Abstract:
1. An image processing device for processing image data to be output through a screen, the device comprising: a memory configured to store input image data of at least one frame, the input image data having a plurality of coordinates; a read address calculator configured to calculate a read address, the read address being a coordinate of the plurality of coordinates chosen based on a transformation to be performed on the input image data through coordinate conversion; a memory interface configured to perform the transformation by reading the input image data from the memory as output image data without calculating addresses to read of the input image data but rather based on the read address provided by the read address calculator, the read address calculator being an integrated circuit separate from the memory interface; a memory access controller configured to, an image expander configured to expand the output image data read out from the memory to generate expanded image data so as to increase the number of pixels in the main scanning direction of the output image data to the number of pixels in the main scanning direction of the screen; and an image output configured to encode the expanded image data in the desired format and to output the encoded image data through the screen.
