-A state in which nothing is touched on the AF-ON button 1 or the AF-ON button 2 (hereinafter, referred to as touch-off).

When touchdown is detected, touch-on is also detected at the same time. After a 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, if the movement amount (x, y) is 0, the touch move is not detected. After it is detected that all the touched fingers have touched up, the touch-off is performed.

The system control unit 50 determines what kind of operation (touch operation) is performed on the AF-ON buttons 1 and 2 based on these operations / states, the moving direction, and the moving amount (x, y). Regarding the touch move, the movement of the finger etc. on the AF-ON buttons 1 and 2 is in the eight directions of up, down, left, right, upper left, lower left, upper right, lower right, or in the x-axis direction and y-axis direction. Detects movement in the two-dimensional direction. The system control unit 50 determines that the slide operation has been performed when the movement in any of the eight directions or the movement in one or both of the two-dimensional directions in the x-axis direction and the y-axis direction is detected. It shall be. It is determined that the tap operation has been performed when the finger is touched on the AF-ON buttons 1 and 2 and the touch is released within a predetermined time without performing the slide operation. In the present embodiment, the AF-ON buttons 1 and 2 are infrared touch sensors. However, a touch sensor of another method such as a resistive film method, a surface acoustic wave method, a capacitance method, an electromagnetic induction method, an image recognition method, or an optical sensor method may be used.

[Display control according to movement operation]
Hereinafter, with reference to the flowcharts of FIGS. 3 and 4 and the time chart of FIG. 5, the display control method according to the movement operation (touch move) for moving the contact position while in contact with the operation surface of the AF-ON button 1. I will explain. In the present embodiment, when the speed of the movement operation is slow, the possibility that the processing unintended by the user is executed is reduced by increasing the time (delay time) until the movement operation is reflected on the display. Further, in the present embodiment, the AF frame is described as being moved by the movement operation (touch move) to the AF-ON button 1. However, depending on the touch move, for example, the position of the pointer (position index) may be moved. Arbitrary processing such as changing the exposure value may be performed.

FIG. 3 is a flowchart showing a process of determining a time (delay time) until the movement operation is reflected on the display. FIG. 4 is a flowchart showing a display control process according to the delay time. FIG. 5 is an example of a time chart relating to these processes. In the time chart of FIG. 5, the horizontal axis indicates that time (time) has elapsed from left to right. Further, FIG. 5 shows a display stop operation, which will be described later, a movement amount of the touch move, a speed of the touch move, a display timing according to the movement amount, and a time change of the display according to the movement amount.

In the following description, it is assumed that the period corresponding to the sampling number n is the target of the processing at the start of the processing of S301 and S401. Here, it is assumed that the sampling number n is independently held in the processing of the flowcharts of FIGS. 3 and 4. For example, even if the sampling number n is increased in the processing of the flowchart of FIG. 3, the sampling number n is not increased in the processing of the flowchart of FIG.

The processing of the flowcharts of FIGS. 3 and 4 is realized by expanding the program stored in the non-volatile memory 56 into the system memory 52 and executing the program by the system control unit 50. Further, the system control unit 50 shall execute the processes shown in the flowcharts of FIGS. 3 and 4 in parallel at the same time.

(Determining delay time)
First, using the flowchart of FIG. 3, the process of determining the delay time, which is the time from when the AF-ON button 1 accepts the user's movement operation (touch move) until the movement operation is reflected on the screen display. explain.

In S301, the system control unit 50 determines whether or not the image can be displayed on the display unit 28 or the display unit 41 in the finder. If it can be displayed, the transition to S302 is performed, and if not, the processing of S301 is performed again.

In S302, the system control unit 50 detects a movement operation (touch move) while the user touches the AF-ON button 1 and acquires a movement amount (x, y). In S302, the system control unit 50 acquires the movement amount (x, y) for each sampling cycle T0. That is, it can be said that the AF-ON button 1 accepts the movement operation every sampling cycle T0.

In S303, the system control unit 50 detects (determines) _{the speed V n} of the movement by the touch operation from the acquired movement amount (x, y). Here, the system control unit 50 a filtering process for a predetermined sampling period average value, a median value and a mode value and velocity V _n of the speed of movement in the (partial period of the sampling period T0), the speed V _n may be determined. The speed V _n indicates a speed corresponding to the period corresponding to the sampling number n. For example, the speed corresponding to the period corresponding to the sampling number n-1 will be described as the _{speed V n-1.}

In S304, the system control unit 50 determines whether the speed V _n detected is smaller than the speed threshold value Vth which is set in advance. If the velocity V _n is smaller than the velocity threshold value Vth, the transition to S305 is performed, and if not, the transition to S306 is performed. That is, if the received touch move is fast, the transition to S306 is performed, and if the touch move is slow, the transition to S305 is performed.

In S305, the system control unit 50 sets the time T1 as the delay time _{T n.} Here, the delay time T _n, in the present embodiment, as shown in FIG. 5, (after receiving a touch move) after obtaining the movement amount during the period corresponding to the sampling number n, the amount of movement Indicates the time elapsed until the corresponding display is displayed. In the present embodiment, when the touch move is AF-ON button 1 reception delay time T _n elapses after, AF frame at a position corresponding to the movement amount of the touch move moves. In the example shown in FIG. 5, when the amount of movement is acquired during the time period from t1~ time t2, time T1 as a delay time T _n with respect to the amount of movement is set. Incidentally, in S305, the system control unit 50, the delay time _{T n} (time T1), may be determined to be longer as the difference of the velocity _{V n} and the speed threshold value Vth is great.

In S306, the system control unit 50 sets the shorter T2 than the time T1 as a delay time _{T n.} The time T2 may be zero. In the example shown in FIG. 5, when the amount of movement is acquired for a period of time t0~ time t1 and time t2~ time t4, the time T2 as the delay time T _n with respect to the amount of movement is set.

Here, in S304 to S306, the system control unit 50, even if the percentage of time that the speed _{V n} in a predetermined sampling period falls below a speed threshold value Vth is set to time T1 as a delay time _{T n} when the predetermined ratio or more Good. At this time, the system control unit 50, the proportion of the period during which the velocity V _n is below a speed threshold value Vth may be set time T2 as the delay time T _n when it is less than a predetermined ratio. The system control unit 50, when the ratio of the period below the velocity V _n is the speed threshold value Vth in a predetermined sampling period is a predetermined ratio or more, more the below period is longer, determines a longer delay time T _n May be good. _{Further, in S304 to S306, the system control unit 50 determines the speed V n} from the speeds at a plurality of time points in a predetermined sampling period, and the smaller the number of the plurality of time points, the longer the delay time _Tn is determined. You may. This is because smaller the number of the plurality of time points, for the accuracy of the velocity V _n (reliability) is low, since the detected operation whether it is intended operation of the user is not clear, the delay time T _This is because it is preferable that n is sufficiently long. Here, the number at a plurality of time points may be changed by a user operation.

In S307, the system control unit 50 increments the sampling number n by 1. That is, in S307, the system control unit 50 changes the period to be processed in the flowchart of FIG. 3 to the next period. As described above, even if the system control unit 50 increments the sampling number n in S307, the sampling number n in the processing of the flowchart shown in FIG. 4 is not incremented.

In S308, the system control unit 50 determines whether or not an operation for ending the display of the display unit 28 or the display unit 41 in the finder has been performed. Here, for example, when the user presses a predetermined button, the system control unit 50 can determine that the operation for ending the display has been performed. When the operation is performed, all the processing of this flowchart ends. If not, the process proceeds to S309.

In S309, the system control unit 50 determines whether or not the sampling cycle T0 has elapsed since the start of the previous processing of S302. If the sampling cycle T0 has elapsed, the transition to S302 is performed, and if not, the processing of S309 is performed again.

(Display control processing according to delay time)
Next, using the flowchart of FIG. 4, a process (display control) for controlling the display timing according to the received user's move operation (touch move) based on the delay time set in S305 or S306 will be described. ..

In S401, the system control unit 50 determines whether the velocity _{V n} detected (determined) in S303. In other words, in S401, the system control unit 50 determines whether or not the AF-ON button 1 has accepted the touch move for the sampling number n. If the velocity V _n is detected, the transition to S402 is performed, and if not, the process of S401 is performed again.

In S402, the system control unit 50 determines whether or not an operation for ending the display of the display unit 28 or the display unit 41 in the finder has been performed, similarly to S308. If the operation is performed, the transition to S409 is performed, and if not, the transition to S403 is performed.

In S403, the system control unit 50 determines whether or not the movement stop operation has been performed. If the movement stop operation is performed, the transition to S408 is performed, and if not, the transition to S404 is performed. The movement stop operation includes, for example, an operation for executing a process such as AF or confirmation of the selection of the subject at the position where the pointer moved by the touch move is displayed. Further, in the present embodiment, it can be said that the movement stop operation is an operation in which the movement amount at the current sampling number n is discarded, that is, an operation in which the movement amount is not reflected in the display. More specifically, the system controller 50, before the delay time elapses T _n after receiving a touch move, when the travel stop operation has been performed, (processing S407) the display control corresponding to the sampling number n Do not execute. Even in the example of FIG. 5, the movement amount acquired immediately before the time t3 and the time t5 when the movement stop operation is performed is not reflected in the display.

Here, the movement stop operation may be a pressing operation (pressing operation) on the operation surface of the AF-ON button 1, or a touchdown (contact) or touchup (release of contact) operation on the operation surface. More specifically, if the movement stop operation is an operation that is performed on the operation surface of the AF-ON button 1 that is different from the touch move, and is a new (not a continuous operation) operation. Good. In FIG. 5, the pressing operation on the operation surface of the AF-ON button 1 is used as an example, the system control unit 50 newly detects the pressing operation at time t3, and newly releases the pressing operation at time t5. Indicates that it has been detected. Here, for example, when the AF-ON button 1 is pressed, the system control unit 50 executes AF at the current display position of the AF frame. It should be noted that the processing corresponding to the movement stop operation such as AF is executed without delay when the operation is performed.

In S404, the system control unit 50, from the detection of the velocity V _n (from accepting touch move) it determines whether the delay time T _n has elapsed. If the delay time _Tn has elapsed, the transition to S407 occurs, and if not, the transition to S405 occurs.

In S405, the system control unit 50 determines whether or not the sampling cycle T0 has elapsed after detecting _{the velocity V n (after receiving the touch move).} If the sampling cycle T0 has elapsed, the transition to S406 is performed, and if not, the transition to S402 is performed.

In S406, the system control unit 50 determines whether or not the _{delay time Tn} is larger than the sum of the delay time Tn _{+ 1 and the sampling period T0.} The transition to the S408 it is larger, the delay time _{T n,} a transition to S402 otherwise. That is, the system control unit 50 from accepting touch move until the elapse of the delay period T _n, if it is the subsequent display control corresponding to the touch move the accepted, the display control corresponding to the sampling number n Is not executed. This is because if the delay time T _n is larger, the movement amount corresponding to the sampling number n is reflected later than the movement amount corresponding to the sampling number n + 1, and the user's operability is poor. .. Therefore, as this phenomenon does not occur, the larger the better the delay time T _n, makes a transition to S408, is not carried out to reflect the movement amount corresponding to the sampling number n.

In S407, the system control unit 50 executes a display event for displaying on the display unit 28 or the display unit 41 in the finder according to the touch move (movement amount). In the present embodiment, the system control unit 50 moves the AF frame on the screen of the display unit 28 or the display unit 41 in the finder to a position according to the amount of movement.

In S408, the system control unit 50 increments the sampling number n by 1. That is, in S408, the system control unit 50 changes the period to be processed in the flowchart of FIG. 4 to the next period.

In S409, the system control unit 50 ends the display of the image on the display unit 28 or the display unit 41 in the finder.

As described above, when the speed of the touch move is slow, a delay time is provided from the reception of the touch move to the display according to the movement amount of the touch move (from the start time of the sampling cycle T0). That is, when the speed of the touch move is high, the display control is performed according to the touch move before a predetermined time after the touch move is detected, and when the speed of the touch move is slow, the touch move is detected. The display is controlled according to the touch move after a predetermined time. According to the delay in this way, for example, when a movement operation of a small amount of movement is accepted by pressing the AF-ON button 1, the system control unit 50 immediately before the movement operation. The process corresponding to the pressing can be performed at the position where the movement amount is ignored. That is, since the process corresponding to the pressing can be executed before the display is delayed, it is possible to suppress the influence of the movement operation not intended by the user on the processing corresponding to the pressing.

Further, before the delay time elapses T _n after receiving a touch move, when an operation other than touch move (move stop operation) is newly detected, displays a moving amount detected immediately before (last) Not reflected in. Further, when the movement amount corresponding to the sampling number n is reflected after the movement amount corresponding to the sampling number n + 1 is reflected, the movement amount corresponding to the sampling number n is not reflected. As a result, it is possible to further reduce the possibility that an operation not intended by the user is reflected in the display.

For example, this embodiment is applicable. For example, instead of the AF-ON button 1, the processing of the flowchart may be executed according to the operation on the touch panel 70a.
