摘要： A method for color reproduction of a gray scale image, in which each gray scale is assigned a color value (x,y) and brightness (Y). The relation between gray scale and brightness continues monotonically and the assigned color values are selected from the environment (U) of a specified reference color (xR, yR).

摘要： An image processing apparatus includes an image processing unit, a counter, and a determining unit. The image processing unit processes image data between the first and second color values of an input image. The counter counts the generation frequencies of the respective color values of the input image and generates a histogram. After smoothing of the histogram the determining unit determines the first and second color values on the basis of the count result obtained by the counter.

摘要： An apparatus and method to produce a series of color images including an optical assembly (12) for receiving a visual image (19). The optical assembly (12) directs the visual image (19) to a first sensor (22) and a second sensor (24). The first sensor (22) is a high resolution monochrome digital sensor and the second sensor is a lower resolution color digital sensor. These two sensors produce a succession of frames at the same rate. The succession of frames are encrypted with a frame number and a time code. The two succession of frames are stored in a frame buffer (38). The color frame can be edited by a human operator using an editor (14) for resulting a list of monochrome frames, which are automatically edited in accordance with edited color frames by using the frame number and time code. The contents of the frame buffer (38) can be transferred to a mass storage device (50). The frame buffer (38) can also be transferred to a color rendering processor (44) for producing a composite image from the monochrome frames and the color frames.

摘要： ROGERS, BERESKIN \A PARR Inventors: Wilson Markle and Brian Hunt Title: Coloring a Black and White Signal Using Motion Detection. A method and apparatus for coloring a black and white film. The film is converted to video tape and the locations of edges of moving objects in frames of the video signal are used to develop a motion indicator key. The motion indicator key is used to reduce noise in the video signal without smearing motion and is used to assign colors to the black and white signal. For each scene of the black and white film, a color mask is produced for one frame. The adjacent frame is then colored the same as the initial frame except where motion is indicated. Where motion is indicated, a selected process assigns colors, for example based on direction of movement or grey levels of adjacent pixels. The new color mask thus produced is used as a reference for coloring the next frame. In this way the whole film may be colored, scene by scene. The color mask produced may then be combined with the black and white video signal to produce a colored video signal.

摘要： 2.1 In a video recorder with built-in teletext decoder, teletext is to be recorded in such a manner that it is possible to replay the teletext signal in several grey steps and also in colour. 2.2 The analog text signal obtained in the teletext decoder (10) is matrixed to form a grey-scale signal (Yg) which is supplied to the recording path (7) via a switch (S1, S2). 2.3 Especially a VHS video recorder including recording of a teletext signal for persons with hearing defects.
