CMOS图像传感器芯片的自动白平衡算法
Auto White Balance Algorithm for CMOS Image Sensor Chip
摘要
Abstract
A method of gain calculation for auto white balance is proposed which is suitable for hardware implement in CMOS image sensors chip.Based on the method, an auto white balance algorithm used in CMOS image sensors chip is completed.Iterative method and calculation method are combined in this algorithm, and comparator and shift registers are used instead of complex combination logic cells.The computation accuracy and processing speed are improved without hardware expenses.关键词
