Abstract
The technology described in this document can be embodied in a method for capturing an image. The method includes generating a first control signal configured to cause a rolling shutter camera to capture an image of a subject over a first time period. The method also includes generating, at a first time point during the first time period, a second control signal configured to set a multi-spectral illumination source at a first intensity level. The multi-spectral illumination source is configured to illuminate the subject. The method further includes generating, at a second time point during the first time period, a third control signal configured to set the multi-spectral illumination source at a second intensity level that is less than the first intensity level. A portion of the image captured by the rolling shutter camera between the first and second time points includes a target feature associated with the subject.
