Abstract
A method of operating a solid state image sensor () for the acquisition of an image generated by an asynchronous stimulus (S) is described in which the sensor is operated in conjunction with at least one detector () which detects the said asynchronous stimulus. The sensor is regularly reset so as to commence integration from a reset state of the sensor each time a period Tr has elapsed. The output of the detector(s) prior to each reset (R) is used to determine whether that reset is inhibited or not, whereby the likelihood of the stimulus being corrupted is prevented, or at least substantially reduced. A method is also proposed in which a portion of the sensor array is itself used as the detector () for detecting the asynchronous stimulus. A solid state image sensor incorporating a reset inhibition control function for carrying out the described method is also claimed.
