Abstract

Disclosed are an image processing apparatus, an image processing method, and a program. An image processor includes a first acquirer that acquires a matching tap having a target pixel at the center, a second acquirer that acquires plural matching taps each having, at the center, one of pixels in a search area including the pixels surrounding the target pixel, a similarity identifier that identifies, among the matching taps acquired by the second acquirer, a similarity maximizing pixel representing a central pixel of the matching tap having the highest similarity to the matching tap acquired by the first acquirer, and a mixing controller that computes a pixel value of the target pixel by mixing a pixel value obtained by performing a predetermined arithmetic process on pixel values of a prediction tap having the target pixel at the center with a pixel value obtained by performing a predetermined arithmetic process on pixel values of a prediction tap having the similarity maximizing pixel at the center.

Description

technical field [0001] The present disclosure relates to an image processing device, an image processing method, and a program, and in particular, to an image processing device, an image processing method, and a program capable of restoring detail sharpness of any region of an image. Background technique [0002] Often, "information" has a bias (universality) of energy (entropy). This bias was identified as informative (valuable information). [0003] For example, an image obtained by photographing a certain scenery is recognized by humans as an image of the scenery because the image (pixel values ​​of pixels constituting the image) has an energy bias corresponding to the scenery. An image without energy bias is just noise or the like, and is worthless as information. [0004] Therefore, even when the original energy bias of valuable information is "destroyed" by manipulating the information in a certain way, the original information can be restored from the information su...
