<Configuration block diagram of digital camera 100>
FIG. 2 is a block diagram illustrating a configuration example of the digital camera 100. The lens unit 150 is a lens unit on which an interchangeable photographing lens is mounted. The lens 103 is usually composed of a plurality of lenses, but FIG. 2 simply shows only one lens. The communication terminal 6 is a communication terminal for the lens unit 150 to communicate with the digital camera 100 side, and the communication terminal 10 is a communication terminal for the digital camera 100 to communicate with the lens unit 150 side. The lens unit 150 communicates with the system control unit 50 via these communication terminals 6 and 10. The lens unit 150 controls the aperture 1 via the aperture driving circuit 2 by the internal lens system control circuit 4. The lens unit 150 focuses by displacing the position of the lens 103 via the AF driving circuit 3 by the lens system control circuit 4.

  The shutter 101 is a focal plane shutter that can freely control the exposure time of the imaging unit 22 under the control of the system control unit 50.

  The imaging unit 22 is an imaging device configured by a CCD or a CMOS device that converts an optical image into an electric signal. The imaging unit 22 may include an imaging surface phase difference sensor that outputs defocus amount information to the system control unit 50. The A / D converter 23 converts an analog signal output from the imaging unit 22 into a digital signal.

  The image processing unit 24 performs predetermined processing (resize processing such as pixel interpolation and reduction, color conversion processing, and the like) on the data from the A / D converter 23 or the data from the memory control unit 15. Further, the image processing unit 24 performs a predetermined calculation process using the captured image data, and the system control unit 50 performs exposure control and distance measurement control based on the calculation result obtained by the image processing unit 24. Thereby, TTL (through the lens) type AF (auto focus) processing, AE (auto exposure) processing, EF (flash pre-emission) processing, and the like are performed. The image processing unit 24 further performs predetermined arithmetic processing using the captured image data, and performs TTL AWB (auto white balance) processing based on the obtained arithmetic result.

  The face detection unit 24a is at least one processor or circuit that detects a specific area such as a human face from the image obtained by the image processing unit 24. The organ detecting section 24b is at least one processor or circuit for detecting an organ area from the image obtained by the image processing section 24 and the specific area detected by the face detecting section 24a. Here, the organs are pupils, nose, mouth, and the like, which are elements constituting the face.

That is, the face detection unit 24a and the organ detection unit 24b may be the same processor, circuit, or module having both functions, or may be different processors, circuits, or modules.

  Output data from the A / D converter 23 is written to the memory 32 via the image processing unit 24 and the memory control unit 15. Alternatively, output data from the A / D converter 23 is written to the memory 32 via the memory control unit 15 without passing through the image processing unit 24. The memory 32 stores image data obtained by the imaging unit 22 and converted into digital data by the A / D converter 23, and image data to be displayed on the display unit 28 and the EVF 29. The memory 32 has a sufficient storage capacity for storing a predetermined number of still images, moving images and audio for a predetermined time.

  The memory 32 also serves as an image display memory (video memory). The D / A converter 19 converts the image display data stored in the memory 32 into an analog signal and supplies the analog signal to the display unit 28 and the EVF 29. Thus, the display image data written in the memory 32 is displayed on the display unit 28 or the EVF 29 via the D / A converter 19. Each of the display unit 28 and the EVF 29 performs display according to an analog signal from the D / A converter 19 on a display such as an LCD or an organic EL. A digital signal that has been A / D converted by the A / D converter 23 and stored in the memory 32 is converted into an analog signal by the D / A converter 19, and is sequentially transferred to the display unit 28 or the EVF 29 for display. View display (LV) can be performed. Hereinafter, an image displayed in the live view display is referred to as a live view image (LV image).

  Various setting values of the camera, such as shutter speed and aperture, are displayed on the outside viewfinder display section 43 via the outside viewfinder drive circuit 44.

  The nonvolatile memory 56 is an electrically erasable / recordable memory, and is, for example, an EEPROM. The non-volatile memory 56 stores constants, programs, and the like for the operation of the system control unit 50. The program referred to here is a program for executing various flowcharts described later in the present embodiment.

  The system control unit 50 is a control unit including at least one processor or circuit, and controls the entire digital camera 100. The system control unit 50 realizes each process of the present embodiment described later by executing the program recorded in the non-volatile memory 56 described above. The system memory 52 is, for example, a RAM, and the system control unit 50 develops, in the system memory 52, constants and variables for operation of the system control unit 50, programs read from the nonvolatile memory 56, and the like. The system control unit 50 also performs display control by controlling the memory 32, the D / A converter 19, the display unit 28, and the like.

  The system timer 53 is a time measuring unit that measures the time used for various controls and the time of a built-in clock.

  The power control unit 80 includes a battery detection circuit, a DC-DC converter, a switch circuit for switching a block to be energized, and the like, and detects whether or not a battery is installed, the type of the battery, the remaining battery level, and the like. Further, the power control unit 80 controls the DC-DC converter based on the detection result and the instruction of the system control unit 50, and supplies a necessary voltage to each unit including the recording medium 200 for a necessary period. The power supply unit 30 includes a primary battery such as an alkaline battery and a lithium battery, a secondary battery such as a NiCd battery, a NiMH battery, and a Li battery, and an AC adapter.

  The recording medium I / F 18 is an interface with a recording medium 200 such as a memory card or a hard disk. The recording medium 200 is a recording medium such as a memory card for recording a captured image, and includes a semiconductor memory, a magnetic disk, and the like.

  The communication unit 54 transmits and receives a video signal and an audio signal to and from an external device connected by a wireless or wired cable. The communication unit 54 is also connectable to a wireless LAN (Local Area Network) or the Internet. In addition, the communication unit 54 can communicate with an external device using Bluetooth (registered trademark) or Bluetooth Low Energy. The communication unit 54 can transmit an image (including an LV image) captured by the imaging unit 22 and an image recorded on the recording medium 200, and can receive image data and other various information from an external device.

  The posture detection unit 55 detects the posture of the digital camera 100 with respect to the direction of gravity. Based on the posture detected by the posture detection unit 55, whether the image photographed by the imaging unit 22 is an image photographed by holding the digital camera 100 horizontally or an image photographed by holding it vertically. Can be determined. The system control unit 50 can add orientation information according to the orientation detected by the orientation detection unit 55 to the image file of the image captured by the imaging unit 22 or rotate and record the image. is there. As the posture detecting unit 55, an acceleration sensor, a gyro sensor, or the like can be used. It is also possible to detect the movement of the digital camera 100 (pan, tilt, lift, or not, etc.) using an acceleration sensor or a gyro sensor as the posture detecting unit 55.

  The eyepiece detection unit 57 detects the approach (eyepiece) and separation (eye separation) of the eye (object) from the eyepiece finder 17 (hereinafter simply referred to as “finder”) with respect to the eyepiece unit 16 (approach detection), and the eyepiece. It is a detection sensor. The system control unit 50 switches display (display state) / non-display (non-display state) of the display unit 28 and the EVF 29 according to the state detected by the eyepiece detection unit 57. More specifically, at least in a photographing standby state and when the switching of the display destination is automatic switching, the display destination is turned on as the display unit 28 and the EVF 29 is not displayed during the non-eyepiece. During the eyepiece operation, the display is set to the EVF 29, the display is turned on, and the display unit 28 is not displayed. As the eyepiece detection unit 57, for example, an infrared proximity sensor can be used, and it is possible to detect the approach of any object to the eyepiece unit 16 of the viewfinder 17 incorporating the EVF 29. When the object approaches, the infrared light emitted from the light emitting unit (not shown) of the eyepiece detection unit 57 is reflected by the object and received by the light receiving unit (not shown) of the infrared proximity sensor. Based on the amount of received infrared light, it is also possible to determine how far the object is from the eyepiece 16 (eyepiece distance). As described above, the eyepiece detection unit 57 performs the eyepiece detection that detects the proximity distance of the object to the eyepiece unit 16. It is assumed that when an object approaching the eyepiece 16 within a predetermined distance from the non-eyepiece state (non-approaching state) is detected, it is detected that the eyepiece has been brought into contact. It is assumed that when the object whose proximity has been detected is separated from the eyepiece state (approaching state) by a predetermined distance or more, it is detected that the eye has been separated. The threshold value for detecting the eyepiece and the threshold value for detecting the eye separation may be different, for example, by providing hysteresis. After detecting the eyepiece, the eyepiece is assumed to be in the eyepiece state until the eye separation is detected. After detecting the eye separation, it is assumed that the eyepiece is in the non-eyepiece state until the eyepiece is detected. Note that the infrared proximity sensor is an example, and the eyepiece detection unit 57 may employ another sensor as long as it can detect the approach of an eye or an object regarded as an eyepiece.

  The operation unit 70 is an input unit that receives an operation (user operation) from a user, and is used to input various operation instructions to the system control unit 50. As shown in FIG. 2, the operation unit 70 includes a mode changeover switch 60, a shutter button 61, a power switch 72, a touch panel 70a, a touch bar 82, and the like. The operation unit 70 includes, as other operation members 70b, a main electronic dial 71, a sub electronic dial 73, a four-way key 74, a SET button 75, a video button 76, an AE lock button 77, an enlargement button 78, a play button 79, Menu button 81 and the like.

  The mode switch 60 switches the operation mode of the system control unit 50 to one of a still image shooting mode, a moving image shooting mode, a playback mode, and the like. The modes included in the still image shooting mode include an auto shooting mode, an auto scene determination mode, a manual mode, an aperture priority mode (Av mode), a shutter speed priority mode (Tv mode), and a program AE mode (P mode). In addition, there are various scene modes, custom modes, and the like, which are shooting settings for each shooting scene. The mode switch 60 allows the user to directly switch to any of these modes. Alternatively, after temporarily switching to the shooting mode list screen with the mode switch 60, the mode may be selectively switched to any of the displayed modes by using another operation member. Similarly, the moving image shooting mode may include a plurality of modes.

  The shutter button 61 includes a first shutter switch 62 and a second shutter switch 64. The first shutter switch 62 is turned on by the so-called half-press (instruction for shooting preparation) during the operation of the shutter button 61, and generates a first shutter switch signal SW1. The system control unit 50 starts a shooting preparation operation such as an AF (auto focus) process, an AE (auto exposure) process, an AWB (auto white balance) process, and an EF (flash pre-flash) process in response to the first shutter switch signal SW1. I do.

  The second shutter switch 64 is turned on when the operation of the shutter button 61 is completed, that is, when the shutter button 61 is fully pressed (photographing instruction), and generates a second shutter switch signal SW2. In response to the second shutter switch signal SW2, the system control unit 50 starts a series of shooting processing operations from reading out the signal from the imaging unit 22 to writing the taken image as an image file on the recording medium 200.

The touch panel 70a and the display unit 28 can be integrally configured. For example, the touch panel 70a is configured so that light transmittance does not hinder display on the display unit 28, and is attached to an upper layer of the display surface of the display unit 28. Then, the input coordinates on the touch panel 70a are associated with the display coordinates on the display surface of the display unit 28. Thereby, it is possible to provide a GUI (graphical user interface) as if the user could directly operate the screen displayed on the display unit 28. The system control unit 50 can detect the following operation or state on the touch panel 70a.
The fact that a finger or a pen that has not touched the touch panel 70a has newly touched the touch panel 70a, that is, the start of touch (hereinafter, referred to as touch-down).
A state in which the touch panel 70a is touched with a finger or a pen (hereinafter, referred to as touch-on).
-A finger or a pen is moving while touching the touch panel 70a (hereinafter referred to as touch-move).
-The finger or pen touching the touch panel 70a has been released (released) from the touch panel 70a, that is, the end of the touch (hereinafter referred to as touch-up (Touch-Up)).
-A state in which nothing is touched on the touch panel 70a (hereinafter, referred to as touch-off)

  When touch-down is detected, touch-on is also detected at the same time. After a touch-down, a touch-on is usually continuously detected unless a touch-up is detected. When a touch move is detected, a touch-on is detected at the same time. Even if a touch-on is detected, a touch move is not detected unless the touch position has moved. After it is detected that all the touched fingers or pens have been touched up, the touch is turned off.

  These operations / states and the coordinates of the position where the finger or pen touches the touch panel 70a are notified to the system control unit 50 via the internal bus. Then, system control unit 50 determines what operation (touch operation) has been performed on touch panel 70a based on the notified information. As for the touch move, the moving direction of the finger or the pen moving on the touch panel 70a can be determined for each of the vertical component and the horizontal component on the touch panel 70a based on the change in the position coordinates. If it is detected that a touch move has been performed for a predetermined distance or more, it is determined that a slide operation has been performed. An operation of quickly moving the finger on the touch panel 70a by a certain distance while touching the finger and releasing the finger is referred to as a flick. In other words, the flick is an operation of quickly tracing the touch panel 70a as if to flick it with a finger. If it is detected that a touch move has been performed at a predetermined speed or more at a predetermined speed or more, and a touch-up is detected as it is, it can be determined that a flick has been performed (it can be determined that there has been a flick following the slide operation). Further, a touch operation of touching a plurality of places (for example, two points) together (by multi-touch) to bring the touch positions closer to each other is referred to as a pinch-in, and a touch operation for moving the touch positions away from each other is referred to as a pinch-out. Pinch out and pinch in are collectively referred to as pinch operation (or simply pinch). The touch panel 70a may be any of various types of touch panels such as a resistive film type, a capacitive type, a surface acoustic wave type, an infrared type, an electromagnetic induction type, an image recognition type, and an optical sensor type. Good. There are a method of detecting that a touch has been made by a touch on the touch panel, and a method of detecting that a touch has been made by a finger or a pen approaching the touch panel, and any method may be used.

Further, the system control unit 50 can detect the following operation or state on the touch bar 82.
The fact that a finger that has not touched the touch bar 82 newly touches the touch bar 82, that is, the start of touch (touch-down (Touch-Down))
A state in which the finger is touching the touch bar 82 (touch-on (Touch-On))
-A finger is moving while touching the touch bar 82 (Touch-Move)
The fact that the finger touching the touch bar 82 has been released (released) from the touch bar 82, that is, the end of the touch (touch-up (Touch-Up)).
A state in which nothing is touched on the touch bar 82 (touch-off (Touch-Off))

  When touch-down is detected, touch-on is also detected at the same time. After a touch-down, a touch-on is usually continuously detected unless a touch-up is detected. When a touch move is detected, a touch-on is detected at the same time. Even if a touch-on is detected, a touch move is not detected unless the touch position has moved. After it is detected that all the touched fingers or pens have been touched up, the touch is turned off.

  These operations / states and the coordinates of the position where the finger is touching the touch bar 82 are notified to the system control unit 50 via the internal bus, and the system control unit 50 determines what kind of information is displayed on the touch bar 82 based on the notified information. It is determined whether an operation (touch operation) has been performed. For the touch move, the movement in the horizontal direction (left / right direction) on the touch bar 82 is detected. If it is detected that the touch position has moved a predetermined distance or more (moved a predetermined amount or more), it is determined that a slide operation has been performed. It is assumed that if there is an operation of releasing the touch within a predetermined time without touching the finger on the touch bar 82 and performing a slide operation, it is determined that a tap operation has been performed. In this embodiment, the touch bar 82 is a capacitive touch sensor. However, another type of touch sensor such as a resistive film type, a surface acoustic wave type, an infrared type, an electromagnetic induction type, an image recognition type, an optical sensor type, etc. may be used.

<Arrangement and operation of touch bar 82>
FIG. 3A is a diagram illustrating an arrangement of the touch bar 82. As shown in FIG. 3A, the touch bar 82 is disposed adjacent to the finder 17 on the back side of the digital camera 100. The touch bar 82 is also arranged adjacent to the sub electronic dial 73 and a thumb rest portion 91 which is a position of a thumb when the digital camera 100 is held by gripping the grip portion 90 with the right hand. The thumb rest portion 91 is generally present above a region where the grip portion 90 on the front side of the digital camera 100 is projected on the back side. Then, as shown in FIG. 3A, a rubber or the like is often attached to indicate the thumb rest portion 91 and enhance the grip feeling.

As described above, in the present embodiment, the touch bar 82 is provided so as to satisfy the following conditions 1 to 3.
Condition 1: On the rear surface of the digital camera 100, a touch bar 82 is provided on the right side (first direction side) of the viewfinder 17.
Condition 2: The touch bar 82 is provided on the left side (the second direction side) of the grip portion 90 on the back surface of the digital camera 100.
Condition 3: In the digital camera 100, the touch bar 82 is provided above the center (the third direction side from the center to the finder side in the direction perpendicular to the first direction).

  This allows the touch bar 82 to be easily operated while looking through the finder 17. Specifically, when the touch bar 82 is adjacent to the thumb rest portion 91, a tap operation, a slide operation to the left and right (X-axis direction), and the like can be performed on the touch bar 82 with the right thumb while holding the grip portion 90. It is easier to do. The touch bar 82 is a non-movable operation member, and is a single operation member covered with a single key top (cover) as shown in FIG. This is because, when the capacitance type operation member has a movable mechanism or a divided structure, the contact of the operation finger is not stable, and the operability and the linearity at the time of the slide operation may be impaired.

  The surface on which the touch bar 82 is operated is the same as the surface on which the sub electronic dial 73 is operated so that it can be easily used together with other dial members. In other words, the surface on which the touch bar 82 is operated is perpendicular to the rotation axis of the sub electronic dial 73. The width of the touch bar 82 in the left-right direction is set so that the sliding direction (left-right direction) of the touch bar 82 can be intuitively understood and the sliding operation of the touch bar 82 can be easily performed. It is longer than the width. In order to prevent the user from unintentionally touching the touch bar 82, the touch bar 82 is provided at the uppermost position among a plurality of operation members provided on the back surface of the digital camera 100. In order to prevent the user from unintentionally touching the touch bar 82, the touch bar 82 is provided on the back surface of the digital camera 100 except for the touch panel 70a, and is the leftmost one of a plurality of operation members provided on the right side of the finder 17. It is provided in.

  FIG. 3B is an enlarged view showing the inside of the touch bar 82 (the lower layer of the key top). As shown in FIG. 3B, inside the touch bar 82, three touch sensor electrodes 302a, 302b, 302c are arranged. Each of the touch sensor electrodes 302a, 302b, and 302c is formed of a copper foil wiring or the like on the printed circuit board 301 and has an electrode shape as shown in FIG. The system control unit 50 can read the voltage (voltage output value) of each of the touch sensor electrodes 302a, 302b, 302c. Then, the system control unit 50 can detect, for each of the touch sensor electrodes 302a, 302b, and 302c, a voltage change amount that is a voltage change amount from a base voltage (a reference value that is adjusted or calibrated according to the environment). is there. The system control unit 50 weights and averages the voltage change amounts (capacitance change amounts) detected for each of the touch sensor electrodes 302a, 302b, and 302c, and sets the touch position in the X-axis direction (lateral direction) to 0 to 255. The signal (touch coordinates) indicated in 256 steps is acquired. 0 indicates the leftmost position (on the finder 17 side), and 255 indicates the rightmost position (on the thumbrest portion 91 side). Although the number of electrodes is three in FIG. 3B, the number of electrodes is not limited to three. Further, the electrode shape is not limited to the shape shown in FIG. Further, the touch coordinates are not limited to 256-level values.

  FIG. 3C is an enlarged view showing a basic operation of the touch bar 82. The touch bar 82 can be assigned a function according to the operation position and operation method. On the touch detection surface (key top) of the touch bar 82, a tap operation (hereinafter referred to as a left tap) is performed on a left portion 82L, which is a partial region on the left side, not on the whole, and a right portion 82R is defined on a right partial region. A function can be individually assigned to a tap operation (hereinafter, right tap). Further, a function can also be assigned to a sliding operation on the key top of the touch bar 82 to the left and right (in the direction indicated by the arrow 310) in distinction from the left tap and the right tap. That is, different functions can be registered for each operation location of the touch bar 82 and for each operation method (for each operation type). The left tap and the right tap are determined, for example, as a left tap if the touch coordinate is 128 or less (left side from the center), and a right tap if the touch coordinate is 129 or more (right side from the center). It is possible to In addition, it is determined that the tap to the center is neither a left tap nor a right tap. For example, a tap with a touch coordinate of 100 or less is a left tap, and a touch with a touch coordinate of 155 or more is a right tap. It may be determined.

  An example of functions assigned to these operations will be described. The left tap is assigned a function of setting the photographing ISO sensitivity of the digital camera 100 to 1/3 step low sensitivity, and the right tap is assigned a function of setting the photographing ISO sensitivity to 1/3 step high sensitivity. The slide operation is assigned a function of increasing / decreasing the shooting ISO sensitivity of the digital camera 100 by 1/3 step for each predetermined distance of the slide operation (each time the touch coordinate moves by a reference distance, for example, 43).

  Furthermore, the functions assigned to these operations can be customized by the user. For example, a change can be made such that a function for automatically setting the shooting ISO sensitivity of the digital camera 100 is assigned to the left tap, and a function for setting the shooting ISO sensitivity to the maximum value is assigned to the right tap. Various other functions can be assigned to the touch bar 82, and many functions can be executed using the touch bar 82.

  Further, the system control unit 50 determines that the finger covers the entire surface of the touch bar 82 when the amount of voltage change in all of the touch sensor electrodes 302a, 302b, and 302c of the touch bar 82 exceeds a certain threshold. This touch operation is determined as a full-screen touch. As shown in FIG. 3D, the full-surface touch is an operation method on the assumption that the user touches the touch bar 82 with the entire abdomen of the right thumb gripping the grip portion 90. The functions assigned to the slide operation, the left tap, and the right tap can be customized by the user, but a unique function is assigned to the full touch, and the function assigned to the full touch cannot be changed. As a result, it is possible to immediately activate both the function of touching the entire surface and the function of the basic operation (slide operation or tap). It should be noted that the validity / invalidity of the operation of the entire surface touch may be settable.

The full touch has the following features.
-The special operation of pointing the thumb, which is the operating finger, in the horizontal direction (X direction) and making contact with the entire joint up to the first joint.-The contact state of the full-face touch is a special contact state that is unlikely to occur in normal operation. There is a feature that the entire surface touch is unlikely to be performed due to an unintended operation because the predetermined function (described later) is always set for the entire surface touch, so the user does not need to remember the set function. -The feature of full-face touch does not change regardless of what function is assigned to left tap, right tap, and slide operation, so that the user can perform full touch with peace of mind.

  The system control unit 50 determines a user operation on the touch bar 82 and executes an assignment function stored in the nonvolatile memory 56 in advance in accordance with the determined user operation. For example, the system control unit 50 changes a setting assigned by the user for each touch operation (a change in at least one of a setting related to exposure, a setting related to WB, and a setting related to AF, etc.). The touch bar 82 can be operated while looking through the viewfinder 17. Therefore, the user may operate the touch bar 82 without visually recognizing it. In this case, since the operation surface is not visually recognized, the user may perform an erroneous operation and unintentionally change the parameters of the shooting setting. Thus, the following erroneous operation prevention control is performed. The state of the touch operation on the touch bar 82 is switched between a valid state (non-locked state, non-restricted state) and an invalid state (locked state, restricted state). In the locked state, the left tap, the right tap, and the slide operation on the touch bar 82 are ignored, and even if these operations are performed, the function assigned to each operation is not executed. In the locked state, the touch bar 82 is locked in response to a 0.5 second touch operation (long touch) that has stopped without sliding on the left key portion 82L of the touch bar 82 (the lock operation has been performed). Release the state and transit to the valid state. Also, in the valid state, the lock state is set in response to a long touch of 2 seconds on the key top left portion 82L (there is a lock operation) or no operation for 10 seconds. Transition. Further, even if the touch bar 82 is in an effective state, a long touch for a certain time (1 second in this embodiment) or more is ignored regardless of the touch position, and a left tap, a right tap, and a slide are performed by the touch operation. Also, do not execute the function assigned to them (touch cancel). The function assigned to the full touch is executed according to the full touch regardless of the valid state or the locked state. When the user performs an unlocking operation or a locking operation, the system control unit 50 does not accept an operation on the touch bar 82 until the user touches up.

  As described above, in the present embodiment, the operation for switching between the valid state and the locked state is shared by a long touch (touch continuation operation) that is relatively unlikely to occur during normal use of the digital camera 100. This makes it difficult to cause unintended switching between the locked state and the valid state, and makes it possible to switch between the locked state and the valid state with high accuracy. A long touch, which continues touching for a predetermined time or more, is a relatively simple operation, and therefore, an operation method for switching between the valid state and the locked state is easy to remember, and the possibility that the user forgets the operation method is low. Further, since the valid state and the locked state are switched by operating the touch bar 82, it is not necessary to provide another operation member for switching between the valid state and the locked state, and the configuration is simple. Further, in the present embodiment, by shortening the touch duration for transitioning to the valid state than the touch duration for transitioning to the locked state, the locked state can be quickly released, and the operation after the locked state is performed. (Such as shooting) can be done quickly.

  The reason why the left portion 82L of the key top is used as an operation area (specific area) for switching between the valid state and the locked state will be described. When the user grips the grip unit 90 with the right hand and operates the touch bar 82 with the thumb of the right hand, an area relatively far from the grip unit 90, such as the key top left portion 82L of the touch bar 82, is not intentionally touched. This is an area that is difficult to touch. Therefore, when there is a long touch on the left key top portion 82L, it can be determined that there is an intention to lock or unlock, and the left key top portion 82L is used as an operation area for switching between a locked state and a valid state. Also, the key top left portion 82L can be said to be a region relatively close to the finder 17. An area, such as the viewfinder 17, which is relatively close to the protrusion protruding from the key top is an operation area for switching between the locked state and the valid state. That is, the left side portion 82L, which is a region on the protruding portion side (left side) with respect to another region (for example, the right side portion 82R) of the touch detection surface of the touch bar 82 different from the left side portion 82L (for example, the right side portion 82R), is used as an operation region for switching between the locked state / effective state. I have. Accordingly, even when the abdomen and the back of the camera come into contact with each other when the digital camera 100 is worn around the neck using the strap, the protrusions are replaced, and the abdomen is attached to the left side 82L of the touch bar 82 that does not protrude from the protrusions. The possibility of touch is low and erroneous unlocking is unlikely to occur. In addition, since a finger hits a projection (a projection in a direction perpendicular to the operation surface of the touch bar 82), an area (left side) of the area of the touch bar 82 that is close to the finder 17 is hardest to touch, and the intention of locking or unlocking is accurately determined. Can be pumped. Note that the finder 17 is at least an extent that the finder 17 cannot be exceeded when the thumb of the hand holding the grip portion 90 is slid to the left on the surface of the digital camera 100 on which the key top of the touch bar 82 is provided. Protruding at height. Further, the finder 17 is a protruding portion which is closest to the touch bar 82 and protrudes from the operation surface.

  Note that a sub electronic dial 73 is disposed as a rotary operation member disposed on the right side of the touch bar 82 and closest to the touch bar 82. When the sub electronic dial 73 is rotated clockwise with the thumb of the hand holding the grip portion 90, the thumb may erroneously touch the key top right portion 82R of the touch bar 82. Similar erroneous contact occurs even when a slide switch that can accept a slide operation for bringing an operation finger closer to the touch bar 82 is arranged near the touch bar 82, even if it is not a rotary operation member. Furthermore, on the right side of the touch bar 82, no operation member is operated with the thumb at a position closer to the touch bar 82 than any of the operation members (on the right side of the touch bar 82 and to the left of any other operation member). There is a thumb rest 91 for putting the thumb in case. Then, a slight movement of the finger from the thumb rest portion 91 may erroneously touch the key top right portion 82R. Therefore, when the locked state is released by a touch operation on the key top right portion 82R, the locked state is released by a user's unintended touch operation on the touch bar 82, and a setting change unintended by the user is performed. There is a risk. For this reason, the touch operation on the key top right portion 82R is not used as a trigger operation for releasing the locked state. That is, even if there is a 0.5 second long touch on the right part 82R, switching from the locked state to the valid state is not performed, and even if there is a two second long touch on the right part 82R, switching from the valid state to the locked state is performed. Is not performed.

  Thus, providing the operation area for switching between the locked state and the enabled state on the left side of the touch surface of the touch bar 82 has an important meaning.

  The face detection / organ detection will be described with reference to FIGS.

  FIG. 4A illustrates a face area detected by the face detection unit 24 a from an image captured by the imaging unit 22 or an image reproduced from the image recorded on the recording medium 200, and a face indicating the detected face area. 5 is a display example on the display unit when a frame 401 is displayed while being superimposed on an image. The face detection unit 24a detects a human face from the image. At this time, it is also possible to determine the size of the face, the direction of the face, and the like. The user can designate (select) a face area as a main subject to be subjected to AF or a subject to be subjected to color correction or the like by a touch operation on the touch panel 70a based on these pieces of information.

  FIG. 4B illustrates a face and an organ detected by the face detection unit 24a and the organ detection unit 24b from an image captured by the imaging unit 22 or an image reproduced from an image recorded on the recording medium 200, and the detected face is detected. 6 is a display example in a case where organ frames 402 and 403 indicating the organ regions are displayed so as to be superimposed on an image. The organ frame 402 is an index indicating the area of the pupil on the left side of the screen. The organ frame 403 is an index indicating a pupil region on the right side of the screen. Based on these pieces of information, the user can determine the size and orientation of the organ, and can specify (select) the detected organ area by a touch operation.

  When a face and its organs, for example, a left eye and a right eye, are detected by the face detection unit 24a and the organ detection unit 24b, based on whether the touch position in touch down or touch up is a face area, a left eye area, or a right eye area. It is conceivable to specify an area. Here, the face area is an area of the face area that is neither the left eye area nor the right eye area. However, in the touch operation of touch-down or touch-up, the user may not be able to specify the intended region well. For example, even if the user intends to specify the right eye area and touches the inside of the right eye area, the user actually touches the outside of the right eye area with a slight deviation, and the entire face or the left eye may be specified . This problem is more remarkable when the detected face or organ is small, or when the position or size of the subject in the entire image fluctuates like an LV or a moving image. Also, the reason that the area that the user intended can not be specified well is that when specifying a small target such as the pupil or face, the specified target is hidden by the touched finger, and the user can successfully touch the position as intended. It is also difficult to confirm that they are running. On the other hand, in the present embodiment, by using the touch bar 82, the user can more surely specify the intended area without hiding the specified object with the finger.

  FIG. 5 is an example of face and organ data recorded for managing the face and its organs detected by the face detection unit 24a and the organ detection unit 24b. For example, FIG. 5 shows fifteen pieces of data relating to the face recognized by the digital camera 100 in FIGS. 4A and 4B. This data is recorded in the nonvolatile memory 56 or the like.

  The face number 503 is an identifier indicating a face appearing in the image captured by the imaging unit 22. If a plurality of faces are shown in the image, this identifier is set differently for each face.

  The X coordinate 504 is the X coordinate of the face frame 401 indicated by the face number 503. The Y coordinate 505 is the Y coordinate of the face frame 401 indicated by the face number 503. The X coordinate 504 and the Y coordinate 505 indicate the coordinates of the vertex at the upper left of the face frame 401 when viewed from the screen.

  The width 506 is the width of the face frame 401 of the face indicated by the face number 503. The height 507 is the height of the face frame 401 of the face indicated by the face number 503.

  The first pupil 508 is data indicating whether a pupil (organ frame 402) on the left side of the screen is detected. For example, true is stored in the first pupil 508 when the organ frame 402 is detected, and false when it is not detected. When false is stored in the first pupil 508, no numerical value is stored in the X coordinate 509 to the height 512 described later.

  The X coordinate 509 is the X coordinate of the organ frame 402 indicated by the first pupil 508. The Y coordinate 510 is the Y coordinate of the organ frame 402 indicated by the first pupil 508. The X coordinate 509 and the Y coordinate 510 are the coordinates of the vertex at the upper left of the screen of the organ frame 402.

  The width 511 is the width of the pupil organ frame 402 indicated by the first pupil 508. The height 512 is the height of the pupil organ frame 402 indicated by the first pupil 508.

  The second pupil 513 is data indicating whether or not the pupil (organ frame 403) on the right side of the screen has been detected. For example, true is stored in the second pupil 513 when the organ frame 403 is detected, and false when it is not detected.

  The X coordinate 514 is the X coordinate of the organ frame 403 indicated by the second pupil 513. The Y coordinate 515 is the Y coordinate of the organ frame 403 indicated by the second pupil 513. The X coordinate 514 and the Y coordinate 515 are the coordinates of the vertex at the upper left of the screen of the organ frame 403.

  The width 516 is the width of the pupil organ frame 403 indicated by the second pupil 513. The height 517 is the height of the pupil organ frame 403 indicated by the second pupil 513.

  In addition, data relating to the face such as the orientation of the face and the position of other organs is recorded in the database.

  FIG. 6 shows a flowchart of a live view (LV) shooting mode in the digital camera 100. This processing is realized by expanding the program recorded in the nonvolatile memory 56 into the system memory 52 and executing the program by the system control unit 50.

  In the present process, when the system control unit 50 displays a face frame on an image in the LV shooting mode or the playback mode, the process of FIG. 6 is started by triggering that the user touches down the touch bar 82. . The display of the face frame is, for example, that the user touches the face of the subject using the touch panel 70a, and that the system control unit 50 recognizes the face of the subject using the image processing unit 24 and displays the face frame on an arbitrary face. And so on. Further, a method of displaying a face frame on a subject by performing a tap other than a right tap and a left tap on the touch bar 82 may be adopted.

  The description of the flowchart will be described with reference to FIG. FIG. 7 is a diagram illustrating an example of a display screen of the digital camera 100. When the flowchart is started, the display unit 28 is in the state of FIG. However, since FIG. 7 shows the display unit 28 and the touch bar 82 in a simplified manner for explanation, the size relationship between the display unit 28 and the touch bar 82 is not accurate.

  First, a case where the user performs a slide operation (touch move) on the touch bar 82 will be described.

  In step S601, the system control unit 50 determines whether the operation performed on the touch bar 82 is a touch move. If it is determined that the touch move is performed, the system control unit 50 performs the process of step S602. If it is determined that the touch move is not performed, the system control unit 50 performs the process of step S607.

  In step S602, the system control unit 50 transitions to the touch move state. The touch move state is a state in which the system control unit 50 recognizes a touch move (slide operation) and does not recognize a tap operation because the user is performing a slide operation by the touch move. If it is already in the touch move state, the system control unit 50 need not perform the process of this step.

  In step S603, the system control unit 50 determines whether the touch-move direction is leftward or rightward. If the touch-move direction is the left direction, the system control unit 50 performs the process of step S604. When the touch-move direction is the right direction, the system control unit 50 performs the process of step S605.

  In step S604, when the system control unit 50 detects a rightward slide on the touch bar 82, the system control unit 50 changes the screen from the currently selected face to the state shown in FIG. The face frame 701 is moved to the face existing on the right side toward. For example, in one slide to the right, the system control unit 50 assigns a face area that is equal to or larger than the X coordinate of the currently selected face area and that has the closest X coordinate to the currently selected face area. The face frame 701 is superimposed. If the face does not exist on the right side of the screen with respect to the currently selected face area, the system control unit 50 performs processing for not moving the face frame 701 or sets the face frame 701 to the face area where the X coordinate of the face area is the smallest. Is performed.

  In step S605, when the system control unit 50 detects a leftward slide on the touch bar 82, the system control unit 50 moves the face frame 701 from the currently selected face to a face present on the left side of the screen. For example, in one slide to the left, the system control unit 50 sets the face area having the X coordinate equal to or less than the X coordinate of the currently selected face area and closest to the currently selected face area to the face area. The face frame 701 is superimposed. If no face is present on the left side of the screen with respect to the currently selected face area, the system control unit 50 performs processing for not moving the face frame 701 or sets the face frame 701 to the face area having the largest X coordinate of the face area. Is performed.

  In step S606, the system control unit 50 determines whether a touch-up has been performed. If it is determined that the touch-up has not been performed, the system control unit 50 returns to the process of step S601 and continues the touch-move state. If it is determined that the touch-up has been performed, the system control unit 50 ends the processing.

  So far, the processing of the system control unit 50 when the user performs the slide operation has been described. Hereinafter, the processing of the system control unit 50 when the user does not perform the slide operation (NO in step S601) will be described.

  In step S607, the system control unit 50 determines whether or not it is in the touch move state. If the state is the touch move state, the system control unit 50 determines that the state is the touch move state, and performs the process of step S606. If it is not in the touch move state, the system control unit 50 determines that it is not in the touch move state, and performs the process of step S608.

  In step S608, the system control unit 50 determines whether a touch-up has been performed. If it is determined that the touch-up has been performed, the system control unit 50 performs the process of step S609. If it is determined that the touch-up has not been performed, the system control unit 50 returns to the process of step S601 and continues to wait for a user operation.

  In step S609, the system control unit 50 determines the position where the touch-up on the touch bar 82 is detected. If it is determined that the touch-up has been performed (right tap) on the right key top portion 82R (the touch sensor electrode 302c), the system control unit 50 performs the process of step S610. When it is determined that the touch-up has been performed (left tap) on the key top left portion 82L (the touch sensor electrode 302a), the system control unit 50 performs the process of step S611. If it is determined that the touch-up has been performed on the other (the touch sensor electrode 302b), the system control unit 50 performs the process of step S612.

  If the organ frame 702 is not displayed in step S610, as shown in FIG. 7B, the system control unit 50 selects the pupil existing on the right side of the screen, and ends the processing. For example, the system control unit 50 compares the X coordinates of the first pupil and the second pupil recorded in the database, and superimposes the organ frame 702 on the pupil having the larger X coordinate. When the organ frame 702 is already displayed, the system control unit 50 performs a process of superimposing the organ frame 702 on the other pupil or a process of deleting the organ frame 702 from the screen.

  If the organ frame 702 is not displayed in step S611, the system control unit 50 selects a pupil existing on the left side of the screen and ends the processing. For example, the system control unit 50 compares the X coordinates of the first pupil and the second pupil recorded in the database, and superimposes the organ frame 702 on the pupil having the smaller X coordinate. When the organ frame 702 is already displayed, the system control unit 50 performs a process of superimposing the organ frame 702 on the other pupil or a process of deleting the organ frame 702 from the screen.

  In step S612, the system control unit 50 determines whether or not the organ frame 702 is displayed on the display unit 28. When the organ frame 702 is displayed, the system control unit 50 performs the process of step S613. When the organ frame 702 is not displayed, the system control unit 50 performs the process of step S614.

  In step S613, the system control unit 50 performs a process of deleting the organ frame 702 from the screen, and ends the process.

  In step S610, the system control unit 50 performs a process of deleting the face frame 701 from the screen, and ends the process.

  In this flowchart, the user can select a face by a slide operation and a pupil by a tap operation. The processes of the tap operation and the slide operation may be interchanged. That is, the user may be able to select a pupil by a slide operation and a face by a tap operation.

  In step S608, the system control unit 50 may determine whether a predetermined time has elapsed after determining whether the touch-up has been performed. If the predetermined time has elapsed, the system control unit 50 may determine that the user does not intend to perform an operation using the touch bar 82 and end the process. For example, the predetermined time is defined as 10 seconds in the initial setting, so that the user can arbitrarily change it. If the predetermined time has not elapsed, the system control unit 50 performs a process according to the determination as to whether or not the touch-up has been performed.

  Further, FIG. 6 illustrates the case where the camera is shot with the camera held horizontally, but the same processing can be performed when the camera is shot with the camera held vertically. In this case, the system control unit 50 performs the processing with reference to the Y coordinate instead of the X coordinate of the face frame and the organ frame. For example, when the camera is held horizontally in step S610 in FIG. 6, the system control unit 50 compares the Y coordinates of the first pupil and the second pupil recorded in the database, and uses the smaller Y coordinate. An organ frame 702 is superimposed on a certain pupil.

  In the present embodiment, the touch bar 82 has been described as a member different from the touch panel 70a, but the touch bar 82 may be displayed as a GUI on the touch panel 70a and replaced. When a touch bar is displayed as this GUI, the GUI of the touch bar may be set not to be displayed when the touch bar operation is invalid. When the GUI bar is displayed on the grip section 90 side (at the point where the right thumb can reach) as shown in FIG. can get. The touch bar in FIG. 8A is one example. By doing so, it is possible to select a target face or pupil by using the touch bar as a GUI member on the touch panel.

  8A shows a state in which a face is selected, FIG. 8B shows a state in which a pupil is selected, FIG. 8C shows a face selected in FIG. 8A, or FIG. It is a screen display example in which the selection was moved to the face on the right side by sliding the touch bar to the right from the pupil selection state. FIG. 8D shows a state in which the face bar is not selected and the touch bar is not displayed. The touch bar is displayed on the touch panel as close to the grip as possible. Further, the touch bar is arranged so as not to overlap the face reflected on the display unit 28.
