A data processing system has the following construction in order to achieve high speed data processing with reduced memory capacity. There are provided a memory to store a plurality of pieces of sequentially input data to be processed, a plurality of processors to execute a series of processings, e.g., Log conversion, MTF correction, gamma correction and binarization in this order to the data to be processed stored in the memory in the order of input, and a state control portion to determine which processing is stagnant by monitoring the progress of a processing by each of said plurality of processors and prohibit a processor executing a processing succeeding to a processing determined as being stagnant from accessing the memory. Processings by the plurality of processors are executed asynchronously and the plurality of processors share the memory.</PTEXT>
