This paper presents an improved method of image reconstruction from the chopperless pyroelectric infrared image sensors. In the chopperless image sensor using chip shift operation, the output is a spatially differentiated image. The original IR light image can be reconstructed from the sensor output using the spatial integration. The improved method uses the chip shift operations to both x and y direction to cancel the stripe shape noise. This technique much improves the quality of the reconstructed image.
