Abstract
A method for reducing artefacts caused by the presence of flicker during image capture. The method comprises performing image capture to produce image capture data corresponding to an image capture scene, the image capture data including a first image having a first exposure and a second image having a second exposure. The image capture data is processed to: (a) detect a discrepancy in the second image with respect to the first image; and (b) determine flicker indication data indicative of a presence of flicker in the second image. The discrepancy is corrected in dependence upon the flicker indication to produce a flicker-reduced version of the second image.

A method for reducing artefacts caused by the presence of flicker during image capture, the method comprising:
- performing image capture to produce image capture data corresponding to an image capture scene, the image capture data including a first image having a first exposure and a second image having a second exposure;
- processing the image capture data to:
- (a) detect a discrepancy in the second image with respect to the first image;
- and
- (b) determine flicker indication data indicative of a presence of flicker in the second image, and
- in dependence upon said flicker indication data, correcting the discrepancy in said second image to produce a flicker-reduced version of the second image.
An apparatus for reducing artefacts caused by the presence of flicker during image capture, the apparatus comprising:
- a receiver configured to receive image capture data corresponding to an image capture scene, the image capture data including a first image having a first exposure and a second image having a second exposure;
- and
- a processor configured to process the image capture data to:
- (a) detect a discrepancy in the second image with respect to the first image;
- and
- (b) determine flicker indication data indicative of a presence of flicker in the second image,
- the processor being configured to, in dependence on said flicker indication data, correct the discrepancy in said second image to produce a flicker-reduced version of the second image.
A non-transitory computer-readable storage medium comprising a set of computer-readable instructions stored thereon which, when executed by at least one processor, cause the at least one processor to:
- receive image capture data corresponding to an image capture scene, the image capture data including a first image having a first exposure and a second image having a second exposure;
- process the image capture data to:
- (a) detect a discrepancy in the second image with respect to the first image;
- and
- (b) determine flicker indication data indicative of a presence of flicker in the second image, and
- in dependence upon said flicker indication data, correct the discrepancy in said second image to produce a flicker-reduced version of the second image.
