Patent ID: 7428329

Claim:
A pickup image processing device for an electronic component mounting apparatus in which one or more electronic components adsorbed by one or more adsorption nozzles is imaged by a camera and appearance information and/or adsorption position information of the electronic component is detected based on a pickup image of the electronic component, the device comprising: a storage unit which stores parallax data indicative of a relationship between a height of the electronic component and component size or image magnification per pixel for every pixel of the pickup image; a component height data capture unit which captures means for capturing component height data with respect to the height of the electronic component actually imaged by the camera; and a parallax correction unit which corrects correcting means for correcting parallax of the pickup image by correcting the component size or image magnification per pixel for every pixel of the pickup image based on the component height data and the parallax data: wherein: a plurality of the electronic components absorbed by a plurality of absorption nozzles respectively are imaged within the same visual field by the camera; the component height data capture unit captures a plurality of component height data with respect to heights of the plurality of electronic components; and the parallax correction unit determines the pickup images of the plurality of electronic components in the visual field of the camera and corrects the parallaxes of the pickup images of the respective electronic components individually using the component height data and the parallax data corresponding to the respective electronic components.
