Abstract:
A conditional correlated multiple sampling (CCMS) single slope (SS) analog-to-digital converter (ADC) is provided. The CCMS SS ADC includes a comparator, arranged to compare an analog signal with a ramp signal and generate a comparison result; and a CCMS control circuit, arranged to determine a swing of the ramp signal according to a magnitude of the analog signal. An image sensor system using the CCMS SS ADC and a method of CCMS SS analog-to-digital conversion are also disclosed.

Claim (Index 7):
An image sensor system, comprising:\n a pixel array, comprising a plurality of pixel cells arranged into rows and columns; an analog-to-digital converter (ADC) coupled to the at least one pixel, the ADC comprising: a control circuit, arranged to receive a signal, wherein the control circuit determines whether an analog input pixel of the at least one pixel is a dark pixel according to a magnitude of the analog signal and a time period of an assertion of the signal; and a comparator, arranged to compare the analog input pixel with a first ramp signal having a first swing for m times when the analog input pixel is determined to be the dark pixel; and compare the analog input pixel with a second ramp signal having a second swing for n times when the analog input pixel is not determined to be the dark pixel; wherein the first swing is smaller than the second swing, and tri being greater than n; and a counter, used to count a cycle number of a reference clock until a magnitude of the first ramp signal or a magnitude of the second ramp signal reaches the magnitude of the analog signal for m or n times respectively.
