Patent ID: 8223220

Claim:
An image processing device, comprising: image acquiring means for sequentially acquiring images generated by imaging a predetermined subject to be imaged; image processing executing means for executing, in each of sequentially-arriving processing periods, image processing on the image acquired by the image acquiring means; preprocessing execution result output means for outputting an execution result of preprocessing performed on the image in part of the sequentially-arriving processing periods, the image having been acquired by the image acquiring means before the part of the sequentially-arriving processing periods; and execution result holding means for keeping holding the execution result output by the preprocessing execution result output means at least until the execution result is output next time by the preprocessing execution result output means, wherein the image processing executing means executes the image processing by applying the execution result held in the execution result holding means to the image acquired by the image acquiring means, and after the execution result of preprocessing performed in parallel with the image processing during the execution of the image processing by applying the execution result held in the execution result holding means is output to the execution result holding means by the preprocessing execution result output means, the image processing executing means executes the image processing by applying the output execution result multiple times until the next execution result of preprocessing is output to the execution result holding means by preprocessing execution result output means.
