ABSTRACT:
A processing circuit for a digital camera system enables capture of a visual event which falls within some user-defined range. A digital camera converts a target image into a set of digital data signals, each signal representing the brightness level of a pixel in a matrix. A memory stores a mask also comprising a matrix of pixels. As the digital camera scans the target image, each data pixel from the camera is compared to a corresponding pixel in the mask and differences in brightness between the two are counted. When the count reaches some predetermined valve, the current frame of video data is saved for further analysis and/or display.
