Abstract: A three dimensional system including additional 2 dimensional to three dimensional conversion.

Abstract: A method of pre-analyzing video signals obtained from a digital image stores the digital image in a frame buffer store in a specified video digital format. The amplitude, saturation and frequency of the stored digital image when converted into another video format, such as RGB or composite broadcast video, are each analyzed independently to identify areas of the stored digital image that might produce distortions in the final video format when displayed. Amplitude analysis is accomplished by converting the stored digital image into an RGB image, and each component is compared with predetermined limits to detect amplitude errors. Saturation analysis is accomplished by generating a saturation signal from the chrominance components of the stored digital image, and then comparing a function of the saturation signal with predetermined limits to detect oversaturation errors.

Abstract: A visible representation of a colored image is created on a print-receiving area by resolving the colored image into p raster lines and resolving each raster line into q pixels, and creating a succession of sequences of digital words such that each word is associated with a pixel of the image and has one of n possible values, representing the color of the pixel. Consecutive words in each sequence of digital words are associated with adjacent pixels in a raster line of the image and consecutive sequences in the succession of sequences are associated with adjacent raster lines. First, for each of the n possible values of each digital word, a measure of the number of words that have that value is determined. Second, a set of the n possible values is selected, such that the number yielded in the first step for each value is not zero. Third, a subset of the selected set is identified such that pixels having the colors represented by the values in the subset do not appear adjacent each other in the image.
