1. An image capture condition adjustment device comprising
a hardware processor that acquires a plurality of captured images obtained by capturing a workpiece illuminated by an illumination device with a camera while moving at least one of the illumination device or the camera relative to the workpiece, and
adjusts an image capture condition for the camera in such a manner that distribution of brightness of an image is uniform for each of the plurality of captured images acquired, wherein
the hardware processor adjusts the image capture condition in such a manner that a maximum light amount of a dark area in a captured image is a constant value, that a minimum light amount of a light band is a constant value, or that an intermediate light amount between the maximum light amount of the dark area and the minimum light amount of the light band is a constant value.
