Abstract
The imaging device includes a pixel array and first to seventh circuits. The first and second circuits select a pixel in the pixel array. The third circuit performs difference calculation between imaging data of the first frame and the second frame in the selected pixels. The fourth and the fifth circuits output addresses of the row and column of the pixels which has been subjected to the difference calculation. A row address and a column address for determining a specific region of the pixel array are stored in the sixth circuit. The seventh circuit compares coordinates included in the specific region with coordinates of pixels where a difference is detected. If the coordinates of the pixels where a difference is detected are included in the specific region which has been stored in the sixth circuit, imaging data is obtained again and is output to the external devices.
