Image correction method, image correction device, and program
Abstract:
An image correction device includes a scene belonging rate computation unit that computes, from the feature value of an input image, a plurality of scene belonging rates each of which prescribes a probability with which the input image belongs to each category scene; an unknown scene belonging rate specification unit that specifies an unknown scene belonging rate prescribing a probability with which the input image belongs to an unknown scene; a by-scene correction parameter memory unit that stores by-scene correction parameters; a correction parameter combination unit that computes a combined correction parameter that is the weighted average of the correction parameters using the plurality of scene belonging rates and the unknown scene belonging rate; and an image correction unit that performs image correction processing for the input image using the combined correction parameter.
