Abstract
An image processing apparatus includes: an imaging unit which generates workpiece images obtained by imaging a workpiece; and an image generation unit which generates an output image having a gradation value in a predetermined gradation range by converting the workpiece images sequentially input from the imaging unit. The image generation unit generates, for each of the input workpiece images, a gradation conversion condition for converting a first gradation value in the input workpiece image into a minimum gradation value in the predetermined gradation range and converting a second gradation value in the workpiece image into a maximum gradation value in the predetermined gradation range, and generates, for each of the input workpiece images, the output image having the gradation value in the predetermined gradation range by performing gradation conversion on each of the gradation values of the workpiece image using the gradation conversion condition corresponding to the workpiece image.
