Abstract
PURPOSE:To automatize the inspection of a circuit board and to recognize a target body at a high speed by performing subtraction between an image signal which is outputted by one image pickup device and delayed by an image matching means and an image signal from the other image pickup device. CONSTITUTION:The circuit board 1 where many chip components 2 are mounted is mounted on a movable table 3 and moves as shown by an arrow (a), lighting devices 8 and 9 project light which is collimated rectangularly on the board 1, and the image pickup devices 10 and 11 pick up images of the irradiated area Then the image signal outputted by the device 10 is converted by an A/D converter 12 into a digital image signal, which sent to a delay image memory 14; and the image signal outputted by the device 11 is converted similarly into a digital image signal, which is sent directly to an absolute value subtracting circuit 16. Here, the memory 14 delays the signal from the device 10 and sends the digital image signals of the same place picked up by the devices 10 and 11 at the time to a recognition means 15, which performs the subtraction between those digital image signals to recognize the contours of the components 2.
