Abstract
Output signals (pixel values) output from a sensor unit in which image sensors having six kinds of color filters with different colors are arranged are classified in association with three stimulus values, a color number is reduced by performing addition processing of the output signals (pixel values) in each classification to generate an image signal of three bands, and the generated image signal is used for the preview display so that a photographed image can be checked easily and immediately.
Claims13
An imaging apparatus, comprising:
- an imaging unit in which image sensors having four kinds of color filters or more with different colors are arranged;
- a color number reduction processing unit which generates an image signal of three bands corresponding to three stimulus values, from output signals corresponding to the four kinds of color filters or more output from the imaging unit;
- and
- an auto-focus control unit which controls focusing of an object image in the imaging unit based on the image signal generated by the color number reduction processing unit.
