  • Publication number: 20210272276
    Abstract: A benign tumor development trend assessment system includes an image outputting device and a server computing device. The image outputting device outputs first/second images captured from the same position in a benign tumor. The server computing device includes an image receiving module, an image pre-processing module, a target extracting module, a feature extracting module and a trend analyzing module. The image receiving module receives the first/second images. The image pre-processing module pre-processes the first/second images to obtain first/second local images. The target extracting module automatically detects and delineates tumor regions from the first/second local images to obtain first/second region of interest (ROI) images. The feature extracting module automatically identifies the first/second ROI images to obtain at least one first/second features. The trend analyzing module analyzes the first/second features to obtain a tumor development trend result.

  • Patent number: 10923081
    Abstract: A timing controller, a display apparatus, and an operation method thereof are provided. The display apparatus includes a display panel and a timing controller. The timing controller includes a refresh mark controller and a pixel controller. The refresh mark controller includes a refresh mark table, and a plurality of refresh marks in the refresh mark table correspond to a plurality of sub-regions of a display region in the display panel. The refresh mark controller determines whether the sub-regions need to be refreshed according to an image signal and responds to a specific sub-region required to be refreshed to adjust a specific refresh mark according to a mapping ratio. The pixel controller sequentially looks up whether the refresh marks in the refresh mark table are adjusted, obtains the sub-regions corresponding to the adjusted refresh marks according to the mapping ratio, and performs a pixel refresh operation to the sub-regions.

  • Publication number: 20120086731
    Abstract: A bistable electro-optic display device and a driving method thereof are provided. The display device includes an overlap detection unit and an overlapping image processing unit. The overlap detection unit compares a first display data and a second display data received by a pixel unit. When a first update region corresponding to the first display data overlaps a second update region corresponding to the second display data, the overlap detection unit outputs an overlapping display data, so as to make a display panel display the first update region and the second update region. The overlapping image processing unit combines the first display data and the second display data according to the comparison result and an overlapping display mode to output the overlapping display data to the overlap detection unit, wherein the overlapping display mode indicates the display priority of the first display data and the second display data.

  • Publication number: 20100214253
    Abstract: A method and an apparatus adapted to a capacitive touch panel for drift compensation are provided, wherein the touch panel includes a plurality of sensors. In the method for drift compensation, a plurality of capacitances respectively sensed by each of the sensors are extracted. Whether the touch panel is in a proximity state is determined upon a slope of the sensed capacitances and a slope parameter. Whether each of the capacitances is drifted is determined upon the capacitance and an allowable noise range. When the touch panel is not in the proximity state and each of the capacitances is drifted, each of the capacitances is compensated according to a drift error of each of the capacitances after a first presetting time has passed.
