Title:
IMAGING POSITION DETERMINATION DEVICE, IMAGING DEVICE, AND IMAGING POSITION DETERMINATION METHOD
Document Type and Number:
WIPO Patent Application WO/2024/075252
Kind Code:
A1
Abstract:
This imaging position determination device determines an imaging position of an imaging target inside a component mounting machine for mounting electronic components on a substrate. The imaging position determination device comprises: a defective pixel position storage unit that stores a position of a defective pixel of an imaging device for imaging an imaging target; a target region storage unit that, when an imaging center of the imaging device coincides with a specific position in the imaging target, stores a position of a target region, which is a region in which the imaging target is imaged within an imaging range of the imaging device; an allowable range specifying unit that, when the imaging center has been moved from the specific position of the imaging target, specifies an allowable range for the position of the imaging center at which it is possible to image the entirety of the target region stored in the target region storage unit; and a determination unit that, on the basis of the position of the defective pixel stored in the defective pixel position storage unit and the position of the target region stored in the target region storage unit, determines the position of the imaging center at which the number of defective pixels in the target region is smallest, among the allowable range specified by the allowable range specifying unit.
