Abstract
A light source drive control device includes: an image data generating part that generates line-thinned image data having been subjected to line thinning processing for thinning an edge pixel in image data by a first pixel width; an intensity information generating part that generates intensity information including a first intensity at which a pixel not included in a set second pixel width of an edge in the line-thinned image data is exposed and a second intensity at which a pixel included in the second pixel width is exposed and which is higher than the first intensity; and a light source driving part that drives a light source based on a light source modulation signal generated according to the line-thinned image data and a drive current data switched based on a drive current switching signal generated based on the intensity information.
