Solution Overview

Problem

Existing processing systems face challenges in accurately specifying the imaging position of a processing target when holding and imaging are performed separately, leading to potential inaccuracies in capturing surface images.

Innovation Solution

A processing apparatus with a holding section and an imaging section that are positionally fixed relative to each other, allowing for precise imaging of the processing target's surface, where the holding section and imaging section can be fixed to the same or different members, and utilizing a camera with adjustable light blocking to ensure high-resolution imaging.

AI summary

A processing apparatus includes a holding section that holds a processing target, an imaging section that is positionally fixed with respect to the holding section, and images a surface of the processing target, and a control section that controls the imaging section to image the surface of the processing target in a state in which the holding section holds the processing target.
