Abstract
Computer simulated color images of a single-chip camera are subjectively evaluated with respect to both resolution and moire.
From the results of the evaluation, the color filter arrays with G-checkerboard pattern is selected and a composite 484 x 384 MOS imager with this color filter is fabricated.
The novel circuit design employed for the color imager prevents loss of resolution and reduces fixed pattern noise.
The measured performances of this single-chip color camera are ; (1) vertical resolution and horizontal resolution of 350 TV lines and 260 TV lines respectively, (2) signal to fixed pattern noise ratio of 47 dB in G channel with a condition of 14, 000 lx scene illumination and F : 2.8 iris number.
Although it is demonstrated that a resolution compatible with the home VTR is feasible, it is also stated that a significant gains must be made in optical sensitivity before this camera is put into practical use.
