    • 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.
    • 由原始图像和转换图像的图像尺寸获得的插值间隔Vdp由加法器累积。 在奇数场中,选择器选择[0.5]作为与奇数/偶数场确定信号相对应的偏移量。 在偶数场中,选择器选择[0]作为与奇数/偶数场确定信号相对应的偏移量。 在垂直消隐间隔中,选择偏移量作为输出。 因此,在奇数场中,偏移值[0.5]被加到Vdp的累积值。 此后,再次累积Vdp。 对应于累积值,获得行读地址n和线性内插系数qn1和qn2。 当Vdp被累积时,相加于奇数场和偶数场中的扫描开始点的偏移量相加。 因此,保持隔行精度。

    • A picture processing apparatus and method for enlarging and reducing a picture wherein when a picture is reduced, horizontally adjacent pixel data is supplied from a delaying device to a horizontally interpolating circuit. With the pixel data, a coefficient p and a 1's complement (1-p) thereof supplied from an interpolation coefficient circuit, an interpolating process in the horizontal direction is performed. In addition, a pixel at the position of p=1 is thinned out. Pixel data that has been interpolated in the horizontal and vertical directions and that has been thinned out is written to a memory. When a picture is enlarged, pixel data that is read from a memory is delayed by two line memories and two adjacent pixels are properly selected by a switch circuit. A vertically interpolating circuit performs an interpolating process in the vertical direction. When pixel data is read from the memory, particular pixel data is read twice depending on a magnification. In the horizontal direction, likewise, an interpolating process is performed in the similar manner and an enlarging process is performed.

    • A picture processing apparatus for picture-in-picture applications where the number of pixels n in the horizontal direction of an original picture, the number of pixels m in the vertical direction thereof, the number of pixels N in the horizontal direction of the converted picture, and the number of pixels M in the vertical direction thereof are supplied to a dividing device. Thus, ratios A=N/n and B=M/m are obtained. The inverse number 1/A of the value A is cumulated by circuits. An address generating circuit generates addresses at four points for calculating a density value a of a converted pixel corresponding to the integer part of a cumulated value &Sgr;(1/A). These addresses are supplied to memories. The pixel data at the four points that are read from the memories are supplied to respective multiplying devices. The decimal part of the value &Sgr;(1/A) is supplied as an interpolating coefficient p to a multiplying device. A coefficient (1−q) is supplied to a multiplying device. Likewise, in the vertical direction, coefficients q and (1−q) are supplied to respective multiplying devices. These multiplying devices and adding devices perform operations. Thus, the density value a of the converted pixel is obtained and supplied from a terminal.
