Abstract
Official abstract text for this publication.
An imaging apparatus includes an imaging unit, a signal processing unit, and a pixel interpolation processing unit. The apparatus calculates a correlation degree for pairs in two orthogonal directions for an image signal obtained by the imaging unit including a single-chip image sensor having a four-color filter, such as a WRGB color filter, using pixel data in an area around a target pixel, using the correlation degree as a determination criterion in the interpolation. When a color component pixel with an identical color of a color component pixel subjected to pixel interpolation is not located in the direction having the high correlation, the pixel interpolation apparatus changes ratio in a direction orthogonal to the direction having the high correlation by using a pixel value resulting from color space conversion in the direction orthogonal to the direction having the high correlation, and performs pixel interpolation based on the change ratio.
First claim
Opening claim text (preview).
What is claimed is: 1. A pixel interpolation apparatus that performs pixel interpolation processing on an image obtained by an imaging unit, the imaging unit having color filters of four different colors arranged in a predetermined pattern, the apparatus comprising: a color saturation evaluation value obtaining unit configured to evaluate a color saturation of a predetermined image area of the image and obtain a color saturation evaluation value of the image area; a correlation…
