Abstract
The image pickup apparatus of the present invention sets at least an imaging magnification of an optical system included in a second image pickup device or a sampling pitch of a signal in the second image pickup device; calculates, using image data of a plurality of frames captured by second image pickup device during exposure of first image pickup device for image data of a first frame, the amount of subject motion in the image data of the plurality of frames; and controls the exposure of the first image pickup device for the image data of the first frame, on the basis of the calculated amount of subject motion.
Claims20
An image pickup apparatus comprising:
- first image pickup device;
- second image pickup device;
- and
- at least one processor or circuit configured to perform the operations of following units:
- calculating unit configured to calculate, using image data of a plurality of frames captured by the second image pickup device during exposure of the first image pickup device for image data of a first frame, the amount of subject motion in the image data of the plurality of frames;
- control unit configured to control the exposure of the first image pickup device for the image data of the first frame, on the basis of the amount of subject motion calculated by the calculating unit;
- and
- setting unit configured to set at least an imaging magnification of an optical system included in the second image pickup device or a sampling pitch of a signal in the second image pickup device, in accordance with a resolution of image data generated by the first image pickup device, a resolution of image data generated by the second image pickup device, and a permissible blur value in the first image pickup device.
An image pickup apparatus removable from an external image pickup apparatus including first image pickup device, the image pickup apparatus comprising:
- second image pickup device;
- and
- at least one processor or circuit configured to perform the operations of following units:
- calculating unit configured to calculate, using image data of a plurality of frames captured by the second image pickup device during exposure of the first image pickup device for image data of a first frame, the amount of subject motion in the image data of the plurality of frames;
- control unit configured to output a signal for controlling the exposure of the first image pickup device for the image data of the first frame, on the basis of the amount of subject motion calculated by the calculating unit;
- and
- setting unit configured to set at least an imaging magnification of an optical system included in the second image pickup device or a sampling pitch of a signal in the second image pickup device, in accordance with a resolution of image data generated by the first image pickup device, a resolution of image data generated by the second image pickup device, and a permissible blur value in the first image pickup device.
A control method of an image pickup apparatus, the method comprising:
- setting at least an imaging magnification of an optical system included in a second image pickup device or a sampling pitch of a signal in the second image pickup device, in accordance with a resolution of image data generated by first image pickup device, a resolution of image data generated by the second image pickup device, and a permissible blur value in the first image pickup device;
- calculating, using image data of a plurality of frames captured by the second image pickup device during exposure of the first image pickup device for image data of a first frame, the amount of subject motion in the image data of the plurality of frames;
- and
- outputting a signal for controlling the exposure of the first image pickup device for the image data of the first frame, on the basis of the amount of subject motion.
A non-transitory computer-readable storage medium storing a program executed by a computer included in an image pickup apparatus, the program causing the computer of the image pickup apparatus to execute the steps of:
- setting at least an imaging magnification of an optical system included in a second image pickup device or a sampling pitch of a signal in the second image pickup device, in accordance with a resolution of image data generated by a first image pickup device, a resolution of image data generated by the second image pickup device, and a permissible blur value in the first image pickup device;
- calculating, using image data of a plurality of frames captured by the second image pickup device during exposure of the first image pickup device for image data of a first frame, the amount of subject motion in the image data of the plurality of frames;
- and
- outputting a signal for controlling the exposure of the first image pickup device for the image data of the first frame, on the basis of the amount of subject motion.
