Abstract: A method of detecting one or more errors in a series of electronically processed, multi-pixel images, the pixels of which correspond from one image to the next, the method including monitoring the reflectance of one or more of the corresponding pixels during sequential processing of each image of the series and, if the reflectance value of a pixel is invariant or substantially invariant in more than a predetermined number of consecutive said images, and identifying an error.

Abstract: A method of discriminating between kernel and chaff particles, in crop, using a crop viewing apparatus that includes an image-capturing device that is capable of capturing one or more images of crop in the crop viewing apparatus. The image capturing device connected to a processing device for processing one or more resulting images. The crop viewing apparatus also includes one or more lamps for illuminating crop in the crop viewing apparatus. The lamp illuminates the crop in a range of illumination levels up to a maximal level equal to or above a reflectivity saturation level at which increasing illumination causes no further reflectivity change. The crop viewing apparatus further includes one or more control devices for controlling the level of illumination provided by each lamp.
