratio 3.0 in the panoramic shooting mode is that the aspect ratio of the monitor 69 exposed outside the main body 11 is 1: 3.0. When the normal shooting mode or the panoramic shooting mode is set by the aspect ratio switch 85, the aspect ratio of the monitor 69 is extended to match the aspect ratio of the set shooting mode. For this reason, a through image can be projected on the entire monitor 69.

  When the power switch 82 is turned on, the CPU 112 may rotationally drive the motor 122 so that the winding / feeding mechanism 15 feeds the monitor 69 by a default target feed amount stored in the EEPROM 133 in advance.

  When the power switch 82 is turned on, the lens unit 14 also performs the operation of projecting the camera body 11, but either the projecting of the lens unit 14 or the extension of the monitor 69 may be performed first.

  Further, when the power switch 82 is turned off, the lens part 14 is retracted and the monitor 69 is wound, but either the lens part 14 is retracted or the monitor 69 is wound first. The wire winding mechanism 61 winds the wire 60 in accordance with the winding of the monitor 69.

Is provided. The support plate 14 is restricted from moving in the Y2 direction by contacting the concave plane. The position where the support plate 14 contacts the concave plane is called the initial position. The sliding force of the support plate 14 is given by a rack and pinion mechanism that is mechanically interlocked with the rotation of the take-up / feeding mechanism 15. When the take-up / feeding mechanism 15 rotates in the direction X2, the support plate 14 moves in the direction Y1. When the winding / feeding mechanism 15 rotates in the direction X1, the support plate 14 moves in the direction Y2.

  As shown in FIG. 16, the engaging claw 69a of the monitor 69 is not inserted into the engaging portion 14c until the monitor 69 covers the entire monitor guide mounting portion 69b.

  As shown in FIG. 17, when the monitor 69 is extended to a position where the engaging claw 69a and the engaging portion 14c are engaged, as shown in FIGS. 18 and 19, the convex movement restricting portion 11c provided in the main body 11 is provided. The support plate 14 is extended in the direction Y1. The support plate 14 does not leave the concave plane of the monitor guide mounting portion 69b. Since the engaging claw 69a and the engaging portion 14c are engaged with each other, the monitor 69 is extended in the direction Y1 in conjunction with the extension of the support plate 14, and the monitor 69 is slackened or bent by the tension applied to the engaging claw 69a. Is removed.

  On the other hand, as shown in FIG. 20, when the monitor 69 is wound in the direction Y2, the support plate 14 moves in the direction Y2 in conjunction with the winding and returns to the initial position. When the monitor 69 is further wound in the direction Y2 with the support plate 14 returned to the initial position, the engaging claw 69a comes into contact with the concave portion 14e, so that the concave portion 14e is lifted upward, and the opening is enlarged. The engagement between 69a and the recess 14e is released. As a result, the monitor 69 can be further wound in the direction Y2.

<Third Embodiment>
A support for removing the deflection of the monitor 69 may be attached to the monitor 69. For example, as shown in FIG. 21, a thin plate-like second support body 66 is pasted over the entire back surface of the display surface of the monitor 69. The second support 66 is a thin plate made of a hard metal such as a steel plate or a stainless steel plate and rich in restoring force. The second support 66 is wound around the winding / feeding mechanism 15 together with the monitor 69, but in a no-load state before this winding, the cross section perpendicular to the feeding direction Y1 warps in a curved shape due to the restoring force, An attempt is made to straighten in the long axis direction, that is, the feeding direction Y1 of the monitor 69. As a result, the monitor 69 attached to the second support 66 is pulled in the feed-out direction Y1, and the bending is removed.

  The warping direction of the second support 66 is not particularly limited, and the display surface of the monitor 69 may be configured to warp inward as shown in FIG. 21, or the display surface of the monitor 69 as shown in FIG. May be configured to warp outward.

  Since the second support 66 has elasticity, when the second support 66 is wound on the take-up / feed-out mechanism 15 together with the monitor 69, the cross section becomes linear against the self-repulsive force, and the second support 66 is easily wound into a tape measure. Is done.

<Fourth embodiment>
A mechanism for removing the deflection of the monitor 69 may be provided on the side surface of the monitor mounting portion 63. That is, as shown in FIG. 23, a groove-shaped monitor guide 63a is provided on the side surface of the concave flat monitor mounting portion 63. As shown in FIG. 24, when a monitor 69 is extended along the monitor guide 11b after a narrow band-like support 67 is fitted to the monitor guide 63a, the deflection of the support 67 is regulated by the monitor guide 63a. Thus, the bending of the monitor 69 is eliminated.
