[Example 1]
Next, the processing operation of the imaging apparatus 100 according to the first embodiment will be described with reference to the flowchart of FIG.

  In step S100, when the operator presses the operation unit 136, live view shooting is started. In step S101, the infrared light receiving and emitting unit 152 detects whether or not the operator's finger is close to the touch panel. If proximity is detected, the process proceeds to step S102. If no proximity is detected, the process returns to step S101. In step S102, the live view display is stopped.

  In step S103, similarly to step S101, the infrared light receiving and emitting unit 152 determines whether the operator's finger is close to the touch panel. If proximity is detected, the process proceeds to step S105. If no proximity is detected, the process proceeds to step S104. In step S104, the stop of the live view display is canceled, and the process returns to step S101. In step 105, the touch panel unit 151 determines whether a touch on the touch panel has been detected. If a touch is detected, the process proceeds to step S106. If no touch is detected, the process returns to step S103.

  In step S106, the object designated by the touch in step S105 is selected. Here, the object refers to image data of a certain fixed area centered on the coordinate position on the display image data corresponding to the touch detection coordinate position. FIG. 4 shows the state of the display image in step S106. Reference numeral 500 denotes an operator's finger, reference numeral 501 denotes a stopped display image, and reference numeral 502 denotes a subject. The fixed area is indicated by reference numeral 503 and is superimposed and displayed as an AF frame on the display image. The designated object is stored in the memory unit 127.

  In step S107, the stop of the live view display is canceled as in step S104. In step S108, the object selected in step S106 is searched for from the current live view captured image. A correlation value between the object data stored in step S106 and the current captured image data is calculated by the image processing unit 123 and the system control unit 120, and an area where a correlation value equal to or greater than a predetermined threshold is obtained is searched. In step S109, the timer unit 139 determines whether a predetermined time has elapsed. If the predetermined time has elapsed, the process proceeds to step S110. If the predetermined time has not elapsed, the process proceeds to step S111.

  In step S110, it is determined that the object has not been found, and the search is terminated, and an icon or a comment indicating that the search has failed is displayed on the display device 110. In step S111, it is determined whether or not an area where a correlation value equal to or greater than a predetermined threshold value has been searched. If there is an area equal to or greater than the threshold, it is determined that an object has been found, and the process proceeds to step S112. If there is no area equal to or greater than the threshold, the process proceeds to step S109.

  In step S112, the in-focus state of the object found in step S111 is measured by the distance measuring unit 143 or the image processing unit 123, and AF is performed. When the in-focus state is achieved, the operator notifies the operator of the success of AF by changing the color of the AF frame superimposed on the display image or by generating sound.

  In the first embodiment, the infrared light receiving and emitting unit 152 detects the proximity of the operator's finger. From live view display stop to touch can be performed continuously with the same finger, smooth operation becomes possible. Here, as a proximity means, a means different from the infrared light receiving and emitting unit 152 may be used as a matter of course. For example, it can be realized by using a capacitive touch panel. In a capacitive touch panel, the presence or absence of a touch is determined by detecting a change in capacitance. By providing two threshold values of the electrostatic capacitance, it is possible to distinguish and detect proximity and touch. If a capacitive touch panel is used, proximity detection can be realized without using a dedicated detection device.

[Example 2]
Next, the processing operation of the imaging apparatus 100 according to the second embodiment will be described with reference to the flowchart of FIG.

  In step S200, live view shooting is started when the operator presses the operation unit 136, as in step S100. In step S201, the touch panel unit 151 and the timer unit 139 determine whether or not there has been a predetermined n consecutive touches within a predetermined time. If a touch is detected n times continuously, the process proceeds to step S202. If no proximity is detected, the process returns to step S201.

  In step S202, the live view display is stopped as in step S102. In step S203, as in step S201, it is determined whether or not there has been a predetermined n consecutive touches within a predetermined time. If a touch is detected n times continuously, the process proceeds to step S205. If no proximity is detected, the process proceeds to step S204. Steps S204 to S212 are the same as steps S104 to S112, and a description thereof will be omitted.

  Unlike the first embodiment, the second embodiment does not require the infrared light receiving / emitting section 152. In addition, the touch panel is not limited to the capacitive type, and can be applied to any type of touch panel. In the second embodiment, it is configured to determine whether or not there has been a predetermined n consecutive touches within a certain time. However, for example, when a specific figure on the touch panel is traced with a finger, the live view display is stopped. It does not matter.

[Example 3]
Next, the processing operation of the imaging apparatus 100 according to the third embodiment will be described with reference to the flowchart of FIG.

  In step S300, live view shooting is started when the operator presses the operation unit 136, as in step S100. In step S301, it is determined whether or not a switch for stopping live view display has been pressed. The switches for stopping the live view display use the operation means 132, 133, 136, and the like. Alternatively, a new switch may be provided at a position indicated by 400 in FIG. If the position is 400, it can be operated with the left hand.

  In the imaging device of the lens unit exchange type as in the present embodiment, shooting is performed while holding the lens. Therefore, the position 400 is suitable for pressing a switch during shooting. If a switch for stopping the live view display is detected, the process proceeds to step S302. If not detected, the process returns to step S301.

  In step S302, the live view display is stopped as in step S102. In step S303, as in step S301, it is determined whether a switch for stopping live view display has been pressed. If a switch for stopping the live view display is detected, the process proceeds to step S305. If not detected, the process returns to step S304. Steps S304 to S312 are the same as steps S104 to S112, and a description thereof will be omitted.

  In the first embodiment, when the operator wants the subject to be AF using the touch panel, the live view display is always stopped. When shooting a stationary object, there is a possibility that the operator may feel troublesome. In the third embodiment, operation means other than the touch panel is used as means for stopping the live view display. For this reason, there is an advantage that the live view display is stopped only when the operator intends.

  The first to third embodiments of the present invention have been described above. According to the present embodiment, once the live view display is stopped, the operator can easily select a subject to be AFed. The present embodiment is particularly effective for a moving subject.

  In the first to third embodiments, the selected object is searched from the current live view captured image and AF is performed. However, the object may be tracked and AF may be performed as a matter of course. For example, every time the Live View captured image data is updated, an image area having the highest correlation with the stored image data of the object is detected, and the area with the highest correlation is updated as a new object. The image processing unit 123 repeats this process, so that the subject at the position designated by the operator can be tracked. Furthermore, by performing AF every time the image data is updated, the object can be tracked and AF can be performed. With this configuration, it is possible to perform AF more effectively on a moving subject.

  In the forms of the first to third embodiments, since the live view captured image cannot be confirmed while the live view display is stopped, there is a risk that the subject disappears from the captured image frame. In order to avoid this problem, the stopped live view image may be made translucent, monochrome display, or edge display and superimposed on the current live view captured image. This configuration is shown in FIG. Reference numeral 601 denotes a current live view photographed image, reference numeral 602 denotes a semi-transparent live view image, and reference numeral 603 denotes an AF frame. With this configuration, it is possible to reduce the risk of losing the subject from the captured image frame.

  Of course, there is no problem even if the current live view image is made translucent and superimposed on the stopped live view display image. The present invention is not limited to these embodiments, and various modifications and changes can be made within the scope of the gist. Note that the various controls described as being performed by the camera control unit 140 may be performed by a single piece of hardware, or the entire apparatus may be controlled by a plurality of pieces of hardware sharing the processing.

  Although the present invention has been described in detail based on the preferred embodiments thereof, the present invention is not limited to these specific embodiments, and various forms without departing from the gist of the present invention are also included in the present invention. included. Furthermore, each embodiment mentioned above shows only one embodiment of this invention, and it is also possible to combine each embodiment suitably.

  In the above-described embodiment, the case where the present invention is applied to the lens unit exchangeable imaging apparatus 100 has been described as an example. However, this is not limited to this example, and the live view captured by the imaging apparatus is Any imaging control device that can display the above is applicable.
