Abstract
An apparatus is described that includes an image sensor and a light source driver circuit having configuration register space to receive information pertaining to a command to simulate a distance between a light source and an object that is different than an actual distance between the light source and the object.
Claims21
(canceled)
A method, comprising:
- receiving configuration information to simulate a distance between a light source and an object that is different than an actual distance between the light source and the object;
- generating, with a light source driver, a light source drive signal;
- and
- sensing, with depth capture pixels, light that was generated with the light source drive signal and reflected from the object,
- wherein an amplitude of signals sensed with said depth capture pixels is adjusted based on the configuration information to realize the simulated distance.
2 more elements
A system comprising:
- one or more computers and one or more storage devices storing instructions that are operable, when executed by the one or more computers, to cause the one or more computers to perform operations comprising:
- receiving configuration information to simulate a distance between a light source and an object that is different than an actual distance between the light source and the object;
- generating, with a light source driver, a light source drive signal;
- and
- sensing, with depth capture pixels, light that was generated with the light source drive signal and reflected from the object,
- wherein an amplitude of signals sensed with said depth capture pixels is adjusted based on the configuration information to realize the simulated distance.
3 more elements
A non-transitory computer-readable medium storing software comprising instructions executable by one or more computers which, upon such execution, cause the one or more computers to perform operations comprising:
- receiving configuration information to simulate a distance between a light source and an object that is different than an actual distance between the light source and the object;
- generating, with a light source driver, a light source drive signal;
- and
- sensing, with depth capture pixels, light that was generated with the light source drive signal and reflected from the object,
- wherein an amplitude of signals sensed with said depth capture pixels is adjusted based on the configuration information to realize the simulated distance.
