PROBLEM TO BE SOLVED: To provide a video signal processing device for displaying a portion including a predetermined luminance level range in a video image and a specific value of the predetermined luminance level range so as to easily grasp them.SOLUTION: The video signal processing device includes a function for displaying a video signal and a luminance waveform representing a relation between a luminance level included in the video signal and a position. The video signal is displayed while applying a predetermined color to a region 302 at a luminance level included in a preset luminance level range. On the other hand, the luminance waveform of the video signal is displayed while applying a color corresponding to the predetermined color to a region 303 corresponding to the luminance level range. |
