A bowling pin detector illuminates all standing pins in a ten pin bowling game to produce a separately identifiable pin image for each pin regardless of the position of the pins with respect to each other. These pin images are sensed by a high resolution photosensitive surface such as exists in a video camera. The video output of the photosensitive surface is processed to generate a pin signal corresponding to each standing pin. To identify detected pins, the field of view is divided into pin identifying regions. The apparatus is programmed to associate each detected pin to a pin identifying region when the detected pin image for that pin falls within that region. Total pin count only is provided when more than one pin is standing in the same pin identifying region.
