Abstract: In some embodiments, a method of operating an image sensor supporting a low speed mode and a high speed mode includes: outputting a first set of output signals from a first pixel group to a first output line group by enabling, during a first period of the low speed mode, a first load circuit group connected to the first set of output signals; outputting a second set of output signals from a second pixel group to a second output line group by enabling, during a second period of the low speed mode different from the first period, a second load circuit group connected to the second set of output signals; and disabling the second load circuit group during at least a part of the first period.

Abstract: A counter includes a buffer unit and a ripple counter. The buffer unit generates at least one least significant signal of a count by buffering at least one clock signal until a termination time point. The ripple counter generates at least one most significant signal of the count by sequentially toggling in response to at least one of the least significant signal. The counter performs multiple data rate counting with enhanced operation speed and reduced power consumption.
