摘要：An auto-focus projection system includes a light valve, a projecting lens, acamera module, a processing circuitry, and a focusing adjustment assembly. The lightvalve converts an illumination beam into an image beam, and the projection lens projects
the image beam. The projection lens forms different images with respective sharpnessvalues at different focusing positions The camera module captures the different imagesand converting the different images into electrical signals. The processing circuitryreceives the electrical signals and compares the sharpness values to generate a controlsignal. The focus adjustment assembly receives the control signal and moves theprojection lens according to the control signal.
