Apparatus and method for reducing distortion in images

A non-transitory computer-readable storage medium, comprising executable instructions which, when executed by a processor, cause the processor to perform operations comprising:

• determining a chrominance reference comprising a collection of respective measurements of chrominance of a plurality of objects in frames in video content each having a luminance less than a reference luminance;
• detecting a distorted frame in the video content, wherein the distorted frame is distorted at least in part by a burst of light;
• modifying a chrominance of an object in the distorted frame according to the chrominance reference without altering spatial characteristics of objects in the distorted frame to produce a modified frame;
• and
• presenting updated video content at a presentation device, wherein the updated video content has the modified frame.

A method, comprising:

• determining, by a set-top box comprising a processor, a chrominance reference comprising a collection of respective measurements of chrominance of a plurality of objects in image frames in visual content each having a luminance less than a reference luminance;
• detecting, by the set-top box, an image frame in the visual content affected at least in part by a burst of luminance, wherein the affected image frame has a luminance greater than a reference luminance;
• modifying, by the set-top box, chrominance of objects in the affected image frame according to the chrominance reference and without altering spatial characteristics of the objects in the affected image frame to produce a modified image frame;
• and
• presenting, by the set-top box, updated visual content at a presentation device having the modified image frame.
