Abstract:
1. An image recognition device for generating an output rotation image from input original image data, comprising: a memory section which stores data of a line including pixels of the original image data to be processed and a line including pixels to be used for an interpolating process therein; an angle-to-sine/cosine converting section which obtains an X component and a Y component where a pixel interval of the original image data is an oblique side based on a rotating angle; a coordinate searching section which calculates reference coordinates of the output rotation image for the original image using the X component and the Y component in order of input of the original image data; an interpolating section which executes an interpolating process when the reference coordinates are not present; and a rearranging section which rearranges converted data acquired in the interpolating process and outputting data of the output rotation image, wherein the angle-to-sine/cosine converting section, the coordinate searching section and the interpolating section process pixels upon reception of a timing pulse indicating a head of an image frame of the input original image.
