    • CMOS image sensors are usually suffering from fixed pattern noise and random defect pixels. However, for economical reasons and in order to increase the manufacturing yield, some random defective pixels are usually accepted even for professional devices. In this case, the defect pixels are usually corrected by signal processing. A processing device (15) for correcting of at least one defect pixel value of an image sensor unit is proposed, the image sensor unit comprising at least a first and a second pixel array (1, 2, 3), wherein the image sensor unit is embodied to project the same image onto each pixel array (1, 2, 3), the processing device (15) comprising at least a first and a second input channel (11, 12, 13) for receiving pixel values of the first and the second pixel array, respectively, wherein the processing device (15) is operable to exchange the defect pixel value by a corrected pixel value, wherein the corrected pixel value is estimated by evaluating the values of neighbouring pixels of the defect pixel of the same pixel array, wherein the corrected pixel value is estimated by evaluating values of a corresponding pixel and its neighbouring pixels of the second pixel array at the same location as the defect pixel of the first pixel array in respect to the projected image.

    • The driving of an active matrix organic light emitting display (AMOLED) shall be improved. A pulsing grayscale rendition shall be combined with an improved motion rendition when driving the AMOLED with analog signals. Therefore, there is provided a data signal which is applied to each cell of the AMOLED for displaying a first grayscale level of a pixel of the image during a first group of sub-frames (SFO to SF5)for displaying at least a second grayscale level of a pixel of the image during at least a second group of sub-frames (SF' 0 to SF' 5). The first group of sub-frames (SFO to SF5) and the at least second group of sub-frames (SF' 0 to SF' 5) are constituting a video frame N. Each group of sub-frames is divided into a plurality of sub-frames. Each, the first group of sub-frames and the second group of sub-frames is belonging to a separate complete image of the display (AMOLED). The data signal of a cell comprises plural independent elementary data signals wherein each of the elementary data signals is applied to the cell during a sub-frame and the grayscale level displayed by the cell during the respective group of sub-frames depends on the amplitude of the elementary data signals and the duration of the sub-frames. With this concept, a flicker- free and a very high level of motion rendition can be offered.

    • The present invention relates to a grayscale rendition method in an active matrix OLED (Organic Light Emitting Display) where each cell of the display is controlled via an association of several Thin-Film Transistors (TFTs). In order to improve the grayscale rendition in an AM-­OLED when displaying low grayscale levels and/or when displaying moving pictures, it is proposed to split each frame into a plurality of subframes wherein the amplitude of the data signal applied to a cell of the AM-OLED can be adapted to conform to the visual response of a CRT display. According to the invention, the video frame used for displaying an image is divided into N consecutive subframes, with N≥2, and the data signal applied to the cell comprises N independent elementary data signals, each of said elementary data signals being applied to the cell during a subframe. The grayscale level displayed by the cell during the video frame is depending on the amplitude of the elementary data signals and the duration of the subframes.
    • 本发明涉及一种有源矩阵OLED(有机发光显示器)中的灰阶再现方法,其中显示器的每个单元通过多个薄膜晶体管(TFT)的关联来控制。 为了在显示低灰度等级和/或显示运动图像时改善AM-OLED中的灰阶再现,提出将每个帧分割成多个子帧,其中施加到该单元的数据信号的幅度 AM-OLED可以适应于CRT显示器的视觉响应。 根据本发明,用于显示图像的视频帧被划分成N个连续子帧,其中N≥2,并且施加到该小区的数据信号包括N个独立的基本数据信号,每个所述基本数据信号被应用于 子帧期间的小区。 在视频帧期间由单元显示的灰度等级取决于基本数据信号的幅度和子帧的持续时间。
