Abstract
A filter for use with a CCD imager has vertical color stripes that have a non-integral relationship to the CCD sensors. A means for controlling the amount of a particular color that falls on a particular photosensor suppresses undesired signals.
Claims8
A filter for use with an image pick-up device having a plurality of columns of photosensors, said filter comprising:
- a plurality of vertical color filter stripes arranged in horizontally repeating cycles of color order and having a non-integral relationship with respect to said columns of photosensors;
- and means for controlling the amount of a particular color impinging upon a particular photosensor such that the fundamental and reduced undesired harmonics of the beat frequency between said columns and said stripes are generated in the resulting color signals from said photosensors.
