Title: Solid state camera having plural image sensors
Inventor: YAMANAKA S
IPC: H04N9/04
Filed: 1975-05-06
Granted: 1981-12-08
Abstract: Two charge coupled devices (which will be referred to as CCD chips) are employed in a solid state camera system wherein color filters, each consisting of horizontally extended color stripe filter elements, are disposed in front of the respective CCD chips.  Object images are projected onto the respective CCD chips through the color filters such that the object image on one CCD chip is shifted by τH/2 (where τH is the alignment pitch of picture elements in the direction of horizontal scanning) relative to the object image on the other CCD chip.  To read image information from the CCD chips, the read-out timing as between the two chips is different by τH/2 to compensating for the image displacement of the chips.

Title: Color imaging device
Inventor: OZAWA NAOKA
IPC: H04N9/04
Filed: 1982-02-01
Granted: 1988-05-30
Abstract: A false signal is detected when low correlation exists between adjacent picture elements in the vertical direction, the signal appearing in a boundary region in that direction.  A colour signal is then demodulated using the correlation between elements in the horizontal direction.  For low correlation in the horizontal direction, vertical element correlation is similarly used. The demodulation mode is controlled by a circuit switching the demodulator input depending on the output of detector circuits. These detectors from the synthesised luminance signal, in which direction a max. change in luminance occurs.
