    Abstract: An optical sorter includes a first light source disposed on a first side, a second light source disposed on a second side, an optical sensor configured to detect light during a plurality of scan periods including a first scan period and a second scan period, a determination part configured to determine a foreign object and/or a defective product, and a light source control part. The light source control part is configured to control the first light source and the second light source during the first scan period so as to turn on the first light source and/or the second light source in a first lighting pattern, which is a lighting pattern arbitrarily selected from a lighting pattern in which the first light source and the second light source are at least partially on, a lighting pattern in which only one of the first light source and the second light source is at least partially on, and a lighting pattern in which only the other of the first light source and the second light source is at least partially on, and is also configured to control the first light source and the second light source during the second scan period so as to turn on the first light source and/or the second light source in a second lighting pattern, which is a lighting pattern selected arbitrarily except for the first lighting pattern.

    Abstract: An object of the present invention is to improve the quality level discrimination accuracy of the grain G by a grain quality level discrimination device. The device includes an optical unit 3 that emits light to the grain G, receives reflected and/or transmitted light from the grain G by a photosensor, and obtains information for discrimination of the quality level of the grain G from the upper and lower surface side of the grain G, and a quality level discrimination unit 7 that discriminates the quality level of the grain G on the basis of the information. The information on the upper and lower surface sides can be acquired by one optical unit at the same time so that the divergence therebetween due to the displacement or variation of the attitude of the grain G can be avoided. The reference plate for the correction of the information is placed outside of the moving path of the grain G to prevent it from soiling or damaging. Thus the deterioration of information can be avoided. Further, a reference plate especially for the information to be obtained from the side surface of the grain G may be provided for enhancing the accuracy of the side surface information. Thus the quality level discrimination accuracy can be improved further.

    Abstract: A technical object is to enable optical checks to be performed while allowing visual checks using a sample pan to be performed in a pseudo manner using an aggregate image (pseudo image) depicting grains loaded on the sample pan, by optically checking the grains using image information on the grains imaged by an imaging apparatus and creating the aggregate image using the image information. Thus, a grain appearance measuring apparatus includes imaging means for imaging a plurality of grains, analysis means for analyzing image information on the grains imaged by the imaging means in units of grains, processing means for processing the image information to form an aggregate image of the grains, and means for saving and/or displaying the aggregate image processed by the processing means. The processing means extracts grain images from the image information in units of grains and arranges the extracted grain images in units of grains, in a close state where the grain images are close to one another to form an aggregate image of the grain images.
