Patent ID: 7382402

Claim:
An imaging system comprising: an imaging device which outputs a plurality of digital signals each of which indicating an amount of light entered on a corresponding one of a plurality of pixels; a pre-processor which reduces an amount of data of the plurality of the digital signals output by said imaging device; a memory which stores digital signals; and a memory controller which writes the plurality of the digital signals output by said pre-processor in said memory, and reads the plurality of the digital signals from said memory; wherein said pre-processor comprises: a thinning out device which outputs a first control signal a level of which changes at a constant cycle to said memory controller; and an interpolation device which interpolates the plurality of the digital signals output by said imaging device; said pre-processor outputs the first control signal and the plurality of the digital signals interpolated by said interpolation device to said memory controller together; and said memory controller writes in said memory only a digital signal among the plurality of the digital signals interpolated by said interpolation device which the digital signal is input to said memory controller when the first control signal is at a predetermined level.
