Abstract: The present invention provides an imaging apparatus capable of reducing power consumption. The imaging apparatus has pixels and first to seventh circuits. The pixels are arranged in a matrix to configure a pixel array. The first and second circuits select rows and columns of the pixel array. The third circuit calculates the differences of the image data of a first frame and the image data of a second frame of selected pixels. The fourth and fifth circuits output the pixels completed with difference calculations or the row and column addresses of the pixels completed with the difference calculations in advance. The row and column addresses defining designated areas of the pixel array are stored to the sixth circuit. The seventh circuit compares the coordinates included in the stored areas and the coordinates of pixels with detected differences. When the coordinates of the pixels with the detected differences are included in the areas stored to the sixth circuit, the image data of a third frame is obtained and output to an external device which can be a display device or a memory device.
