HAD devices function by reducing dark current that occur in the absence of light falling on the imager for noise reduction and enhanced image quality. HAD CCDs are used in consumer and professional single, as well as, three-chip video cameras. ==Operation== The "hole" refers to places in a semiconductor where an electron has been dislodged, thus creating a positive charge. These "holes" or positive charges can be created by heat or imperfections in the creation of the imaging chip. The "holes" are accumulated, or trapped, in a separate semiconductor layer that acts as a diode that prevents them from returning or creating noise. HAD technology suppresses the fixed pattern noise that results from "dark" current that occurs regardless of the amount of absorbed light. By fabricating a hole-accumulation layer below the surface of the CCD, "dark" current can be suppressed at the source. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Hole accumulation diode」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
