Abstract
A smartphone includes a camera, a control section, and a storage section. 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.
Claims11
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.
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.
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.
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.
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.
