Claim:
1. A method for measurement of a depth value, comprising: capturing an image of an object illuminated by one or more light patterns effected by multiple pixel-layers, wherein each pixel-layer includes an array of pixels; determining a direction of incoming illumination for a specular reflection at a point on the surface of the object; and determining the depth value of the point on the surface of the object based on the captured image and the direction of incoming illumination, wherein the one or more light patterns result from one or more coded patterns transmitted to the pixel-layers, and wherein each of the one or more coded patterns is a bitplane of a binary code, and wherein the location of a pixel in each of the multiple pixel-layers that is associated with the specular reflection is determined by matching a binarized value of the captured image to a binary code bit value.
