Abstract: A linear pixel-array processing systems uses a combination of digital and analog signal processing techniques to calibrate the gain and offset of each pixel in the analog domain. A plurality of fixed gain and offset values are applied in the analog domain to adjust the gain and offset of each pixel at high speeds (on the order of 25–50 MHz). By adjusting the gain and offset in the analog domain, the dynamic range of pixel conversion is improved such that the conversion range is fully utilized (over 90%, on the order of 95%–99%). The gain and offset values are determined with an algorithmic calibration routine that corrects for non-ideal effects in the signal path. A single processing channel can be multiplexed to process multiple pixel arrays to provide for a cost effective solution. In higher speed systems, the single processing channel can be extended to multiple processing channels for improved throughput.

Abstract: A correlated double sampler (CDS) circuit having a ping/pong architecture which employs only a single amplifier, and a CCD image sensor output processing circuit including such a CDS circuit and preferably also an analog-to-digital converter for processing the output of the CDS circuit and a black level correction feedback loop. In one cycle of operation (during processing of the raw output of a CCD sensor), the CDS circuit receives a first set of control signals followed by a second set of control signals, its output signal in response to the first set is indicative of the value of one pixel of a sensed image, and its output signal in response to the second set is indicative of the value of the next pixel of the image. Preferably, each set of control signals consists of a clamp signal, a sample signal, and a hold signal.

Abstract: A structure and a method are provided to receive a high-impedance reference voltage signal and generate a desired output signal that is capable of sourcing enough current to meet the demands of a fixed-resistance load. In such a circuit, the signal from an accurate, wide output-swing voltage source circuit having low quiescent current is combined with the output of a current source circuit so that the voltage input to the load is maintained even as the necessary current is supplied. The current source circuit preferably includes a tracking resistance that sinks a control current which a current mirror multiplies by the same ratio as that between the tracking resistance and the load resistance.

Abstract: There are disclosed electronic imaging systems employing CCD imaging units and one or more unique analog signal processors (ASP's). Each ASP receives color-component image signals from the CCD unit and provides respective output image signals, such as red, green and blue color components, having proper white balance for combining into a full color image. The dark background or zero level of the output image signals is referenced to a common "dark" reference voltage to minimize dark background variations in the combined color image regardless of the gain setting of the ASP or ASP's. Each ASP is substantially identical and has a unique architecture which facilitates its implementation as an integrated circuit. The ASP has a dynamic range of substantially better than 8-bits and provides for a wide range of signal sample rates (e.g., 1 to 40 MHz).
