Abstract
A display image correcting device including, retaining section configured to retain reference correction amount data for correcting nonuniformity as a predetermined factor of an image displayed on a basis of a video signal, the reference correction amount data representing an amount of correction at a predetermined horizontal and vertical position of the image, the amount of correction being obtained in correspondence with a video signal level as a reference, and correcting section configured to perform correction processing on the video signal in correspondence with a horizontal direction and a vertical direction of the image, and a brightness direction, and performing the correction processing on a basis of three-dimensional correction amount data obtained by making two-dimensional correction amount data corresponding to a horizontal and vertical position, the two-dimensional correction amount data being obtained on a basis of the reference correction amount data, linearly proportional or nonlinearly proportional to level of the video signal to be corrected.
