摘要： An imaging array and a method of operating an imaging array are disclosed. The imaging array includes a plurality of pixel sensors. At least one of the pixel sensors includes a photodiode, and a transfer gate connecting the photodiode to a floating diffusion node, a reset circuit, and a buffer adapted to generate a voltage indicative of a potential on the floating diffusion node on a bit line. The imaging array also includes a signal generator and a controller. The signal generator controls the potential at which electrons in the photodiode well are transferred to the floating diffusion node well. The controller causes the transfer gate signal generator to lower the potential on the transfer gate during an integration period such that electrons will be transferred from the photodiode well to the floating diffusion node well if the photodiode potential is less than the floating diffusion node potential.

摘要： A pixel sensor.having a main photodetector and a parasitic photodiode and a method for reading out that pixel sensor are disclosed. The pixel sensor is read by reading a first potential on a floating diffusion node in the pixel sensor while the floating diffusion node is isolated from the main photodiode. The pixel sensor is then exposed to light such that the floating diffusion node and the photodetector are both exposed to the light. A second potential on the floating diffusion node is then readout while the tloaling diffusion node is isoiated from the main photodiode. After the first and second potentials are readout, a third potential on the floating diffusion node is readout. The main photodiode is then connected to the floating diffusion node, and a fourth potential on the floating diffusion node is readout. First and second light, intensities are determined from the.readout potentials.

摘要： A hybrid imaging array and method for using the same is disclosed. The image array includes a low-light imaging array and a color imaging array. The two imaging arrays can be utilized separately or in conjunction with one another. The low-light imaging array is optimized for night vision or situations in which the light levels are too low to allow a conventional color image to be formed by the color imaging array. The color imaging array is optimized for daylight or color photography. The low-light imaging array can be utilized in conjunction with the color imaging array to provide a color image with reduced noise.
