Abstract
In an imaging apparatus, at least one picture division signal is generated. Every picture represented by a video signal is divided into at least first and second areas in response to the picture division signal. Detection is made as to a mean luminance of the first area and a mean luminance of the second area. A flicker in the first area is corrected to derive a first correction-resultant area in response to the mean luminance of the first area. A flicker in the second area is corrected to derive a second correction-resultant area in response to the mean luminance of the second area. The first correction-resultant area and the second correction-resultant area are combined into a correction-resultant picture.
