Abstract: A structured light projector and a method for structured light projection are disclosed. The structured light projector includes a projection module, an image sensor and a processor. The projection module is configured to project an optical pattern onto a region of space. The image sensor is configured to capture an image by detecting the optical pattern projected onto the region of space. The processor is configured to calculate disparity information of the optical pattern projected onto the region of space from the captured image, and is configured to compensate for the disparity of depending on an environment temperature of the projection module.

Abstract: A structured light projector and a method for structured light projection are disclosed. The structured light projector includes a projection module, a liquid crystal (LC) lens and a processor. The projection module is configured to project an optical pattern. The (LC) lens module is disposed over the projection module, and is configured to focus the optical pattern onto a region of space. The processor is configured to generate a control signal depending on an environment temperature of the projection module for controlling the LC lens.

Abstract: A local dimming system adaptable to a backlight of a display includes a light shape imitation (LSI) unit that receives a pulse-width modulation (PWM) value and provides a profile data for each block of the backlight; a profile analysis unit that generates an analytic mean value according to the profile data; and a diffusion compensation unit that compares the analytic mean value with a target mean value and compensates the PWM value for light diffusion according to a result of the comparison, thereby generating a compensated PWM value.
