Systems and methods for generating a high-dynamic range (HDR) pixel stream

摘要

A system, method, and computer program product are provided for performing high dynamic range mixing on a pixel stream. In use, the system receives a pixel stream including at least two exposures per pixel from a plurality of pixels of an image sensor. The system then generates a high dynamic range (HDR) pixel stream by performing HDR mixing on the received pixel stream. Finally, the system outputs the HDR pixel stream. Additional systems, methods, and computer program products are also presented.

1. An apparatus, comprising:
circuitry for:
receiving a pixel stream including at least two exposures per pixel from a plurality of pixels of an image sensor, wherein receiving the pixel stream includes receiving a first exposure of a pixel, a second exposure of the pixel, and a third exposure of the pixel;identifying a first pixel attribute of the first exposure of the pixel;identifying a second pixel attribute of the second exposure of the pixel;identifying a third pixel attribute of the third exposure of the pixel;identifying a first scalar based on the first pixel attribute and the second pixel attribute;identifying a second scalar based on the second pixel attribute and the third pixel attribute;blending, based on the first scalar, the first exposure of the pixel and the second exposure of the pixel;blending, based on the second scalar, the second exposure of the pixel and the third exposure of the pixel;generating a first resulting pixel based on the blending of the first exposure of the pixel and the second exposure of the pixel; andgenerating a second resulting pixel based on the blending of the second exposure of the pixel and the third exposure of the pixel;generating a high dynamic range (HDR) pixel stream by performing HDR mixing on the first resulting pixel and the second resulting pixel; andoutputting the HDR pixel stream.
