| Number | Title | Issue Date |
| 4776029 | Method of compressing image signals A method of compressing image signals comprises the step of dividing the image signals into main signals sampled at appropriate intervals and interpolation signals other than the main signals. As for said main signals, prediction encoding compression proc... | 10/04/1988 |
| 4776030 | Block quantizer for transform coding In a two-dimensional transform coding system, the transform coefficients are ordered according to the variance of the coefficients through a frame of coefficient blocks. Quantization bits are individually assigned to maximize the reduction in quantization... | 10/04/1988 |
| 4774579 | Apparatus for quantifying video images of light beams The present invention relates to a device which replaces a video image of a light beam with a quantized image, having contours corresponding to preset intensity percentages. The continuous analog video waveform is replaced by a stepped waveform, resulting... | 09/27/1988 |
| 4769644 | Cellular automata devices Noise and fault tolerant devices made of cellular automata are disclosed. Preferred embodiments include cellular automata with updating rules that set a cell to a first state if more than a threshold number of adjacent cells are in the first state and wit... | 09/06/1988 |
| 4755813 | Screening circuit for screening image pixels A programmable screening circuit with memory for storing at each address location both a pixel screen value and the memory address of the screen value for the next pixel to be screened, and a control including a latch pair for separating data from each me... | 07/05/1988 |
| 4723298 | Image compression technique An optical and electronic scan produces an image composed of binary value pixels. An automatic picture compression routine reduces the number of pixels in the image. A first stage four to one reduction in the number of pixels is achieved by treating each ... | 02/02/1988 |
| 4719504 | Method for converting an analog picture signal into an amplitude-discrete output signal In a circuit arrangement for converting an analog picture signal, which corresponds to consecutive fields, into an amplitude-discrete output signal, which, in a comparison stage, compares the picture signal to a plurality of reference values and produces ... | 01/12/1988 |
| 4707859 | Apparatus for high speed analysis of two-dimensional images Apparatus is disclosed for high-speed processing of a two-dimensional image using Cellular Array Processors arranged as parallel modules in a multi-level matrix. An array of photosensors is used to provide image intensity signals for each image pixel. Com... | 11/17/1987 |
| 4677479 | System for re-quantization of coded picture signals A coded picture signal re-quantization system, in which a parameter such as a variance or a mean value of picture element values in a region to be re-quantized is calculated on the basis of sub-sampled picture element values and, according to this paramet... | 06/30/1987 |
| 4578715 | Picture signal quantizing circuit A picture signal quantizing circuit for quantizing with respect to multiple levels an analog picture signal read from a document by converting it into a digital picture signal which has a plurality of bits. An AD converter is installed in the circuit whic... | 03/25/1986 |
| 4225885 | Method and apparatus for adaptive transform coding of picture signals A method and apparatus to reduce the redundancy for the transmission or storage of picture signals using transforms. The basis coefficients are arranged in a sequence and thereafter quantized in the customary manner. The basis coefficients obtained from t... | 09/30/1980 |
| 3999167 | Method and apparatus for generating character patterns Apparatus for generating a character pattern where the character pattern comprises a plurality of dots where certain ones of the dots fall within the character outline and others of the dots fall outside of the character outline, the apparatus comprising ... | 12/21/1976 |
