Abstract
An image inspection device which inspects the inspection target by images includes: an imaging part, which images the inspection target; a changing part, which makes the location of the inspection target with respect to the imaging part periodically and relatively change; and a control part, which makes the imaging part image the inspection target so as to acquire a plurality of images having different imaging conditions at a plurality of timings which is periodically repeated due to the relative changes and at which the inspection target is in a predefined location with respect to the imaging part.
Claims11
An image inspection device, which inspects an inspection target by images, comprising:
- an imaging part, which images the inspection target;
- a changing part, which makes a location of the inspection target with respect to the imaging part periodically and relatively change;
- and
- a control part, which makes the imaging part image the inspection target in a manner that a plurality of images having different imaging conditions are acquired at a plurality of timings which is periodically repeated due to the relative changes and at which the inspection target is in a predefined location with respect to the imaging part, and wherein the plurality of images are continuously acquired at each of the plurality of timings while changing the imaging condition,
- wherein after the control part makes the imaging part image the inspection target so as to acquire a first image which captures the inspection target in the relative changes, when the location of the inspection target with respect to the imaging part is changed by the changing part to the same predefined location as the time when the first image is taken, the control part makes the imaging part image the inspection target so as to acquire a second image which captures the inspection target in the relative changes in imaging conditions different from the conditions under which the first image is taken.
An image inspection method, which inspects an inspection target by images, comprising:
- a changing process, in which a location of the inspection target with respect to an imaging part which images the inspection target is periodically and relatively changed;
- and
- a control process, in which the imaging part is made to image the inspection target so as to acquire a plurality of images having different imaging conditions at a plurality of timings which is periodically repeated due to the relative changes and at which the inspection target is in a predefined location with respect to the imaging part, and wherein the plurality of images are continuously acquired at each of the plurality of timings while changing the imaging condition,
- wherein after the control process makes the imaging part image the inspection target so as to acquire a first image which captures the inspection target in the relative changes, when the location of the inspection target with respect to the imaging part is changed by the changing process to the same predefined location as the time when the first image is taken, the control process makes the imaging part image the inspection target so as to acquire a second image which captures the inspection target in the relative changes in imaging conditions different from the conditions under which the first image is taken.
A non-transitory computer-readable medium comprising an image inspection program, which inspects an inspection target by images and makes a computer implement:
- a changing process, in which a location of the inspection target with respect to an imaging part which images the inspection target is periodically and relatively changed;
- and
- a control process, in which the imaging part is made to image the inspection target so as to acquire a plurality of images having different imaging conditions at a plurality of timings which is periodically repeated due to the relative changes and at which the inspection target is in a predefined location with respect to the imaging part, and wherein the plurality of images are continuously acquired at each of the plurality of timings while changing the imaging condition,
- wherein after the control process makes the imaging part image the inspection target so as to acquire a first image which captures the inspection target in the relative changes, when the location of the inspection target with respect to the imaging part is changed by the changing process to the same predefined location as the time when the first image is taken, the control process makes the imaging part image the inspection target so as to acquire a second image which captures the inspection target in the relative changes in imaging conditions different from the conditions under which the first image is taken.
