するエリア外輝度補正手段と を備えたフリツカ除去装置。[Claims for Utility Model Registration] An image of a composite image with a frame configuration in which image data of a background image and image data of a character font pattern for superimposing are combined and the font pattern is superimposed on the background image. In a flicker removal device of an image processing device that forms data and converts the image data of the composite image into analog to form an interlace scan video signal, each background of a font area in which the font pattern of the composite image is inserted. intra-area brightness correction means for correcting the brightness of image data of a pixel according to brightness around each of the background pixels inside the font area; and an image of each background pixel near the font pattern inside the font area. A flicker removal device comprising: out-of-area brightness correction means for correcting the brightness of data so that the closer the vertical distance to the font pattern, the closer the brightness of the data is to the brightness of the font pattern.
