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： When an image size is changed by using a linear interpolating process, a picture quality is improved so as not to overlap the position of an original signal and the position of an interpolation signal. An interpolation interval Vdp which is derived from an original image and an image size after the conversion is stored into a register of an input side and is accumulated and added by an adder from a register of an output side through a selector. A predetermined calculation is performed and an offset value q.sub.0 is obtained in a circuit. The value q.sub.0 is selected by the selector and the register of the output side is initialized for a vertical blanking period. Thus, a value (.delta.+nVdp) in which the value q.sub.0 was added to the accumulation value of Vdp is derived. On the basis of the value (.delta.+nVdp), a read address (n) of the original image and linear interpolation coefficients q.sub.n1 and q.sub.n2 are obtained. A similar process is also executed for the horizonal direction and an address (m) and coefficients p.sub.n1 and p.sub.n2 are obtained. A proper offset value is added to the interpolating position and the picture quality can be improved without overlapping the original signal and the interpolating position.

摘要： The invention provides an image processing apparatus and method as well as a providing medium by which deterioration of the vertical resolution is prevented and conspicuous appearance of line flickering is suppressed. In order to convert an interlaced video signal having 525 scanning lines into another progressive video signal having 525 scanning lines while maintaining the image size, in an odd-numbered field, a line after conversion is offset by 0.5 H (H is the distance between horizontal scanning lines of the inputted video signal). Consequently, pixel data of each line Oi are produced from pixel data of two lines Ii and Ii+1 before conversion. As a result, pixels of a line on the boundary between white pixels and black pixels have a gray color. In an odd-numbered field, no offset is given, and pixel data of each line I1 of the field before conversion are set as they are as pixel data of each line Oi of the field after conversion. The pixels of the line on the boundary between the white and black pixels become white or gray pixels, and consequently, when compared with an alternative case wherein such pixels on the boundary line are white and black pixels, line flickering is prevented from being observed conspicuously on a display screen.

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.

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.

摘要： 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.
