Image capture apparatus and method
First Claim
1. An image capture apparatus comprising:
- an image capture unit having a plurality of exposure adjustment functions including an electronic shutter function for changing an exposure time within a frame period and configured to capture an image of a subject to obtain image data; and
an image-capture control unit configured to allow the image capture unit to execute an image capture operation of capturing a plurality of frames of image data having continuity in time at a fixed frame rate and configured to perform exposure adjustment control in accordance with a subject brightness level obtained during the execution of the image capture operation, the exposure adjustment control being performed using preferentially an exposure adjustment function other than the electronic shutter function.

15. An image capture apparatus comprising:
-
an image capture unit having an electronic shutter function for changing an exposure time and configured to capture an image of a subject to obtain image data; and an image-capture control unit configured to perform a control process for allowing the image capture unit to execute an image capture operation of capturing a plurality of frames of image data having continuity in time at a fixed frame rate so that divisional exposure is continuously executed within an exposure period at the fixed frame rate using the electronic shutter function, and to combine a plurality of pieces of captured image data obtained using the divisional exposure to produce image data of one frame.

16. An image capture method comprising the steps of:
-
executing an image capture operation of capturing a plurality of frames of image data having continuity in time at a fixed frame rate; and performing exposure adjustment control in accordance with a subject brightness level obtained during the execution of the image capture operation, the exposure adjustment control being performed using preferentially an exposure adjustment function other than an electronic shutter function.
