As described above, the camera 100 has, as one of the operation units 70, the touch panel 70a capable of detecting contact with the display unit 28 (touch panel 70a). The touch panel 70a and the display section 28 can be configured integrally. For example, the touch panel 70 a is configured so that the light transmittance does not interfere with the display of the display section 28 and is attached to the upper layer of the display surface of the display section 28 . Then, the input coordinates on the touch panel 70a and the display coordinates on the display unit 28 are associated with each other. This makes it possible to construct 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 touch operations or states on the touch panel 70a.
- A finger or pen that has not touched the touch panel 70a newly touches the touch panel 70a. That is, the start of touch (hereinafter referred to as Touch-Down).
- The touch panel 70a is in a state of being touched with a finger or a pen (hereinafter referred to as Touch-On).

When touchdown is detected, touchon is also detected at the same time. After touchdown, touchon continues to be detected unless touchup is detected. A touch-move is also detected when a touch-on is detected. Even if touch-on is detected, touch-move is not detected if the touch position does not move. After it is detected that all the fingers and pens that have touched have touched up, the touch is turned off.

The system control unit 50 is notified of these operations/states and the coordinates of the position where the finger or pen touches the touch panel 70a through the internal bus. Determine if any operation has been performed. As for the touch move, the moving direction of the finger or pen moving on the touch panel 70a can also be determined for each vertical component/horizontal component on the touch panel 70a based on the change in the position coordinates. Also, it is assumed that a stroke is drawn when touch-down on the touch panel 70a is touch-up after a certain touch-move. The operation of drawing strokes quickly is called a flick. A flick is an operation of quickly moving a finger a certain distance while touching the touch panel 70a and then releasing the finger, in other words, an operation of quickly tracing the touch panel 70a with the finger as if flicking. It is possible to determine that a flick has been performed when it is detected that a touch-move has been performed for a predetermined distance or more at a predetermined speed or more, and if a touch-up is detected as it is. Further, when it is detected that the touch-move is performed over a predetermined distance at a speed lower than the predetermined speed, it is determined that the drag is performed. The touch panel 70a may be any one of various types of touch panels such as a resistive film type, a capacitance type, a surface acoustic wave type, an infrared type, an electromagnetic induction type, an image recognition type, an optical sensor type, and the like. good.

Furthermore, based on the output information of the AF-ON buttons 1 and 2, the system control unit 50 determines the amount of movement of the finger or the like on the AF-ON buttons 1 and 2 ( hereinafter referred to as a movement amount (x, y)). The system control unit 50 can also detect the following operations or states of the AF-ON buttons 1 and 2. The system control unit 50 individually calculates the movement direction and movement amount (x, y) for each of the AF-ON button 1 and the AF-ON button 2, and detects the following operations/states.
・A finger that was not touching AF-ON button 1 or AF-ON button 2 has newly touched AF-ON button 1 or AF-ON button 2. That is, the start of touch (hereinafter referred to as Touch-Down).
・A state where the AF-ON button 1 or AF-ON button 2 is being touched with a finger or the like (hereinafter referred to as Touch-On).
- A finger or the like is moving while touching the AF-ON button 1 or AF-ON button 2 (hereinafter referred to as touch-move).
・The finger that was touching AF-ON button 1 or AF-ON button 2 has been removed from AF-ON button 1 or AF-ON button 2. That is, the end of the touch (hereinafter referred to as Touch-Up).
A state in which the AF-ON button 1 or AF-ON button 2 is not touched (hereinafter referred to as Touch-Off).

When touchdown is detected, touchon is also detected at the same time. After touchdown, touchon continues to be detected unless touchup is detected. A touch-move is also detected when a touch-on is detected. Even if touch-on is detected, if the amount of movement (x, y) is 0, touch-move is not detected. After it is detected that all the fingers that have been in touch have touched up, the touch is turned off.

The system control unit 50 determines what operation (touch operation) has been performed on the AF-ON buttons 1 and 2 based on these operations/states, movement direction, and movement amount (x, y). As for touch-move, the movement of a finger on the AF-ON buttons 1 and 2 can be performed in eight directions: up, down, left, right, upper left, lower left, upper right, lower right, or in the x-axis and y-axis directions. Detect movement in two-dimensional directions. The system control unit 50 determines that a slide operation has been performed when movement in any one of the eight directions or movement in one or both of the two-dimensional directions of the x-axis direction and the y-axis direction is detected. It shall be. In this embodiment, the AF-ON buttons 1 and 2 are infrared touch sensors. However, a touch sensor of another system such as a resistive film system, a surface acoustic wave system, a capacitive system, an electromagnetic induction system, an image recognition system, an optical sensor system, or the like may be used.

The light emitted from the light projecting unit 312 is desirably non-visible light (infrared light). When the finger 300 is touching the surface of the window 311 (the operation surface of the AF-ON button 1), the light emitted from the light projecting unit 312 is reflected on the surface of the finger 300 that is touching. Light is received (imaged) by the light receiving unit 313 . The light receiving unit 313 is an imaging sensor. Based on the image captured by the light receiving unit 313, the operation body (finger 300) is placed on the operation surface of the AF-ON button 1.
It is possible to detect whether the is not touching, whether the operating body has touched, whether the touching operating body is moving while touching (is performing a slide operation), and the like. The cover 310 is installed on a ground surface 316 with an elastic member 314, and when the finger 300 presses the surface of the window 311 and the cover 310 is pushed, the cover 310 touches a switch 315 for detecting pushing. This detects that the AF-ON button 1 has been pressed.

The face detection function will be explained. The system control unit 50 sends an image for face detection to the image processing unit 24 . Under the control of the system control unit 50, the image processing unit 24 applies a horizontal bandpass filter to the image data. Also, under the control of the system controller 50, the image processor 24 applies a vertical bandpass filter to the processed image data. Edge components are detected from the image data by these horizontal and vertical bandpass filters.

After that, the system control unit 50 performs pattern matching on the detected edge components to extract a group of candidates for eyes, nose, mouth, and ears. Then, the system control unit 50 determines eye pairs that satisfy preset conditions (for example, the distance and inclination of the two eyes) from the group of extracted eye candidates. Only those that have are narrowed down as the candidate group of eyes. Then, the system control unit 50 associates the group of narrowed-down eye candidates with the corresponding other parts (nose, mouth, ears) forming the face, and passes them through a preset non-face condition filter. , to detect faces. The system control unit 50 outputs the face information according to the face detection result, and ends the process. At this time, the feature quantity such as the number of faces is stored in the system memory 52 .

As described above, it is possible to perform image analysis of the LV image or the image to be reproduced and displayed, extract the feature amount of the image, and detect subject information (perform subject detection for detecting a specific subject). In the present embodiment, a face is taken as an example of a specific subject, but other subjects such as eyes, hands, torso, specific individuals, moving bodies, characters, etc. can also be detected and selected as targets for AF or the like. be.

FIG. 3A is a schematic diagram showing a state in which a finger 300 is touching the operation surface of the AF-ON button 1, but the AF-ON button 1 is not pressed. FIG. 3B is an outline of a state in which the finger 300 presses the operation surface of the AF-ON button 1, thereby pressing the AF-ON button 1 and detecting that the AF-ON button 1 has been pressed. It is a diagram. When the finger 300 is removed from the operation surface of the AF-ON button 1 from the pressed state shown in FIG. return to state. Although an example in which the elastic member 314 is installed on the ground surface 316 has been described, the elastic member 314 may be installed on the outer cover 301 instead of the ground surface 316 . Also, the AF-ON button 1 is limited to the structure shown in FIGS. 3(a) and 3(b) as long as it can detect the pressing of the operation surface and the touch operation on the operation surface. Instead, other structures may be used.

AF frames selectable in the OVF mode will be described. In the OVF mode, the user can select and set one of a plurality of selection modes including at least the following selection modes in advance from a setting menu as the AF frame selection mode (distance measurement area selection mode).
・One-point AF (arbitrary selection): A selection mode in which the user selects one AF point to be used for focusing (AF) from 191 AF points (focusing areas). A range narrower than zone AF, which will be described later, is the focus adjustment area.
• Zone AF (optional zone selection): A selection mode in which a plurality of focus detection points are classified into nine focus detection zones (focus adjustment areas) and the user selects one of the focus detection zones. Automatic selection AF is performed using all distance measuring points included in the selected zone. In automatic selection AF, AF is performed so that a subject determined as a subject to be automatically focused among the subjects whose distances are measured at the target distance measuring point is brought into focus. Basically, AF is performed so that the subject at the closest distance is brought into focus, but conditions such as the position on the screen, the size of the subject, and the subject distance may be taken into account. It is easier to capture the subject than single-point AF, and it is easier to focus when shooting a moving subject. In addition, since the zone to be focused is narrowed down, it is possible to prevent the subject from being brought into focus at an unintended position in the composition.
• Automatic selection AF: A mode in which the above-described automatic selection AF is performed using all distance measuring points. The range-finding points used for AF are automatically determined from all range-finding points without the user having to select an AF area.

Focus points selectable in single-point AF will be described with reference to FIGS. 4(a) and 4(b). FIG. 4(a) is a display example of selectable range-finding points and selected range-finding points in the viewfinder display section 41. FIG. The user can select any one point from the range-finding point group 410 . The selected focus point is displayed as an AF frame 400. FIG. The AF frame 400 is actually visually superimposed on the optical image of the subject. Among the group of ranging points 410, ranging points that have not been selected may not be displayed. The focus detection unit 11 is capable of focus detection and AF at positions corresponding to the positions of the distance measurement points included in the distance measurement point group 410 . The ranging point group 410 is classified into a left ranging point group 411 , a center ranging point group 412 and a right ranging point group 413 . In each of the left ranging point group 411 and the right ranging point group 413, 63 ranging points are arranged in a matrix of 9 rows and 7 columns. In the central focus point group 412, 65 focus points are arranged in a matrix of 13 rows and 5 columns. In single-point AF, a total of 191 ranging points included in the left ranging point group 411, the center ranging point group 412, and the right ranging point group 413 are selected as selection candidates, and any one point is used for AF. can be selected as FIG. 4A is a display example in which the focus detection point (central focus detection point) on the 7th row and the 3rd column included in the central focus point group 412 is selected as the AF frame 400 . FIG. 4B is a display example in which the range-finding point (central range-finding point) on the 6th row and the 4th column included in the central range-finding point group 412 is selected as the AF frame 400 . By moving the AF frame 400 once to the right from the state of FIG. 4(a) (a selection position moving amount=1, which will be described later, is referred to as one time) and once upward, the state of FIG. 4(b) is obtained. be able to. Also, the state shown in FIG. 4B can be obtained by moving the AF frame 400 once to the upper right from the state shown in FIG. 4A.

Focusing zones that can be selected in zone AF will be described with reference to FIGS. 5(a) to 5(i). 4(a) and 4(b) are denoted by the same reference numerals. In zone AF, it is possible to select one zone from the nine ranging zones shown in FIGS. 5(a) to 5(i) as selection candidates. FIG. 5A shows the central ranging zone of the focusing point group 410 (the zone including the ranging points on the 4th to 10th rows and the 1st to 5th columns included in the central ranging point group 412). is selected to display a zone AF frame 500. FIG.

FIG. 5(b) shows the upper range-finding zone (included in the central range-finding point group 412) in the range-finding point group 410 by moving the zone AF frame 500 upward once from the state of FIG. 5(a). This is an example of selecting a zone that includes the range-finding point groups of the 1st to 7th rows and 1st to 5th columns. Similarly, FIG. 5(c) is an example in which the zone AF frame 500 is moved downward once from the state of FIG. 5(a) to select the lower ranging zone. FIG. 5(d) is an example in which the zone AF frame 500 is moved to the left once from the state of FIG. 5(a) to select the left ranging zone. In FIG. 5E, the zone AF frame 500 is moved from the state of FIG. For example. In FIG. 5(f), the zone AF frame 500 is moved to the lower left once from the state of FIG. For example. FIG. 5(g) is an example in which the zone AF frame 500 is moved once to the right from the state of FIG. 5(a) to select the right ranging zone. In FIG. 5(h), the zone AF frame 500 is moved to the upper right once from the state of FIG. For example. In FIG. 5(i), the zone AF frame 500 is moved from the state in FIG. This is an example of

AF frames selectable in the LV mode will be described. In LV mode, the user can select and set one of a plurality of selection modes including at least the following selection modes in advance from the setting menu as the AF frame selection mode (focus area selection mode, AF method). can. Note that the LV mode is assumed to be in the moving image shooting standby state (moving image shooting mode) and during recording of the moving image.
・Face + tracking priority AF (face + tracking AF): If a face is detected from the LV image, the face is automatically tracked as an AF target and AF is performed, and if the face is not detected, automatic selection AF A selection mode in which the AF position is determined with and AF is performed. When a plurality of faces are detected from the LV image, an AF frame (face tracking frame) is displayed on the face determined by automatic selection at first, and the left and right of the eight direction keys 74a and 74b and the AF-ON button are displayed. You can switch the tracking target to the right or left face by operating. Also, by touching the display unit 28, it is possible to select a face or a subject (object) other than the face as a tracking target, track it, and adjust the AF.
・Live 1-point AF (arbitrary selection): A selection mode in which the user selects one AF point to be used for focusing (AF) from 5,655 AF points arranged in 65 rows and 87 columns. Focus detection and AF are performed with image plane phase difference AF or contrast AF for the selected distance measuring point.

Movement of the AF frame in live single-point AF will be described with reference to FIG. FIG. 6A is an example of display on the display unit 28 when live single-point AF is set in the LV mode. Various setting information, touch icons, and an AF frame 600 are displayed superimposed on the LV image 601 . The AF frame 600 is an indicator that indicates a selected position on the LV image, and can be moved according to a direction instruction operation with the 8-direction keys 74a and 74b and a slide operation to the AF-ON button. The AF frame 600 is relatively moved from the position before the movement by the amount obtained by multiplying the operation amount for each component in the x direction and the y direction of the operation to these operation members by a predetermined coefficient. Move to position.

Movement of the AF frame in face+tracking AF will be described with reference to FIG. 6(b). FIG. 6B is a display example on the display unit 28 when the LV mode is set to face+tracking AF, multiple faces are detected from the LV image, and one face is being tracked. is. Various setting information, touch icons, and an AF frame 610 (here, also a face frame, tracking frame, and face tracking frame) are displayed superimposed on the LV image 601 . Three faces, a face 621, a face 622, and a face 623, are detected from the LV image 601, and in the illustrated example, the face 621 is selected as an AF target and tracked. The AF frame 610 can be moved to another detected face in response to left and right direction instruction operations with the eight direction keys 74a and 74b and left and right slide operations on the AF-ON button. For example, in response to a movement instruction of a movement amount 1 (minimum unit movement amount) by a rightward sliding operation on the AF-ON button, a face on the right side of the currently selected face 621 before selection change is selected. The AF frame can be moved to the face closest to the inside face, that is, the face 622 . When the AF frame is moved to face 622, AF frame 610 is hidden and AF frame 610' is displayed. At this time, the AF frame moves from the face 621 before selection change to the face 622 without going through positions other than the face. The details of changing the face selection by sliding the AF-ON button for switching the selection in the horizontal direction will be described later.

FIG. 7 shows a flowchart of slide response processing for the AF-ON button. The slide response process is a process of executing a function (eg, moving the AF frame) in response to a slide operation of touching and moving the operation surface without pressing the AF-ON button. This process is realized by loading the program recorded in the nonvolatile memory 56 into the system memory 52 and executing it by the system control unit 50 . When the camera 100 is activated in shooting mode, the process of FIG. 7 is started. Note that when the camera 100 is activated in the shooting mode, other processing (for example, processing in response to operation of other operation members included in the operation unit 70, processing in response to pressing of the AF-ON button) is also performed in parallel. are performed, but the description thereof is omitted. 7 to 10, response processing to a slide operation for AF-ON button 1 will be described, but AF-ON button 2 is also processed in the same way. However, when a touch-on to the AF-ON button 1 is detected, slide response processing to the AF-ON button 2 is not performed. As a result, it is possible to prevent erroneous operation due to competing operations of the AF-ON button 1 and the AF-ON button 2 (the slide operation to the AF-ON button 1 has priority).

In S701, the system control unit 50 determines whether or not the AF-ON button 1 has been touched down. If there is a touchdown, the process proceeds to S703; otherwise, the process proceeds to S702. In the present embodiment, it is assumed that the processing after it is determined that there has been a touchdown is processing that is performed in a state where the depression of the AF-ON button 1 is not detected.

In S702, it is determined whether or not conditions for terminating the slide response process (for example, power off, transition to playback mode, etc.) are satisfied. If the termination condition is satisfied, the slide response process is terminated; otherwise, the process proceeds to S701 and repeats the process.

In S703, the system control unit 50 initializes various variables related to the slide operation. For example, the internal variable N is initialized with 0. This N indicates the number of times of sampling and is used when averaging the amount of movement. Every time N reaches 5, a moving amount obtained by averaging the moving amounts (touch-move amount, slide amount) obtained by sampling five times is acquired. Also, in S703, the system control unit 50 initializes the variable i to 0. This i indicates the number of acquisition times of the average movement amount after being touched. Also, the system control unit 50 initializes the variable Dsum to zero. Dsum is an integrated value of the moving distance (operation amount) in one slide operation in one or more acquisition periods (50 msec, which will be described later), and is a two-dimensional coordinate value having a directional component. As will be described later, Dsum is a variable that may be initialized even before a touchup is performed (i.e., during a touch) (i.e., the total integrated amount of touch movement distance after touchdown ).

In S704, the system control unit 50 performs Wait processing before reading out the detected value of the amount of movement from the AF-ON button 1. FIG. It is assumed that the Wait period is 10 msec (10 milliseconds).

In S705, the system control unit 50 acquires a detection value (a count value whose unit is not distance) Cx of the amount of movement in the X direction (horizontal direction) from the AF-ON button 1 . Similarly, in S706, the system control unit 50 acquires a detection value (a count value whose unit is not distance) Cy of the amount of movement in the Y direction (longitudinal direction) from the AF-ON button 1 .

In S707, the system control unit 50 stores the X-direction count value Cx acquired in S705 in the N-th Cxn[N] of the array Cxn. In S708, the system control unit 50 stores the Y-direction count value Cy obtained in S706 in the N-th Cyn[N] of the array Cyn. In S709, the system control unit 50 increments the variable N representing the number of times of sampling.

In S710, the system control unit 50 determines whether or not the AF-ON button 1 has been touched up. If the AF-ON button 1 is touched up, the process advances to S716; otherwise, that is, if the AF-ON button 1 is continuously touched, the process advances to S711.

In S711, the system control unit 50 determines whether or not the variable N is 5, that is, whether or not the number of times of sampling has reached 5 times. The case where N=5 is when 50 msec has passed since there was a touchdown if it is the first time, and when 50 msec has passed since the averaged movement amount was obtained last time if it is after the first time. . In this embodiment, the Wait time in S704 is 10 msec, and the movement of the AF frame with respect to the slide operation to the AF-ON button 1 is delayed enough for the user to recognize, that is, the response is poor. is not desirable, so N=5. That is, the acquisition frequency of the averaged distance is every 50 msec.

In S712, the system control unit 50 calculates the average value (Cxave) of the count values from Cxn[0] to Cxn[N-1] and the average value of the count values from Cyn[0] to Cyn[N-1]. (Cyave) is calculated.

In S713, the system control unit 50 converts the average count values Cxave and Cyave of the last five output values from the AF-ON button 1 into distances Xave and Yave in units of μm (micrometers). Specifically, Cxave and Cyave are respectively multiplied by predetermined coefficients to obtain Xave and Yave [μm]. By averaging and then converting to distance in this way, it is possible to prevent the amount of movement of the AF frame from becoming extremely unnatural with respect to the amount of movement of the actual finger due to the influence of noise, etc. are doing. Also, in S713, the system control unit 50 increments the variable i.

In S714, the system control unit 50 performs movement determination processing. The movement determination process will be described later using FIG.

In S715, the system control unit 50 initializes the variable N to 0, and then proceeds to S704 to perform sampling for the next acquisition of the averaged movement amount.

In S716, the system control unit 50 performs the same processing as in S712. A different point from S712 is that N is not always five. In S716, unlike S712, the variable N×10 msec, which is the averaged movement amount acquisition interval, may be shorter than 50 msec.

In S717, the system control unit 50 converts Cxave and Cyave into Xave and Yave [μm], and increments i in the same manner as in S713.

In S718, the system control unit 50 performs movement determination processing as in S714. The movement determination process will be described later using FIG.

FIG. 8 shows a flowchart of movement determination processing. This processing is the details of the processing of S714 and S718 in FIG. 7 described above. Also, this process is realized by loading the program recorded in the nonvolatile memory 56 into the system memory 52 and executing it by the system control unit 50 .

In S801, the system control unit 50 substitutes (Xave, Yave) [μm] calculated in S713 or S717 of FIG. 7 for the variable di. The variable di is the amount of movement having a directional component of the slide operation for the current acquisition (the most recent 50 msec if no touch-up has been performed).

In S802, the system control unit 50 determines whether or not the current operating mode is the OVF mode. If it is the OVF mode, proceed to S803; otherwise, proceed to S820.

In S803, the system control unit 50 adds the movement amount di substituted in S801 to the movement amount integrated value Dsum (two-dimensional coordinate value having a direction component).

In S804, the system control unit 50 determines whether or not the ranging area selection mode is set to one-point AF. If 1-point AF is set, the process proceeds to S805; otherwise, the process proceeds to S811.

In S<b>805 , the system control unit 50 calculates the movement speed (operation speed) of the slide operation for this acquisition (the most recent 50 msec if no touch-up has been performed). Specifically, the moving speed is calculated as Vdi=|di|/50 [msec]. |di|=√(Xave ² +Yave ² ). It should be noted that |di| itself is the amount of movement for each fixed time (50 msec), and therefore is proportional to the movement speed. Therefore, without dividing by the time (50 msec), the comparison with the threshold value in S806, which will be described later, may be the processing of comparing |di| with a threshold value (threshold value for comparison with |di|).

In S<b>806 , the system control unit 50 determines whether or not the moving speed Vdi of the slide operation for the current acquisition exceeds the threshold TH_V. If the moving speed Vdi exceeds the threshold TH_V (faster than the predetermined speed), the process proceeds to S807; otherwise (if the moving speed Vdi is equal to or less than the threshold TH_V), the process proceeds to S808.

In S807, the system control unit 50 sets parameters relating to the determination ellipse described later in S809 as follows.
Thx = Thx1
Thy = Thy1
(Thy1<Thx1)

Thx1 and Thy1 are values recorded in advance in the nonvolatile memory 56 and satisfy the relationship Thx1>Thy1. The reason why this relationship is satisfied is that, as will be explained later, it is more difficult to move the finger in the vertical direction than in the horizontal direction. This is so that the movement of the AF frame can be started with a shorter amount of movement compared to . Thx and Thy are variables that differ depending on conditions, but in any case, Thx is a value that defines the width of the judgment ellipse centered on the origin, and Thy is a value that defines the height of the judgment ellipse centered on the origin. A value to define. In the present embodiment, since Thx>Thy is satisfied in any case, the horizontal width of the determination ellipse=major axis=2Thx, and the vertical width of the determination ellipse=minor axis=2Thy.

In S808, the system control unit 50 sets parameters relating to the determination ellipse described later in S809 as follows.
Thx = Thx2
Thy = Thy2
(Thy2<Thx2)
(Thx1<Thx2, Thy1<Thy2)

Thx2 and Thy2 are values recorded in advance in the nonvolatile memory 56 and satisfy the relationship Thy2<Thx2. The reason why this relationship is satisfied is that, as will be explained later, it is more difficult to move the finger in the vertical direction than in the horizontal direction. This is so that the movement of the AF frame can be started with a shorter amount of movement compared to .

In addition, the relationships Thx1<Thx2 and Thy1<Thy2 are satisfied. That is, the ellipse defined by (Thx2, Thx2) is larger than the ellipse defined by (Thx1, Thy1). As a result, the determination using the large ellipse defined by (Thx2, Thx2) takes longer to start moving the AF frame than the determination using the small ellipse defined by (Thx1, Thy1). Requires travel distance. In the present embodiment, since a large ellipse is used for determination when the finger movement speed is slow, a longer movement distance is required to start moving the AF frame than when the finger movement speed is high. to This prevents the AF frame from moving too frequently or moving the AF frame too far when the user is trying to move the AF frame carefully by slowly moving the finger. You can fine-tune the position of the frame. In other words, reliable one-by-one movement (every movement amount) is realized.

In S809, the system control unit 50 determines whether or not the integrated value Dsum of the movement amount (the integrated value Dsumx of Xave and the integrated value Dsumy of Yave) has reached the edge or outside of the ellipse for determining whether the AF frame can be moved. judge. The decision ellipse is an ellipse defined by Equation 1 below.
^Dsumx2 /Thx+ ^Dsumy2 /Thy=1 Equation 1

That is, in S809, the system control unit 50 determines whether or not Expression 2 below is satisfied.
^Dsumx2 /Thx+ ^Dsumy2 /Thy≧1 Equation 2

If it is determined that Expression 2 is satisfied, the process proceeds to S810. If Expression 2 is not satisfied, that is, if the integrated value Dsum of the movement amount is inside the ellipse for determining whether the AF frame can be moved, the AF frame is not moved (moved to the selected position), but moved. End the determination process.

In S810, the system control unit 50 performs selection position movement processing 1 (AF frame movement processing). The selected position moving process 1 will be described later with reference to FIG. 10(a).

According to the determination in S809, if the movement direction is horizontal, the threshold for whether or not to move the AF frame is Thx. If the amount of movement of the finger is Thx or less, the AF frame is not moved. When the moving direction is right up, the threshold for whether or not to move the AF frame is Thy. is moved, and the AF frame is not moved if the amount of movement of the finger is less than or equal to Thy.

In S811, the system control unit 50 determines whether or not the ranging area selection mode is set to zone AF. If zone AF is set, the process proceeds to step S812, otherwise (for example, if automatic selection AF is set), the movement determination process ends.

In S812, the system control unit 50 sets parameters relating to the determination ellipse described later in S809 as follows.
Thx = Thx3
Thy = Thy3
(Thy3<Thx3)
(Thx1<Thx2<Thx3, Thy1<Thy2<Thy3)

Thx3 and Thy3 are values recorded in advance in the nonvolatile memory 56 and satisfy the relationship Thy3<Thx3. The reason why this relationship is satisfied is that, as will be explained later, it is more difficult to move the finger in the vertical direction than in the horizontal direction. This is so that the movement of the AF frame can be started with a shorter amount of movement compared to .

Further, the relationships Thx1<Thx2<Thx3 and Thy1<Thy2<Thy3 are satisfied. That is, an ellipse defined by (Thx1, Thy1) and (Thx2, Thx2)
The ellipse defined by (Thx3, Thy3) is larger than the ellipse defined by . As a result, determination using the large ellipse defined by (Thx3, Thx3) is better than determination using the small ellipse defined by (Thx1, Thy1) and (Thx2, Thy2). It takes longer distance to start. In this embodiment, when the range-finding area selection mode is zone AF, determination is performed using a large ellipse defined by (Thx3, Thx3). requires. The number of selectable positions (selectable zones) for zone AF (9) is smaller than that for single-point AF (191). Also, even if the zone AF is moved from end to end, the maximum amount of movement is two units (for example, from the leftmost zone in FIG. 5(d) to the rightmost zone in FIG. 5(g)). when moving). Therefore, there is little demand to quickly move the selection position a lot in zone AF. On the other hand, if the movement of the selection position occurs too frequently with a short amount of finger movement, it becomes difficult for the user to select the desired selection position (zone). Therefore, in this embodiment, when the number of selectable positions is small as in zone AF, a longer movement distance is required before the movement of the selection position starts, thereby facilitating fine adjustment of the selection position. ing. In other words, reliable one-by-one movement (every movement amount) is realized.

Note that the movement amount (movement distance) per movement amount (one time) of the AF frame in zone AF differs depending on the selected AF frame and is not constant. For example, when the camera is moved once to the left from the state shown in FIG. 5(a), the distance corresponding to seven distance measuring points is moved in the viewfinder display section 41 as shown in FIG. 5(d). On the other hand, when it is moved once from the state of FIG. 5(a), it moves a distance corresponding to three distance measuring points in the viewfinder display section 41 as shown in FIG. 5(b). Therefore, the relationship between Thx2 and Thx3 is not proportional to the relationship between the unit movement amount D2 (one distance measuring point) when Thx2 is used and the unit movement amount D3 (indefinite in zone AF) when Thx3 is used. That is, Thx2:Thx3≠D2:D3. The same is true for Thy2:Thy3.

In S820, the system control unit 50 determines whether or not the current operating mode is the LV mode. If it is the LV mode, proceed to S821; otherwise, proceed to S824.

In S821, the system control unit 50 determines whether or not the AF method (AF frame selection mode) is set to face+tracking AF. If the face+tracking AF is set, the process proceeds to S823; otherwise (for example, if the live single-point AF shown in FIG. 6A is set), the process proceeds to S822.

In S822, the system control unit 50 performs selection position movement processing 2 (AF frame movement processing). The selected position moving process 2 will be described later with reference to FIG. 10(b).

In S823, the system control unit 50 determines whether or not the face detected from the LV is selected (for example, the state shown in FIG. 6B). If it is determined that the face is not selected, the process advances to S822. If it is determined in S823 that the face has been selected, the process advances to S805. However, in the processing of S805 to S810 in this case, the y component of di is ignored and only the x component (horizontal direction movement component) is used. In the movement (change) of face selection, the adjacent face may be at a short distance (such as in a group photo) or at a long distance (case shown in FIG. 6B). Therefore, if the algorithm selects a face at a distance proportional to the amount of movement of the slide operation, the operation amount of the slide operation for selecting the adjacent face will change according to the distance between the faces. , does not give a constant feeling of operation. Therefore, in this embodiment, in the face selection state, the processing of S805 to S810 is performed to move the selection position by one each time the integrated value Dsum of the operation amount exceeds the determination ellipse. As a result, the operation amount of the slide operation for selecting the next face becomes constant to some extent regardless of the distance between the faces, and the user's operational feeling can be improved. Even in this case, since the process of comparing with the judgment ellipse of different size is performed according to the moving speed of the slide operation, it is easy to perform fine adjustment by the slide operation of slow movement. However, the present invention is not limited to this, and in the face selection state, processing may be performed in which comparison is made with the determination ellipse of the same size regardless of the moving speed of the slide operation.

In S824, the system control unit 50 performs processing according to the slide operation of the AF-ON button 1 in other operation modes. For example, a selection cursor movement operation on a menu screen, etc., will be omitted in this embodiment.

9(a) to 9(c) show operation examples when one touch operation (operation from touchdown to touchup) is performed on the AF-ON button 1 or 2 in single-point AF. . Each touch position described in FIGS. 9(a) to 9(c) is a touch position on a virtual plane. It is a relative touch position based on the amount of finger movement detected by the AF-ON button 1 or 2 .

In FIG. 9A, a slide operation (moving speed>threshold value TH_V) from position P0 to position P2 is performed. By the time 50 msec has elapsed from the start of the operation, the touch position moves from the position P0 to the position P1 by the movement amount d1, and goes out of the determination ellipse e1 centered at the position P0. Therefore, when 50 msec have elapsed, the selected position movement process 1 is performed, and the AF frame moves by a movement amount of 1 in the direction determined by the angle θ1. Although the details will be described later, at this time, the integrated value Dsum of the movement amount di is reset to 0 by the selection position moving process 1, and the center position of the judgment ellipse is reset to the position P1 (the integrated value Dsum and the judgment ellipse coordinate system is reset).

Similarly, in FIG. 9A, the touch position moves from the position P1 to the position P2 by the movement amount d2 in a period of 50 msec from the time when 50 msec has passed to the time when 100 msec has passed, and the determination ellipse e1 centered on the position P1 get out of Therefore, even after 100 msec has elapsed, the AF frame moves by a movement amount of 1 in the direction determined by the angle θ2. Also at this time, the integrated value Dsum is reset to 0, and the center position of the determination ellipse is reset to the position P2 (the integrated value Dsum and the coordinate system of the determination ellipse are reset).

In FIG. 9B, a slide operation (moving speed>threshold value TH_V) from position P0 to position P4 is performed. The touch position moves from the position P0 to the position P1 by the movement amount d1 within 50 msec from the start of the operation. The movement amount d1 in FIG. 9B is equal to the movement amount d1 in FIG. 9A, but in FIG. The touch position P1 at the time of progress is inside the determination ellipse e1. Therefore, when 50 msec has elapsed, the selected position moving process 1 is not performed, and the AF frame does not move. In this way, since it is determined using the ellipse whether or not to move the AF frame, even if the movement amount di of the touch position is the same, the AF frame may or may not move depending on the movement direction of the touch position. do. In addition, even if the same slide distance is slid in one slide operation (that is, a slide operation over 100 msec or more) over a plurality of times during the acquisition period (50 msec) of the amount of movement of the touch position, AF The movement amount of the frame is different. For example, when a slide operation is performed to the right in parallel with the X-axis with an operation amount (total movement distance of the touch position in one touch operation) of a distance M, a first movement amount (for example, 3 ) to move the AF frame to the right. On the other hand, when the slide operation is performed in parallel with the Y-axis and with the same operation amount as the above-mentioned distance M, the position of the AF frame is shifted by a second movement amount (for example, 5) larger than the first movement amount. moves upward.

Then, in FIG. 9B, the touch position moves from position P1 to position P2 by a movement amount d2 in a period of 50 msec from the point at which 50 msec has elapsed to the point at which 100 msec has elapsed.
Go out of the judging ellipse e1 centered at 0. Therefore, the selected position moving process 1 is performed for the first time after 100 msec has elapsed, and the AF frame is moved by a moving amount of 1. FIG. The moving direction of the AF frame is determined by the angle θ1 between the line segment (broken line in the drawing) connecting the positions P0 and P2 indicating the integrated value Dsum of the moving amounts d1 and d2 and the Y axis. At this time, the integrated value Dsum is reset to 0, and the center position of the determination ellipse is reset to the position P2 (the integrated value Dsum and the coordinate system of the determination ellipse are reset).

Similarly, in FIG. 9B, the touch position moves from the position P2 to the position P3 by the movement amount d3 before 150 msec elapses, but does not go outside the determination ellipse e1 centered at the position P2. , the AF frame does not move after 150 msec. By the time 200 msec has passed, the touch position moves from the position P3 to the position P4 by the movement amount d4, and goes out of the determination ellipse e1 centered at the position P2. Move by amount 1. The moving direction of the AF frame is determined by the angle θ2 between the line segment (broken line in the figure) connecting the positions P2 and P4 indicating the integrated value Dsum of the moving amounts d3 and d4 and the Y axis. At this time, the integrated value Dsum is reset to 0, and the center position of the determination ellipse is reset to the position P4 (the integrated value Dsum and the coordinate system of the determination ellipse are reset).

In FIG. 9C, a slide operation from position P0 to position P5 is performed. The touch position moves from the position P0 to the position P1 with the moving amount d1 and the moving speed higher than the threshold TH_V by the time 50 msec has elapsed from the start of the operation. Similarly, the touch position moves from the position P1 to the position P2 at a moving amount d2 and a moving speed faster than the threshold TH_V in a 50 msec period from the time when 50 msec has passed to the time when 100 msec has passed. Therefore, when 50 msec has passed and when 100 msec has passed, as in FIGS. Determination is made using the ellipse e1, and each AF frame moves by a movement amount of 1.

After that, the touch position moves at a moving speed slower than the threshold TH_V, so whether or not to move the AF frame is determined using the determination ellipse e2 with Thx=Thx2 and Thy=Thy2. Specifically, the touch position moves from the position P2 to the position P3 by the movement amount d3 in the period from the time when 100 msec has passed to the time when 150 msec has passed, but does not go outside the judgment ellipse e2 centered at the position P2. Therefore, the AF frame does not move after 150 msec. Similarly, the touch position moves from position P3 to position P4 by a movement amount d4 in a period of 50 msec from the time when 150 msec has passed until the time when 200 msec has passed. , the AF frame does not move after 200 msec. Then, in a period of 50 msec from the time when 200 msec has passed until the time when 250 msec has passed, the touch position moves from the position P4 to the position P5 by the movement amount d5, and goes out of the judgment ellipse e2 centered at the position P2. Therefore, when 250 msec has elapsed, the selected position movement process 1 is performed, and the AF frame is moved by a movement amount of 1. FIG. The moving direction of the AF frame is determined by the angle θ3 between the line segment (broken line in the drawing) connecting the position P2 and the position P5 indicating the integrated value Dsum of the moving amounts d3 to d5 and the Y axis. At this time, the integrated value Dsum is reset to 0, and the center position of the judgment ellipse is reset to the position P5 (the integrated value Dsum and the coordinate system of the judgment ellipse are reset).

If the determination ellipse e1 is always used, the touch position (position P4) will appear outside the determination ellipse e1 centered at the position P2, so the AF frame will move after 200 msec. In this embodiment, when the moving speed is slow, such a movement is prevented by using the determination ellipse e2 that is larger than the determination ellipse e1. As a result, the movement responsiveness of the AF frame is intentionally lowered to facilitate fine adjustment of the AF frame.

By the way, in FIG. 9(c), the touch position is greatly outside the judgment ellipse e1 by the movement amount d2 (the distance from the position P1 to the position P2 is more than twice the distance from the position P1 to the edge of the judgment ellipse e1). be). However, the amount of movement of the AF frame at the timing of position P2 is 1. In this way, the amount of movement of the AF frame once by the selection position movement process 1 is the same regardless of how the finger moves during one acquisition period (50 msec) of the movement amount di (the finger beyond the judgment ellipse is fixed regardless of the amount of movement of That is, the amount of movement of the finger and the amount of movement of the AF frame are not in a proportional relationship. For this reason, one AF frame is moved each time a quick slide operation is performed within one acquisition period (50 msec) of the movement amount di (for example, three AF frames are movement) can be used. As a result, it becomes possible to quickly and reliably move the AF frames one by one. Even a user who prefers to slide his/her finger a number of times corresponding to the desired amount of movement of the AF frame can move the AF frame point by point.

On the other hand, it is also possible to continuously move the AF frame greatly by one slide operation over two or more acquisition periods (100 msec or more) of the movement amount di. If the slide operation is performed for a long time at a certain speed, the AF frame moves by one every 50 msec, and the AF frame can be moved greatly by one slide operation.

It should be noted that the speed-specific thresholds as shown in FIG. 9C may be set in a shape different from the ellipse. For example, the threshold may be set with a circle of a different size for each movement speed so that the same threshold is used regardless of the movement direction of the slide operation.

Note that even when a face is selected in face+tracking AF, similarly to 1-point AF, determination ellipse e1 and determination ellipse e2 are used to determine whether or not to move the AF frame. In the case of zone AF, whether or not to move the AF frame is determined using a determination ellipse of Thx=Thx3 and Thy=Thy3. In the case of zone AF, the determination ellipse is not switched according to the moving speed.

FIG. 10(a) shows a flowchart of the selected position moving process 1. As shown in FIG. This process is the details of the process of S810 in FIG. 8 described above. Also, this process is realized by loading the program recorded in the nonvolatile memory 56 into the system memory 52 and executing it by the system control unit 50 .

In S1001, the system control unit 50 calculates the angle θ formed by the vector direction of the integrated value Dsum of the movement amount (two-dimensional coordinate value having a direction component). In the case of FIG. 9A, when 50 msec has elapsed from the start of the operation, the amount of movement d1 is set to the integrated value Dsum, and the angle θ1 formed by the integrated value Dsum (the direction from the position P0 to the position P1, in the Y direction (vertical direction) ) is calculated, and the integrated value Dsum is reset to zero. Then, when 100 msec has elapsed, the movement amount d2 is taken as the integrated value Dsum, and the angle θ2 formed by the integrated value Dsum is calculated. In the case of FIG. 9(b), the selected position movement process 1 is not performed after 50 msec, and the sum (dashed line) of the movement amount d1 and the movement amount d2 is set as the integrated value Dsum after 100 msec. The formed angle θ1 is calculated, and the integrated value Dsum is reset to zero. Then, when 150 msec has passed, the selected position movement process 1 is not performed, and when 200 msec has passed, the sum (dashed line) of the movement amount d3 and the movement amount d4 is taken as the integrated value Dsum, and the angle θ2 formed by the integrated value Dsum is calculated. be. Similarly, in the case of FIG. 9C, the angles θ1, θ2, and θ3 are calculated after 50 msec, 100 msec, and 250 msec have passed.

In S1002, the system control unit 50 determines the movement direction of the AF frame (selected position) based on the angle θ calculated in S1001. In the present embodiment, the angle θ is converted into one of eight directions of up, down, left, right, upper left, lower left, upper right, and lower right, as follows. Note that the number and direction of moving direction candidates are not particularly limited.
-22.5° (337.5°) < θ ≤ 22.5° Moving direction: Up 22.5° < θ ≤ 67.5° Moving direction: Right upper 67.5° < θ ≤ 112.5° …moving direction: right 112.5°<θ≦157.5°…moving direction: lower right 157.5°<θ≦202.5°…moving direction: down 202.5°<θ≦247.5°… Direction of movement: Lower left 247.5°<θ≦292.5° Direction of movement: Left 292.5°<θ≦337.5° Direction of movement: Upper left

In S1003, the system control unit 50 sets a fixed value of 1 as the movement amount of the AF frame. Note that the amount of movement of the AF frame may not be 1, and the user may designate (set) another amount of movement in advance.

In S1004, the system control unit 50 moves in the direction of movement determined in S1002 (one of the eight directions of up, down, left, right, upper left, lower left, upper right, and lower right) with the amount of movement 1 set in S1003. Move the AF frame. For example, when the AF frame is moved to the upper right by a movement amount of 1 from the state shown in FIG. 4A, the state shown in FIG. 4B is obtained. Note that when the AF frame is located at the end of the row or column of the range-finding point group, the AF frame does not move beyond the end (strikes at the end).

In S1005, the system control unit 50 resets the integrated value Dsum of the movement amount to zero.

FIG. 10(b) shows a flowchart of the selected position moving process 2. As shown in FIG. This process is the details of the process of S822 in FIG. 8 described above. Also, this process is realized by loading the program recorded in the nonvolatile memory 56 into the system memory 52 and executing it by the system control unit 50 .

In S1011, the system control unit 50 calculates the movement amount di, that is, the movement amount (X=Xave, Y=Yave) [μm], considering the aspect ratio and size of the live view image (LV image). Convert to the relative movement amount (X', Y') of the coordinate system of the image.

In S1012, the system control unit 50 multiplies the movement amount (X', Y') of the AF frame by a coefficient value to determine the movement amount of the AF frame. Specifically, the final value X' is determined by multiplying the value X' obtained in S1011 by a coefficient Kx, and the final value X' is determined by multiplying the value Y' obtained in S1011 by a coefficient Ky. Determine the value Y'. Note that if the coefficient value is 1, the process of S1012 may not be performed, and the coefficient values Kx and Ky may be any real values.

In S1013, the system control unit 50 relatively moves the AF frame by the movement amount (X', Y') determined in S1012. A slide operation to the upper right moves the AF frame (moves the selected position) as described with reference to FIG. 6A, for example.

In selection position movement processing 2, even if the movement distance of the slide operation does not exceed the elliptical threshold value described in S809 of FIG. 8, the AF frame is moved (moved the selection position) in proportion to the movement distance of the slide operation. . For example, in the LV mode, if the selection mode (designation mode) of the AF frame is live one-point AF (arbitrary selection) regardless of whether or not a face is detected, the selection position moves according to the slide operation. Processing 2 is performed. Therefore, in Live 1-point AF (arbitrary selection), when a slide operation is performed to the right parallel to the X axis, the integrated value of the movement distance of the slide operation is the ellipse determination threshold (because it is to the right parallel to the X axis, , even if the distance Thx1) is not exceeded, A
Movement of the F frame (movement of the selected position) is performed. On the other hand, in the LV mode, when the selection mode (designation mode) of the AF frame is the face+tracking priority AF that selects the face detected from the LV image, if the face is detected and selected, S823 is executed. It becomes Yes and progresses to S805. Then, after performing the processes of S805 to S808, when it is determined in S809 that the determination threshold for the ellipse is exceeded, selection position movement process 1 is performed according to the slide operation. Therefore, in face + tracking priority AF, when a slide operation is performed to the right parallel to the X axis, the integrated value of the moving distance exceeds the ellipse determination threshold (thx1 or Thx2 because it is right parallel to the X axis). The AF frame is not moved as long as it is not present, and is moved when the determination threshold of the ellipse is exceeded. That is, the subject (face) to be selected is changed. Note that the same processing as the above-described face+tracking priority AF may be performed in the AF frame selection mode that allows selection of other types of detectable subjects (eg pupils) in the LV mode. That is, if it is determined in S809 that the determination threshold for the ellipse has been exceeded, the selected position movement processing 1 may be performed according to the slide operation.

Using FIGS. 11(a) to 11(e), problems in the slide operation of the AF-ON button and the use of an ellipse for determination in the present embodiment (the amount of movement in the vertical direction is smaller than that in the horizontal direction). An example of the effect of starting the movement of the AF frame with ) will be described.

FIG. 11A shows how the user operates the AF-ON button 1 while holding the first grip section 101 with the right hand 1100 and holding the camera 100 horizontally. FIG. 11(b) shows the user holding the second grip section 102 with the right hand 1100, holding the camera 100 in the vertical position, and operating the AF-ON button 2. FIG. FIG. 11(c) shows how the user holds the first grip section 101 with the right hand 1100, holds the camera 100 vertically, and operates the AF-ON button 1. FIG. In any of FIGS. 11(a) to 11(c), the user operates the AF-ON button with the thumb 1101 of the right hand 1100. FIG.

FIG. 11(d) shows how the AF-ON button is laterally slid (slide in the lateral direction, specifically to the right). State 1141 is the start state of the lateral slide operation, state 1142 is the state during the lateral slide operation, and state 1143 is the end state of the lateral slide operation. As in states 1141 to 1143, the lateral slide operation is an operation that draws an arc with the base of the finger joint as a fulcrum. The lateral slide operation is relatively easy to perform (for example, it is easy to maintain the contact pressure on the AF-ON button and the contact portion), and a large amount of movement of the thumb 1101 is easily detected in the lateral slide operation. In particular, in the case of devices such as OTP that determine finger movement based on differences in finger image patterns, the characteristics of human fingerprints can be captured during horizontal slide operations, which makes it easy to maintain the contact pressure and contact area on the AF-ON button. It is stable and easy to detect, and it is easy to detect horizontal slide operation.

FIG. 11E shows how the AF-ON button is vertically slid (a vertical slide operation, specifically, an upward slide operation). In FIG. 11(e), the upper diagram is a schematic diagram when the AF-ON button is viewed from the rear side (the front side with respect to the operation surface of the AF-ON button), and the lower diagram is a side view. FIG. 4 is a schematic diagram of the AF-ON button viewed from the side; State 1151 is the start state of the vertical slide operation, state 1152 is the state during the vertical slide operation, and state 1153 is the end state of the vertical slide operation. As in states 1151 to 1153, the vertical slide operation is an operation that bends and stretches the finger joints. A vertical slide operation is relatively difficult to perform (for example, it is difficult to maintain the contact pressure on the AF-ON button or the contact portion), and it is difficult to detect a large amount of movement of the thumb 1101 in the vertical slide operation. In particular, in the case of devices such as OTP that determine finger movement based on differences in finger image patterns, the characteristics of human fingerprints can be detected during vertical slide operations where it is difficult to maintain the contact pressure and contact area on the AF-ON button. Stably difficult to detect, difficult to detect vertical slide operation. In FIG. 11E, the portion of the thumb 1101 near the fingertip contacts the AF-ON button and the vertical slide operation starts (side view of state 1151). Then, the contact portion of the AF-ON button changes so as to move away from the tip of the thumb 1101, and the vertical slide operation ends (side views of states 1152 and 1153).

Therefore, if the amount of movement (finger movement amount; threshold value) for starting the movement of the AF frame is the same for the horizontal slide operation and the vertical slide operation, it is difficult for the user to move the AF frame by the vertical slide operation. It makes me feel that it is difficult to do.

Therefore, in the present embodiment, as described in S809, an ellipse that is elongated in the horizontal direction is used as a threshold, and the movement of the AF frame is started with a smaller movement amount in the vertical direction than in the horizontal direction, and the AF frame is moved by the same amount. The amount of movement of the finger in the vertical direction is smaller than that in the horizontal direction. For example, in FIGS. 9A and 9B, the AF frame is moved by the same movement amount of 2, but FIG. distance) moves the AF frame by two. As a result, the user can perform slide operations in various directions with the same operational feeling. Note that the movement of the AF frame may be started with a smaller amount of movement in the vertical direction than in the horizontal direction, and the determination is not limited to the determination using an ellipse as in the present embodiment.
