| Number | Title | Issue Date |
| 4514760 | Digital television receiver with time-multiplexed analog-to-digital converter In a television (TV) receiver having digital signal processing in which the video and sound signals are separated in the analog processing circuitry, one analog-to-digital converter (ADC) serves both the video and sound signal paths. The analog video and ... | 04/30/1985 |
| 4434439 | Digital television AGC arrangement An automatic gain control arrangement is provided for an analog to digital (A/D) converter in a television signal processing system. A gain-controlled source of analog signals applies a video information signal to the input of an A/D converter. The A/D co... | 02/28/1984 |
| 4410876 | D.C. Stabilized analog-to-digital converter A D.C. stabilized analog-to-digital converter of the type having a coarse converter responsive to a supplied analog signal for converting the analog signal to a coarse digital signal representation thereof, a reconverter for reconverting the coarse digita... | 10/18/1983 |
| 4403253 | Uniform distribution video processor with controlled reference voltages A video processor that provides non-linear amplification of an input video signal by automatically modulating a non-linear transfer function of an amplifier having a plurality of piece-wise, analog-to-digital (A/D) converter sections. Each A/D converter h... | 09/06/1983 |
| 4400693 | MOS Parallel A/D converter For the dynamic compensation of the offset voltage in such converters each non-inverting comparator input (+) is connected via a first transfer transistor (T11, T12, T1p) to the signal input (SE) and via a second transfer transistor (T21, T22, T2p) to the... | 08/23/1983 |
| 4393452 | Method of reproducing a picture having improved resolution In a picture processing method, the density data of picture elements in a particular picture element region in a 4×4 arrangement which is provided by decomposing an original picture into a number of picture elements are subjected to n-base quantization t... | 07/12/1983 |
| 4276543 | Monolithic triple diffusion analog to digital converter A parallel analog-to-digital converter having high speed and high resolution, fabricated on a single integrated-circuit chip in such a manner as to avoid problems typically associated with high speed parallel converters. The converter disclosed by way of ... | 06/30/1981 |
| 4251802 | Analog to digital converter An improved analog to digital converter of the parallel or series-parallel type having expanded range for a given number of comparators in the quantizer. The converter is particularly adapted to convert analog signals, such as television signals, of a typ... | 02/17/1981 |
| 4244004 | Method for analog-digital conversion, and a picture reproduction method employing the same A method of analog-digital conversion is disclosed, wherein sub-sampling of an analog signal is performed at a certain multiple n of the basic sampling rate, and wherein from n consecutively-produced values representative of the analog signal the digital ... | 01/06/1981 |
| 4176376 | Image processing system An image processing system converts gradation data of an image signal from a television camera into a digital code and transfers it to a computer. In the image processing system suitable means slice a portion which contains data of the image signal at a g... | 11/27/1979 |
| 4163248 | Field sequential transmission of luminance and chrominance information Color T.V. signal information is transmitted from a receiver into a recorder, from a transmitter to a receiver, from a color T.V. camera into a transmitter, or the like. The luminance component and the chrominance component are alternately applied to an a... | 07/31/1979 |
