IMAGE PROCESSING APPARATUS AND LANE PARTITION LINE RECOGNITION SYSTEM INCLUDING THE SAME

摘要

In an image processing apparatus, an image data acquisition unit acquires image data including R-pixels which are red pixels, holding red luminance values, B-pixels which are blue pixels, holding blue luminance values, G-pixels which are green pixels, holding green luminance values, and C-pixels which are clear pixels, holding luminance values in a wavelength range including wavelength ranges corresponding to red, blue and green. In the apparatus, a determination unit determines whether or not an inequality given by Valc−Valx<α is satisfied, where Valx is a luminance value of a pixel of interest that is one of the R-, B-, and G-pixels in the image data, Valc is a luminance value of the C-pixel or pixels closest to the pixel of interest, and α is a constant, and if the inequality is satisfied, a correction unit corrects the luminance value Valx to be less than the luminance value Valc.

主权项

1. An image processing apparatus comprising:
an image data acquisition unit configured to acquire image data including R-pixels which are red pixels, holding respective red luminance values, B-pixels which are blue pixels, holding respective blue luminance values, G-pixels which are green pixels, holding respective green luminance values, and C-pixels which are clear pixels, holding respective luminance values in a wavelength range including wavelength ranges corresponding to red, blue and green; a determination unit configured to determine whether or not an inequality given by Valc−Valx<α is satisfied, where Valx is a luminance value of a pixel of interest that is one of the R-pixels, the B-pixels, and the G-pixels in the image data, Valc is a luminance value of the C-pixel or pixels closest to the pixel of interest, and α is a constant; and a correction unit configured to, if the inequality is satisfied, correct the luminance value Valx of the pixel of interest to be less than the luminance value Valc of the C-pixel or pixels.
