摘要： An object of the present invention is to provide an image processing apparatus capable of, at high speed, forming a half tone image exhibiting excellent linearity and gradation expressing characteristics while requiring only a simple structure. The image processing apparatus including a mean density calculating circuit for calculating a mean density in a predetermined region, a random number generator for generating random number data, an adder for adding, at a ratio corresponding to a level of input multivalue image data, the mean density obtained by said mean density calculating circuit and the random number data supplied from the random number generator, and a comparator for binary-coding the multivalue image data in such a manner that a value obtained by said adder is used as a threshold. To prevent roughness appearing in a highlight region in a binary-coded output image and obtain a satisfactory half tone output image exhibiting excellent gradation expressing characteristics, the mean density calculating circuit has a changing unit for changing the mean density.

摘要： The present invention is intended to solve a problem which may be encountered during a transfer from a mode for searching a desired still image to a mode for performing actual reproduction during the process in which still image information is reproduced from a tape-shaped recording medium on which a multiplicity of helical tracks are formed for one picture of still image information, one picture of still image information and address information indicative of the number thereof being recorded in the multiplicity of helical tracks. The sensation of an operator can be made coincident with an actually reproduced still image, for example, by effecting such mode transfer by detecting and using a number adjacent to a desired still image number or by shifting the tape-shaped recording medium by a predetermined amount. Accordingly, it is possible to to search a desired still image rapidly and easily.

摘要： A recording apparatus for recording a video signal on a recording medium together with data signals relative to the video signal comprises a first signal processing channel in which the data signals are supplied to a monitor in a state of being superimposed on the video signal, a second signal processing channel in which the data signals are supplied to the monitor without being superimposed on the video signal and a selector which selectively renders the first signal processing channel or the second signal processing channel operative. Where a display of the recording video signal on the monitor is excessively covered and hidden by that of the data signal, the second signal processing channel is selected and operated to permit adequate visual confirmation on the monitor of the video signal to be recorded.

摘要： In an image forming apparatus for forming a binarized image upon adding on additional information without degrading image quality, a mode signal assumes an "H" or "L" level. When the mode signal is at the "H" level, a pattern in which a binarized output attains the "H" level for two successive pixels appears in a low-density area of the image formed, thereby indicating the start of data representing additional information. When the mode signal is at the "L" level, additional information is represented by the level of a control signal f. The binarized output is controlled in such a manner that the spacing of black pixels becomes an odd number of pixels in a low-density area of the formed image in a case where the control signal f is at the "L" level and an even-number of pixels in the low-density area of the formed image in a case where the control signal f is at the "H" level. In other words, the additional information is expressed by indicating "0" when the spacing of black pixels is an odd number and "1" when the spacing of black pixels is an even number.
摘要翻译：在用于在不降低图像质量的情况下添加附加信息来形成二值化图像的图像形成装置中，模式信号呈现“H”或“L”电平。当模式信号处于“H”电平时，形成两个连续像素的二进制输出达到“H”电平的模式出现在形成的图像的低密度区域中，从而指示开始表示附加信息的数据。当模式信号处于“L”电平时，附加信息由控制信号f的电平表示。以这样的方式控制二值化输出，即在控制信号f处于“L”电平的情况下，黑色像素的间隔成为形成图像的低密度区域中的奇数个像素，在控制信号f为“H”电平的情况下，形成图像的低密度区域的像素数。换句话说，当黑色像素的间隔是奇数时，附加信息表示为“0”，当黑色像素的间隔是偶数时，表示为“1”。

摘要： An image signal reproducing apparatus includes a synchronizing signal generator which is configured so as to count the number of clocks of a generated clock signal, generate various kinds of timing signals in accordance with the result of count, compare the phase of the generated timing signal with the phase of an input synchronizing signal, and control a period to count the number of clocks of the clock signal in accordance with the result of comparison. It becomes thereby possible to form various kinds of correct timing signals even if the input synchronizing signal reproduced from a recording medium is deteriorated.
