    Abstract: A pixel for an image sensor includes a resistive microbolometer sensor portion, a visible image sensor portion, and an output path. The resistive microbolometer sensor portion outputs a signal corresponding to an infrared (IR) image sensed by the resistive microbolometer sensor portion. The resistive microbolometer sensor portion uses no bias current. The visible image sensor portion outputs a signal corresponding to a visible image sensed by the visible image sensor portion. The output path is shared by the resistive microbolometer sensor portion and the visible image sensor portion, and may be controlled to selectively output the signal corresponding to the IR image, the signal corresponding to the visible image, or a fused image based on the IR image and the visible image. The resistive microbolometer sensor portion may sense a near infrared image or a longwave infrared image.
