Abstract
We developed a fast read-out circuitry for an a-Si:H image sensor with 128 columns and 96 rows. Reading out the columns partially parallel, we achieve an image frequency of up to 120 Hz. Noise has been kept ver y low, which renders in effect 7 bits of gray shade values. The indivi dual pixel characteristics are compensated by specifically assigned ga in and offset values, for which we propose a suitable computation algo rithm. Results showing the visual performance of the sensor are given. (C) 1998 Elsevier Science S.A. All rights reserved.
