Abstract: An apparatus and a method for the recognition of colors on a colored image illuminated with a light source of a known spectrum composition, wherein the intensities of three primary colors are measured opto-electronically as color components, which represent the spatial co-ordinates of the color locations in a color space. Prior to color recognition the color components of at least one characteristic test point in each color or color region, which is to be recognized, are measured and noted. The test color components represent the corresponding test color locations in the color space. An identification symbol is assigned to each color component triplet of the test points and noted too.

Abstract: Apparatus and a method for converting patterns for weaving into stored information by scanning according to a scanning raster the pattern and determining the number of steps per stitch of the scanning raster by using the quotient of the dimensions of the scanned pattern divided by the number of stitches in the same direction and wherein such quotient is used such that at equality or upon a known deviation from a prescribed fraction of a step a signal is generated which indicates the beginning of the next stitch and wherein a greater deviation than said prescribed one the signal is given after a further step has been accomplished.

Abstract: A process for the identification of a predetermined plurality of colors on the surface of an object which is scanned by electrical-optical means to produce measured signals substantially representing the colors red, green, and blue coordinates, the plurality of colors defining color-regions, and defining color-identification-regions, wherein the boundaries of the identification-regions are simulated electronically through threshold-value circuits for each of the coordinates, the output signals of which are transferred to coincidence circuits, which indicate the presence of one of the plurality of colors when the coordinates of the color signals lie within the color-identification-region.
