  • Patent number: 11508331
    Abstract: The disclosure provides an image uniformity compensation device. The image uniformity compensation device includes a local pre-compensation circuit, a chromaticity uniformity compensation circuit, a local post-compensation circuit, and a luminance uniformity correction circuit. A local pre-conversion performed by the local pre-compensation circuit includes the following. An image frame is divided into multiple regions, and each of the regions is converted from an optical non-linear domain to an optical linear domain to generate a corresponding region in multiple regions of a converted frame. A local post-conversion performed by the local post-compensation circuit includes the following. An image frame is divided into multiple regions, and each of the regions is converted from the optical linear domain to the optical non-linear domain to generate a corresponding region in multiple regions of a converted frame.

  • Patent number: 9272285
    Abstract: The emulsification grinder includes a feeder module, a grinding wheel assembly and a driver module. The grinding wheel assembly separately connects the feeder module and driver module and includes an upper grinding wheel, a lower grinding wheel and a turntable. The upper grinding wheel is radially formed with knives. The lower grinding wheel corresponds to the upper grinding wheel at an interval and has a receiving room and knives. The turntable is received in the receiving room.
