Image data circuit for correcting sensitivity differences between image sensors |
摘要 |
An image data circuit compensates sensitivity differences in image detection between a pair of image sensors. The image sensors each include a plurality of charge storage type optical sensing elements. Correction data indicative of sensitivity difference between the image sensors is stored in permanent memory. A clock pulse generator circuit generates clock pulses for counting charge storage periods indicated by output signals from the optical sensing elements. A pair of counter circuits counts the clock pulses and outputs count values corrected with the correction data and corresponding to the charge storage periods. A pair of quantizing circuits converts the output signals to image data based on the corrected count values.
