Abstract
A digital camera has a sensor array which removes subject motion blur by monitoring the rate at which charge is collected by the individual sensors within the array during scene imaging. If the rate at which photons (80) are striking the sensor varies, then the brightness of the image which the sensor is viewing must be changing. When a circuit (68) built in the sensor array detects that the image brightness is changing, the amount of charge collected is preserved and the time at which brightness change was detected is recorded. Each pixel corresponding to each sensor where exposure was stopped is adjusted to the proper exposure by linearly extrapolating the exposure the sensor did receive so that the pixel corresponding to the sensor has an intensity corresponding to the dynamic range of the entire image. The image sensing array will preferably be implemented as active-pixel sensor CMOS image sensors.
