摘要:
The color tone compensation method provides a simple and efficient method to compensate the color tone differences between two different sources of images. A first image sample, such as a still image, from a first image capturing source and a second image sample, such as a video frame, from a second image capturing source are aligned, and a tone-mapping estimation routine is applied to the two aligned images. The tone-mapping estimation routine uses the pixel intensity value histograms associated with the two aligned images and generates a tone mapping table. The tone mapping table includes a conversion intensity value for each intensity value in the second image. The conversion intensity value is a statistical measure, such as the mean, calculated according to the data in the corresponding pixel intensity value histogram. The tone-mapping table is applied to any image generated by the second image capturing source, thereby generating a new image with similar color tone as the first image generated by the first image capturing source.
