Abstract
A reference image to serve as a reference for a non-defective determination is previously stored in association with identification information for identifying an inspection object. An image of the inspection object is displayed side by side with the reference image of corresponding identification information. A drawn position of the reference image and a drawn position of the acquired image are aligned, adjustment is made so as to make brightness of the reference image coincide with brightness of the acquired image, and adjustment is made so as to make a focus on the reference image coincide with a focus on the acquired image. Adjustment is made so as to make a focus of the reference image coincide with a focus of the acquired image.
Claims12
An image processing device, which is connected with an imaging unit for imaging an inspection object, and performs imaging processing on image data captured by the imaging unit, to make a defective/non-defective determination on the inspection object based on a result of the image processing, the device comprising:
- a reference image storing unit for storing a reference image to serve as a reference for a non-defective determination in association with identification information for identifying the inspection object;
- an image displaying unit for acquiring an image of the inspection object, to display the acquired image side by side with the reference image of corresponding identification information;
- an alignment unit for aligning a drawn position of the reference image and a drawn position of the acquired image;
- a brightness adjustment unit for performing adjustment so as to make brightness of the reference image coincide with brightness of the acquired image;
- and
- a focus adjustment unit for performing adjustment so as to make a focus on the reference image coincide with a focus on the acquired image.
An image processing method, which is executable by an image processing device, which is connected with an imaging unit for imaging an inspection object, and performs imaging processing on image data obtained by imaging by the imaging unit, to make a defective/non-defective determination on the inspection object based on a result of the image processing, the method comprising the steps of:
- storing a reference image to serve as a reference for a non-defective determination in association with identification information for identifying the inspection object;
- acquiring an image of the inspection object, to display the acquired image side by side with the reference image of corresponding identification information;
- aligning a drawn position of the reference image and a drawn position of the acquired image;
- performing adjustment so as to make brightness of the reference image coincide with brightness of the acquired image;
- and
- performing adjustment so as to make a focus on the reference image coincide with a focus on the acquired image.
