Summary:PROBLEM TO BE SOLVED: To provide an image processing circuit that appropriately mounts a plurality of filter processes while suppressing an increase in circuit scale.SOLUTION: An image processing circuit for executing filter processing using a filter on image data, includes generating means that generates M (M: natural number) pieces of data of a filter tap from target data in the image data and a data group in a vicinity of the target data, a plurality of multipliers that hold coefficients of a predetermined number of bits, and setting means that assigns the coefficients to the M pieces of data of the filter tap generated by the generating means on the basis of filter coefficients constituting the filter.SELECTED DRAWING: Figure 1 【課題】回路規模の増大を抑制しつつ、複数のフィルタ処理を適切に実装することができる画像処理回路を提供する。【解決手段】画像データに対してフィルタを用いたフィルタ処理を実行する画像処理回路において、画像データに対してフィルタを用いたフィルタ処理を実行する画像処理回路において、前記画像データにおける注目データ及び注目データ近傍のデータ群から、フィルタタップのＭ（Ｍ：自然数）個のデータを生成する生成手段と、所定のビット数の係数を保持する複数の乗算器と、前記フィルタを構成するフィルタ係数に基づいて、前記係数を前記生成手段が生成したＭ個の前記フィルタタップのデータに割り当てる設定手段と、を備える。【選択図】図１
