Claim Text:
1. A method for operating a depth sensing camera, comprising: projecting a light pattern at a first light intensity level into a first environment using an illumination source of the depth sensing camera; capturing a first image of the first environment over a first sensor integration time using an image sensor of the depth sensing camera, the first image is associated with reflected light from the projection of the light pattern at the first light intensity level; determining a degree of pixel saturation associated with the first image using one or more processors; determining a capturing distance from the image sensor; setting a second light intensity level different from the first light intensity level based on at least one of the degree of pixel saturation or the capturing distance from the image sensor; projecting the light pattern at the second light intensity level into the first environment using the illumination source of the depth sensing camera; capturing a second image of the first environment using the image sensor of the depth sensing camera, the second image is associated with reflected light from the projection of the light pattern at the second light intensity level; synthesizing the first image and the second image into a combined image using the one or more processors; determining a third light intensity level different from the second light intensity level based on a degree of pixel saturation associated with the second image; projecting the light pattern at the third light intensity level into the first environment using the illumination source; capturing a third image of the first environment over a third sensor integration time using the image sensor, the third image is associated with reflected light from the projection of the light pattern at the third light intensity level, the capturing the third image is performed subsequent to the capturing the second image, the capturing the second image is performed subsequent to the capturing the first image, the synthesizing the first image and the second image into the combined image includes synthesizing the third image into the combined image, the second light intensity level is less than the first light intensity level, the third light intensity level is greater than the second light intensity level; and generating a depth map based on the combined image.
