Description

  The present invention relates to a display device with a touch panel, and more particularly to a display device with a touch panel capable of various operations by operating a touch panel located on a display screen.

  Devices such as electronic cameras such as digital cameras, camera-equipped mobile phones, personal digital assistants (PDAs), and portable game devices are provided with a display device such as a liquid crystal monitor. Through images and captured images are displayed.

  By the way, in recent years, downsizing of devices as described above is rapidly progressing. However, for display devices, a larger screen size is desired in order to display powerful and easy-to-view images. Due to this requirement, a display device with a large screen is mounted in the device as described above. However, if the area occupied by the display screen increases with respect to the size of the device main body, the grip portion that grips the device during shooting is reduced. There is a drawback in that the operability of the device is deteriorated because it is difficult for the user to hold the device. Also, there is a problem that a part of the image becomes invisible because the display screen is touched with a hand holding the device.

  Therefore, in order to solve such a problem, the applicant of the present application disclosed in Patent Document 1 enables the reproduction of a powerful image on a large screen monitor during reproduction, and the display screen hidden by the hand holding the camera during photographing. We have proposed a camera with a monitor that uses a part of it as a touch panel on which no screen is displayed and improves the grip by making it possible to hold the part of the touch panel.

According to the camera of Patent Document 1, since only the composition is confirmed on the display screen at the time of shooting and the image is not viewed, there is no need for a large screen. Rather, it is desirable to improve the shooting operability by improving the grip. For the reason, the touch panel is also used as a grip part, and the image is reduced and displayed on the screen in a range other than that used as the touch panel.

The lens barrier 16 is recorded / reproduced via an interlocking mechanism (not shown) so as to operate in conjunction with the recording / reproduction switching operation by the recording / reproduction switching lever (recording / reproduction switching means) 18 shown in FIG. The switch lever 18 is connected.

  As shown in FIG. 1, the left part of the camera body 20 including the imaging unit 12 is formed with a grip part 22 that swells forward so that the photographer can easily hold the camera body 20 with the right hand. The camera body 20 is formed in a horizontally long shape, and a shutter button 24 and a frame advance / frame return button 26 are disposed on the upper surface thereof. Further, a strobe light emitting unit 28 is provided at the upper right corner of the front surface of the camera body 20.

  On the back side of the grip portion 22, a power switch 30 for switching on / off of the main power source is disposed as shown in FIGS. The power switch 30 is slidably mounted in the vertical direction along the back surface of the camera body 20 and is urged upward by the urging means (not shown). That is, the power is turned ON / OFF by sliding the power switch 30 downward in FIG.

  A horizontally long monitor (display screen) 32 is provided on the back of the electronic camera 10. The monitor 32 is composed of a liquid crystal display (LCD), and has a horizontally large screen as much as possible with respect to the size of the horizontally long camera body 20. The standard size (aspect ratio 3) is used in the full screen shown in FIG. : 4) image can be displayed. The monitor 32 can also reduce and display a standard size image in the form shown in FIG. In FIG. 3, reference numeral 34 denotes a camera board on which an electronic circuit is mounted, and reference numeral 36 denotes a built-in rechargeable battery.

  On the other hand, a rectangular touch panel 38 is provided on the right side adjacent to the monitor 32 as shown in FIG. The touch panel 38 is formed of a bendable sheet, for example, a plastic sheet, and is hung on a pair of rollers 40 and 40 provided on the side of the camera body 20 as shown in FIG. Is bent and moved between a drawer position that covers the right side (part) of the monitor 32 on the front side and a storage position that is retracted from the screen of the monitor 32 on the side and back sides of the monitor 32 shown in FIGS. The Further, the touch panel 32 is urged in the storage direction (the direction of arrow A shown in FIGS. 3 and 5) by an urging member (not shown). By disposing the touch panel 38 in the camera body 20 in such a form, the storage space of the touch panel 38 can be saved, and the camera body 20 can be made compact. In addition, the touch panel 38 should just be a material which can be bent, and can apply organic EL (Electro Luminescence), inorganic EL, etc. other than a plastic sheet.

  On the touch panel 38, a zoom tele button 42, a zoom wide button 44, a macro shooting switching button 46, a flash light emission button 48, and the like that are operated at the time of shooting are arranged at predetermined positions. The CPU 50 shown in FIG. 6 changes the content displayed on the monitor 32 in response to signals received from these buttons 42 to 48. As a finger detection method using these buttons 42 to 48, various means such as a resistance film type, a capacitance type, an ultrasonic type, and an optical type can be used.

  In addition, a recording / reproduction switching lever 18 for moving the touch panel 38 is provided on the upper back of the camera body 20 as shown in FIGS. The recording / playback switching lever 18 is slidably mounted along a slit 52 formed in the horizontal direction in the camera body 20 and is coupled to the touch panel 38 via a coupling tool (not shown). The recording / reproduction switching lever 18 is slid between the reproduction position shown in FIGS. 2 and 3 and the photographing position shown in FIGS. 4 and 5 along the slit 52, and is moved to the reproduction position and the photographing position. It is locked by a click mechanism (not shown). Accordingly, the touch panel 38 is held against the urging force of the urging member at the storage position illustrated in FIGS. 2 and 3 and the drawer position illustrated in FIGS. 4 and 5.

  Further, the electronic camera 10 has a position sensor for detecting that the recording / reproduction switching lever 18 is located at the reproduction position shown in FIGS. 2 and 3 and the photographing position shown in FIGS. 54 is provided as shown in FIG. A signal indicating the position of the touch panel 38 from the position sensor 54 is output to the CPU 50 that controls and controls the electronic camera 10.

  When the position sensor 54 outputs a signal indicating that it is located at the reproduction position to the CPU 50, the CPU 50 recognizes that the mode is the reproduction mode. Further, when a signal indicating that the camera is located at the photographing position is output from the position sensor 54 to the CPU 50, the CPU 50 recognizes that the mode has been switched from the reproduction mode to the photographing mode. When the signal indicating the reproduction position is input, the CPU 50 sets the image displayed on the monitor 32 to the standard size shown in FIGS. 2 and 3, and when the signal indicating the shooting position is input, The displayed image is set to the reduced size of the standard size shown in FIGS. That is, the CPU 50 has a function of display switching means.

  The reduced size of the image shown in FIGS. 4 and 5 is set to a size that does not hide the image by the touch panel 38 located at the pull-out position. Can be viewed via the touch panel 38, so there is no need to change the image size to a reduced size. Further, the operability is further improved by displaying an image corresponding to the operation on the screen covered with the touch panel 38.

  FIG. 6 is a block diagram showing the overall configuration of the electronic camera 10.

  As shown in the figure, the CPU 50 is connected to each block of the electronic camera 10 via the bus 55, and performs overall control of each block based on operation inputs from the touch panel 38 and the operation switch 56.

  The operation switch 56 includes a shutter button 24, a frame advance / frame return button 26, and a power switch 30, and is a block for performing an operation input to the electronic camera 10. The shutter button 24 is configured in two stages. An S1 = ON signal is generated by “half pressing”, and an S2 = ON signal is generated by “full pressing”. The generated S1 = ON signal and S2 = ON signal are input to the CPU 50, and the CPU 50 detects the pressed state of the shutter button 24 based on the S1 = ON signal and the S2 = ON signal.

  The EEPROM 57 stores a control program for the electronic camera 10 and various setting data necessary for the control. The power supply circuit 58 supplies power to each block of the electronic camera 10. The strobe light 28 is controlled to emit light by a strobe light emission circuit 60 based on a strobe light emission command from the CPU 50 based on the operation of the strobe light emission button 48 of the touch panel 38.

  The electronic camera 10 includes a photographic lens 14, an iris 62, and a CCD 64 as imaging means. The focusing of the photographic lens 14 is performed by moving the focus lens constituting the photographic lens 14 by the focus motor 66, and the zooming is performed by moving the zoom lens constituting the photographic lens 14 by the zoom motor 68. The focus motor 66 and the zoom motor 68 are driven and controlled by a focus motor driver 70 and a zoom motor driver 72, respectively. The CPU 50 outputs a control signal to the focus motor driver 70 for control, and controls the zoom motor driver 72 based on operation signals from the zoom tele button 42, zoom wide button 44, and macro shooting switching button 46 on the touch panel 38. Is output and controlled.

  The diaphragm 62 is constituted by a so-called turret type diaphragm, and for example, the diaphragm value (F value) is changed by rotating a turret plate in which diaphragm holes of F2.8 to F8 are perforated. The iris 62 is driven by an iris motor 74. The iris motor 74 is driven and controlled by an iris motor driver 76. The CPU 50 controls the iris motor driver 76 by outputting a control signal.

  Image light indicating the subject is imaged on the light receiving surface of the CCD 64 via the photographing lens 14 and the diaphragm 62. A large number of photosensors are arranged on the light receiving surface of the CCD 64, and an optical image of a subject formed on the light receiving surface is converted into a signal charge of an amount corresponding to the amount of incident light by each photosensor. The signal charges accumulated in the respective photosensors are sequentially read according to the timing pulse supplied from the timing generator (TG) 78 and output to the analog signal processing circuit 80 as a voltage signal corresponding to the signal charges.

  The CCD 64 is provided with a charge sweeping drain, and the signal charge accumulated in each photosensor is controlled by sweeping the signal charge accumulated in each photosensor to the charge sweeping drain. Is done.

  The analog signal processing circuit 80 includes a correlated double sampling processing circuit (CDS) and an amplifier (AMP). The voltage signal sequentially read from the CCD 64 is amplified by sampling and holding R, G, and B signals for each pixel by the analog signal processing circuit 80 and applied to the A / D converter 82.

  The A / D converter 82 converts analog R, G, and B signals that are sequentially input into digital R, G, and B signals and outputs the digital R, G, and B signals that are output from the A / D converter 82. The G and B signals are temporarily stored in the memory (SDRAM) 86 via the image input controller 84. The R, G, and B signals are output from the SDRAM 86 to the image signal processing circuit 88.

  The image signal processing circuit 88 performs predetermined signal processing such as offset control, gain control processing including white balance correction and sensitivity correction, and gamma correction processing on the input image signal, and the processed image data is processed. Output to the VRAM 90.

  The VRAM 90 includes an A area and a B area that can store image data for one frame, and the image data for one frame is alternately rewritten in the A area and the B area. The rewritten image data is alternately read out.

  The image data read from the VRAM 90 is encoded by the video encoder 92 and output to the monitor 32 of the camera 10. The monitor 32 is controlled by the liquid crystal drive circuit 94 and illuminated from the back surface of the monitor 32 by the backlight unit 96. The user determines the composition based on the through image displayed on the monitor 32 at the time of shooting, and checks the focus state. This through image is the reduced size image shown in FIG. Note that when the light-transmissive touch panel 38 is applied, the through image is an enlarged image shown in FIG.

  In the photographing mode shown in FIG. 4, when the shutter button 24 is half-pressed (S1 = ON), automatic exposure adjustment (AE) and autofocus (AF) are activated. That is, the image data output from the A / D converter 82 is input to the AE / AWB detection circuit 98 and the AF detection circuit 100 via the image input controller 84.

  For example, the AE / AWB detection circuit 98 integrates R, G, and B image data for each R, G, and B for each divided region obtained by dividing the imaging region into 64 (horizontal 8 and vertical 8). The accumulated data for each region R, G, and B is output to the CPU 50.

  The AF detection circuit 100 calculates a contrast evaluation value representing the contrast of an image in a specific focus area (for example, the center of the imaging region) set in advance, and outputs the contrast evaluation value to the CPU 50.

  The CPU 50 outputs a control signal to the focus motor driver 70 based on the contrast information input from the AF detection circuit 100, performs AF control of the photographing lens 14, and focuses on the main subject.

  Further, the CPU 50 calculates the brightness (EV value) of the subject based on the integrated data input from the AE / AWB detection circuit 98, and based on this EV value, the aperture value (F value) of the aperture 62 and the CCD 64 The shutter speed (charge accumulation time) is determined.

  When AE and AF are completed and the shutter button 20 is fully pressed (S2 = ON), the CPU 50 outputs a drive signal to the iris motor driver 76 based on the determined aperture value (F value), and determines the determined aperture. The aperture 62 is driven and controlled so that the aperture diameter is F (value), and the charge accumulation time of the CCD 64 is controlled so that the determined shutter speed is obtained.

  The image data for one frame captured in this way is input from the image input controller 84 to the SDRAM 86 via the analog signal processing circuit 80 and the A / D converter 82 and temporarily stored therein. Then, the data is read out from the SDRAM 86 to the image signal processing circuit 88, where predetermined signal processing including generation processing (YC processing) of luminance data and color difference data is performed.

  The image data after the signal processing is temporarily stored in the SDRAM 86 and then output to the compression / decompression processing circuit 102, where predetermined compression processing such as JPEG (Joint Photographic Experts Group) is executed. Then, the image data is temporarily stored again in the SDRAM 86, then read out by the memory controller 104, and recorded on the recording medium 106 mounted in the card slot. Note that the recording format of the image data is not limited to the JPEG method, and an MPEG or other recording method may be adopted. The means for storing the image data is not limited to the semiconductor memory represented by the recording medium 106, and various media such as a magnetic disk, an optical disk, and a magneto-optical disk can be used. Further, the image data may be recorded on a recording medium (internal memory) built in the electronic camera 10 without being limited to these removable media.

  When the operation mode is switched to the reproduction mode by operating the recording / reproduction switching lever 18, the image data shot and recorded in this way is displayed on the monitor 32 as shown in FIGS. In the reproduction mode, the image data recorded on the recording medium 106 is read out to the SDRAM 86 and output from the SDRAM 86 to the compression / decompression processing circuit 102. The decompression process is performed by the compression / decompression processing circuit 102, and the processed image data is temporarily stored in the SDRAM 86 and then output to the monitor 32 via the video encoder 92. As a result, the image data recorded on the recording medium 106 is reproduced and displayed on the monitor 32. By operating the frame advance / frame return button 26, the user can perform frame advance and frame return of the reproduced image.

  When an external display such as a PC or a television is connected to the electronic camera 10 via the video input / output terminal 108 in the playback mode, the image data recorded on the recording medium 106 is output by the video output circuit 110. It is processed and displayed on this external display. The electronic camera 10 is connected to an external device such as a personal computer via a cradle (not shown) by an external connection interface unit (I / F) 112.

  Next, the operation of the electronic camera 10 configured as described above will be described.

  The touch panel 38 provided on the back surface of the electronic camera 10 is a drawer that covers the storage position retracted from the display screen of the monitor 32 as shown in FIGS. 2 and 3 and a part of the display screen of the monitor 32 as shown in FIGS. The position can be selected. The electronic camera 10 is switched to the reproduction mode by the CPU 50 in FIG. 6 when the touch panel 38 is positioned at the storage position in FIGS. 2 and 3 by the recording / reproduction switching lever 18 with the power switch 30 turned on. At the same time, the display mode is switched to the standard size expanded so that the reproduced image is displayed on the entire display screen of the monitor 32. Further, when the touch panel 38 is positioned at the drawing position in FIGS. 4 and 5 by the recording / playback switching lever 18, the CPU 50 switches to the photographing mode and displays a through image on the screen excluding the overlapping part of the touch panel 38. The display format can be switched to a reduced standard size. Further, the surplus screen 120 under the reduced standard size displays characters such as the chapter number, F value, and shutter speed at the time of shooting.

  In this way, in the shooting mode that does not require a large screen for determining the composition, the touch panel 38 is positioned at a pull-out position that covers a part of the display screen of the monitor 32, so that the area used as the grip portion can be reduced. As much as the drawer area can be increased. Therefore, the grip property at the time of imaging | photography with the electronic camera 10 can be improved. In addition, since only the buttons 42 to 48 of the touch panel 38 covering a part of the monitor 32 are touched during operation, the monitor 32 can be prevented from being soiled due to finger operation.

  Furthermore, when the images shown in FIGS. 2 and 3 are reproduced, the touch panel 38 is located at the storage position completely retracted from the display screen of the monitor 32, so that a large screen can be realized at the time of reproduction. The standard size image is displayed in full screen. Therefore, a powerful image can be appreciated.

  In the electronic camera 10 according to the embodiment, the camera body 20 is formed in a horizontally long shape, and the monitor 32 is also formed in a horizontally long shape. The touch panel 38 is housed in the camera body 20 and is taken in and out between the housed position and a drawer position that covers a part of the display screen. As shown in FIG. 4, the touch panel 38 can be suitably used as a grip by inserting and removing the touch panel 38 from the right side of the monitor 32.

  Further, the electronic camera 10 of the embodiment has a lens barrier 16 as shown in FIG. 1, and when the recording / reproduction switching lever 18 is slid from the reproduction position to the photographing position, the lens barrier 16 is interlocked with the sliding operation. It moves to a position where the front surface of the taking lens 14 is opened. Therefore, imaging by the imaging unit 12 becomes possible. When the recording / reproducing switching lever 18 is slid from the photographing position to the reproducing position, the lens barrier 16 moves to a position where the front surface of the photographing lens 14 is closed in conjunction with the sliding operation. Since the imaging unit 12 does not operate during reproduction, the front surface of the photographic lens 14 is blocked by the lens barrier 16 to protect the imaging unit 12. In this way, the operability is improved by operating the lens barrier 16 in conjunction with the slide operation on the recording / reproduction switching lever 18.

  7 and 8 show an electronic camera 200 according to another embodiment, and the same or similar members as those in the electronic camera 10 shown in FIGS.

  In the electronic camera 200 shown in FIG. 7, the recording / reproduction switching lever 18 has a power switch function, and the power OFF position shown in FIG. 7A and the power ON / shooting position (display) shown in FIG. In addition to being locked at the first position covering a part of the screen, the power ON / reproduction operation position shown in FIGS. 7B and 8 (second area covering a smaller area than a part of the display screen) It is a camera of the form latched in position).
