  • Patent number: 11893746
    Abstract: The present disclosure describes an image processor of a display device. The image processing includes a pre-processor, a segmentation processor, and a correction processor. The pre-processor performs spatial filtering on an input image signal and output a line image signal. The segmentation processor classifies a class of the line image signal and outputting a segmentation signal representing the class. The correction processor corrects the segmentation signal based on the line image signal. Additionally, the correction processor detects a class boundary of the segmentation signal, detects an edge within an edge region of the line image signal corresponding to the class boundary, and corrects the segmentation signal based on the detected edge.

  • Publication number: 20230268933
    Abstract: A data processing device includes an average correction processor that corrects input data based on an average value of the input data and outputs average correction data, and reversibly encodes and decodes the average value to generate a decoded average value, an irreversible encoder/decoder that encodes and decodes the average correction data and outputs first and second decoded data, a binary predictor that predicts a magnitude of a restoration error included in the second decoded data based on the first decoded data and the decoded average value and outputs a prediction result as binary data, an error estimator that outputs an estimation error based on the first decoded data, the second decoded data, and the decoded average value, and an operation circuit that outputs output data based on the second decoded data, the binary data, the estimation error, and the decoded average value.

  • Patent number: 6891163
    Abstract: In order to prevent destruction of a read gate by excessive storage of charge without any addition or change to the manufacturing process, the array type X-ray detection apparatus using a direct conversion system, which directly converts irradiation X-rays to charge, provides each pixel cell with a sensor section for converting X-rays to an amount of charge according to the amount of X-rays, a charge collecting electrode for storing the charge generated, a read gate for transferring the stored charge to an external read amplifier and a MIS diode using a TFT. A clamp signal is applied to one end of the MIS diode. The read gate and MIS diode are formed in the same manufacturing process. Since the amount of charge stored in the charge collecting electrode is clamped to the amount of charge corresponding to the clamp signal voltage by the MIS diode, the read gate is not destroyed even with excessive X-ray irradiation.
