Abstract:
1. A video signal processing device for converting an input first video signal to a second video signal, and inputting the second video signal to a display panel, the video signal processing device comprising: an inputter that receives an input of a set value of a signal level of the second video signal to be converted and output in correspondence to a signal level of the first video signal for each of a plurality of sample points of the signal level of the first video signal; a calculator that calculates interpolation of the signal level of the second video signal to be converted and output for the signal level between each of the sample points of the first video signal; and a controller that transfers a conversion table from the first video signal to the second video signal including a set value of the second video signal for each of the sample point of the first video signal and an interpolation value of the interpolation calculated second video signal between each of the sample points to a memory, wherein the memory converts to the second video signal of a corresponding signal level based on the transferred conversion table according to the signal level of the input first video signal, and outputs the second video signal.
