嵌入式画质实时评价系统设计

摘要

This paper presents a method for camera quality evaluation in embedded application, which gets scores of real-time frame according to the selection of experienced image areas with the measurable character of RGB histogram. The method is not focused on the captured images but the real-time frame evaluation during preview, so the inexperienced users could get high quality with tuning of capture angle and menu performance.%提出一种应用于嵌入式终端的画质评价方法,根据预览时图像的经验分区选择,利用RGB直方图的可度量性,评价当前拍摄质量的得分.本方法突出评价的实时性,在预览而非拍摄后即可为用户提供判别标准.借此,不具备专业摄影知识的用户亦可以通过调节设备的菜单功能和拍摄视角获得优秀画质.
