Abstract
An image pick-up device for producing a synthesized image signal having a wide dynamic range by partially exchanging a plurality of image signals from a solid state image sensing element in an image synthesizing unit ( ), said image signals being obtained by picking-up a subject moving on a bright background with different exposure amounts, including a synthetic unsuitable portion detecting unit ( ) for detecting a synthetic unsuitable portion by comparing said plurality of image signals picked-up with different exposure amounts, a synthetic unsuitable portion correcting unit ( ) for correcting a pixel signal of said synthesizing unsuitable portion to derived a corrected synthesized image signal, and a low pass filter ( ) for combining said corrected synthesized image signal from said synthetic unsuitable portion correcting unit with said synthesized image signal from said image synthesizing unit to derive a corrected synthesized image signal. An image obtained from the corrected synthesized image signal is not influenced by the movement of the subject and does not cause any feeling of strangeness as compared with a conventional photographic image.
