Claim:
An image processing system comprising: a camera for picking up a workpiece; and an image processing apparatus for capturing image pickup data of the workpiece picked up by said camera and performing image processing, said image processing apparatus including a trigger receiving section for receiving a trigger from an outside to initiate capture of workpiece image pickup data by said camera, a trigger generation section for generating a predetermined number of internal triggers at predetermined intervals via an interval timer after said trigger receiving section receives the trigger from the outside, each of the internal triggers initiating capture of workpiece image pickup data at the predetermined intervals, an image processing section for performing image processing with respect to each of the image pickup data picked up by the camera after receipt of the trigger from the outside and the internal triggers, and a statistical processing section for calculating variations between the image pickup data picked up by the camera after receipt of the trigger from the outside and the image pickup data initiated by the predetermined number of internal triggers and for determining abnormal image pickup data that deviates from a predetermined range and eliminating the abnormal image pickup data from the statistical processing.
