ABSTRACT:
An image pickup device is provided which includes an image pickup unit, a fluctuation stabilizer, an exposure time controller, and a computing unit. The image pickup unit sends a video signal to the fluctuation stabilizer in which unnecessary fluctuations of the image output by the image pickup unit are stabilized depending on a stabilization reference value. The exposure time controller serves to control an exposure time used for the image pickup unit depending on the exposure time reference value. The computing unit functions to compute the stabilization reference value and the exposure time reference value. Such image pickup device produces an improved visually natural image.
