Abstract
A circuit device () includes a coordinate transform circuit () and a mapping processing circuit (). The coordinate transform circuit () performs coordinate transformation from an input coordinate (IXY) to an output coordinate (QXY). The mapping processing circuit () generates a second image (IMG) to be displayed in a display panel for displaying an image in a curved screen display by performing mapping processing on a first image (IMG) that is input based on the output coordinate (QXY). The coordinate transform circuit () performs the coordinate transformation from the input coordinate (IXY) to the output coordinate (QXY) by performing computation processing using a second or more order polynomial representing the coordinate transformation.
