Patent ID: 8466975

Claim:
An image pickup device, comprising: a sensor array including a plurality of pixels; and an actuator operatively connected to the sensor array; wherein the actuator is configured to sequentially move the sensor array, in a horizontal or vertical direction by one pixel pitch, in response to a control signal, wherein the image pickup device is configured to sequentially detect color component signals of each of the plurality of pixels before a settling time of the sensor array, wherein the sensor array includes first to fourth pixels, wherein the actuator and the image pickup device are further configured to alternately move the sensor array and detect the color component signals, so that: the image pickup device detects a first color component signal of the first pixel from light incident on a particular position; the sensor array moves by the one pixel pitch using the actuator to dispose the second pixel at the particular position; the image pickup device detects a second color component signal of the second pixel from the incident light; the sensor array moves by the one pixel pitch using the actuator to dispose the third pixel at the particular position; the image pickup device detects a third color component signal of the third pixel from the incident light; the sensor array moves by the one pixel pitch using the actuator to dispose the fourth pixel at the particular position; and the image pickup device detects a fourth color component signal of the fourth pixel from the incident light; wherein the image pickup device is further configured to first sum the second color component signal and the fourth color component signal, and wherein the image pickup device is further configured to second sum a signal according to a result of the first summing, the first color component signal, and the third color component signal.
