S3C6410平台上自动聚焦的研究与实现
Research and realizations of auto-focus based on S3C6410
随着数字图像处理技术的迅猛发展自动聚焦技术的实现尤为重要，论文主要是讲述如何在S3C6410平台上实现自动聚焦功能。论文中使用了亮度差分函数作为图像清晰与否的评价标准，此算法具有良好的单调性和无偏性，而且具有稳定性和快速性。最后在此评价函数的基础上，使用改进型的盲人爬山法实现了快速、精确地聚焦。
With the rapid development of digital image-processing technology, this paper mainly presents how to achieve the auto-focus function on S3C6410. The luminance scale difference function was used to indicate whether the system was on accurate focus or not. Because this function not only has the characteristics of single peak value, non-deflection, reliability, high-speed, but also has lower complex computation than the frequency methods such as FFT(Fast Fourier Transform), DWT (Discrete Wavelet Transform). This paper employed the method of new blind hill climbing to achieve auto-focus.
