Abstract
Official abstract text for this publication.
Apparatus and a method for correlated double sampling using an up-counter for parallel image sensors. All bits of a counter are set to one. An offset signal is compared to a first reference signal to define a first period during which the counter is incremented. After the first period, all bits of the counter are inverted. A sensor signal is compared to a second reference signal to define a second period during which the counter is incremented to generate a correlated double sampling value.
First claim
Opening claim text (preview).
What is claimed: 1. A method for correlated double sampling comprising: setting all bits of a counter; comparing an offset signal to a first reference signal to define a first period; incrementing the counter during the first period; inverting all bits of the counter after the first period; comparing a sensor signal to a second reference signal to define a second period; and incrementing the counter during the second period to generate a data value.…
