The pixel size of p + / n - well / p - sub structure is 100 umx 100 n m, fill factor is 77. 6 %. it can obtain target information with illuminance intensity in the range of 0. 011x ~ 98, 0001x, and the sensor photoelectric sensitivity is 35v / lx ? s. when the method of changeable reset frequency double scanning is used, the photoelectric dynamic range can be 139. 8db, which is high in the 0. 6 um level cmos image sensors already reported
在對感光單元進行器件物理結構優化的研究中，通過採用深結深光電管結構，提高了傳感器的感光響應，其中p m階」襯底結構的傳感器面積為100umx100urn ，感光面積百分比為77石，可對0刀98 ， 000lx照度的目標信號進行傳感，感光靈敏度大於3sv ix ? s ，採用了變頻兩次掃描后，動態范圍可達139 -
Secondly, image enhancement technique based on linear filtering is adopted. a new image segmentation method by means of automatic multilevel threshold is given, which realizes partial multilevel threshold segmentation based on image region partition of gray - level position projection, removes the influence of uneven illuminance or uneven gray - level distribution on goal recognition, and resolves the problem of error segmentation caused by threshold step between adjacent regions by threshold transition. the method has well robustness
在圖像處理時，採用基於線性濾波的圖像增強方法，並提出了一種新的自動多閾值圖像分割方法，該方法以基於灰度位置投影的圖像分區實現局部多閾值分割，克服了不均勻照明或不均勻灰度分佈對目標識別的影響，同時，通過閾值過渡很好地解決了相鄰區域閾值「階躍」引起的錯誤分割問題，具有很好的魯棒性。 -
