A scanning-type image display device includes: a light source section; a horizontal scanner; a vertical scanner, and a vertical scanner control section in such manner that, when a discrepancy occurs between a target scan line number and a scannable line number, and when a difference obtained by subtracting of the target scan line number from the scannable line number is a positive value, the vertical scanner control section controls the vertical scanner so as to put vertical scanning on standby within a time range from a point of time at which horizontal scanning is completed in a first frame to a point of time at which a horizontal scanning start signal corresponding to a vertical synchronizing signal of the video signal in a second frame is input, and restarts the vertical scanning in synchronization with an input timing of the horizontal scanning start signal.
