A filter for eliminating image errors, as well as associated method and TV signal display circuit, is provided to determine the filter coefficients according to the regularity of image errors in an image signal or a TV signal, thereby removing the image errors. The filter includes a plurality of multipliers and an adder. The multipliers receive a plurality of pixel values from a plurality of scan lines, multiply the pixel values by a plurality of corresponding weight coefficients and output the result; the adder sums up the outputs of the multipliers to generate an output pixel value. The errors have a regularity and the corresponding weight coefficients are associated with the regularity such that the errors of the pixel values may be canceled when the adder generates the output pixel value.

Filter and method for removing image errors and associated display circuit

A de-interlacing method and controller is provided. The de-interlacing method includes steps of de-interlacing based on an iodd input pixel row of an odd field and an ieven input pixel row of an even field to generate an iodd output pixel row, where i is a natural number; de-interlacing based on the ieven input pixel row and an (i+1)odd input pixel row of the odd field to generate an ieven output pixel row; and adjusting i and repeating the above steps to generate a complete interpolated frame.

De-interlacing method and controller thereof

An image processing circuit generating a frame according to a plurality of fields including at least first, second and third fields, comprises a memory unit and a de-interlacing unit. The memory unit stores the first and second fields. The de-interlacing unit receives the third field, and reads the first and second fields from the memory to generate a de-interlaced frame accordingly.
