The system control unit 214 starts operations such as AF processing, AE processing, AWB processing, and EF processing in response to the first shutter switch signal SW1.
The second shutter switch 227 is turned on when the operation of the shutter button 101 is completed, so-called full-pressing (imaging instruction), and generates the second shutter switch signal SW2. By the second shutter switch signal SW2, the system control unit 214 starts a series of photographing processing operations from signal reading from the image pickup unit 213 to writing image data in the recording medium 230.

The operation unit 228 is various operation members as an input unit that receives an operation from a user.

When the touchdown is detected, it is also detected that the touch is on. After touchdown, touchon is normally detected unless touchup is detected. A touch move is also detected when touch-on is detected. Even if the touch-on is detected, the touch move is not detected unless the touch position moves. After it is detected that all the touched fingers or pens have touched up, the touch is turned off.

The system control unit 214 is notified of the above-described operation/state and the coordinates of the finger or pen touching the touch panel 229 through the internal bus. The system control unit 214 determines what operation is performed on the touch panel 229 based on the notified information. Regarding the touch move, the system control unit 214 can determine the moving direction of the finger or pen moving on the touch panel 229 for each vertical component/horizontal component on the touch panel 229 based on the change in the coordinates. In addition, it is assumed that a stroke is drawn when the touch panel 229 is touched down, touched up through a certain touch move, and then touched up. The operation to draw a stroke quickly is called flick. The flick is an operation in which a finger is quickly touched on the touch panel 229, quickly moved by a certain distance, and then released, in other words, an operation of quickly tracing the touch panel 229 with a finger. The system control unit 214 detects that a touch move has been performed for a predetermined distance or more at a predetermined speed or more, and if the touch-up is detected as it is, it is determined that the flick is performed. Further, the system control unit 214 determines that the drag is performed when it is detected that the touch move is performed at a predetermined distance or more and less than the predetermined speed.

The digital camera 100 also includes a power supply control unit 231, a power supply unit 232, a recording medium I/F 233, a communication unit 234, a posture detection unit 235, and an eyepiece detection unit 115. The power supply control unit 231 includes a battery detection circuit, a DC-DC converter, a switch circuit that switches blocks to be energized, and the like, and detects whether or not the battery is mounted, the type of battery, and the remaining battery level. Further, the power supply control unit 231 controls the DC-DC converter based on the detection result and the instruction of the system control unit 214, and supplies a necessary voltage to each unit including the recording medium 230 for a necessary period. The power supply unit 232 includes a primary battery such as an alkaline battery or a lithium battery, a secondary battery such as a NiCd battery, a NiMH battery, a Li battery, an AC adapter, or the like.

The communication unit 234 can also be connected to a wireless LAN (Local Area Network) or the Internet. The posture detection unit 235 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 235, the system control unit 214 determines whether the image photographed by the image pickup unit 213 is the image photographed with the digital camera 100 horizontally or vertically. It is possible to discriminate whether or not it is an image. The system control unit 214 can add orientation information corresponding to the orientation detected by the orientation detection unit 235 to the image data captured by the imaging unit 213, or can rotate and store the image. .. An acceleration sensor, a gyro sensor, or the like can be used as the attitude detection unit 235.

The eyepiece detection unit 115 is arranged around the finder 114. The eyepiece detection unit 115 of the present embodiment detects whether or not the user's face is close to the finder 114, specifically, the distance from the finder 114 to the user's face. The eyepiece detection unit 115 can use, for example, an infrared proximity sensor and can detect the approach of any object to the finder 114. When an object approaches, the infrared light projected from the light projecting unit (not shown) of the eyepiece detection unit 115 is reflected and received by the light receiving unit (not shown) of the infrared proximity sensor. The distance from the eyepiece portion to the object (eyepiece distance) can also be determined by the amount of infrared rays received. In this way, the eyepiece detection unit 115 performs eyepiece detection for detecting the proximity distance of the object to the finder 114. When an object approaching the finder 114 within a predetermined distance is detected in the non-eyepiece state, it is assumed that the eyepiece is detected. It is assumed that it is detected that the object has been detached from the eye contact state when the object whose approach has been detected is separated by a predetermined distance or more. The threshold value for detecting eye contact and the threshold value for detecting eye contact may be different, for example, by providing hysteresis. Further, after detecting the eyepiece, the eyepiece state is assumed until the eyepiece is detected. After detecting the eye separation, it is assumed that the eye is not in the eye contact state until the eye contact is detected. Note that the infrared proximity sensor is an example, and the eyepiece detection unit 115 may employ another sensor as long as it can detect the approach that can be regarded as the eyepiece of the user.
The eyepiece detection unit 115 notifies the system control unit 214 of the detected information, and the system control unit 214 controls the effective range of the touch panel 229 based on the information detected by the eyepiece detection unit 115 so that the viewfinder 114 is contacted with the eye. The operability of can be improved.
Hereinafter, a process in which the system control unit 214 specifically controls the effective range of the touch panel 229 will be described.

Here, the operation of the digital camera 100 will be described with reference to the flowchart of FIG. The process of the flowchart in FIG. 3 is realized by expanding the program stored in the non-volatile memory 223 into the system memory 224 and executing it by the system control unit 214.
In step S300, the system control unit 214 turns on the power of the digital camera 100 via the power control unit 231 in response to the operation of turning on the power switch 106.
In S301, the system control unit 214 sets the effective range of the touch operation on the touch panel 229 on the entire surface of the touch panel 229. By setting the effective range of the touch panel 229 on the entire surface, the system control unit 214 can detect the touch operation of the user on the entire surface of the touch panel 229.

In S302, the system control unit 214 sets the control of the touch operation on the touch panel 229 to the control based on the absolute position. The control based on the absolute position is a control in which a touch position (touch coordinates) on the touch panel 229 and a display coordinate of the in-finder display unit 220 are uniquely associated with each other. Further, the control based on the relative position is a control that does not uniquely associate the touch position (touch coordinates) on the touch panel 229 and the display coordinates (instruction coordinates) of the in-finder display unit 220, and the moving direction of the touch position. And the designated coordinates in the viewfinder display section 220 are relatively moved according to the movement amount. Details of the control based on the absolute position and the control based on the relative position will be described later.
In S303, the system control unit 214 acquires the information detected by the eyepiece detection unit 115. Here, the eyepiece detection unit 115 outputs the output value S corresponding to the distance of the object close to the finder 114, specifically, the distance from the finder 114 to the user's face. That is, the system control unit 214 acquires the output value S from the eyepiece detection unit 115.
It should be noted that the output value S of the present embodiment is output as a smaller value as the distance to the object to be detected is longer, and as a larger value as the distance to the object is shorter.

In S304, the system control unit 214 determines whether the acquired output value S is greater than or equal to the first threshold value. Here, the first threshold value corresponds to a distance that is close to the finder 114 such that it is difficult for the user to grasp the entire display content when the display unit 105 is visually recognized. The first threshold can be calculated empirically or experimentally, and is stored in the nonvolatile memory 223 in advance. Here, the distance corresponding to the first threshold is L1.
When the output value S is smaller than the first threshold value, that is, when the user's face is more than the distance L1, the process returns to S303, and the system control unit 214 acquires the output value S again and becomes equal to or larger than the first threshold value. Continue processing until. Therefore, the effective range of the touch panel 229 remains the state of the entire surface set in S301. On the other hand, if the output value S is greater than or equal to the first threshold, that is, if the user's face is less than or equal to the distance L1, the process proceeds to S305.

In step S<b>305, the system control unit 214 performs control such that the display unit 105 is hidden and the brightness of the backlight of the display unit 105 is reduced. Here, when the output value S is equal to or larger than the first threshold value and the process proceeds to S305, it means that the face of the user is so close to the finder 114 that it is difficult to grasp the entire display content of the display unit 105. .. Therefore, it can be estimated that the user does not intend to confirm the display content of the display unit 105, and in S305, the system control unit 214 controls the display unit 105 in order to reduce power consumption and prevent glare. In the following description, it is assumed that the display unit 105 is hidden.
Here, FIG. 4 is a conceptual diagram showing the relationship between the position of the user's face, the effective range of the touch panel, and the display state of the display unit 105.
FIG. 4A is a conceptual diagram when the output value S is less than the first threshold value, that is, when the user's face is more than the distance L1. In FIG. 4A, the effective range of the touch panel 229 is set on the entire surface, and the live view image is displayed on the display unit 105, for example.
FIG. 4B is a conceptual diagram when the output value S is greater than or equal to the first threshold value, that is, when the user's face is less than or equal to the distance L1. In FIG. 4B, the effective range of the touch panel 229 is continuously set to the entire surface, and the display unit 105 is hidden.

In S306, the system control unit 214 changes the operation mode by the touch operation.
Specifically, the system control unit 214 changes the operation mode so that one or a plurality of settings related to shooting that can be set by touch operation cannot be set.
Here, FIGS. 5A to 5D are examples of settings that the user can perform by touch operation when the output value S is less than the first threshold value, that is, when the user's face is more than the distance L1. FIG. 5A to 5D are screens of aperture value setting, shutter speed setting, exposure setting, and ISO sensitivity setting, which are displayed on the display unit 105. Here, the user can perform all the settings displayed on the display unit 105 by touch operation.

FIGS. 6A and 6B show examples of settings that the user can perform by touch operation even when the output value S is greater than or equal to the first threshold, that is, when the user's face is less than or equal to the distance L1. It is a figure. FIGS. 6A and 6B are screens for setting focus detection points and selection frames, which are displayed on the in-finder display unit 220, respectively. The user can perform a setting to move the focus detection point 601 and a setting to move the selection frame 602 for selecting the detected face by a touch operation via the touch panel 229. On the other hand, the user cannot set the aperture value, shutter speed, exposure, and ISO sensitivity as described above. Here, examples of the restricted settings include settings that cannot be displayed on the in-finder display section 220 because an optical system finder is used for the finder 114. The setting information that is limited when the output value S is equal to or larger than the first threshold value is stored in the non-volatile memory 223. Therefore, the system control unit 214 limits the setting based on the stored information. However, the system control unit 214 may be configured to be able to restrict the setting based on the registered setting information by arbitrarily registering the setting information restricted by the user.

In addition, the system control unit 214 changes the operation mode so that the movement distance when moving the display item by the touch operation is different. Here, a case where a touch move of a distance m is detected as a touch operation for moving the distance measuring point 601 shown in FIG. 6A will be described as an example. When the output value S is less than the first threshold value, the system control unit 214 causes the distance measuring point 601 to select the distance measuring point 603 from the distance measuring point 601 when the touch move of the distance m is detected. On the other hand, when the output value S is greater than or equal to the first threshold value, the system control unit 214 causes the distance measuring point 601 to select the distance measuring point 604 that is 2t even if the touch move of the same distance m is detected.
In this way, the system control unit 214 changes the operation mode so that the movement distance for moving the display item is increased even when the same distance is detected by the touch operation. Therefore, even when the user's face is close to the display unit 105 and it is difficult to move the finger on the touch panel 229, the operability of the touch operation can be improved by increasing the moving distance of the display item.

In S307, the system control unit 214 changes the control based on the touch operation. Specifically, the system control unit 214 changes the control based on the touch operation from the control based on the absolute position (hereinafter, absolute position control) to the control based on the relative position (hereinafter, relative position control).
Hereinafter, the absolute position control and the relative position control will be described with reference to FIGS. 7A and 7B by taking a touch operation for moving the position of the focus detection point as an example.
FIG. 7A is a diagram showing an example of absolute position control. Here, FIG. 7A (a) shows the in-finder display section 220, and FIG. 7A (b) shows a touch operation on the touch panel 229.
First, it is assumed that the distance measuring point 701 in FIG. 7A(a) has been selected. Next, it is assumed that the user touches down on touch panel 229 with finger 702 as shown in FIG. 7A(b). In this case, the system control unit 214 acquires the coordinates of the finger 702 touched down from the touch panel 229, and displays it so as to select the distance measuring point 703 in FIG. 7A(a), which is the position corresponding to the acquired coordinates. As described above, in the absolute position control, the distance measuring point 703 moves to the corresponding touch position based on the touched-down touch position. That is, the process (movement of the distance measuring point 703) corresponding to the touch position when the start of the touch is detected is performed. Next, it is assumed that the user touch-moves from the position touched down on the touch panel 229 to the finger 704 as shown in FIG. 7A(b). In this case, the system control unit 214 acquires the coordinates of the finger 704 from the touch panel 229, and displays so as to select the distance measuring point 705 in FIG. 7A(a), which is the position corresponding to the acquired coordinates.
Therefore, the absolute position control refers to control for performing processing that reflects the coordinates of the touch operation on the touch panel 229.

FIG. 7B is a diagram showing an example of relative position control. Here, FIG. 7B(a) shows the in-finder display section 220, and FIG. 7B(b) shows a touch operation on the touch panel 229.
First, it is assumed that the distance measuring point 706 in FIG. 7B(a) has been selected. Next, it is assumed that the user touches down on touch panel 229 with finger 707 as shown in FIG. 7B(b). Here, the coordinate position of the finger 707 in FIG. 7B(b) is the same as the coordinate position of the finger 702 in FIG. 7A(b), but the system control unit 214 determines the distance measurement point as shown in FIG. 7B(a). Keep 706 selected. That is, in the relative position control, the distance measuring point 703 does not move just by touching down. Next, it is assumed that the user touch-moves from the position touched down on the touch panel 229 to the finger 708 as shown in FIG. 7B(b). In this case, the system control unit 214 uses the touched-down position as a reference point to display the distance measuring point 709 shown in FIG. 7B(a) corresponding to the direction and the distance from the finger 707 to the finger 708 so as to be selected. As described above, in the relative position control, the processing based on the moving direction and the moving distance of the touch position is performed regardless of the touch position when the start of the touch is detected.
Therefore, the relative position control refers to control for acquiring the direction and the distance (at least the direction) of the touch operation on the touch panel 229 and performing the process in which the acquired direction and the distance (at least the direction) are reflected.

Here, when the output value S is greater than or equal to the first threshold, it is assumed that the user's face is close to the display unit 105 and it is difficult for the user to perform a touch operation while confirming the position of the touch panel 229. It Therefore, by changing from the absolute position control to the relative position control, the user does not need to confirm the position of the touch panel 229, and thus the operability when the user's face contacts the finder 114 can be improved.
Even if the same distance is detected by the touch operation in S306, the operation mode is changed so that the movement distance for moving the display item is increased. Therefore, although the distance from the finger 707 to the finger 708 in FIG. 7B(b) is shorter than the distance from the finger 702 to the finger 704 in FIG. 7A(b), both of FIGS. 7A(a) and 7B(a). The distance from the distance measuring point before being selected to the distance measuring point after being selected is the same.

In S308, the system control unit 214 again acquires the information detected by the eyepiece detection unit 115, that is, the output value S.
In S309, the system control unit 214 determines the distance to the finder 114 to the user's face based on the output value S. When the output value S is less than the first threshold value, that is, when the user's face is more than the distance L1, the process proceeds to S310.
In S310, the system control unit 214 causes the display unit 105 to be displayed again or the brightness to be increased to restore the original display state. Further, the system control unit 214 changes (returns) the control based on the touch operation from the relative position control to the absolute position control. Here, the case where the user's face is farther than the distance L1 means that the user can grasp the entire display content of the display unit 105. Therefore, the system control unit 214 restores the display state of the display unit 105 so that the user can check the display unit 105. Further, the system control unit 214 sets the effective range of the touch operation on the touch panel 229 on the entire surface of the touch panel 229. Then, the process returns to S303.

In S309, when the output value S is greater than or equal to the first threshold value and less than the second threshold value (first threshold value<second threshold value), that is, the user's face is less than or equal to the distance L1 and the distance L2 (distance L1>distance L2). If the distance is greater than ), the process proceeds to S311. Here, the distance corresponding to the second threshold is L2.
In S311, the system control unit 214 sets the effective range of the touch operation on the touch panel 229 to a range a smaller than the entire surface. The system control unit 214 stores the position of the set effective range in the system memory 224. FIG. 4C is a conceptual diagram when the output value S is greater than or equal to the first threshold value and less than the second threshold value, and the effective range of the touch panel 229 is set to a range a smaller than the entire surface. In the range a, a slight range on one side (left side) of the touch panel 229 is missing as compared with the case of the entire surface. The position information of the range a is stored in the non-volatile memory 223 in advance. It returns to S308 after the process of S311.

If the output value S is greater than or equal to the second threshold value and less than the third threshold value (second threshold value<third threshold value) in S309, that is, the user's face is less than or equal to the distance L2 and the distance L3 (distance L2>distance L3). If the distance is larger than ), the process proceeds to S312. Here, the distance corresponding to the third threshold value is L3.
In S312, the system control unit 214 sets the effective range of the touch operation on the touch panel 229 to a range b smaller than the range a. The system control unit 214 stores the position of the set effective range in the system memory 224. FIG. 4D is a conceptual diagram when the output value S is greater than or equal to the second threshold value and less than the third threshold value, and the effective range of the touch panel 229 is set to the range b smaller than the range a. In the range b, a part of one side (left side) of the touch panel 229 is missing from the range a. The position information of the range b is stored in the nonvolatile memory 223 in advance. In the relative position control, the movement ratio of the designated position (the designated position of the distance measuring point, the display position of the designated index on the in-finder display section 220) with respect to the movement of the touch position is set to the effective range of the touch operation in the range a. It may be larger than the case (S311). It progresses to S314 after the process of S312.

In S309, when the output value S is greater than or equal to the third threshold value and less than the fourth threshold value (third threshold value <fourth threshold value), that is, the user's face is less than or equal to the distance L3 and the distance L4 (distance L3> distance L4). If the distance is greater than ), the process proceeds to S313. Here, the distance corresponding to the fourth threshold value is L4.
In S313, the system control unit 214 sets the effective range of the touch operation on the touch panel 229 to a range c smaller than the range b. The system control unit 214 stores the position of the set effective range in the system memory 224. FIG. 4E is a conceptual diagram when the output value S is equal to or larger than the third threshold value and smaller than the Xth threshold value, and the effective range of the touch panel 229 is set to a range c smaller than the range b. In the range c, one side (left side) of the touch panel 229 is largely missing as compared with the range b. The position information of the range c is stored in the non-volatile memory 223 in advance. Note that, in the relative position control, the movement ratio of the designated position (the designated position of the distance measuring point, the display position of the designated index on the in-finder display section 220) with respect to the movement of the touch position is set to the range b of the effective range of the touch operation. It may be larger than the case (S313). It progresses to S314 after the process of S313.
The area of the above-mentioned effective range has a relationship of range a> range b> range c. Further, in this embodiment, the area is increased or decreased by moving one side (left side) of the rectangular effective range, and the other side (right side) is fixed.

As described above, the system control unit 214 increases the area of the touch operation effective range of the touch panel 229 as the distance from the finder 114 to the user's face increases, and decreases the touch operation effective range of the touch panel 229 as the distance decreases. Control stepwise so that In other words, when the distance from the finder 114 to the user's face is the second distance that is shorter than the first distance, the system control unit 214 sets the effective range of the touch operation to the second range that is smaller than the first range. Control to.

In step S<b>314, the system control unit 214 detects that the user's face is not in contact but is in close proximity, that is, the hover is detected via the touch panel 229. Here, the case of proceeding to S<b>314 means that the system control unit 214 is so close to the display unit 105 that the hover can be detected by targeting the user's face via the touch panel 229. Here, in the case of S312 and S313, that is, when the output value S is equal to or larger than the second threshold value, the process proceeds to S314, and thus the second threshold value corresponds to a distance at which the hover can be detected via the touch panel 229.
In step S315, the system control unit 214 acquires the hover position, that is, the proximity position of the user's face from the touch panel 229.

In step S316, the system control unit 214 sets the invalid range of the touch operation on the touch panel 229 according to the acquired proximity position, thereby resetting the valid range.
In the conceptual diagram of FIG. 4D (when the output value S is greater than or equal to the second threshold and less than the third threshold), the hover is detected on one side (left side) of the touch panel 229, and the elliptical invalid range X is detected. Is set. Here, the invalid range X has advanced to a part of the range b indicating the valid range. Therefore, the system control unit 214 resets the effective range from the rectangular effective range b to a range in which a part of the rectangular shape is cut out in a circular shape.
In the conceptual diagram of FIG. 4E (when the output value S is greater than or equal to the third threshold value and less than the Xth threshold value), a hover is detected on one side (slightly left side of the center) of the touch panel 229, and the ellipse shape is detected. The invalid range Y is set. Here, a large elliptical ineffective range Y extends into a part of the range c indicating the effective range. Therefore, the system control unit 214 resets the effective range to the range of the rectangular effective range c in which a part of the rectangular shape is largely cut out in a circular shape.
In this way, the system control unit 214 resets the initially set effective range. The system control unit 214 stores the re-set effective range position in the system memory 224. It should be noted that the method of resetting the effective range is not limited to the case where a part of the rectangular shape is cut out into a circular shape, and the effective range may be reduced to a rectangular shape so as not to include the elliptical invalid range. Good. Specifically, as shown in FIG. 4(e), the system control unit 214 keeps the effective range in a rectangular shape so that the left side (dotted line) of the effective range is located at the end Z of the ellipse of the ineffective range Y. Can be reconfigured to be smaller.

After that, the process returns to S308, and the system control unit 214 continues the process until the photographing mode is changed or the power switch is turned off. At this time, when the touch operation on the touch panel 229 is detected, the system control unit 214 determines whether or not it is within the effective range based on the position of the effective range stored in the system memory 224, and touches the effective range. If it is an operation, the process is executed according to the touch operation. On the other hand, when the touch operation is outside the valid range, the system control unit 214 does not execute the process according to the touch operation and invalidates the touch operation.

In S311 to S313 described above, one side (left side) of the rectangular effective range of the touch panel 229 is moved to increase or decrease the area, but the user looks into the finder 114 with the left eye. The position of the effective range may be changed depending on whether the right eye or the right eye.
FIG. 8 is a diagram showing an example of the position of the effective range corresponding to the eye looking into the finder.
As shown in FIG. 8A, when the eye looking through the finder 114 is the right eye, the left side of the rectangular effective range of the touch panel 229 is moved to increase or decrease the area.
As shown in FIG. 8B, when the eye looking into the finder 114 is the left eye, the right side of the rectangular effective range of the touch panel 229 is moved to increase or decrease the area.

Here, a method in which the system control unit 214 determines whether the eye looking into the finder 114 is the right eye or the left eye will be described.
First, as a first method, a method of making a determination based on information input by a user will be described. FIG. 9A is a diagram showing an example of a guidance display for prompting the user to input in advance the eyes looking into the finder 114. The system control unit 214, for example, displays a guidance on the display unit 105 when the power is turned on, allows the user to select either the right eye or the left eye, and stores information on the selected eye in the non-volatile memory 223. Therefore, when setting the effective range to the ranges a to c, the system control unit 214 changes the positions of the ranges a to c based on the eye information stored in the nonvolatile memory 223. The information of the eye looking into the finder 114 may be set again from the menu of the setting screen, or may be stored and set in the nonvolatile memory 223 for each of a plurality of users. When the setting is performed for each of a plurality of users, the system control unit 214 can read the eye information according to the user by the user selecting the setting at the time of shooting or selecting the user to use.

In addition, as a second method, a method using hover detection via the touch panel 229 will be described.
FIG. 9B is a diagram showing an example of a position where the hover is detected via the touch panel 229 when the finder 114 is looked into with the right eye. In FIG. 9B, since the system control unit 214 detects the hover at the position 901 on the left side of the touch panel 229 by the user's nose, when the hover is detected on the left side, the eye looking through the finder 114 is the right eye. It can be determined that there is.
FIG. 9C is a diagram showing an example of a position where the hover is detected via the touch panel 229 when the finder 114 is viewed with the left eye. In FIG. 9C, since the system control unit 214 detects the hover at the position 902 on the right side of the touch panel 229 by the user's cheek, when the hover is detected on the right side, the eye looking into the finder 114 is the left eye. It can be determined that there is.

Further, as a third method, a method using a biosensor will be described.
As shown in FIG. 9A, a biosensor 903 capable of detecting whether the eye looking through the finder 114 is the right eye or the left eye is provided in the finder 114. Therefore, the system control unit 214 can determine whether the eye looking through the finder 114 is the right eye or the left eye based on the information detected by the biometric sensor 903.

As described above, according to the present embodiment, when the distance from the finder 114 to the user's face is long, it is unlikely that the user's face touches the touch panel 229. Therefore, the touch operation on the touch panel 229 is effective. Increase the range. Therefore, for a user who looks into the finder 114 while keeping a part of the face from touching, it is possible to improve the operability when the finder 114 is in the eye.
On the other hand, when the distance from the finder 114 to the user's face is short, there is a high possibility that the user's face will unintentionally touch the touch panel 229, so the effective range of the touch operation on the touch panel 229 is reduced. Therefore, it is possible to prevent a malfunction of the touch operation caused by a part of the face touching the touch panel 229.
Further, according to the present embodiment, the effective range of the touch operation of the touch panel 229 is changed according to the distance from the finder 114 to the user's face, so that the effective range according to the possibility of the user's face touching is changed. It is set, and more erroneous touch operations can be prevented. At this time, since the effective range is changed stepwise, the processing by the system control unit 214 can be reduced.

Further, according to the present embodiment, the position where a part of the user's face actually approaches is determined by detecting the proximity of an object using the touch panel 229, that is, the hover, and the touch panel 229 of the touch panel 229 is determined based on the approached position. Set the invalid range. Therefore, the position where a part of the user's face approaches the touch panel 229 can be accurately determined and the invalid range can be set, so that the malfunction of the touch operation can be accurately prevented.
In the above-described embodiment, the case where the hover is uniformly detected via S312 or S313 when the output value S from the eyepiece detection unit 115 is equal to or larger than the second threshold value has been described, but the present invention is not limited to this case. Absent. When the output value Sn acquired from the eyepiece detection unit 115 has changed from the output value S(n-1) acquired last time, the system control unit 214 specifically changes the output value Sn to the previous output value S(n-1). It may be configured to detect the hover when it changes from the threshold value range. For example, when the previous output value S(n-1) is greater than or equal to the first threshold value and less than the second threshold value, the system control unit 214 causes hover when the current output value Sn is greater than or equal to the second threshold value and less than the third threshold value. If the detected output value Sn is also the first threshold value or more and less than the second threshold value, the hover is not detected. When the output value S changes so as to cross the threshold value in this way, it can be assumed that the distance from the touch panel 229 to the user's face is changing, and the hover detected at this time is the user's face. Is likely to be. On the other hand, when the output value S does not change, it can be assumed that the distance from the touch panel 229 to the user's face has not changed, and the hover detected at this time is not the user's face but a touch operation. Is likely to be.
Therefore, by detecting the hover only when the output value S changes so as to cross the threshold value, the system control unit 214 can set the invalid range based on the position where a part of the user's face approaches, and the touch operation can be performed. Based on this, it is possible to prevent the invalid range from being set by mistake.

Further, in the above-described embodiment, the case where the threshold value to be compared with the output value S is the first threshold value to the fourth threshold value has been described, but the present invention is not limited to this case, and the threshold value may have any number of stages.
Further, in the above-described embodiment, the case where the effective range of the touch panel 229 is the range a to the range c has been described, but the present invention is not limited to this case, and the range may be any number of stages.
Further, in the above-described embodiment, the output value S is described as being smaller as the distance from the finder 114 to the user's face is larger and larger as the distance is closer, but the present invention is not limited to this case. That is, the output value S may increase as the distance from the finder 114 to the user's face increases, and decrease as the distance decreases.

Further, in the above-described embodiment, the case where the hover is detected via S312 or S313 when the output value S from the eyepiece detection unit 115 is equal to or larger than the second threshold value has been described, but the present invention is not limited to this case. Hover may be detected even if the threshold value is.
Further, in the above-described embodiment, the case where the hover is detected in order to reset the effective range has been described, but the process of detecting the hover may be omitted. That is, S314 to S316 in the flowchart of FIG. 3 may be omitted, and even in this case, it is possible to prevent a malfunction of the touch operation caused by a part of the face touching the touch panel 229.

The above-described various controls described as being performed by the system control unit 214 may be performed by one piece of hardware, or a plurality of pieces of hardware may share the processing to control the entire apparatus. ..
Further, although the present invention has been described in detail based on its preferred embodiments, the present invention is not limited to the above-described embodiments, and various forms within the scope of the present invention are also included in the present invention. ..
