The control section determines favorability of a composition of a target frame which is an arbitrary frame among a plurality of frames constituting the moving image. Then, in accordance with a result of determining the favorability of the composition of the target frame, the control section stores, in the storage section, a still image which corresponds to the target frame. ## Claims ### Claim 1 An image pickup device comprising: an image pickup section capable of capturing a still image and a moving image; a control device configured to control the image pickup section; and a storage section, the control device (i) determining favorability of a composition of a target frame which is an arbitrary frame among a plurality of frames constituting the moving image, and in accordance with a result of determining the favorability of the composition of the target frame, storing the still image in the storage section, the still image corresponding to the target frame. ### Claim 2 (depends on 1) The image pickup device as set forth in claim 1, further comprising: a display section, the control device storing, inn the storage section, the still image corresponding to the target frame inn either (i) a period during which a process for storing the moving image in the storage section is being carried out or a period during which a through-lens image corresponding to the moving image is being displayed on the display section. ### Claim 3 The image pickup device as set forth in claim wherein: the control device determines the favorability of the composition of the target frame, on the basis of at least one of the following Criteria 1 to 3: (Criterion 1) at least either hue or brightness in the target frame; (Criterion 2) a degree of blurring in the target frame; and (Criterion 3) a positional relation of respective images of two or more objects contained in the target frame. ### Claim 4 (depends on 1) The image pickup device as set forth in claim 1, wherein: the control device (i) calculates a composition score which is an index indicative of the favorability of the composition of the target frame, and stores, in the storage section, the still image corresponding to the tar frame, by using the composition score as the result of determining the favorability of the composition of the target frame. ### Claim 5 (depends on 1) The image pickup device as set forth in claim 1, wherein: a predetermined one of a plurality of objects, which are presented in the moving image, is regarded as a main object; and the control device (i) detects an image of the main object contained in the target frame; and stores the still image in the storage section, additionally in accordance with a result of detecting the image of the main object in the target frame, the still image corresponding to the target frame. ### Claim 6 The image pickup device as set forth in claim wherein: in a case where the image of the main object is detected in the target frame, the control device further detects a position and a size of the image of the main object in the target frame; and at least either (i) in a case where the image of the main object is not in a predetermined area in the target frame or (ii) in a case where the size of the image of the main object is smaller than a predetermined size in the target frame, the control device does not store, in the storage section, the still image corresponding to the target frame. ### Claim 7 (depends on 5) The image pickup device as set forth in claim 5, wherein: in a case where no image of the main object is detected in the target frame, the control device stores, in the storage section, the still image corresponding to the target frame in a case where the result of determining the favorability of the composition of the target frame is not less than a predetermined level. ### Claim 8 (depends on 5) The image pickup device as set forth in claim 5 wherein: in a case where the image of the main object is detected in the target frame, the control device further determines whether the image of the main object is blurring in the target frame; and in a case where the control device determines that the image of the main object is blurring in the target frame, the control device does not store, in the storage section, the still image corresponding to the target frame. ### Claim 9 The image pickup device as set forth in claim wherein: in a case where the control device detects images of a plurality of main object candidates in the target frame on an assumption that the main object candidates are objects which are same in kind as the main object, the control device selects, as the main object in the target frame, one main object candidate from among the plurality of main object candidates, the one main object candidate being selected on the basis of at least one of a position and a size of each of the images of the plurality of main object candidates in the target frame. ### Claim 10 (depends on 1) The image pickup device as set forth in claim 1, further comprising: a display section, the control device causing the display section to display an image indicating that the image pickup device is operating in a special mode in which the still image corresponding to the target frame is selectively stored in the storage section, the special mode being an image capture mode of the image pickup device. ### Claim 11 A method for controlling an image pickup device, the image pickup device including an image pickup section capable of capturing a still image and a moving image, and a storage section, the method comprising the steps of: (i) determining favorability of a composition of a target frame which is an arbitrary frame among a plurality of frames constituting the moving image; and (ii) in accordance with a result of determining the favorability of the composition of the target frame, storing the still image in the storage section, the still image corresponding to the target frame.
