Abstract: A projector and a projection method are provided. The projector is coupled to a display card and includes a light source, a light valve, a projection lens, and a processor. The light source provides an illumination beam. The light valve converts the illumination beam into an image beam. The projection lens projects the image beam to the outside of the projector to form an imaged image.

The first resolution is less than the second resolution.

Abstract: Enhanced passthrough images are generated and displayed. A current visibility condition of an environment is determined. Based on the current visibility condition, a first camera or a second camera, which detect light spanning different ranges of illuminance, is selected to generate a passthrough image of the environment. The selected camera is then caused to generate the passthrough image. Additionally, a third camera, which is structured to detect long wave infrared radiation, is caused to generate a thermal image of the environment. Parallax correction is performed by aligning coordinates of the thermal image with corresponding coordinates identified within the passthrough image. Subsequently, the parallax-corrected thermal image is overlaid onto the passthrough image to generate a composite passthrough image, which is then displayed.

Measured data out of the DUT is compared with expected data. Based on the result of the comparison, a signal indicates the pass or fail of the self-test concludes a self-test of the DUT.
