Digital Image Capture Under Conditions Of Varying Light Intensity

摘要

An approach is provided to adjust a camera shutter lag. In the approach, data is collected that corresponds to an ambient light found in a physical environment with the ambient light being controlled using a pulse-width modulation (PWM). The pulse-width modulation corresponds to a PWM timing model. When an exposure request is received, the camera shutter lag is calculated using the PWM timing model. The calculated shutter lag is based on a future point in time at which the ambient light of the physical environment is predicted to be at a selected light output level, such as a power level selected by the user of a camera. When the calculated camera shutter lag has expired, a shutter of the camera is opened causing a camera lens to be exposed that results in a captured exposure.

主权项

1. A method implemented by an information handling system to adjust a camera shutter lag, the method comprising:
identifying a pulse rate of an ambient light source; receiving an exposure request; in response to receiving the exposure request:
calculating a camera shutter lag based on a future point in time at which the ambient light source is predicted to be at a selected light output level; andopening a shutter of the camera after the calculated camera shutter lag has expired, the opening causing an exposure of a sensor that results in a captured exposure.
