Title:
ILLUMINATION CONDITION SPECIFYING DEVICE AND ILLUMINATION CONDITION SPECIFYING METHOD
Document Type and Number:
WIPO Patent Application WO/2018/055757
Kind Code:
A1
Abstract:
A CPU of a mounting device acquires an ideal image which is desired to be acquired by capturing an image of a component (Step S110), acquires a plurality of captured images acquired by capturing the component under different illumination conditions (Step S140), and performs a coincidence degree derivation process for deriving a coincidence degree between the ideal image and a captured image with respect to the plurality of captured images (Step S150). Further, the CPU specifies, as an illumination condition appropriate to capturing the component, an illumination condition at the time of capturing a captured image of which the coincidence degree can be considered the highest out of the plurality of the captured images (Step S170).
