Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A circuit comprising:
a comparator configured to:
generate a first conversion gain output signal by comparing a first pixel signal corresponding to a first conversion gain with a first ramp signal; and
generate a second conversion gain output signal by comparing a second pixel signal corresponding to a second conversion gain with a second ramp signal; and

a counter configured to:
count pulses of the first conversion gain output signal,
output a counting result as a first digital signal, and
determine whether an output of a second digital signal corresponding to the second conversion gain is required, based on the first digital signal,

wherein the first conversion gain is higher than the second conversion gain, and
wherein, based on determining that the output of the second digital signal is not required, the counter is further configured to control the comparator such that the second conversion gain output signal is not generated.
