Abstract
A method and device for capturing a mixed structured-light image and regular image using an integrated image sensor are disclosed, where the structured-light image is captured using a shorter frame period than the regular image. In order to achieve a shorter frame period for the structured-light image, the structured-light image may correspond to an image captured with reduced dynamic range, reduced spatial resolution, or a combination of them. The capturing process comprises applying reset signals to a pixel array to reset rows of pixels of the pixel array, reading-out analog signals from the rows of pixels of the pixel array and converting the analog signals from the rows of pixels of the pixel array into digital outputs for the image using one or more analog-to-digital converters.
