Therefore, the brightness perception phenomenon and brightness perception theory generated from the printed matters should be revised and modified when applied to the projected images. The purposes of the present research were to examine the effects of brightness illusions while viewing the projected images, to understand the brightness perception process in projection environment, and thus to generate design implications for better usage of the projectors. Keywords: Brightness illusion, Brightness perception, Projector 摘要 本研究提出印刷物與投影影像的觀看條件不同之三大最主要的理由，因此，過去研究 由印刷物所建立的亮度知覺理論及所了解的亮度知覺現象應加以修正調整才能適用於投影 影像。本研究檢驗觀看投影影像時的亮度錯覺現象，藉以了解投影環境中的亮度知覺歷程， 以便對投影機的較佳使用設定與投影影像的較佳設計方式提出具體合宜的建議。 關鍵詞 : 亮度錯覺，亮度知覺，投影機 1. Introduction One of the well-known brightness illusions is the simultaneous contrast effect. As shown in Fig. 1, the two central medium-gray squares are the same shade of gray, but look different because they are against different backgrounds. A square on a dark background looks brighter, and one on a light background looks darker. Previous researchers have proposed some explanations for this effect such as the lateral inhibition in the retina [4, 7], cognitive approaches [2, 6, 10], Gestalt approaches [3, 5, 8, 9], etc. Along with the remarkable progress and application of display projecting industry during recent years, more basic and applied research related to projecting efficiency and brightness perception are needed. However, most of the past studies regarding brightness perception are based on the research results from printed matters and cannot generalize to projected images....
