CCD data pixel interpolation circuit and digital still camera equipped with it

Year	Description
1998	Invention patented by Keisuke Miyamoto on September 28th, 1998. Abstract: A pixel interpolation circuit in the digital still camera according to the present invention, filters unnecessary pixel data from pixel data read out from a CCD which has captured an image, and stores only necessary pixel data for a pixel interpolation operation, in a dual-port data buffer. At the same time, the pixel interpolation circuit reads out necessary data for the pixel interpolation operation, from the data buffer, performs the pixel interpolation operation, and stores the result in a video memory. The pixel interpolation operation is performed by weighting pixels to be used for the pixel-interpolation operation, in accordance with the distance between a pixel to be interpolated and each of the to-be-weighted pixels.
