Abstract
The video signal processing circuit which analyzes video signals inputted from outside, performs conversion processing for image quality adjustment on the video signals based on a result of analysis, transmits those towards a video display unit includes: a feature value/maximum value calculation module which calculates a feature value that is a numerical value showing a degree of brightness of the video signals; a gradation conversion threshold value calculation module which calculates a threshold value regarding conversion of the gradation based on a threshold value calculation expression that is formed based on the feature value and a conversion coefficient set in advance; and a gradation conversion module which performs gradation conversion based on a linear function that increases linearly by taking a region of the gradation equal to or higher than the threshold value among the video signals as a target.
