Abstract
There is provided with a filter processing device for performing a convolution operation using a filter on a feature plane. An acquisition unit acquires feature plane data, filter coefficients of the filter, and valid coefficient information which specifies filter coefficients to be used in the convolution operation among the filter coefficients of the filter. A calculation unit performs a convolution operation of the filter coefficients specified by the valid coefficient information and pieces of the feature plane data corresponding to the specified filter coefficients.
