Abstract
An apparatus is described that includes an image sensor having a first output port and a second output port. The first output port is to transmit a first image stream concurrently with a second image stream transmitted from the second output port.
Claims14
A computing system, comprising:
- an image sensor comprising a first output port that is associated with a first clock, and a second output port that is associated with a second clock, wherein the first output port transmits a first, RGB image stream at a first rate according to the first clock, concurrently with a second, depth image stream transmitted from the second output port at a different, second rate according to the second clock;
- an applications processor, the applications processor comprising a first image signal processing pipeline and a second image signal processing pipeline, wherein the first image signal processing pipeline processes the first, RGB image stream, wherein the second image signal processing pipeline processes the second, depth image stream, and wherein the applications processor concurrently processes the first, RGB image stream and the second, depth image stream with the first and second image signal processing pipelines without requiring either of the first or second image signal processing pipelines to multiplex between processing the first, RGB image stream and the second, depth image stream.
A method performed by a computing system, comprising:
- transmitting a first, RGB image stream from a first output port of an image sensor at a first rate according to a first clock that is associated with the first output port, while transmitting a second, depth image stream from a second output port of the image sensor at a different, second rate according to a second clock that is associated with the second output port;
- processing the first, RGB image stream with a first image signal processing pipeline on an applications processor while processing the second, depth image stream with a second image signal processing pipeline on the applications processor without requiring either of the first or second image signal processing pipelines to multiplex between processing the first, RGB image stream and the second, depth image stream.
A non-transitory machine readable storage medium having stored thereon program code that when processed by a computing system causes the computing system to perform a method, comprising:
- configuring an image sensor to transmit a first, RGB image stream from a first output port of the image sensor at a first rate according to a first clock that is associated with the first output port;
- configuring the image sensor to transmit a second, depth image stream from a second output port of the image sensor at a different, second rate according to a second clock that is associated with the second output port, concurrently with the transmission of the first, RGB image stream from the first output port;
- configuring a first image signal processing pipeline of an applications processor to process the first, RGB image stream, without requiring the first image signal processing pipeline to multiplex between processing the first, RGB image stream and the second, depth image stream;
- configuring a second image signal processing pipeline of the applications processor to process the second, depth image stream, without requiring the second image signal processing pipeline to multiplex between processing the first, RGB image stream and the second, depth image stream.
