动态范围对手机拍照质量的影响

The influence of dynamic range on the quality of mobile pictures

动态范围是评估手机拍照质量的一项重要指标。根据手机动态测试的方法及ISO 14524标准建议的透射式测试图卡,建立基于光电转换函数(opto-electronic conversion function,OECF)成像测试系统模型,确定其测试要求,同时对不同手机拍照的动态范围进行分析,明确动态范围的差异对手机拍照能力的影响,为研发人员调整手机拍照功能提供参考。

Dynamic range is an important indicator to assess the quality of mobile phone camera imaging.This article starts with the method of mobile phone dynamic test,establishes a model based on the opto-electronic conversion function（OECF）imaging test system according to the ISO 14524 standard recommended transmission test chart model,specifies its test requirements,analyzes the dynamic range of different mobile phone pictures,and determines the difference of dynamic range.The influence of mobile phone camera capability provides data support and reference for research and development personnel to adjust mobile phone camera function.
