Abstract

An image processing device and an image processing method are disclosed. An image processor comprising: a first obtainer for obtaining a matching tap having a target pixel at its center; a second obtainer for obtaining a plurality of matching taps, each of the plurality of matching taps having a target pixel at its center one of the pixels in the search area of ​​pixels surrounding the pixel; a similarity recognizer that identifies a similarity-maximizing pixel among the matching taps obtained by the second recognizer, the similarity-maximized pixel representing the same a center pixel of a matching tap having the highest similarity to the acquired matching tap; and a mixing controller that combines a pixel value obtained by performing predetermined arithmetic processing on a pixel value of a prediction tap having a target pixel at its center with a pixel value at its center Pixel values ​​obtained by performing predetermined arithmetic processing on the pixel values ​​of the prediction taps having the similarity-maximized pixel at the center are mixed to calculate the pixel value of the target pixel.

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] In general, "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 informati...
