Compensation Concept 全视角膜补偿概念
Normal View Normal View Lower view 下视角 Lower view 下视角 Good! ~ -10 to -15% Compensated Signal 补偿影像光 標題 排好, 有必要成兩行.把 of ominiwide film刪掉,,直接留下Compensation concept,看這樣如何? 上面那兩個帶很多字的泡泡, 去掉. 要表達的意思看能不能用圖代表, 見 5.OK 去掉泡泡, 其他的內容整體往上提, 空出下方~ ¼ 的空白做 4. OK 寫上 GSI: Gray Scale Inversion 是不是用個小圖 表示出 正常圖內容 以及 GSI的影像, 就擺在該是角的位置.

OK 格子內的字, 精簡些. 因為還要給Jimmy放入日文. 所以例如OK Top Polarizer 改成 Top Pol. / 上偏光板 Compensation film 改成 Comp.
