Description

  The present invention relates to an imaging apparatus using a proximity detection sensor, and more particularly to a method for controlling a display device (TFT) and an input device (touch panel).

  A conventional camera has a display device (TFT) on the back surface, and is used to display an image being photographed and to make settings. In a camera having a finder, when it is desired to perform finder shooting, if the display device (TFT) is in a lighting state at a position close to the finder, it is dazzling and hinders shooting. Therefore, a proximity detection sensor is mounted on the camera, and the display device is controlled to be turned off according to the detection state of the proximity detection sensor.

  According to Patent Literature 1, a touch panel is provided on the rear display device, and control of the display device is realized using this touch panel. By simultaneously receiving the first operation signal (release button) and the second operation signal (touch panel), it is detected that the photographer is in the eyepiece state looking into the eyepiece viewfinder.

  According to Patent Document 2, in accordance with the posture of the rear display device fastened and supported by the hinge shaft, control for invalidating the eyepiece detection is performed when the possibility of erroneous detection is high.

  However, in Patent Document 1, when a function of operating a touch panel with a finger during a photographing operation is mounted, the display device is controlled to be turned off according to the above configuration, and cannot be operated. In Patent Document 2, when a camera is actually used, the camera holding method and the way of moving the hand during a touch operation change depending on the posture of the camera and the position of the rear display device, so the possibility of erroneous detection changes. In fact, even under conditions where the possibility of erroneous detection is low, the eyepiece detection is invalidated, and the original function of reducing glare at the time of eyepiece is hindered.

[Example 1]
DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described in detail with reference to the accompanying drawings. In addition, the same code | symbol is attached | subjected to a common part.

  FIG. 1 is a block diagram illustrating a main electrical configuration of a digital single-lens reflex camera 1 which is a photographing apparatus main body of the present embodiment. A central processing unit (hereinafter referred to as “MPU”) 1000 comprising a microcomputer built in the digital single-lens reflex camera 1 controls the operation of the camera, and executes various processes and instructions for each element. To do. The EEPROM 1000a built in the MPU 1000 can store time information of the time measuring circuit 109 and other information.

  Connected to the MPU 1000 are a mirror drive circuit 101, a focus detection circuit 102, a shutter drive circuit 103, a video signal processing circuit 104, a switch sense circuit 105, and a photometry circuit 106. Further, an LCD drive circuit 107, a battery check circuit 108, a time measurement circuit 109, a power supply circuit 110, and an imaging unit drive circuit 111 are connected. These circuits operate under the control of the MPU 1000.

  The MPU 1000 communicates with the lens control circuit 201 in the photographing lens unit 200a via the mount contact 21. The mount contact 21 also has a function of transmitting a signal to the MPU 1000 when the photographing lens unit 200a is connected. Accordingly, the lens control circuit 201 communicates with the MPU 1000 and drives the photographing lens 200 and the diaphragm 204 in the photographing lens unit 200a via the AF driving circuit 202 and the diaphragm driving circuit 203. In FIG. 1, only one photographing lens 200 is shown for the sake of convenience, but it is actually constituted by a large number of lens groups.

  The AF drive circuit 202 is constituted by, for example, a stepping motor, and adjusts the focus of the photographing light flux to the imaging element 33 by changing the focus lens position in the photographing lens 200 under the control of the lens control circuit 201. The aperture driving circuit 203 is configured by, for example, an auto iris or the like, and changes the aperture 204 under the control of the lens control circuit 201 to obtain an optical aperture value.

  The main mirror 6 guides a photographic light beam passing through the photographic lens 200 to the penta roof mirror 22 and transmits a part thereof while being held at an angle of 45 ° with respect to the photographic optical axis shown in FIG. Guide to submirror 30. The sub mirror 30 guides the photographic light beam transmitted through the main mirror 6 to the focus detection sensor unit 31.

  The mirror drive circuit 101 is composed of, for example, a DC motor and a gear train, and drives the main mirror 6 to a position where the subject image can be observed by the finder and a position where the subject image is retracted from the photographing light beam. When the main mirror 6 is driven, the sub mirror 30 is simultaneously moved to a position for guiding the photographing light beam to the focus detection sensor unit 31 and a position for retracting from the photographing light beam.

  The focus detection sensor unit 31 is composed of a field lens, a reflection mirror, a secondary imaging lens, a diaphragm, a line sensor composed of a plurality of CCDs, etc. arranged in the vicinity of an imaging surface (not shown), and a phase difference type focus detection. I do. A signal output from the focus detection sensor unit 31 is supplied to the focus detection circuit 102, converted into a subject image signal, and then transmitted to the MPU 1000. The MPU 1000 performs focus detection calculation by a phase difference detection method based on the subject image signal. Then, the defocus amount and the defocus direction are obtained, and based on this, the focus lens in the photographing lens 200 is driven to the in-focus position via the lens control circuit 201 and the AF drive circuit 202.

  The penta roof mirror 22 converts and reflects the photographing light beam reflected by the main mirror 6 into an erect image. The photographer can observe the subject image from the eyepiece lens 18. The penta roof mirror 22 also guides a part of the photographic light beam to the photometric sensor 23. The photometric circuit 106 obtains the output of the photometric sensor 23, converts it into a luminance signal for each area on the observation surface, and outputs it to the MPU 1000. The MPU 100 calculates an exposure value based on the luminance signal.

  The shutter unit (mechanical focal plane shutter) 32 has a shutter front curtain in a light shielding position and a shutter rear curtain in an exposure position when a photographer observes a subject image with a finder. Next, at the time of shooting, the shutter front curtain travels from the light shielding position to the exposure position, passes light from the subject, and the image sensor 33 captures an image. After the elapse of a desired shutter time, the shutter trailing curtain moves from the exposure position to the light shielding position, and the photographing is completed. The mechanical focal plane shutter 32 is controlled by the shutter drive circuit 103 that has received a command from the MPU 1000.

  The imaging unit 400 is a unit in which the optical low-pass filter 410 and the imaging device 33 are united together with other components described later. The image sensor 33 photoelectrically converts a subject image. In this embodiment, a CMOS sensor is used, but there are various other types such as a CCD type, a CMOS type, and a CID type. A device may be employed. The optical low-pass filter 410 disposed in front of the image sensor 33 is a single birefringent plate made of quartz.

  In the vicinity of the imaging unit 400, an imaging unit drive mechanism 600, which will be described later, is disposed. The imaging unit drive mechanism finely drives the imaging unit back and forth along the imaging optical axis direction in order to determine the lens driving direction in focus when performing contrast AF using the imaging element.

  The clamp / CDS (correlated double sampling) circuit 34 performs basic analog processing before A / D conversion, and the clamp level can be changed. The AGC (automatic gain adjusting device) 35 performs basic analog processing before A / D conversion, and can change the AGC basic level. The A / D converter 36 converts the analog output signal of the image sensor 33 into a digital signal.

  The video signal processing circuit 104 performs overall image processing by hardware such as gamma / knee processing, filter processing, and information composition processing for monitor display on the digitized image data. The image data for monitor display from the video signal processing circuit 104 is displayed on the color liquid crystal monitor 19 via the color liquid crystal drive circuit 112. The video signal processing circuit 104 can also store image data in the buffer memory 37 through the memory controller 38 in accordance with an instruction from the MPU 1000. Further, the video signal processing circuit 104 can also perform image data compression processing such as JPEG. When continuous shooting is performed, such as continuous shooting, image data can be temporarily stored in the buffer memory 37, and unprocessed image data can be sequentially read out through the memory controller 38. Thereby, the video signal processing circuit 104 can sequentially perform image processing and compression processing regardless of the speed of the image data input from the A / D converter 36.

  The memory controller 38 has a function of storing the image data input from the external interface 40 in the memory 39 and outputting the image data stored in the memory 39 from the external interface 40. The external interface 40 corresponds to the video signal output jack 16 and the USB output connector 17 in FIG. As the memory 39, a flash memory that can be attached to and detached from the camera body is used.

  The switch sense circuit 105 transmits an input signal to the MPU 100 according to the operation state of each switch. The switch SW1 (7a) is turned on by the first stroke (half press) of the release button 7. The switch SW2 (7b) is turned on by the second stroke (full press) of the release button 7. When the switch SW2 (7b) is turned on, an instruction to start photographing is transmitted to the MPU 1000. Further, the main operation dial 8, the sub operation dial 20, the shooting mode setting dial 14, the main switch 43, and the cleaning instruction switch 44 are connected.

  The LCD drive circuit 107 drives the LCD display panel 9 and the in-finder liquid crystal display device 41 in accordance with instructions from the MPU 1000.

  The battery check circuit 108 performs a battery check according to an instruction from the MPU 1000 and transmits the detection result to the MPU 1000. The power supply 42 supplies power to each element of the camera.

  The time measuring circuit 109 measures the time and date from when the main switch 43 is turned off to when it is turned on, and transmits the measurement result to the MPU 100 in accordance with an instruction from the MPU 1000.

  A sounding body driving circuit 114 drives the sounding body 115 in accordance with an instruction from the MPU 1000 when alerting the user such as when AF is in focus or when an error occurs.

  Reference numeral 116 denotes a light emitter driving circuit that causes a light emitter 117 provided on the front of the camera, which will be described later, to emit light in a scene where AF auxiliary light or red-eye reduction of the subject is required according to an instruction from the MPU 1000.

  The rotation shaft 308a is formed integrally with the display mounting portion 308, and is a rotation shaft for rotating the image display portion 2 with respect to the digital camera body 1 about the rotation center axis B of FIG. It becomes. The leaf spring 310 gives a predetermined torque to the rotation shaft 308a.

  The rotation stopper 311 is brought into contact with a protrusion (not shown) formed on the base metal plate 312 to restrict the rotation of the image display unit 2 around the rotation shaft 308a within a certain range.

  FIG. 5 is a view of the P-P cross section of the back cover unit of the present embodiment, the subject side being the lower side in the drawing, as viewed from the top of the main body, and represents the open / close detection configuration of the hinge mechanism 3.

  The flexible substrate 53 is fixed to the back cover 50 with a screw 55 by a metal holder 54. The flexible substrate 43 is mounted with operation parts (not shown), speakers (not shown), detector switches (not shown), and accompanying components (not shown), capacitors (not shown), and other mounting parts.

  The holder 54 is formed so as to cover the mounting surface of the Hall element 56 mounted on the flexible substrate 43, and is fixed to the back cover 50 using a screw 55, thereby holding the Hall element 56.

  The Hall element 56 is used as a magnetic detection means, and in this embodiment, a single pole detection (S pole detection) type is used. In general, there is a bipolar detection type.

  Hall elements generally have sensitivity characteristics specific to the magnetic flux density regardless of the detection type. When a magnetic flux density exceeding the sensitivity is detected, the output voltage is switched and the switching of the output voltage is detected. To use. In this embodiment, the switching of the output voltage is detected by an integrated circuit (not shown) mounted on a substrate (not shown).

  The user should not check the display surface 2a when the display surface 2a is closed facing the subject side and when the opening angle of the first rotation center axis A of the image display unit 2 is a predetermined angle or less. Is assumed. At this time, power consumption can be reduced by turning off the TFT liquid crystal panel or the like used for the display surface 2a. Further, the angle at which the user can confirm the display surface 2a varies depending on the exterior design shape of the digital single-lens reflex camera 1, and therefore the opening angle of the display surface 2a can be freely changed according to the exterior design shape.

  FIG. 6 shows a camera posture when the photographer photographs the digital single-lens reflex camera 1 in the present embodiment using the optical viewfinder 10.

  FIG. 6A shows the digital single-lens reflex camera 1 with the grip 5 held by the right hand and the lens attached to the mount 11 with the left hand, the digital single-lens reflex camera 1 held in the normal position, and the eyepiece on the optical viewfinder 10. And indicate the posture in use. In this embodiment, this state is defined as camera posture 1.

  FIG. 6B shows the digital single-lens reflex camera 1 with the grip 5 held by the right hand and the lens mounted on the mount 11 with the left hand, and the digital single-lens reflex camera 1 in the vertical position with the grip 5 side down. The posture is held and is in contact with the optical viewfinder 10 and used. In this embodiment, this state is defined as camera posture 2.

  At this time, when the posture is changed from the normal position held in the camera posture 1 to the camera posture 2, the digital single-lens reflex camera 1 is optically illuminated by a posture detection sensor (not shown) mounted on the digital single-lens reflex camera 1. Detects changes in posture when rotating in the axial direction. In this embodiment, a rotation posture detection element is mounted on a substrate (not shown) as a posture detection sensor (not shown). However, the posture change of the digital single-lens reflex camera 1 such as an acceleration sensor or a gyro sensor is used. Any device can be used as long as it can be detected.

  FIG. 6C shows the digital single-lens reflex camera 1 with the grip 5 held by the right hand and the lens attached to the mount 11 with the left hand, and the digital single-lens reflex camera 1 is in a vertical position with the grip 5 side up. The posture is held and is in contact with the optical viewfinder 10 and used. In this embodiment, this state is defined as camera posture 3.

  FIG. 7 is a control flow of the display device / touch panel in the present embodiment in the opening angle of the first rotation center axis A, the rotation angle of the second rotation center axis B, and the camera posture. When the proximity sensor enters the detection state, the zoom operation ring contact detection sensor 501a, the focus operation ring contact detection sensor 502a, the camera contact detection sensor 505, the opening angle of the first rotation center axis A, and the second rotation center axis B Are detected, and the operations of the image display unit 2 and the touch input unit 3 are changed depending on the combination of the detected states.

  Specific operations in this embodiment will be described below.

  First, in a state where the camera contact detection sensor 505 is detecting, the opening angle of the first rotation center axis A is 0 to 15 (°), the second rotation center axis B is 180 (°), and the camera posture 2 The case will be described.

  When the digital single-lens reflex camera 1 is in the above state, the camera contact detection sensor 505 detects when the photographer touches the touch input unit 4 and performs an input operation. It can be considered that the grip is performed with the right hand and the input operation is performed with the left hand.

  At this time, in the case of the camera posture 2, the proximity detection sensor 100 is positioned on the right side of the optical viewfinder 10 when viewed from the photographer, and therefore the possibility that the photographer's left hand is detected by the proximity detection sensor 100 is low. In this state, when the proximity detection sensor 100 is in the detection state, it can be considered that the photographer is in contact with the optical viewfinder 10 and is in use. Therefore, as shown in the flow (3), the image display unit 2 is turned off (light-off state) so that the anti-glare operation is performed, and the touch input unit 4 is turned off (input disabled state) so that a part of the face is touch input unit. 4 prevents an unintended input operation by touching 4 and enables comfortable viewfinder shooting.

  Next, in a state where the camera contact detection sensor 505 detects, the opening angle of the first rotation center axis A is 0 to 15 (°), the second rotation center axis B is 180 (°), and the camera posture The case of 3 will be described.

  When the digital single-lens reflex camera 1 is in the above state, the camera contact detection sensor 505 detects when the photographer touches the touch input unit 4 and performs an input operation. It can be considered that the grip is performed with the right hand and the input operation is performed with the left hand. At this time, in the case of the camera posture 3, the proximity detection sensor 100 is positioned on the left side of the optical viewfinder 10 when viewed from the photographer. Therefore, when performing an input operation to the touch input unit 4, the proximity detection sensor 100 uses the proximity detection sensor 100. The left hand is detected. Therefore, as shown in the flow (2), the image display unit 2 is turned on (lighted state) and the touch input unit 4 is turned on (input state), thereby enabling a comfortable input operation to the touch input unit 4.

  Here, the basis for setting the opening angle of the first rotation center axis A will be described.

  The opening angle is set to a range of 173 (°) or less in consideration of variations in the detection angle of the detection switch 350 caused by variations in manufacturing dimensions of the hinge mechanism 3. The second rotation center axis B is in a range of 175 (°) or less for the same reason, and is a value considering variation in the detection angle of the detection switch 351. It can be changed freely within a range of less than 180 (°) in response to variations in the detection angle. In the present embodiment, three ranges of detection angles 0 (°) to 15 (°), 15 (°) to 173 (°), and 173 (°) to 175 (°) of the rotation center axis B are discriminated.

  Next, in a state where the zoom operation ring contact detection sensor 501a or the focus operation ring contact detection sensor 502a is detecting, the opening angle of the first rotation center axis A is 0 to 15 (°) and the second rotation center A case where the axis B is 180 (°) and the camera posture is 2 will be described.

  When the digital single-lens reflex camera 1 is in the above-described state, when the photographer touches the touch input unit 4 and performs an input operation, the zoom operation ring contact detection sensor 501a or the focus operation ring contact detection sensor 502a detects. Therefore, it can be considered that the photographing lens 500 is held with the left hand and the input operation is performed with the right hand.

  At this time, in the case of the camera posture 2, the proximity detection sensor 100 is located on the right side of the optical viewfinder 10 when viewed from the photographer. Therefore, when performing an input operation to the touch input unit 4, The right hand is detected. Therefore, as shown in the flow (2), the image display unit 2 is turned on (lighted state) and the touch input unit 4 is turned on (input state), thereby enabling a comfortable input operation to the touch input unit 4.

  Next, in a state where the zoom operation ring contact detection sensor 501a or the focus operation ring contact detection sensor 502a is detecting, the opening angle of the first rotation center axis A is 0 to 15 (°) and the second rotation center A case where the axis B is 180 (°) and the camera posture is 3 will be described.

  When the digital single-lens reflex camera 1 is in the above-described state, when the photographer touches the touch input unit 4 and performs an input operation, the zoom operation ring contact detection sensor 501a or the focus operation ring contact detection sensor 502a detects. Therefore, it can be considered that the photographing lens 500 is held with the left hand and the input operation is performed with the right hand.

  At this time, in the case of the camera posture 3, the proximity detection sensor 100 is located on the left side of the optical viewfinder 10 when viewed from the photographer, and therefore, the possibility that the right hand of the photographer is detected by the proximity detection sensor 100 is low. In this state, when the proximity detection sensor 100 is in the detection state, it can be considered that the photographer is in contact with the optical viewfinder 10 and is in use. Therefore, as shown in the flow (3), an anti-glare operation is performed by turning off the image display unit 2 (light-off state), and a part of the face is touch-input unit by turning off the touch input unit 4 (input disabled state). 4 prevents an unintended input operation by touching 4 and enables comfortable viewfinder shooting.

  As described above, in the case of controlling the image display unit 2 and the touch input unit 4 based on the opening angle of the first rotation center axis A and the rotation angle of the second rotation center axis B, the camera posture, and the detection state of the contact detection sensor. The division is summarized in FIGS. 8 and 9 below.

  FIG. 8 is a diagram illustrating the case classification of the control of the image display unit 2 and the touch input unit 4 when the grip detection sensor 505 is in the detection state in the present embodiment.

  FIG. 9 is a diagram showing a case classification of control of the image display unit 2 and the touch input unit 4 when the zoom operation ring contact detection sensor 501a or the focus operation ring contact detection sensor 502a is in the detection state in the present embodiment. is there.

  As described in the above flow, in this case, in the digital single-lens reflex camera main body 1 in which the image display unit 2 is supported by the hinge mechanism 3, shooting using the optical finder 10 and the touch input unit 4 are used. The input operation performed can be performed comfortably.

  As mentioned above, although preferable embodiment of this invention was described, this invention is not limited to these embodiment, A various deformation | transformation and change are possible within the range of the summary.
