摘要： With regard to a subject block including a subject pixel and four adjacent blocks vertically and horizontally adjacent to the subject block, respective motion vectors of these blocks are considered as candidates of a pixel motion vector of the subject pixel. The block motion vectors are actually applied to the subject pixel, and one of the motion vectors that minimizes difference between pixel values of pixels used for inter-field interpolation is selected as the pixel motion vector of the subject pixel.

摘要： An FIR filter and setting method of filter coefficients thereof enabling the prevention of breakdown of equi-ripple of weighted approximation error and preservation of gain of the pass band into approximately constant. The setting method includes five steps. The initial setting step is that setting of the FIR filter, setting of the band, setting of coefficients of a pre-filter, and setting of initial extreme value point. The first step is that interpolation polynomial equation is generated for interpolating amplitude characteristic from the present extreme value point of the amplitude characteristic of the frequency. The second step is that a new extreme value point is determined from the amplitude characteristic obtained from the interpolation polynomial equation that is obtained in the first step. The third step is that judgement is performed whether or not position of the extreme value is approximated within required range while repeating the first step and the second step. The fourth step is that finding of the filter coefficients is performed from the approximated amplitude characteristic obtained in the third step.

摘要： To realize a motion compensation device capable of more appropriately compensating the movement of a video signal subjected to double-speed conversion. A motion vector between an image of a current field in a double-speed-converted video signal and an image of a reference field that is one frame or two frames later is detected, the pixels of the current field are shifted based on the motion vector and the pixels of the reference field are shifted in an opposite direction based on the motion vector. Then simple averaging or weighted average according to the shift amount is performed on the pixels of the current field and the pixels of the reference field to compensate the current field, thereby being capable of compensating the movement between fields so as to be much smoother than conventional cases.

摘要： Inter-field-interpolation spatial transition is calculated based on the sum of absolute values of differences between pixel values of an inter-field-interpolated pixel and adjacent pixels on the same field. Inter-field-interpolation temporal transition is calculated based on the sum of absolute values of differences between pixel values of the inter-field-interpolated pixel and pixels at corresponding positions on previous delayed field and present field. Intra-field-interpolation temporal transition is calculated based on the sum of absolute values of differences between pixel values of an intra-field-interpolated pixel and the pixels at the corresponding positions on the previous delayed field and the present field. The amounts of error in the interpolated pixels are calculated based on information of the inter-field-interpolation spatial transition, inter-field-interpolation temporal transition, and intra-field-interpolation temporal transition, and a pixel is generated by switching between inter-field interpolation and intra-field interpolation accordingly.
