PROBLEM TO BE SOLVED: To provide an image processing apparatus capable of reducing a processing burden by suppressing color blurring or low contrast, and a lane borderline recognition system.SOLUTION: An image processing apparatus (1) comprises: an image data acquisition unit (3) which acquires image data including an R pixel that holds a luminance value of red, a B pixel that holds a luminance value of blue, a G pixel that holds a luminance value of green and a C pixel that holds a luminance value of a wavelength region including red, blue and green; a discrimination unit (5) for discriminating whether a formula (1) of Valc-Valx<α is established regarding a luminance value Valx of a target pixel that is one of the R pixel, the B pixel and the G pixel, a luminance value Valc of the C pixel that is closest to the target pixel, and a constant α; and a correction unit (7) for correcting the luminance value Valx of the target pixel so as to be smaller than the luminance value Valc on the condition that the formula (1) is established.SELECTED DRAWING: Figure 1
