When considering that the AF frame is selected by touching the touch panel as in Patent Document 1, the AF frame selected by the user is directly touched and selected from among the plurality of AF frames displayed on the touch panel. A method is conceivable. In this case, since the index is displayed at the touched position, the finger position and the AF frame may overlap, making it difficult to know which position of the frame was selected. Therefore, when the index is displayed at a position deviated from the touched position as described in Patent Document 2, it is not possible to know exactly which position of the frame is actually selected, and the frame is considered to be selected by the user. There is a possibility that the frame actually selected will be out of alignment.

In view of the above problems, it is an object of the present invention to show the position selected by the user more accurately and in an easy-to-understand manner when selecting a position by a touch operation on a touch panel integrated with a display unit.

In order to achieve the above object, the display control device of the present invention includes a touch detecting means for detecting a touch on the display means and a designating means for designating a designated target in a predetermined area of the display means according to the touch position. A second axis, in which the target designated by the designated means based on the touch position of the touch becomes the intersection of the first axis and the first axis in response to the touch to the predetermined area. It is a display control means that identifies and displays within the predetermined area so as to indicate an axis and controls so that the identification display is hidden when the touch is released, and the display control means moves to the predetermined area. In response to the start of the touch, a display indicating a designated target according to the position where the touch is started is displayed, and before the predetermined time elapses after the touch to the predetermined area is started, When the touch is released from the position where the touch is started, the identification display is not performed, and the identification display is performed according to the elapse of the predetermined time after the touch to the predetermined area is started. It is characterized by having a display control means which is characterized by controlling so as to perform the above .

According to the present invention, when a position is selected by a touch operation on a touch panel integrated with a display unit, the position selected by the user can be shown more accurately and easily.

The modes included in the still image recording mode include an auto shooting mode, an auto scene discrimination mode, a manual mode, various scene modes for shooting settings for each shooting scene, a program AE mode, a custom mode, and the like. The mode changeover switch 60 directly switches to any of these modes included in the menu screen. Alternatively, after switching to the menu screen once with the mode changeover switch 60, the mode may be switched to any of these modes included in the menu screen by using another operation member. Similarly, the moving image shooting mode may include a plurality of modes.

The first shutter switch 62 is turned on by a so-called half-press (shooting preparation instruction) during the operation of the shutter button 61 provided on the digital camera 100, and the first shutter switch signal SW1 is generated. AF (autofocus) processing, AE (autoexposure) processing, AWB (auto white balance) processing, EF (flash pre-flash) processing for a position or area preset by the user by the first shutter switch signal SW1. And so on. At this time, if the position for performing each process is not set in advance by the user, the process may be performed at a position such as the center position of the imaging range, the position where the face of a person is detected, or the position where the subject is detected. Good.

The second shutter switch 64 is turned on when the operation of the shutter button 61 is completed, so-called full pressing (shooting instruction), and the second shutter switch signal SW2 is generated. The system control unit 50 starts a series of shooting processing operations from the still image imaging operation by the imaging unit 22 and the signal reading from the imaging unit 22 to the writing of the image data to the recording medium 200 by the second shutter switch signal SW2. ..

Each operation member of the operation unit 70 is assigned a function as appropriate for each scene by selecting and operating various function icons displayed on the display unit 28, and acts as various function buttons. Examples of the function button include an end button, a back button, an image feed button, a jump button, a narrowing down button, an attribute change button, and the like.

As one of the operation units 70, the touch panel 70a capable of detecting contact with the display unit 28 (touch detection) is provided. The touch panel 70a and the display unit 28 can be integrally configured. For example, the touch panel 70a is configured so that the light transmittance does not interfere with the display of the display unit 28, and is attached to the upper layer of the display surface of the display unit 28. Then, the input coordinates on the touch panel are associated with the display coordinates on the display unit 28. As a result, it is possible to configure a GUI (graphical user interface) as if the user can directly operate the screen displayed on the display unit 28. The system control unit 50 performs the following operations on the touch panel 70a. Alternatively, the state can be detected.
-A finger or pen that was not touching the touch panel has newly touched the touch panel. That is, the start of touch (hereinafter referred to as touch-down).
-The touch panel must be touched with a finger or a pen (hereinafter referred to as touch-on).
-Move while touching the touch panel with a finger or pen (hereinafter referred to as Touch-Move).
-Release the finger or pen that was touching the touch panel. That is, the end of touch (hereinafter referred to as touch-up (Touch-Up)).
-A state in which nothing is touched on the touch panel (hereinafter referred to as touch-off).

When a touchdown is detected, it is also detected that it is touch-on. After touchdown, touch-on usually continues to be detected unless touch-up is detected. Touch move is also detected when touch on is detected. Even if touch-on is detected, touch move is not detected unless the touch position is moved. After it is detected that all the fingers and pens that have been touched are touched up, the touch is turned off. These operations / states and the position coordinates of the finger or pen touching on the touch panel are notified to the system control unit 50 through the internal bus, and the system control unit 50 what kind of information is displayed on the touch panel based on the notified information. Determine if the operation was performed. Regarding the touch move, the moving direction of the finger or pen moving on the touch panel can also be determined for each vertical component and horizontal component on the touch panel based on the change in the position coordinates. It is also assumed that a stroke is drawn when the touch panel is touched up from a touchdown through a certain touch move. The operation of drawing a stroke quickly is called flicking. Flicking is an operation in which a finger is quickly moved on the touch panel by a certain distance and then released as it is, in other words, it is an operation in which the touch panel is swiftly traced as if the finger is flicked. It can be determined that the flick has been performed when it is detected that the touch move is performed at a predetermined speed or more over a predetermined distance and the touch-up is detected as it is. Further, when it is detected that the touch move is performed at a speed equal to or less than a predetermined distance, it is determined that the drag has been performed. As the touch panel, any of various types of touch panels such as a resistive film method, a capacitance method, a surface acoustic wave method, an infrared method, an electromagnetic induction method, an image recognition method, and an optical sensor method may be used. .. Depending on the method, there is a method that detects that there is a touch due to contact with the touch panel, and a method that detects that there is a touch even if the finger or pen is close to the touch panel but does not touch it. Method may be used.

Next, the AF AF point selection process in the present embodiment will be described with reference to FIG. The process of FIG. 3 starts when the power of the digital camera 100 is turned on, an item for changing the AF focusing point is selected on the menu screen, or the AF frame selection button 77 is pressed. Starts when the AF AF point selection screen is displayed. This process is realized by expanding the program recorded in the non-volatile memory 56 into the system memory 52 and executing it by the system control unit 50.

In S301, the system control unit 50 displays the AF AF point selection screen on the display unit 28. On the AF focus point selection screen 401 shown in FIG. 4A, it is possible to change the AF focus point selection pattern and select and set the AF focus point in the selected pattern. The number of frames displayed on the selection screen 401 is usually 61 points, but the user can set it to 47 points, 9 points, or the like (the number of frames that can be specified can be changed). The selection screen 401 has a predetermined area for selecting an AF AF point, and the predetermined area is an area in which a frame that can be selected as an AF AF point by the user in response to a touch operation is displayed, and the frame is displayed. It refers to the area from end to end in the vertical and horizontal directions. The area in which the icons 402 to 408, which will be described later, are displayed can also be selected according to the touch operation, but is not included in the predetermined area because it is not the AF focus point selection area. At this time, the set number of frames are displayed. Further, since the number of selectable frames (AF AF points) differs depending on the type of lens, the type of lens is determined and the frame to be displayed on the selection screen 401 is determined.

In S302, the system control unit 50 determines whether or not the selection pattern of the AF focusing point has been changed. The AF AF point selection pattern can be selected from the types shown by the icons 402 to 408 in FIG. 4A. Icon 402 indicates spot 1-point AF, and spot 1-point AF can focus on a narrow portion. The icon 403 indicates a one-point AF, and in the one-point AF, it is possible to focus on the position of one point selected from the frames displayed on the selection screen 401. The icon 404 indicates an optional area expansion AF, and in the optional area expansion AF, it is possible to focus on the selected one point and the position of the adjacent narrow AF frame in the vertical and horizontal directions. The icon 405 indicates the area expansion AF around the arbitrary selection, and the area expansion AF around the arbitrary selection can focus on the selected one point and the position of the adjacent peripheral AF frame. The icon 406 indicates zone AF. In zone AF, 61 AF frames can be divided into nine AF zones and focused in the selected AF zone. Icon 407 indicates large zone AF. In large zone AF, the AD area can be divided into three ranging zones, left, center, and right, and the focus can be adjusted in the selected zone. The icon 408 indicates automatic selection AF, and in automatic selection AF, it is possible to focus on the entire area of a frame of 61 points. The AF focus point selection pattern can be changed by touching the icon, pressing the AF frame selection button 77, or rotating the main electronic dial 71. The rotation operation to the main electronic dial 71 can be switched by assigning the function of switching the AF AF point selection pattern to the rotation of the main electronic dial 71. If it is determined that the AF AF point selection pattern has been changed, the process proceeds to S303, and if not, the process proceeds to S304.

In S303, the system control unit 50 acquires the selection pattern selected in S302 and records it in the non-volatile memory 56.

In S304, the system control unit 50 displays the cursor at the selected AF point (area). The cursor 409 in FIG. 4A indicates the AF point selected in the spot 1-point AF.

In S305, the system control unit 50 determines whether or not the frame has been touched (within a predetermined area). If it is determined that the touch operation has been performed, the process proceeds to S306, and if not, the process proceeds to S314.

In S306, the system control unit 50 determines whether or not the current selection pattern is zone selection (a pattern of a large type of selection target including large zone selection). If it is determined that the zone is selected, the process proceeds to S307, and if not, the process proceeds to S310.

In S307, the system control unit 50 displays the cursor 415 in the area of the touched AF point as shown in FIG. 4 (g). FIG. 4 (g) shows a display example in the case of zone selection, and displays the cursor 415 in the touched area among the nine ranging zones.

In S308, the system control unit 50 sets the touched ranging zone as the ranging area and records it in the system memory 52.

In S309, the system control unit 50 determines whether or not the touch is released. If it is determined that the touch has been released, the process proceeds to S317, and if not, the process returns to S307 and the ranging area is set according to the touch position. However, if the touch position does not move and the touch remains, the processing in S307 and S308 may not be performed. FIG. 4 (h) shows the selection screen 401 after the touch is released from the state of FIG. 4 (g), and the display does not change from the time of FIG. 4 (g).

In S310, the system control unit 50 displays vertical and horizontal lines passing through the touched-down frame (area) (indicating a position where one point is selected). 4 (a) to 4 (c) show an example of the spot 1-point AF, and FIGS. 4 (d) to 4 (f) show an example of the selection screen 401 at the time of the area expansion AF around the arbitrary selection. Further, FIGS. 4 (b) and 4 (e) show an example of the selection screen 401 during touch. In the case of spot 1-point AF, as shown in FIG. 4B, the vertical line 411 (Y-axis direction) and the horizontal line 410 (X-axis direction) passing through the touched frame are selected from the frame selected by touch. Extend to the area where the AF point is displayed. That is, the touched point is displayed so as to be the intersection of the two lines. As a result, the user can more accurately grasp the position of the touched frame even if the touched frame cannot be seen by the touched finger. It is also effective when the touched finger spans multiple frames and it is difficult to know which one is selected. At this time, the vertical line 411 and the horizontal line 410 may be displayed so as to extend from one end to the other of the X-axis coordinate and the Y-axis coordinate of the setting screen, or three or two adjacent to the touched frame. The display may be extended by a number of frames. Further, in the case of area expansion AF, as shown in FIG. 4 (e), in addition to the vertical line 414a and the horizontal line 413a indicating the touched frame, the vertical line having a width passing through the frame around the touched frame. The thick line 414 and the horizontal thick line 413 are displayed. At this time, the vertical line 414a is located in the center of the vertical thick line 414, and is displayed in a dark color so as to be distinguishable from the vertical thick line 414. Similarly, the horizontal line 413a is displayed so as to be distinguishable from the thick horizontal line 413, indicating which frame was touched, that is, which frame was selected as the AF area. At this time, each thick line is displayed so as to indicate the frame selected by touching and the left and right or upper and lower frames so that the eight points (8 frames) around the touched point (frame) can be known. , You can also see the size of the selected area. By changing the method of identification display in this way, the size of the selected selection target can be known. However, if the touched frame is located in the end row of the frames included in the selection screen 401, the number of surrounding frames is not eight, and AF distance measurement adjacent to the touched frame A thick line is displayed to indicate the frame that can be set as a point. In this way, when selecting an AF AF point by touch operation, the finger performing the selection operation and the selected frame overlap, but by displaying the frame position with a line, the user can use the finger under the finger. You can know exactly which frame you are selecting. In the example of FIG. 4B, the frame being touched is the fourth frame from the bottom from the horizontal line 410 to the right end of the central area (fifth from the right of the whole). Can be seen from the vertical line 411. Further, as described above, a position designation pattern in which only the frame at the touch position such as spot 1-point AF and 1-point AF is targeted for AF, and a surrounding frame adjacent to the touch position such as area expansion AF are AF targets. The display differs depending on the area specification pattern. In the case of the position specification pattern, the frame of the touch position is identified and displayed so that the frame of the touch position can be identified, and in the case of the area specification pattern, in addition to the specified touch position, the surrounding frame to be AF can be identified. Draw a line for the book.

In S311 the system control unit 50 sets (designates) the touched frame (frame area) as an AF AF point (area) and records it in the system memory 52. That is, the AF position is specified based on the touch position.

In S312, the system control unit 50 determines whether or not the touch detected in S305 has been released. If it is determined that the touch is released, the process proceeds to S317, and if not, the process returns to S310.

In S313, the system control unit 50 displays the cursor at the AF focusing point (area) set in S311 immediately before. FIG. 4C shows the selection screen 401 in which the touch is released from the state in which the frame was touched in FIG. 4B, and the cursor 409 is displayed on the frame touched by the user. .. Further, FIG. 4 (f) shows a selection screen 401 in which the cursor 412 is displayed on the touched frame in response to the touch being released from the frame touched in FIG. 4 (e). .. In this way, when the selected pattern is not zone AF, the vertical and horizontal lines that were displayed when the camera was touched are hidden, and the touched AF measurement that is set as the AF focus point. The cursor 412 indicating the distance point (area) is displayed.

In S314, the system control unit 50 determines whether or not any of the main electronic dial 71, the sub electronic dial 73, the multi-controller 76, and the cross key 74 has been operated. That is, it is determined whether or not the AF AF point has been changed by an operation (designated operation) on an operation member other than the touch panel 70a. However, when the switching of the selection pattern is assigned to the rotation of the main electronic dial 71, the determination of the main electronic dial is not performed in S314. The main electronic dial 71 can move the cursor in the horizontal direction, the sub electronic dial 73 can move the cursor in the vertical direction, the multi-controller 76 can move the cursor according to the operation direction, and the cross key 74 can move the cursor in each direction. .. As the cursor moves, the selected frame is set as the AF AF point. If it is determined that any of the main electronic dial 71, sub electronic dial 73, multi-controller 76, and cross key 74 has been operated, the process proceeds to S315, and if it is determined that no operation has been performed on any of them. , Proceed to S317.

In S315, the system control unit 50 displays the cursor at the AF point at the position according to the operation direction. The AF AF point selected on the selection screen 401 of FIG. 4A moves, for example, when the operation of moving upward is performed, the cursor 409 moves to the position of the frame one level higher and moves to the right. When the move operation is performed, the cursor 409 moves to the position of the frame to the right by one. Further, also in the case of the area expansion AF shown in FIG. 4D, the AF focusing point moves according to the operation direction. The main electronic dial 71 is instructed to move in the left-right direction, and the sub electronic dial 73 is instructed to move in the up-down direction. Rotation of each member in the right direction causes rotation in the right (down) direction and left direction. Suppose that it moves to the left (up). However, in the case of zone AF, both operating members move in the left-right direction. When the AF AF point is changed by operating an operation member other than the touch panel 70a, the cursor is moved and displayed, and the line or thick line indicating the selected frame is not displayed. When selecting an AF focus point by operating an operation member other than touch operation, the finger to be operated and the selected frame do not overlap, so a line is displayed as when operating by touch operation. Even if you don't have it, you can see which frame is selected by displaying the cursor. Also, if you display a line that indicates the selected frame even though the cursor and the finger that performs the selection operation do not overlap, it becomes difficult to tell whether the entire line indicated by the line was selected or which part was selected. It ends up. Therefore, when selecting a frame by operating an operation member other than the touch panel 70a, the user can clearly know which frame is selected by displaying the cursor.

In S316, the system control unit 50 sets the selected frame (frame area) as the AF focusing point (area) and records it in the system memory 52.

In S317, the system control unit 50 determines whether or not a shooting instruction has been given. The shooting instruction can be given by pressing the shutter button 61. If it is determined that the shooting instruction has been given, the process proceeds to S318, and if not, the process proceeds to S319.

In S318, the system control unit 50 performs AF (autofocus, automatic focusing) on the AF point set in any of S308, S311, and S316, and records the captured image on the recording medium 200.

According to the embodiment described above, when selecting a frame on the selection screen by touch operation on the touch panel integrated with the display unit, it is accurate without degrading the visibility of which frame the user has selected. Can be shown to the user. In the case of touch operation, the selected frame is hidden under the finger that performed the selection operation, so it is intuitive that the midpoint of the line is selected by displaying two lines indicating the selected position. Can be grasped. On the other hand, when operating with an operating member other than the touch panel, the finger performing the selection operation and the selected frame do not overlap, so that the selected frame can be accurately indicated to the user by displaying the cursor.

In the present embodiment, it has been described that the AF AF point is selected from the single AF points, but if there is a frame capable of cross distance measurement depending on the type of lens, a frame capable of cross distance measurement is possible. The frame that is not and the frame that is not are shown in different display forms. Frames that cannot be cross-distanced are displayed in a blinking manner, and frames that can be cross-distanced are displayed without blinking. In addition to the blinking display, the color expression and the thickness of the display line may be changed. In addition, when a frame capable of cross distance measurement is touched by touch operation, a thicker line is displayed than when a frame capable of single distance measurement is touched. In this way, the display form of the line may be changed according to the nature of the selected point.

Further, if an operation is performed on each operation member other than the touch panel during the operation on the touch panel 70a, the frame selection by the touch operation is invalid, and the selection (cursor movement) by each operation member other than the touch panel is prioritized. To. At this time, the cursor is displayed in the selected frame, and the line passing through the frame is not displayed. However, if it is determined that there is a selected frame under the finger performing the touch operation by selecting a frame other than the touch operation, a line is displayed to indicate the position of the frame. Good.

[Modification example]
Next, an example to which the above-described embodiment can be applied will be described with reference to FIGS. 5 (a) to 5 (d) and FIGS. 6 (a) to 6 (b).

A display example when selecting a subject to be AF (autofocus) processed on a live view image (through image) will be described with reference to FIGS. 5A to 5D. In the selection of the subject on the live view, it is possible to select an arbitrary position on the live view instead of selecting one of a plurality of predetermined AF frames as in the example of FIG. In FIGS. 5 (a) to 5 (d), the image 501 is shown on the display unit 28 integrated with the touch panel 70a. In (a) to (b), small flowers are shown, and (c) to (d) are shown. Shows how the user is selecting a person's face. FIG. 5A shows a state in which the user touches the subject 506 with a finger. At this time, the subject 506 is hidden by the finger touching the subject 506 (flower), so that the horizontal line 502 And the vertical line 503 are displayed. When the touch is released, as shown in FIG. 5B, the AF frame 504 indicating the subject to be AF is displayed, and the horizontal line 502 and the vertical line 503 are hidden. When the subject is selected according to the operating member other than the touch panel 70a, the line is not represented and the AF frame is moved. Further, as shown in FIG. 5C, when the subject 507 (larger than the subject 506) detected by the face detection process and whose size is known is touched, the subject 507 is the face. Since it has already been detected, the line is not displayed even in the touched state, and the AF frame 505 is displayed. The AF frame 505 is displayed based on the size of the face detected by the face detection process. At this time, as shown in FIG. 5D, the AF frame 505 remains displayed even after the touch is released. In this way, when the subject touched by the user is smaller than the predetermined size that can be hidden by the finger, the subject touched by the line is shown without displaying the AF frame, and the touched subject can be grasped than the predetermined size. If it is larger than the fingertip, the AF frame is displayed without displaying the line. The size of the subject touched by the user is detected by the subject detection unit that detects the subject information from the image acquired from the image pickup unit. When a shooting instruction is given, the AF frame 505 or the subject indicated by the line is focused and shot.

As described above, according to the modification described with reference to FIGS. 5A to 5D, the user can more accurately grasp which position the subject is selected regardless of the size of the touched subject (object). can do.

If you display the AF frame at a position slightly away from the actual selected subject so that it does not overlap with the touching finger, the selected part is the touched part or the AF frame is displayed. Partial or user can be confused. Further, if the AF frame is displayed larger than the actually selected subject to indicate the subject, it becomes difficult to understand which subject in the AF frame is selected. Therefore, as described above, the position of the selected subject can be confirmed more accurately by deciding whether to display the AF frame or to show it with a line according to whether the touched subject is larger or smaller than the predetermined size. The line color may be changed or the display form may be changed according to the selected subject.

Next, a display example when setting the white balance will be described with reference to FIGS. 6A to 6B. FIG. 6A shows a selection screen 601 for setting a white balance shift, where A is amber, B is blue, G is green, and M is magenta. The closer to the side where A, B, G, and M are described, the more each color shifts. The horizontal axis from B to A determines the color temperature, and the vertical axis from M to G can adjust the color correction different from the color temperature.

As shown in FIG. 6A, when a touch is made on the scale of the selection screen 601, a horizontal line 603 and a vertical line 602 indicating the scale position of the touched position are displayed. At this time, the horizontal line 603 is shown in colors using magenta and green according to the Y coordinate of the touched position, and the vertical line 602 is shown in colors using blue and amber corresponding to the X coordinate of the touched position. You may. In the case of FIG. 6A, the horizontal line 603 is shown in a color closer to magenta, and the vertical line 602 is shown in a color closer to amber. FIG. 6B shows the display after the touch is released, and the mark 604 indicating the position of the selected scale is displayed. When the white balance is set by an operation member other than the touch panel 70a, it is indicated by a mark 604.

As described above, according to the modification described with reference to FIGS. 6A to 6B, the user can accurately grasp the position of the touched scale. In addition, it is possible to intuitively grasp what kind of index the touched scale indicates by the color of the line.

According to each of the above-described embodiments, when selecting a desired position (set value) displayed on the display unit 28 in response to a touch operation on the display unit 28, it is accurate which position (set value) is selected. Can be grasped. Further, the present invention is not limited to each of the above-described embodiments, and can be applied to the selection of coordinates, the selection of cells in a table, the selection of numerical values on a bar (one line), and the like.

In each of the above-described embodiments, the lines indicating the touched frame are shown in the horizontal direction and the vertical direction (90 degrees different from the horizontal line and orthogonal to each other), but the touch points are not limited to this. It may be indicated by a line of a book. Further, although it has been explained that the line is displayed so as to pass through the touched frame, as shown in FIGS. 7A and 7B, the identification display may be performed at a nearby position without passing through the selected frame. .. 7 (a) and 7 (b) show a display example showing the touched frame, and in FIG. 7 (a), the frame adjacent to the touched frame is identified and displayed (identification display 701) instead of the line. .. In this way, even if the line does not pass through the touched frame, the identification display may be used so that the touched position can be accurately identified. That is, the frames in the same row and column as the touched frame in the area displayed in the matrix are identified and displayed. In FIG. 7B, a line (line 702) that does not pass through the touched frame but passes through the adjacent frame is displayed. Further, when the selection pattern is the area expansion AF, the line passing through the frame adjacent to the set area or the frame may be identified and displayed instead of the frame adjacent to the touched frame. By displaying the identified frame (line display or position highlighting) indicating the touched frame at a position close to the touched frame (within a certain distance), the user can accurately grasp which is selected. Can be done. Even if the identification is displayed at a position far from the touched frame, the distance between the position where the identification is displayed and the actual touch is increased. Therefore, the user must virtually follow the straight line from the position of the two points displaying the identification to the touch position and grasp the point where the lines intersect, and the point that the user is touching intuitively and accurately It's hard to grasp.

If the number of selectable frames is small, this process may not be performed. For example, if the number of frames remains 61 points, a line indicating the touch points is displayed, and if there are few selection candidates such as less than 30 points, the user is unlikely to be confused as to which position to touch. The touched frame may be identified and displayed without displaying the line. Further, when a screen with a small number of items is displayed, this process may not be performed.

Furthermore, it was explained that the line is hidden according to the release of the touch and the frame that was touched is identified and displayed, but it is displayed as a line until a predetermined time such as 1 second or 2 seconds elapses after the touch is released. And the display may be switched according to the elapse of a predetermined time (line non-display). Further, the touched frame may be identified and displayed before the touch is released.

A mouse can also be applied as an operating member other than the touch panel. In the case of a mouse, the cursor is displayed, but since the cursor can indicate which frame is selected, it is not necessary to display a line.

[Example 2]
Next, the AF AF point selection process in the second embodiment of the present embodiment will be described with reference to FIG. The second embodiment is the same as that of the first embodiment except for the flowchart of FIG. 3 described above. The second embodiment is different from the AF focus detection point selection process of the first embodiment in that vertical and horizontal lines are displayed when a predetermined time or more has elapsed after the touch to the focus detection point is started. The process of FIG. 8 starts when the power of the digital camera 100 is turned on, an item for changing the AF focusing point is selected on the menu screen, or the AF frame selection button 77 is pressed. Starts when the AF AF point selection screen is displayed. This process is realized by expanding the program recorded in the non-volatile memory 56 into the system memory 52 and executing it by the system control unit 50.

The processes of S801 to S805 are the same as the processes of S301 to S305 of FIG.

In S806, the system control unit 50 starts measuring the touch time T. The touch time T is a time indicating how long the touch detected in S805 has been touching since the start of the touch. The touch time T is measured by the system timer in the system control unit 50.

The processes of S807 to S810 are the same as the processes of S306 to S309 of FIG.

In S811, the system control unit 50 determines whether or not the touch time T at which the measurement was started in S806 has elapsed by a predetermined time or more. The predetermined time is a value such as 1.5 seconds, 1 second, or 2 seconds. If it is determined that the touch time T has elapsed more than a predetermined time, the process proceeds to S812, and if not, the process proceeds to S813.

In S812, the system control unit 50 displays vertical and horizontal lines passing through the touched-down frame (area) (indicating a position where one point is selected), similarly to S310 in FIG. When it is determined in S811 that the touch time T has elapsed more than a predetermined time, the process proceeds to S812 and vertical and horizontal lines are displayed, so that the user can more accurately grasp the position of the touched frame. In the second embodiment, if it is determined that the predetermined time or more has passed in S811, yes, the vertical and horizontal lines are displayed, and if it is determined as No, the vertical and horizontal lines are not displayed. Therefore, when the user decides the frame to be touched, aims to touch the frame, and quickly releases the touch (less than a predetermined time), the vertical and horizontal lines are not displayed. After deciding the frame to be selected by the user and performing the touch operation quickly, the cursor is immediately displayed on the touched frame in S816 (same as the process of S313 in FIG. 3) described later. Therefore, it is unlikely that the frame touched by the user is accurately grasped, and the cursor is displayed immediately even if the user does not accurately grasp the position. In addition, it is possible to prevent the line displayed momentarily from flickering when the user touches the frame quickly. Even when it is determined in S814 that will be described later that the touch move has been performed Yes, vertical and horizontal lines are displayed in S812. If the vertical and horizontal lines have already been displayed, the vertical and horizontal lines are not newly displayed in S812.

In S813, the system control unit 50 sets (designates) the touched frame (frame area) as the AF focusing point (area) and records it in the system memory 52, similarly to S311 in FIG.

In S814, the system control unit 50 determines whether or not the touch position has been moved. The movement of the touch position determines whether or not the touch position has moved from the touch position detected in S805 or the touch position in S312 one cycle before. If it is determined that the touch position has been moved, the process proceeds to S812, and if not, the process proceeds to S815. In S811 described above, when the touch time exceeds a predetermined time, vertical and horizontal lines are displayed in S812, but when it is determined in S814 that the touch position has moved, even if the touch time is less than the predetermined time. Display vertical and horizontal lines. That is, the vertical and horizontal lines passing through the touched point are displayed even if the touch is made at the same position for a predetermined time or more after the touch is started, or if the touch is started for less than a predetermined time. This is the case when the touch position is moved. When the touch position is moved, the frame at the position where the touch is started and the frame currently being touched are different even if it is less than a predetermined time, so that the user can accurately grasp the position of the frame being touched. It may not be. Therefore, when the touch position moves in S814, the process proceeds to S812 and a line is displayed.

The processing of S815 to S821 is the same as the processing of S312 to S318 in FIG.

According to the embodiment described above, when selecting a frame on the selection screen by touch operation on the touch panel integrated with the display unit, it is accurate without degrading the visibility of which frame the user has selected. Can be shown to the user. In addition, when the user touches quickly, the vertical and horizontal lines are not displayed, so that flicker can be prevented.

It should be noted that the above-mentioned various controls described as being performed by the system control unit 50 may be performed by one hardware, or the entire device may be controlled by sharing the processing among a plurality of hardware. ..
