Recently, the image quality in display devices have been improving, and widely used under various environment illuminations. However, appearance of display devices is difference in various environment illuminations. Therefore, the robustness of image quality factors in various environment illuminations is examined. The study obtains values of subjective image quality from image quality factors using the already proposed estimation equation, and analyzes the robustness of image quality factors in different environment illumination using the parameter design on the bases of the values of subjective image quality. Image quality factors are gamma, maximum luminance and minimum luminance, and environment illuminations are D65 illumination, darkroom and indirect sunlight. |
