  • Optically intelligent image sensing device
    Patent number: 8508674
    Abstract: An optically intelligent image sensing device is provided. By applying different potentials across different electrode sections in the image sensing device, the electric field profiles of the corresponding liquid crystal layer sections bend the lights passing through the liquid crystal layer sections in a predetermined manner. In one embodiment, all of a certain color light entering the image sensing device can be bent towards a color filter for the specific color, thereby entering the light sensor for the specific color light. Accordingly, the optically intelligent image sensing device has improved optical efficiency. An arrangement for an array of different electrode and light sensing sections in the image sensing device is also provided as an example for how each electrode may be connected to the optically intelligent image sensing device control signals. An example using the present optically intelligent image sensing device to improve the optical efficiency of an image capturing device is also described.
