Abstract
An image processing system includes one or more processors that select one target algorithm from evaluation algorithms, calculate an evaluation value indicating adaptation to image measurement using the target algorithm and one or more evaluation images corresponding to an evaluation lighting pattern for each evaluation lighting pattern, and determine a lighting pattern to be used for the image measurement from evaluation lighting patterns based on the evaluation value.
