Abstract:
A digital camera which creates zoom image data having a desired zoom magnification, comprising:an imager for imaging an object; a video memory for holding source image data corresponding to an object image obtained by said imager; a buffer having at least a first capacity corresponding to a data amount of particular source pixels required to create one zoom pixel; a transferor for transferring from said video memory to said buffer, pixel data containing the particular source pixels at a high speed clock rate; a reader for reading the pixel data held in said buffer at a reference clock rate slower than said high speed clock rate; and a creator for creating pixel data for the zoom pixel based on an output of said buffer, wherein the particular source pixels include a plurality of pixels in a vertical direction, said high speed clock rate is a rate multiplying said reference clock rate by the number of vertical pixels or more of the particular source pixels, said imager outputs the source image data in a luster scan manner, said transfer or transfers the pixel data in a special scan manner different from the luster scan manner, and said reader reads the pixel data in a manner by which the zoom image data is created in the luster scan manner.
