Patent ID: 6891568

Claim:
A method for producing electronic video signals representative of color images of a scene, comprising the steps of: providing a luminance sensor and a color sensor having a color filter thereover, said color sensor having a two color checkerboard filter pattern; providing a pellicle beamsplitter, which is also operative as an acousto-optical low-pass filter, and providing a motion picture film camera type of lens system that focuses light from said image, via said beamsplitter, onto said luminance sensor and said color sensor; applying ultrasonic excitation to said pellicle to implement optical low pass pre-filtering of light from said image that is focused on said color sensor, said ultrasonic excitation being applied to said pellicle along diagonal directions with respect to vertical and horizontal reference directions of said color sensor to effect optical pre-filtering of the light focused on said color sensor; and producing electronic video signals from outputs of said luminance sensor and said color sensor.
