Abstract:
1. An image-processing device that performs image processes for pixel data of an image to generate image-processed data, the amount of which is greater than that of said pixel data, for each line of said image, said image-processing device comprising: a memory that has a recording area in which said pixel data are stored, the capacity of said recording area for one line's worth of said pixel data being coincident with a maximum amount of data in one line of said image-processed data; a storing processor that stores said pixel data corresponding to one line in said recording area such that a last pixel data in a sequentially stored series of pixel data for said one line is stored at an end address of said recording area; and an image-processing processor that reads out said pixel data in ascending order of addresses of said recording area to perform said image processes to obtain said image-processed data, and stores said image-processed data in ascending order of addresses in said recording area, wherein said memory is provided with an offset area at a side of said recording area having a smaller address, said offset area being an area in which said pixel data are not stored, the capacity of said offset area being obtained by subtracting a first amount of data in said one line of said pixel data and a second amount of data corresponding to a number of pixels necessary to perform said image processes, from said maximum amount of data.
