摘要： An image signal processing unit includes a frame rate conversion circuit performing double frame rate conversion on an input image signal from a first frame frequency to a second frame frequency. When performing frame rate conversion with the motion correction process, a motion vector is determined between a first frame image and a third frame image, and three interpolation frame images are formed through the motion correction process to the first frame image based on the motion vector, and are inserted between the first and third frame images so as to establish the second frame frequency. When performing frame rate conversion without the motion correction process, an interpolation frame image same as the first frame image is inserted between the first and second frame images, and an interpolation frame image same as the second frame image is inserted between the second and third frame images.

摘要： There is provided delay means for allowing a delay difference to be provided between the timing of image size information which is set into writing side memory control means and the timing of image size information which is set into reading side memory control means in a manner such that the image size when data is written into first and second field memories and the image size when the data is read out from the first and the second field memories coincide. The image size information is set into the writing side memory control means and the reading side memory control means so as to have a delay difference between them. The image size is set by controlling the first and the second field memories in accordance with the image size information by the writing side memory control means and the reading side memory control means. A switching control of every field is performed in a manner such that while the writing process is performed to one of the field memories, the reading process is performed to the other field memory.

摘要： An interpolation interval Vdp obtained by the picture sizes of the original picture and the converted picture is cumulated by an adder. In the odd field, a selector selects [0.5] as an offset corresponding to an odd/even field determination signal. In the even field, the selector selects [0] as an offset corresponding to the odd/even field determination signal. In a vertical blanking interval, the offset is selected as an output. Thus, in the odd field, the offset value [0.5] is added to the cumulated value of Vdp. Thereafter, Vdp is cumulated again. Corresponding to the cumulated value, a line read address n and linear interpolating coefficients qn1 and qn2 are obtained. When Vdp is cumulated, offsets corresponding to the scanning start points in the odd field and the even field are added. Thus, the interlace accuracy is kept.
