CORRELATED DOUBLE SAMPLING |
摘要 |
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.
