A 360,000 pixel color image sensor for imaging photographic negatives

Abstract

We describe a 740(H) x 242(V) x 2 charge-coupled color image sensor for imaging photographic negatives. The sensor achieves charge capacity of 1 x 10 electrons per pixel, random noise of 300 rms electrons per pixel, and dynamic range of 70 dB. Sensor design, spectral sensitivity, charge capacity, and noise are discussed. SENSOR DESIGNThe imaging of color photographic negatives on television places a number of demands on a solid-state image sensor.

1/2-in 768(H)*492(V) pixel CCD image sensor

“…In the horizontal CCD (H-CCD) registers, a dualchannel read-out technique is employed for reading out signal charge [6], [7], so that the device is applicable to both the complementary color filter system and the RGBG primary color filter system. The dual-channel configuration does not require a notch filter to reject clock frequency component within the baseband frequency.…”
