Abstract

Image data is accurately resized in real time by downscaling. An image signal generating apparatus includes a parameter generator that dynamically generates a parameter PM and an image signal generator that repeats processing of generating an output image signal Q in response to each sampling signal B. Each parameter includes a division ratio parameter DP. The division ratio parameter DP corresponds to a ratio of a second time period Tb and a third time period Tc other than the second time period Tb. The second time period Tb is a time interval until the generation of a sampling signal B n in a first time period Ta until input of an immediate timing signal A k+1 since input of a last timing signal A k . The image signal generator repeatedly generates a first weighted signal Wa and a second weighted signal Wb of the image signal in response to each sampling signal B n .
