Abstract
Description
本發明係有關於一種鏡頭模組,特別是一種具有遮光結構的鏡頭裝置。 The invention relates to a lens module, in particular to a lens device with a light-shielding structure.
一般相機在使用時,若有角度不佳的強烈光線進入鏡頭會導致拍攝的影像畫質不佳,輕微者會出現光斑,嚴重者則會讓整體影像呈現朦朧不清。對此,目前相機會在鏡頭前方加裝遮光罩,以減少拍攝時因雜光所造成的畫質受損,並可增加影像的色彩及飽和度。 In general, when a camera is in use, if a strong light from a poor angle enters the lens, the image quality of the shot will be poor. The light spots will appear, and the severe ones will make the overall image appear hazy. In this regard, the current camera will install a hood in front of the lens to reduce the image quality damage caused by stray light during shooting and increase the color and saturation of the image.
再者,市售的膚質檢測儀器是利用鏡頭模組近距離地拍攝待檢皮膚,再根據所拍攝出來的皮膚影像進行分析,從而得知待檢皮膚的生理狀況。如圖1所示,目前用於膚質檢測儀器的鏡頭裝置1a主要設置有鏡頭模組10a、發光元件20a及感光元件30a等結構,其運作方式是將聚焦透鏡40a靠近待測皮膚,此時,發光元件20a所發出的光線,例如光線21a,會穿出該聚焦透鏡40a並經過待測皮膚後反射,最後,從該待測皮膚反射的光線會再穿入該聚焦透鏡40a,並透過該鏡頭模組40a而傳入感光元件30a,進而獲得皮膚影像。
Furthermore, commercially available skin quality testing instruments use lens modules to photograph the skin to be tested at close range, and then analyze the captured skin images to learn the physiological condition of the skin to be tested. As shown in Figure 1, the
請參照圖2,其係顯示目前鏡頭裝置1a所獲得的皮膚影像。進一步而言,圖1中鏡頭裝置1a中的發光元件20a所發出部分角度不佳的光線,例如光線22a,會經過反射片50a的反射而直接進入鏡頭模組10a。又,這些角度不佳的光線即是導致拍攝的影像畫質不佳的原因。
Please refer to FIG. 2, which shows the skin image obtained by the
有鑑於此,本發明人遂針對上述現有技術,特潛心研究並配合學理的運用,盡力解決上述之問題點,即成為本發明人改良之目標。 In view of this, the inventor of the present invention focused on the above-mentioned prior art, especially concentrated research and the application of scientific theory, and tried to solve the above-mentioned problems, which became the goal of the present inventor's improvement.
