PROBLEM TO BE SOLVED: To perform, in real time, accurate resizing by downscaling image data.SOLUTION: An image signal generation device 400 comprises: a parameter generation unit 20 for dynamically generating a parameter; and an image signal generation unit 90 for repeating generation processing of generating an output image signal in response to each sampling signal. Each parameter includes a division ratio parameter corresponding to a ratio between a second period and a third period excluding the second period in a first period from time at which an immediately preceding timing signal is input to time at which an immediately following timing signal is input. The image signal generation unit repeatedly generates, in response to each sampling signal, a first weighting signal and second weighting signal of an image signal; and repeats, in response to each sampling signal, processing of using the first weighting signal for processing of generating an output image signal taking the sampling signal as a second sampling signal and processing of using the second weighting signal for processing of generating an output image signal taking the sampling signal as a new first sampling signal. |
