Method for performing light shaping with aid of adaptive projector, and associated apparatus

A hybrid depth detection device, comprising:

• an image processing circuit, arranged to obtain distance information, determines a distance range according to the distance information, and perform projection light-shaping type selection to determine at least one selected projection light-shaping type corresponding to the distance range among multiple predetermined projection light-shaping types, wherein the distance information indicates a distance between the hybrid depth detection device and one or more target objects, the distance range is selected from multiple predetermined distance ranges regarding the distance, and the at least one selected projection light-shaping type is selected from the multiple predetermined projection light-shaping types;
• an adaptive projector, coupled to the image processing circuit, arranged to perform projection of the at least one selected projection light-shaping type to perform spatial exposure bracketing, to allow the hybrid depth detection device to capture at least one corresponding image with a camera;
• and
• the camera, coupled to the image processing circuit, arranged to capture the at least one corresponding image;
• wherein:
• the image processing circuit performs at least one detection operation according to the at least one corresponding image to generate at least one detection result, for performing subsequent processing of the hybrid depth detection device, wherein the subsequent processing comprises depth-related detection.
