  • Image processing apparatus for generating a warning according to dirt degree
    Patent number: 10523826
    Abstract: An image processing apparatus includes a processor for acquiring an image of a reference member, calculating a dirt degree at an imaging position by comparing a gradient value of a pixel with a gradient value of peripheral pixels of the pixel or comparing the gradient value of the pixel with a reference value, with regard to a pixel included in the acquired image of the reference member, and generating when the dirt degree is equal to or more than a first threshold. When the dirt degree is less than the first threshold and equal to or more than a second threshold that is smaller than the first threshold, the processor generates the warning only when a scan count exceeds a scan count threshold, and when the dirt degree is less than the second threshold, the processor does not generate the warning.
