Abstract

Interpolating processes for vertically aligned horizontal scanning lines are performed with respect only to red component video data so as to simplify the structure of an image processor and to decrease the number of components that are required for interpolation. Interpolation is always performed for the green component video data, which makes up a great deal of the luminance component. Even when only green is interpolated, 59% of the total luminance component of yellow is interpolated so that flicker is reduced to a practical level.
