Abstract

Cell phone camera manufacturers use a variety of illuminant estimation methods to automatically white balance images, which often produce very different results. The goal of this study is to estimate aim white point as a function of the light source used during image capture. The results of this study may support a standard aim point for automatic white balance algorithms. Images with eight different scene light sources and five scene contents were captured and displayed using color correction and color management techniques. A Method of Adjustment experiment was conducted to determine the average preferred white-point and variation in preference between observers for images captured under different light sources and with different scene contents. This research provides information about how the preferred white-point for balancing an image changes dependent on the actual scene light source and the scene content.
