Abstract

Methods and apparatus, including computer program products, for high dynamic range (HDR) imaging. First image data is captured using a first image sensor and a first exposure time, using a rolling shutter such that different lines within the first image data are captured at different first capture times. Two or more instances of second image data are captured using one or more second image sensors and one or more second exposure times that are shorter than the first exposure time. The two or more instances of second image data are captured using a rolling shutter, and overlap at least in part with the first image data. A line of the first image data has a corresponding line in each instance of second image data, and the corresponding lines in the different instances of second image data are captured at different second capture times. For a line in the first image data, the corresponding line from the instance of second image data whose second capture time is closest to the first capture time, is selected to be merged with the line in the first image data to generate a high dynamic range image.
