Abstract
An approach is provided to adjust illumination color temperature at a flash unit of a camera. Data that corresponds to the ambient light of a physical environment is collected, such as at a color temperature meter included in the camera. The ambient light has a distribution of color temperatures that cycle over a fixed time period. When a flash request is received, a time is calculated at which the flash unit will flash. One of the color temperatures is identified from the distribution of color temperatures with the identified color temperature being the predicted color of the ambient light that will be present in the physical environment when the flash unit flashes. The color temperature of the flash unit is set to the identified color temperature.
Claims9
A method implemented by an information handling system to adjust illumination color temperature, the method comprising:
- collecting data corresponding to ambient light of a physical environment, wherein the ambient light has a distribution of color temperatures that cycle over a fixed time period, and wherein the collected data corresponds to the cycle of color temperatures;
- receiving a flash request;
- calculating a time at which a flash unit will flash in response to the received flash request;
- identifying one of the color temperatures from the distribution of color temperatures, wherein the identified color temperature is a prediction of the color temperature of the ambient light that will be present in the physical environment when the flashing of the flash unit occurs;
- setting a color temperature of the flash unit to the identified color temperature;
- and
- flashing the flash unit after setting the color temperature.
