According to the present invention, provided is an image capture device, an image processing method, and a non-transitory computer readable medium storing a program capable of detecting a direction of incidence of abnormal oblique incident light and reducing an effect of color mixture caused by the abnormal oblique incident light. An image capture device 10 includes an abnormal oblique-incident-light detection portion 34 and a correction portion 36. An abnormal oblique-incident-light detection portion 34 detects abnormal oblique incident light originated from a first direction by comparing the pixel data of first first-direction same-color adjacent pixels, second first-direction same-color adjacent pixels, first first-direction different-color adjacent pixels, and second first-direction different-color adjacent pixels.
