An image signal processing device (1) includes: a delay unit (10); a basic correction value output unit (20); and a corrected image data output unit (30). The basic correction value output unit (20) inputs the most significant 4-bit data G[7:4] among image data G1 [7:0] on the first frame outputted from the delay unit (10), inputs the most significant 4-bit data G[7:4] among image data G2 [7:0] on the second frame inputted to the delay unit (10), and outputs basic correction values (Dto D) corresponding to them. The corrected image data output unit (30) inputs G[7:0], G[7:0], and Dto D, and executes different processes when G[7:4] is equal to G2 [7:4] and when G[7:4] is not equal to G2 [7:4], so as to obtain the corrected image data G' [7:0] corresponding to the data (G[7:0], G[7:0]).
