ABSTRACT:
An image sensing apparatus for converting an object image formed by a photographic lens into electrical signals includes a solid-state image sensor having an offset sampling structure for converting the image into electrical signals. An optical low-pass filter is positioned between the lens and the solid-state image sensor and includes at least two optical members each for splitting a light beam into plural light beams having two different propagation directions from each other.
