Document Type and Number:
WIPO Patent Application WO/2018/168571
Kind Code:
A1
Abstract:
This imaging device is equipped with a VF signal processing unit 15 which generates a second video signal having HD resolution by downconverting a first video signal having 4K resolution to generate a downconverted video signal having HD resolution, calculating the difference data from the average luminance value for each of the luminance values of a 2×2 pixel block in the center portion of a 4×4 pixel block region of the first video signal that corresponds to a 2×2 pixel block of the downconverted video signal, calculating an addition value for each pixel in the 2×2 pixel block of the center portion on the basis of the items of difference data, and individually adding the addition values to the luminance values of the 2×2 pixel block of the downconverted video signal.
