cosplay 能迷成這樣子，真是超強的啦！

瑋瑋相簿 - 洗澡的好朋友

這六個新朋友是德德堂姐送給瑋瑋的呦！
瑋瑋愈來愈喜歡洗澡了！現在洗澡得快點把他身體洗乾淨，然後多留點時間給他上體育課。而且這堂"起腳動手"的體育課再加入這六個新朋友後，瑋瑋玩起來可是更有活力，讓媽媽都快抓不住了呢！

瑋瑋相簿 - 瑋瑋與蜜餞

躲在蜜餞堆裡會是什麼樣的感覺呢？

別問我，因為小時候我並沒有躲在蜜餞堆裡的經驗！等瑋瑋長大，會說話時，再告訴大家！

瑋瑋相簿 - 瑋瑋與糖果

瑋瑋第一次回澎湖找奶奶跟爺爺！離開台北單調的小客廳、小房間，瑋瑋每次被抱下去店面，來到這一大遍一眼看不完的餅乾、糖果區，總是好奇的東張西望的！
如同爸爸我小時候一般，總不免在眾餅乾、糖果區裡照上幾張照片！這種能躺在餅乾、糖果海裡的體驗，可都是每個小朋友從小的超大願望呢！

瑋瑋相簿 - 媽咪與瑋瑋

瑋瑋洗完澡後，享受完媽咪的5星級按摩。然後，媽咪會讓瑋瑋練習翻身或是趴著！現在瑋瑋可以撐上2~3分鐘的時間呦！^^

瑋瑋相簿 - 瑋瑋愛看書

瑋瑋會看書嘍！雖然，他還看不懂！不過，當他興趣來時，會跟我們一起看上一段時間，雖然持續的時間不長～ 甚至他high起來時，還會去抓書或是摸紙！(當然我知道那些動作應該都是無意識下的動作！)

雖然是無意識下的動作，不過他會看書這件事，可讓身為父母的我跟媽媽開心好一陣了！瑋瑋很棒的呢！

Purpose of IR Filter in Color Cameras

An IR filter – or IR cut filter - is a color filter blocking the infrared light. There are several good reasons for using an IR-cut filter. Using a color camera to achieve realistic colors in white light requires an IR-cut filter. The color spectrum seen by the human eye is quite limited compared to the spectrum seen by a CCD camera. Especially, in the near infrared region of the spectrum the difference in sensitivity is significant. This is important to know since many light sources, including the sun, emit infrared light. A CCD color camera in daylight without an IR-cut filter will therefore see a significant amount of infrared light resulting in strange colors. Another reason for using an IR-cut filter is the limited color correction for many lenses. It is difficult to design imaging optics covering both the visible spectrum and the near infrared spectrum at the same time. Therefore, many lenses have different depth of focus for the visible and the infrared spectrum. Anyway, the IR-cut filter cuts away a significant amount of the overall collected light and thereby affects the sensitivity in a negative way. In general, color cameras are one factor less sensitive compared to monochrome (depending on the CCD chip). This is primarily due to the IR-cut filter.

Infrared (IR) cut-off filters are used with color CCD or CMOS imagers to produce color images. An IR cut-off filter blocks the transmission of the infrared while passing the visible. This can be done with two optical techniques: absorption or reflection. Absorptive filters are made with special optical glass that absorbs near infrared radiation. Reflection type filters are short-pass interference filters that reflect infrared light with high efficiency.

其常見材質約有下列幾項：
1．遠紫外光學石英玻璃
它是用高純度氫氧熔化的光學石英玻璃。具有優良的 透紫外性能，特別是在短波紫外區，其透過性能遠遠地勝過所有其他玻璃，在185mμ處的透過率可達90％，是185─2500mμ波段范圍內的優良光學材料。

2．紫外光學石英玻璃
它是用氫氧熔化的光學石英玻璃。它是透過220─2500mμ波段范圍內的良好材料。

3．紅外石英玻璃
它是具有較高的透紅外性能，透過率高達85％以上，其應用波段范圍260─3500mμ的光學材料。
