摘要

PROBLEM TO BE SOLVED: To provide a depth data generation device and the like capable of generating a video signal of a pseudo stereoscopic image of higher accuracy from a video signal of a non-stereoscopic image without increasing a storage capacity.

SOLUTION: A color frequency detection unit 11 defines an angle range in a rotation direction whose center is the intersection of an X axis and a Y axis in a color difference plane as one color axis range, sets plural color axis ranges, and detects a color frequency indicating the appearance frequency of each pixel in each field or each frame of a video signal of a non-stereoscopic image included in each color axis range. A data processing unit 12 calculates a shift limit to be a limit of a shift amount in a shift amount characteristic set for each color axis range based on the color frequency, and sets the shift limit to the shift amount characteristic. Based on the shift amount characteristic and the saturation of each pixel in the video signal of the non-stereoscopic image, a depth data estimation unit 13 calculates a shift amount that is depth data of each pixel for each color axis range.
