摘要： System and methodologies are provided herein for de-interlacing a video sequence. Various aspects described herein can utilize a motion adaptive video de-interlacing algorithm based on block-based texture classification and a multi-level decision hierarchy to interpolate missing fields of an interlaced video signal in the spatial and temporal domains. In accordance with various aspects described herein, respective blocks of an interlaced video sequence can be classified by a texture classifier as “textured” or “non-textured.” Based on this classification, one or more motion detection schemes can be utilized to determine whether the respective blocks are static or moving. Missing pixels from one or more blocks can then be estimated using the texture and motion classifications based on values of neighboring lines and/or pixels in the field from which the block was obtained as well as values of corresponding pixel locations in temporally adjacent fields.

摘要： A video signal processing apparatus for outputting an output video signal to a display unit and displaying an image based on an input video signal on the display unit includes a signal processor for dividing the input video signal into a predetermined number of signals and outputting the signals as the output video signal. The signals as the output video signal drive associated areas obtained by dividing a display-capable area of the display unit. In accordance with the display unit, the predetermined number of signals is set so that the clock frequency of each of the signals output as the output video signal is less than or equal to a clock frequency that can be processed by the display unit.

摘要： A method of deinterlacing includes generating a deinterlaced display frame including a reference field of lines of display pixels of a first parity and a generated field of lines of display pixels of a second parity. A frame motion map is generated which includes bits representing a presence of motion or an absence of motion at the display pixels of the reference and generated fields. Testing is performed for the presence of motion or the absence of motion at a selected display pixel of the reference field utilizing the frame motion map. In response to detecting a presence of motion at the selected display pixel of the referenced field, replacing a pixel value corresponding to the selected display pixel with a pixel value generated by interpolating between display pixel values corresponding to neighboring display pixels in the generated field.

摘要： A method for processing a video signal and a video display apparatus using the method are provided. The video display apparatus compares a current video field to a previous video field two fields earlier than the current video field, detects motion information, and de-interlaces the current video field using the detected motion information. Therefore, it is not necessary to wait until the next video field is input in order to detect motion information regarding the current video field, and thus it is possible to prevent video delay.

摘要： In a video system, a method and system for control of a multi-field deinterlacer including visually pleasing start-up and shut-down are provided. During a hard start, a deinterlacer may deinterlace a first received field and provide the resulting frame for display until sufficient fields are received to generate a pixel constellation for deinterlacing subsequent received fields. The deinterlacer may also provide a constant frame for display until sufficient fields are received to generate the pixel constellation. During normal operation, the deinterlacer may mitigate the effects of a discrepancy as to the received field type. When a video source is jittery or there is uncertainty as to the field type, deinterlacing may be forced to be based on spatial information. When a video source is shut off, a portion of the remaining stored fields may be flushed. At least one of the flushed fields may be deinterlaced and displayed.

摘要： A de-interlacing system with an adaptive edge threshold has a motion factor generator to produce a motion factor of a position in accordance with a previous and a next fields. An adaptive edge threshold generator produces the adaptive edge threshold in accordance with a current, the previous and the next fields. A determinator determines which pixels are used to perform an interpolation on the position. When the motion factor is greater than the adaptive edge threshold, a pixel of the current field is used to perform an interpolation on the position. When the motion factor is smaller than the adaptive edge threshold, a pixel of the previous field and a pixel of the next field are used to perform an interpolation on the position.

摘要： Upsampling for video signals is described. In particular chroma pixels may be upsampled in a luminance, chrominance signal using motion adaptive approaches. In one example, the operations include selecting an absent chroma pixel of the current frame, developing a spatial candidate value for the absent chroma pixel using pixel values for nearby pixels in the current frame, developing a temporal candidate value for the absent chroma pixel using pixel values for nearby pixels in the previous and subsequent frames, computing a value for the absent chroma pixel by combining the spatial candidate value and the temporal candidate value, and producing an output video frame including the computed absent chroma pixel values.

摘要： An image signal processing apparatus having three processing portions. A first processing portion generates a motion class that corresponds to a target position in an output image signal based on an input image signal. A second portion generates a space class corresponding to the target position based on the input image signal and synthesizes the space class and the motion class to generate one class. A third portion selects multiple items of pixel data positioned in a periphery of this target position based on the input image signal and generates pixel data of the target position in the output image signal according to an estimate equation using the multiple items of pixel data and coefficient data corresponding to the class. These processing portions are respectively constituted of integrated circuits (ICs) having the same configuration. These ICs have first and second functional blocks. Each of the functional blocks changes its functionality according to setting.
