INPUT AND OUTPUT IMAGE PROCESSING METHOD AND APPARATUS USING PLURAL LOOKUP TABLE

摘要

PURPOSE: A method and apparatus for processing an input and output image using a plurality of look-up tables is provided to perform a plurality of processes different thereto in real time with respect to various areas of an inputted image. CONSTITUTION: A plurality of look-up tables(23) process an inputted image by different data, respectively. The number of look-up tables(23) is 2n(n=1,2,...) which is total storing cell number of a frame memory(24). The look-up tables(23) have each inherent number, and the numbers are stored in an intermediate memory(25). The intermediate memory(25) has a two dimensions storing area the size thereof is the same as the size of the frame memory(24), and stores n-bit data per each storing cell. The intermediate memory(25) stores look-up table number information of total 2n number for selecting minimum one look-up table out of the plurality of look-up tables(23) in accordance with the inputted image by information with respect to a using of a look-up table to each pixel of inputted image. If an image obtained by photographing an object by a camera(21) is inputted, the image is converted into a digital image by an analogue/digital converter(22).
