摘要： An imaging system with a light source controls the sensitivity of pixels to light, by performing both superpixel modulation and curtain modulation. The superpixel modulation may facilitate rapid data acquisition. The curtain modulation may suppress the effect of ambient light. In superpixel modulation, each pixel set may be modulated by a separate superpixel modulation signal that causes sensitivity of the pixel set to light to vary over time, and each superpixel may include a pixel from each pixel set. The curtain modulation may cause pixels in only a small region of the photodetector to be sensitive to light. The curtain modulation may cause the small region to move to track the dot of light, by changing which pixels are in the region. This invention may be used for 3D scanning.

摘要： In illustrative implementations, a set of separate modulation signals simultaneously modulates a plurality of pixels in a superpixel by a set of separate modulation signals, such that each pixel in the superpixel is modulated by a modulation signal that causes sensitivity of the pixel to vary over time. Each superpixel comprises multiple pixels. In some implementations, the sensitivity of a pixel to incident light is controlled by storage modulation or by light modulation. In some implementations, this invention is used for 3D scanning, i.e., for detection of the 3D position of points in a scene.
