Abstract: An image sensor that has a plurality of pixels within a pixel array coupled to a control circuit and to one or more subtraction circuits. The control circuit may cause an output transistor coupled to a pixel to provide a first reference output signal, a common reset output signal, and a first sense-node reset output signal, between which a subtraction circuit may form a weighted difference to create a noise signal. The control circuit may cause the output transistor to provide a second sense-node reset output signal, a light response output signal and a second reference output signal, between which a subtraction circuit may form a weighted difference to create a normalized light response signal. The light response output signal corresponds to the image that is to be captured by the sensor. The noise signal may be subtracted from the normalized light response signal to generate a denoised signal.

Abstract: An image system for converting an optical image of an object guided through an optical system (A1) into an electric signal by an amplification MOS sensor and processing the converted signal. The amplification MOS sensor includes a photoelectric conversion element (62) and an amplification MOS transistor (64) connected to the photoelectric conversion element (62). The sensor also has an output circuit and a noise elimination circuit (26, 28, 30, 32, 41). The output circuit amplifies a signal of the photoelectric conversion element (62) and outputs the amplified signal at a first timing, and outputs noise not relevant to the signal of the photoelectric conversion element (62) at a second timing. The noise elimination circuit has the same impedance as seen from the output circuit at the first and second timings and produces a difference between the outputs of the output circuit at the first timing and the second timing.

Abstract: Color and luminance measurement signals produced by the multiple sensors of a multiband (e.g. RGB color) image signal processing system are processed to reduce noise. For images such as those obtained from a multi-dye film, the luminance component of the output signal from the luminance sensor may be expressed as a function of the color components of the color sensor output signals. A first signal, representative of the constructed low frequency luminance signal, is produced as a linear function of the color sensor output signals, employing signal weighting coefficients derivable from intrinsic characteristics of the scanned image, such as the respective dye densities of a three layer color film. The luminance measurement signal derived from the luminance sensor is subtracted from this first signal, to produce a second signal, which is multiplied by a set of respective scaling factors, which are then subtracted from each color sensor output, so as to derive a set of noise-reduced estimates of the color components of each of the color sensor output signals. Each scaling factor is defined in accordance with the noise variances associated with the operation of the color image sensors and the luminance image sensor, and is proportional to a product of a corresponding one of the coefficients and the ratio of the noise variance associated with the operation of a respective color image sensor to a summation of the noise variances associated with the operation of each of the color sensors and the luminance sensor.

Abstract: A signal representative of the total incident flux on each area element (12-i) of a target plane (12) is generated. Each area element corresponds to a portion of the object (10) from which the flux emanates. Each total incident flux signal is corrected to eliminate therefrom the effects of flux incident on the corresponding area element due to scattering (24S1, 24S2, 28S1, 28S2), thereby to generate a signal representative of the flux incident on that area element emanating only from the portion of the object corresponding to that area element. The total incident flux signal is corrected by weighting (m) each total incident flux signal in accordance with a predetermined weighting factor W(x, y), and summing the weighted signal representative of the total flux incident on an area element with a weighted total incident flux signal from each of the other area elements.

Abstract: A five stage background filter circuit (10) which is capable of responding to background radiation changes at speeds which are from one to two orders of magnitude faster than conventional prior filter. The invention utilizes a cross can multiplexing technique in combination with filter circuitry depicted in schematic over view in (Fig. 1). Circuit (10) includes a differential amplifier (12), a sample and hold device (14), a responsivity corrector (16), a recursive filter (18), and a background subtractor (20). Output signals (11) from a focal plane array of detectors (Fig. 3) are passed through impedance matching input resistors (12a, b) to an amplifier. A sample and hold circuit (14a) cyclically selects and stores a signal received from first stage (12). The detector outputs are then normalized by responsivity corrector stage (16) which employs a digital-to-analog converter (16a) and random access memory (16c). A threshold band comparison and time-out logic circuit (21) within background subtractor stage (20) controls the operation of recursive filter stage (18) in order to suppress signals due to sensed radiation bursts and to eliminate the unwanted, dynamically varying background radiation portion of the signal present at node (17b). A processed output signal present at node (20i) is then passed to a target detection processor.
