Patent ID: 8502896

Claim:
An imaging device, comprising: a lens optical system, for focusing light from a subject; color imaging means equipped with a Bayer pattern color filter, for imaging an image of the subject focused by the lens optical system; and an image processing section, for performing a filtering process in which data output by the color imaging means is passed through an image reconstructing filter having properties inverse blur properties of the lens optical system, then performing a synchronization process; wherein the image processing section collecting data excludes zero elements for each of R, G, and B channels, to generate reduced data arrays in which the amount of data is ¼ for the R and B channels, and the amount of data is ½ for the G channel, and administering the filtering process using the image reconstruction filter onto data of the reduced data array for each of the R, G, and B channels; wherein the image processing section is configured to: collect data excluding zero elements, and rotates the data array 45 degrees to generate the reduced data array for the G channel; administer the filtering process employing an image reconstruction filter, of which data have similarly been rotated 45 degrees, onto data that constitutes the reduced data array for the G channel; and rotate the data obtained by the filtering process 45 degrees, to return the orientation of the data array.
