  • Active pixel color linear sensor with line-packed pixel readout
    Publication number: 20020134917
    Abstract: A CMOS active pixel color linear image sensor is operable in line-packed readout mode, and at very high speed. In accordance with a preferred embodiment, the sensor is formed entirely on a single-chip and may be further configurable for operation in parallel-packed and/or pixel-packed modes. Line-packed pixel readout is accomplished by spreading same color pixel signal sampled values in storage elements across each of plural readout register arrays in a “cyclic” manner. Facility is introduced for starting the reading of a next pixel (e.g., R pixel 2) even before the previous pixel (R pixel 1) has been read out to increase the effective pixel readout rate.

  • Using cascaded gain stages for high-gain and high-speed readout of pixel sensor data
    Patent number: 6441357
    Abstract: A sampling and readout system including a cascaded stage charge amplifier samples, amplifies, and outputs pixel sensor data from an array of pixel sensors. The charge amplifier divides the gain into several gain stages. Each gain stage amplifies the pixel sensor data.

  • Smart column controls for high speed multi-resolution sensors
    Patent number: 6365886
    Abstract: Smarts are added to a CMOS active pixel color linear image sensor operable in any of parallel-packed, pixel-packed, and line-packed readout mode, to provide the added feature of variable imaging resolution operability. By combining decoder block functionality with shift selection logic to provide column selection adaptable for lowering the resolution of an imaging process, higher speed imaging is possible. Furthermore, the added functionality is implemented in a manner which does not unduly impact chip size. More importantly, the added functionality is compatible with, and in fact complements the specific architecture of an active pixel color linear sensor with variable readout mode functionality incorporated therein.
