Abstract:
1. A method for calculating a weight ratio by quality grade using a grain appearance quality grade discrimination device for imaging grains using an imager and discriminating the quality grade of the grains on the basis of data of the imaged grains; the method for calculating a weight ratio by quality grades using a grain appearance quality grade discrimination device characterized in comprising: imaging a plurality of grains; discriminating the quality grades of said grains on the basis of data of the imaged grains; tallying, by quality grade, the number of pixels in said data of the imaged grains with regards to the grains whose quality grade has been discriminated; multiplying the number of pixels tallied by quality grade by a weight conversion coefficient per pixel predetermined by quality grades, by location of production, by variety, and thereby converting said number of pixels into a weight by quality grade; and calculating the weight ratio by quality grade of the grains on the basis of the weight by quality grade.
