摘要：An image capture system is presented where the dynamic range of photoimaging devices, such as a still or video camera, is increased by varying sensor exposuretime on a pixel-by-pixel basis under digital camera processor control. The systems photo
sensors are continuously illuminated without reset over the exposure interval. In additionto being interrogated at the end of the exposure interval, the pixels are also non-destructively interrogated at one or more intermediate times during the interval. At eachinterrogation, the image capture system determines individually whether the pixels havesaturated and if not, the parameter value is recorded; if the pixel has saturated, thepreviously stored value from the preceding interval is maintained. To produce the finalsensor value for the whole exposure interval, the data for pixels that reached thesaturation level are adjusted to compensate for their shortened exposure.
