System, method, and computer program product implementing an image processing pipeline for high-dynamic range images

摘要

A system, method, and computer program product for generating high-dynamic range image data is disclosed. The method includes the steps of receiving image sensor data from an interleaved image sensor. The interleaved the image sensor includes a first portion of pixels exposed for a first exposure time and a second portion of pixels exposed for a second exposure time that is shorter than the first exposure time. The method further includes the steps of identifying a first subset of pixels in the second portion having an intensity value above a first threshold value, identifying a second subset of pixels in the first portion having an intensity value below a second threshold value, and generating high-dynamic range (HDR) data based on the first subset and the second subset.

1. A method comprising:
capturing image sensor data from an interleaved image sensor that includes a first portion of pixels exposed for a first exposure time and a second portion of pixels exposed for a second exposure time that is less than the first exposure time by:
resetting the pixels in the first portion at a first reset time,resetting the pixels in the second portion at a second reset time, andsampling the pixels in the first portion and the second portion after a sampling time has elapsed since the first reset time; receiving the image sensor data from the interleaved image sensor; identifying a first subset of pixels in the second portion having an intensity value above a first threshold value; identifying a second subset of pixels in the first portion having an intensity value below a second threshold value; and generating high-dynamic range (HDR) data based on the first subset and the second subset, wherein the difference between the sampling time and the first reset time is equal to the first exposure time and the difference between the sampling time and the second reset time is equal to the second exposure time.
