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.

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.

摘要:
An image sensing system is provided with a fluorescent lamp which performs AC lighting to irradiate an object, an inverter power source which supplies currents to the fluorescent lamp, a lighting frequency changing circuit which changes the frequency of the current supply, a lens which images an image onto a film, and a CCD image sensing device which is capable of changing the period of exposure by the formed image and which outputs the image of the object as an electric signal through photoelectric conversion. The exposure period of the CCD image sensing device is controlled by a microcomputer and a timing generator. The lighting frequency changing circuit is controlled so that the phase of the exposure period and the phase of the current supply to the fluorescent lamp are in synchronism with each other.

A recording method for recording on a recording medium by using an ink jet recording head having plural electrothermal converting members and discharging ink using thermal energy generated by the electrothermal converting members. The method involves measuring a driving ratio of the electrothermal converting members for each one line, determining a time period between termination of recording of a previous line and commencement of a recording of the next line in accordance with the driving ratio responsive to the next line measured in the measuring step, and allowing the next line to be recorded after passage of the determined time period.
