ABSTRACT:
Disclosed is an apparatus with an automatic detecting function for remaining pins in which the state of all of pins previous to the first bowl is photographed by a television camera from the upper front, image data of pins located at their fixed positions are set as reference data for each of the pins, and image data after the first bowl which are obtained by photographing the state of the remaining pins after the first bowl are compared with the reference data, to determine the presence or absence of the pins which are the objects to be measured for automatic scoring. It is the objective of the present invention to improve the accuracy in the measurement of the first pin. In the apparatus, the image data measurement points of the first pin are set at both sides of the head of the first pin, to thereby separate them from measurement points of the backward fifth pin.
