Abstract
Foreign substance information including information on a position and size of a foreign substance in an imaging unit is acquired. When correcting a shadow of the foreign substance of the moving image data using the acquired foreign substance information and playing back the corrected moving image data, a selection is made whether to perform processing for correcting the shadow of the foreign substance of a frame based on the data size of the frame of the moving image data to be played back.
Claims7
An image processing apparatus for playing back moving image data, which is output from an imaging unit including an imaging sensor configured to capture a target image and an optical member arranged in front of the imaging sensor, that includes a shadow of a foreign substance adhered to a surface of the optical member, the image processing apparatus comprising:
- an acquisition unit configured to acquire foreign substance information that includes information on a position and a size of the foreign substance in the imaging unit;
- a playback unit capable of correcting the shadow of the foreign substance of the moving image data using the foreign substance information acquired by the acquisition unit and playing back corrected moving image data;
- and
- a selection unit configured to select whether to perform processing for correcting the shadow of the foreign substance of a frame based on a data size of the frame of the moving image data to be played back by the playback unit.
A method for controlling an image processing apparatus for playing back moving image data, which is output from an imaging unit comprising an imaging sensor configured to capture a target image and an optical member arranged in front of the imaging sensor, that includes a shadow of a foreign substance adhered to a surface of the optical member, the method comprising:
- acquiring foreign substance information that includes information on a position and a size of the foreign substance in the imaging unit;
- correcting the shadow of the foreign substance of the moving image data using the acquired foreign substance information and playing back corrected moving image data;
- and
- selecting whether to perform processing for correcting the shadow of the foreign substance of a frame based on a measure of the magnitude of movement between the frames of the moving image data to be played back.
A computer-readable storage medium storing program data for executing a method for controlling an image processing apparatus for playing back moving image data, which is output from an imaging unit comprising an imaging sensor configured to capture a target image and an optical member arranged in front of the imaging sensor, that includes a shadow of a foreign substance adhered to a surface of the optical member, the method comprising:
- acquiring foreign substance information that includes information on a position and a size of the foreign substance in the imaging unit;
- correcting the shadow of the foreign substance of the moving image data using the acquired foreign substance and playing back corrected moving image data;
- and
- selecting whether to perform processing for correcting the shadow of the foreign substance of a frame based on a measure of the magnitude of movement between the frames of the moving image data to be played back.
