不均匀检查方法、显示面板的制造方法以及不均匀检查装置
摘要：
本发明提供一种能够得到与检查员的官能检查结果相近的结果的不均匀检查方法、使用该不均匀检查方法的显示面板的制造方法、以及不均匀检查装置。在检查面板材料中有无不均匀的不均匀检查方法中，按照多个水平的条件拍摄作为检查对象的面板材料(步骤S1)，从该拍摄结果中取得多张一次图像(步骤S2)，对这些一次图像实施强调图像变化的处理，生成多张二次图像(步骤S3)，按照规定的加权合成这些二次图像，生成合成图像(步骤S4)，根据该合成图像来判定有无不均匀(步骤S5)。而且，将规定的加权决定成，使得在针对产生不均匀的示范用的面板材料生成二次图像、合成这些二次图像而生成了合成图像时，可以区分产生不均匀的区域及其以外的区域。
摘要（英）：

An unevenness inspection method for inspecting presence of unevenness in a panel material, the method includes: acquiring a plurality of primary images by imaging the panel material under inspection on a plurality of levels of condition; creating a plurality of secondary images by processing the plurality of primary images to enhance variation of the image; creating a composite image by combiningthe plurality of secondary images with a prescribed weighting; and determining the presence of unevenness using the composite image, the prescribed weighting being determined so that a region having the unevenness can be distinguished from the other region, when the plurality of secondary images are created for the panel material for training use having unevenness and are combined into a composite image.
