Patent ID: 11544825

Abstract:
The present invention provides image processing apparatus, an image processing system and an image processing method, whereby the accuracy of evaluation can be improved. Image processing apparatus for correcting a captured image includes an image acquisition unit that acquires block pixels, an image conversion unit that converts the lightness/darkness, density, luminance and color space of the image based on the RGB values contained in the block pixels, and an output unit that outputs the converted image, and the image conversion unit further includes a binarization processing unit that binarizes the image, calculates the area ration of lightness and darkness in the image, and specifies the light and dark fields, a density conversion unit that performs conversion into wavelengths corresponding to the RGB values, a luminance conversion unit that performs conversion into luminance of the maximum wavelength that is visible to human eye, and a color-space conversion unit that performs conversion into HSV values representing a color space of color tones.
