Image processing apparatus and image processing method

摘要

An image processing apparatus includes a change unit configured to change a driving state of an image sensor for capturing an image signal in response to an operation for changing the driving state of the image sensor, and a flicker correction unit configured to correct an image signal based on a flicker component detected from image signals of a frame captured a predetermined number of frames before the frame of the image signal to be corrected, wherein the flicker correction unit is configured to change the predetermined number when the driving state of the image sensor is changed by the change unit.

1. An image processing apparatus comprising:
a change unit configured to change a driving state of an image sensor for capturing an image signal in response to an operation for changing the driving state of the image sensor; and a flicker correction unit configured to correct an image signal captured in a present driving state of the image sensor based on a flicker component detected from an image signal, which is captured in a previous driving state of the image sensor, of a frame captured a number of frames prior to the image signal, wherein when the driving state of the image sensor changes from a driving state of a moving image capturing to a driving state of a still image capturing, and further changes to the driving state of the moving image capturing, the flicker correction unit corrects an image signal of a captured still image based on a flicker component detected from a predetermined number of frames prior to the captured still image, and corrects an image signal of a newly captured moving image based on a flicker component detected from the previously captured frame of the image signal in the driving state of the moving image capturing not using the captured still image.
