影像調整方法以及影像調整系統

科技關鍵設施研發-先進陸空載具關鍵技術與系統整合計畫

本發明提出一種影像調整方法以及影像調整系統。影像調整方法包括以下步驟：藉由影像感測器取得第一影像信號；藉由低通濾波器對第一影像信號進行濾波，以產生低頻影像信號，並且將第一影像信號減掉低頻影像信號，以產生高頻影像信號；根據低頻影像信號產生最小值，並且根據最小值計算調整值；以及將調整值與高頻影像信號相乘，並且加上參考信號，以取得調整後的影像信號。

The present invention provides an image adjustment method and an image adjustment system. The image adjustment method includes the following steps: acquiring a first image signal via an image sensor; filtering the first image signal using a low-pass filter to generate a low-frequency image signal, and subtracting the low-frequency image signal from the first image signal to generate a high-frequency image signal; generating a minimum value based on the low-frequency image signal and calculating an adjustment value based on the minimum value; and multiplying the adjustment value with the high-frequency image signal, then adding a reference signal to obtain an adjusted image signal.
