[0034] figure 1 (a) is a block diagram showing the main electrical configuration of the digital camera according to the first embodiment of the present invention. exist figure 1 In (a), the lens 1 is an optical lens for forming a subject image, and includes a focus lens, a zoom lens, and the like.
[0035] An imaging unit 3 including an imaging element 3A is disposed on the optical axis of the lens 1 and in the vicinity of forming a subject image. The imaging unit 3 photoelectrically converts a subject image by an imaging element, outputs image data in the form of a digital signal to the bus 11 , and inputs control signals and the like from the CPU 21 . In this embodiment, image data is output at 60 frames per second. Of course, it can also be more than 60 frames or less than 60 frames.
[0036] figure 1(b) shows a plurality of regions formed by dividing the imaging surface of the imaging element 3A. In the present embodiment, the imaging surface of the imaging element 3...

[0068] Next, use Figure 5 as well as Figure 6 A second embodiment of the present invention will be described. In the first embodiment, it is determined whether or not there is a stationary subject in the touch area for a first predetermined period of time, and if the subject moves, the subject is tracked. On the other hand, in the second embodiment, it is also determined whether or not there is a subject that was stationary before a second predetermined time (first predetermined time
[0069] The structure in this embodiment is different from that of the first embodiment figure 1 The shown block diagrams are the same, and detailed explanations are omitted. First, use Figure 6 The operation of this embodiment will be described. Should Figure 6 The illustrated example shows a tracking method in a case where there is a subject that has moved since the second predete...

[0083] Next, use Figure 7 to Figure 10 A third embodiment of the present invention will be described. In the first and second embodiments, a subject that was present in the touch area before the first predetermined time corresponding to the delay time of the user's touch is tracked and controlled to be focused on. On the other hand, in the third embodiment, the subject that has been present in the touched area for the longest time is tracked and controlled to be focused on.
[0084] The structure in this embodiment is the same as that of the first embodiment figure 1 The illustrated block diagrams have the same configuration, and therefore detailed descriptions are omitted. First, use Figure 9 as well as Figure 10 The operation of this embodiment will be described.
[0085] exist Figure 9 In the illustrated example, time T0 indicates the time when the user touches touch panel section 17 . Time T25 is earlier than time T0 by a time corresponding to the first predeter...
