Claim 0:
1. A method comprising:
determining, by a distance decoder at an earth surface, a first depth value of a downhole component in a borehole, the downhole component comprising a processor;
transmitting, by a surface control unit, from the earth surface and through a downhole telemetry system to the downhole component in the borehole a first signal indicating the first depth value, determined by the distance decoder;
obtaining, during a drilling operation and using the downhole component, a first image at the first depth value;
changing a depth of the downhole component in the borehole;
determining, by the distance decoder at the earth surface, a second depth value of the downhole component in the borehole;
transmitting, by the surface control unit, from the earth surface and through the downhole telemetry system to the downhole component in the borehole, a second signal indicating the second depth value determined by the distance decoder;
obtaining, during the drilling operation and using the downhole component, a second image at the second depth value;
aligning, during the drilling operation and using the processor in the downhole component, the first image and the second image using the indicated first depth value and the indicated second depth value;
performing in downhole, during the drilling operation, by using the processor in the downhole component, image analysis on the aligned first image and the aligned second image; and
updating in the downhole, using the processor in the downhole component, a downhole operation performed by the downhole component based on at least one of the indicated first depth value, the indicated second depth value, and the image analysis of the aligned first image and the aligned second images 
wherein the updating in the downhole of the downhole operation includes transmitting, by the surface control unit, from the earth surface to the downhole component a calibration depth value after changing the depth of the downhole component in the borehole by a predefined depth interval, and calibrating the second depth value using the calibration depth value.
