An optical vision chip and an image recognition method using the same are provided to perform an image recognition operation while not requiring complex mathematical equations or calculation by directly comparing an object image with a standard model image. An optical vision chip includes the first display element(10), the second display element(14), and an optical sensor(18). A size and a shape of the first pixel(12) of the first display element and the second pixel(16) of the second display element are overlapped with those of a sensor pixel of the optical sensor. The first display element displays an object image, and the second display element displays a standard model image stored at an external memory. When the second display element displays the standard model image, the brightness of the standard model image is a complement to the brightness of the object image. The optical sensor outputs an electric signal, which expresses an optical difference between the object image and the standard model image, via an electrode line. If the electric signal outputted by the optical sensor is sent to an external display unit, an optical difference of the image can be displayed. |
