摘要： Optical characteristics of an optical component for a high volume manufacture consumer electronics device can be tested using a test chart composed of a superposition of two or more groups of parallel line pairs, wherein all the groups of parallel line pairs are oriented at a different inclination. The groups of line pairs could be oriented so that they are perpendicular to each other. A test system can quickly and objectively assess for example the sharpness of the optical component in different directions across a full image field of view of an imaging system that is capturing a digital image of the chart using the optical component for through-the-lens imaging. Other embodiments are also described and claimed.

摘要： A digital image captured by a digital camera module is scaled to a smaller size, and separately horizontal direction filtered and vertical direction filtered using one-dimensional spatial filters. The horizontal direction filtered image and the vertical direction filtered image are combined, wherein edge regions and corner regions of the combined filtered image are created differently than its middle region. The combined filtered image is then thresholded selected pixels of the thresholded image are marked as a blemish region. Other embodiments are also described and claimed.
摘要翻译：由数码相机模块捕获的数字图像被缩放到较小的尺寸，并且使用一维空间滤波器分离水平方向滤波和垂直方向滤波。组合水平方向滤波图像和垂直方向滤波图像，其中组合滤波图像的边缘区域和角落区域的创建方式与其中间区域不同。然后组合的滤波图像被阈值化，阈值图像的选定像素被标记为瑕疵区域。还描述和要求保护其他实施例。
