Patent number: 11128849Abstract: A video signal conversion device includes an RGB converter. The RGB converter converts gradation values of an input R signal, an input G signal, and an input B signal of three primary colors based on a conversion table or conversion formula to generate an output R signal, an output G signal, and an output B signal. The RGB converter, when it is designated, by a cataract degree designating signal that designates a degree of cataract including a degree of light scattering, that it is a cataract with light scattering, decreases the gradation values of the input R signal, the input G signal, and the input B signal, in a range from the minimum gradation value to a predetermined intermediate gradation value less than the maximum gradation value, with a linear characteristic of not converting gradation values as a reference.Type: GrantFiled: April 22, 2019Date of Patent: September 21, 2021Assignees: TOYO INK SC HOLDINGS CO., LTD., TOYO INK CO., LTD.Inventor: Takumi Ikeda
