Abstract
An image processing circuit executes filter processing using a filter with respect to image data. The image processing circuit includes a supply unit and a plurality of multipliers. The supply unit is configured to supply M (M: a natural number) pieces of data of filter taps from data of interest in the image data and a data group in a vicinity of the data of interest. Each of the plurality of multipliers is configured to hold a coefficient having a predetermined bit count and multiply one of the M tap data with the corresponding coefficient according filter coefficients constituting the filter. Each of the plurality of multipliers is allocated to the one of the M tap data based on an allocation rule related to the plurality of predetermined bit counts and the filter coefficients constituting the filter.
