COUNTER READOUT CIRCUIT AND CONTROL METHOD

原文（中国語）

The present application provides a counter readout circuit and control method, each counter unit is connected to a counter readout circuit. The first selector's first input end is connected to the corresponding counter unit, and the second input end is connected to the data output signal of the lower-level counter readout circuit. The control end of the first selector receives a first selection signal to select the first input end or the second input end. The output end of the first selector is connected to the input end of the first trigger, and the output end of the first trigger outputs the data output signal of the counter readout circuit. The trigger end of the first trigger is coupled to the second input end of the first selector of the higher-level counter readout circuit. The technical solution of this application can effectively reduce the power consumption of the image sensor.
