An object is to provide an image processor that realizes a color conversion process appropriate for an image acquisition unit such as a scope and that can improve the accuracy of color reproduction. An image processor (1) is employed that includes a plurality of color conversion sections (115) an information acquisition section (250) that acquires an index for selecting at least one of the plurality of color conversion sections (115) as a specific color conversion means for applying a color conversion process to an input video signal and a selection section (251) that selects the at least one of the plurality of color conversion sections (115) as the specific color conversion means based on the index, in which the plurality of color conversion sections (115) include a linear color conversion section (202) that applies a color conversion process based on linear conversion to the input video signal and a table conversion section (203) that applies a color conversion process based on nonlinear conversion to the input video signal.
