Abstract
Official abstract text for this publication.
Provided is an image processing apparatus including a periodicity determining unit that determines whether a determination area including a target defective pixel is a periodicity area, a first pixel value generating unit that generates a pixel value by a first supplementing method, a second pixel value generating unit that generates a pixel value by a pixel second supplementing method, a control unit that determines which of the first pixel value generating unit and the second pixel value generating unit is to be used based on the determination by the periodicity determining unit, a pixel value supplementing unit that inserts the pixel value generated by the pixel value generating unit determined to be adopted, and a pixel value updating unit that updates pixel values of neighboring pixels of the defective pixel.
First claim
Opening claim text (preview).
The invention claimed is: 1. An image processing apparatus comprising: a periodicity determining unit that sets a determination area including a defective pixel having a pixel value to be supplemented in a target image and determines whether the determination area is a periodicity area where pixel values of pixels included in the determination area periodically vary or a non-periodicity area where pixel values of pixels included in the determination area do not periodically vary;…
