Abstract

We propose a CIECAM02-based tone mapping technique for color image contrast enhancement that works especially well in bright surrounding conditions. The CIECAM02 is inherently strong when considering human visual systems (HVS) and surrounding conditions. In general, dark regions look darker in bright surrounding conditions, so some details in these dark regions tend to disappear. To overcome this problem, we propose a global tone mapping technique for color image contrast enhancement that uses a gamma encoding and the I/O relationship of the CIECAM02 in bright surrounding conditions. The proposed method makes the contrast of the source image stronger in bright surrounding conditions. We confirmed the superior performance of the proposed method in bright surrounding conditions by psychophysical experiment.
