Abstract
Official abstract text for this publication.
There is provided a signal processing device including a correction processing unit that acquires a pixel signal output from a sensor on which pixels are disposed in an array in which a spatial frequency of a color pixel which is a pixel acquiring a color component is lower than a spatial frequency of luminance pixels which are pixels acquiring luminance components, and then corrects the pixel signal output from a defective pixel out of the pixels that the sensor includes. During correction of a pixel signal of the color pixel, the correction processing unit performs correction referring to pixel signals of the luminance pixels having a spatial frequency higher than the spatial frequency of the color pixel.
First claim
Opening claim text (preview).
What is claimed is: 1. A signal processing device comprising a correction processing unit configured to (i) acquire pixel signals from a sensor on which pixels are disposed in an array in which a spatial frequency of color pixels of a first color which are pixels acquiring color components via first filters is lower than a spatial frequency of luminance pixels which are pixels acquiring luminance components via second filters, and (ii) correct a pixel signal from a defective pixel…
