Claims
- 1. A method for identifying the presence of a logic state in a set of binary digital signals, the set of binary digital signals being suitable for characterizing a region of an image in terms of coloration, comprising steps of:selecting groups of the signals by address; examining the addressed signals to determine the presence of a first of two logic states, said examining being performed by processing groups of multiple ones of the signals concurrently by use of an OR function among groups of the signals for each of respective ones of characteristics of coloration; wherein the respective signal groups represent respective components of the coloration, the first of the two logic states designates the presence of a color component in a pixel of the image, and an outputting by the OR function of the first of the two logic states shows the presence of color in at least one of a plurality of the signal groups; and detecting, in an output of the OR function, a signal having the first logic state, a location of the signal in the region being known by the address of the signal.
- 2. A method for identifying the presence of a logic state in a set of binary digital signals, the set of binary digital signals being suitable for characterizing a region of an image in terms of coloration, comprising steps of:selecting groups of the signals by address; examining the addressed signals to determine the presence of a first of two logic states, said examining being performed by processing groups of multiple ones of the signals concurrently by use of an OR function among groups of the signals for each of respective ones of characteristics of coloration; detecting, in an output of the OR function, a signal having the first logic state, a location of the signal in the region being known by the address of the signal; changing a size of the region to a second region of smaller size; and repeating the steps of selecting, examining, and detecting for such ones of the signals as are found within the second region.
