Abstract
The present invention provides a readout integrated circuit and an operation method thereof. The readout integrated circuit includes a readout circuit, a line buffer and a communication interface circuit. The readout circuit reads out a plurality of row sensing results of a plurality of sensor rows of a sensor. The line buffer is coupled to the readout circuit for temporarily storing a current row sensing result of a current sensor row of the sensor. The communication interface circuit is coupled to the line buffer. After the current row sensing result of the current sensor row is temporarily stored into the line buffer, the communication interface circuit outputs the current row sensing result in real time to a host circuit.
