Fig. 3. Reconfigurable retinomorphic vision sensor.
(A) Demonstration of image processing with three different operations (i.e., image stylization, edge enhancement, and contrast correction). These operations are realized by controlling the photoresponse of each pixel in the sensor by varying Vg independently. (B) Image stylization. (C) Edge enhancement. (D) Contrast correction. Original images correspond to the images to be processed by different operations. Experimental results by distinct convolution operations are compared with simulations. Photo credits: C.Y.
