Abstract
A video camera includes an image sensor. The image sensor repeatedly outputs an object scene image produced on an imaging surface having a plurality of pixels lined up in a vertical direction. A driver repeatedly executes an exposing operation for exposing the imaging surface for each pixel lined up in a vertical direction. A CPU repeatedly detects a plurality of luminance values respectively corresponding to a plurality of flicker evaluation areas allocated to the imaging surface in a manner to be located at positions different from one another in a vertical direction, based on the object scene image outputted from the image sensor. Moreover, the CPU determines the presence or absence of a flicker based on the plurality of luminance values thus detected.
