发明名称 Defect and maintenance detection for image capture device
摘要 Defect and maintenance detection for an image capture device (ICD) capable of distinguishing between a defect in the ICD and one on the imaged object. The defect detection system includes, inter alia: a value combiner that combines a brightest image video value for each sensing element of the ICD experiencing the imaged object with a corresponding stored device video value to create a combined value for each image video value; and a defect determinator determines the presence of a defect(s) by comparing the combined values to a defect threshold. The maintenance detection system includes a determinator that determines when maintenance is required based on whether a single image is considered defective or whether a number of consecutive defective images have been created. Device video values are updated sluggishly according to corresponding image video values.
