1. A method for aspirating a specimen accommodated in a cap-sealed container by using a pipette having a sharp edge, comprising steps of: arranging a cap-sealed container accommodating a specimen at a predetermined position;capturing an image of at least a part of the cap-sealed container arranged at the predetermined position;extracting characteristics of a cap of the cap-sealed container from the captured image;determining a movement distance among a plurality of movement distances each customized for respective types of cap-sealed containers, on the basis of the extracted characteristics and a predetermined correspondence relationship of a plurality of characteristics of caps, types of cap-sealed containers and movement distances, the movement distance defined by a distance between an initial position of the pipette and an aspirating position of the pipette;moving the pipette from the initial position to the aspirating position on the basis of the determined movement distance, thereby piercing a cap of the cap-sealed container with the sharp edge and positioning a tip end of the pipette at the aspirating position within the cap-sealed container; andaspirating the specimen in the cap-sealed container via the pipette. 2. The method of claim 1, wherein the cap-sealed container is a blood collection tube and the specimen is a blood. 3. The method of claim 1, wherein the cap-sealed container has a specimen identification data, the method further comprising steps of:obtaining the specimen identification data from the cap-sealed container; andobtaining a measurement order of the specimen accommodated in the cap-sealed container before aspirating the specimen. 4. The method of claim 1, wherein the aspirating position corresponding to the determined movement distance is present in the cap-sealed container without bringing into contact with an inner bottom of the cap-sealed container and the pipette. 5. The method of claim 1, wherein the aspirating position corresponding to the determined movement distance is present near an inner bottom of the cap-sealed container without bringing into contact with the inner bottom and the pipette. 6. The method of claim 1, wherein the characteristics includes a feature value from the captured image of the cap-sealed container and the determination of the movement distance is performed by: determining the movement distance on the basis of the obtained feature value and a predetermined correspondence relationship of feature values, the types of cap-sealed containers and the movement distances. 7. The method of claim 6, wherein the captured image includes color information for each pixel, and the feature value includes color information of a cap of the captured image. 8. The method of claim 6, wherein the feature value includes a value relevant to a shape of a cap of the captured image. 9. The method of claim 6, wherein the determination of the movement distance is performed by: determining a type of the cap-sealed container corresponding to the feature value with reference to a first relationship of feature values and the types of cap-sealed containers; anddetermining the movement distance corresponding to the determined type of the cap-sealed container with reference to a second relationship of the types of cap-sealed containers and the movement distances. 10. The method of claim 1, wherein the cap-sealed container is held by a rack for holding in a row a plurality of cap-sealed containers, the cap-sealed container is arranged at the predetermined position by carrying the rack, andthe image of a cap of the cap-sealed container held by the rack is captured. 11. The method of claim 1, further comprising transporting the cap-sealed container from the predetermined position to a different position at which the aspiration is performed, after capturing the image. 12. A method for automatically aspirating a specimen accommodated in a cap-sealed container by using a pipette having a sharp edge, comprising steps of: transporting a rack holding the cap-sealed container and thereby arranging a cap-sealed container accommodating a specimen at a predetermined position by using a transporting device;capturing an image of at least a part of the cap-sealed container arranged at the predetermined position by using an imaging device;extracting characteristics of a cap of the cap-sealed container from the captured image;determining a movement distance among a plurality of movement distances each customized for respective types of cap-sealed containers by using a control device, on the basis of the extracted characteristics and a predetermined correspondence relationship of a plurality of characteristics of caps, types of cap-sealed containers and movement distances, the movement distance defined by a distance between an initial position of the pipette and an aspirating position of the pipette;moving the pipette from the initial position to the aspirating position on the basis of the determined movement distance by using a pipette moving mechanism of an aspirating device, thereby piercing a cap of the cap-sealed container with the sharp edge and positioning a tip end of the pipette at the aspirating position within the cap-sealed container; andaspirating the specimen in the cap-sealed container via the pipette by using the aspirating device. 13. The method of claim 12, wherein the cap-sealed container has a specimen identification data, the method further comprising steps of:obtaining a specimen identification data from the cap-sealed container by using an identification data obtaining device; andobtaining a measurement order of the specimen accommodated in the cap-sealed container before aspirating the specimen by using the control device. 14. The method of claim 12, wherein the aspirating position corresponding to the determined movement distance is present in the cap-sealed container without bringing into contact with an inner bottom of the cap-sealed container and the pipette. 15. The method of claim 12, wherein the aspirating position corresponding to the determined movement distance is present near an inner bottom of the cap-sealed container without bringing into contact with the inner bottom and the pipette. 16. The method of claim 12, wherein the characteristics includes a feature value from the captured image of the cap-sealed container and the determination of the movement distance is performed by: determining the movement distance on the basis of the obtained feature value and a predetermined correspondence relationship of feature values, the types of cap-sealed containers and the movement distances. 17. A method for determining a movement distance for aspiration of a specimen accommodated in a cap-sealed container, comprising steps of: arranging one of cap-sealed containers held by a rack at a predetermined position, wherein the cap-sealed containers are held by the rack in a row;capturing an image of at least a cap of the cap-sealed container arranged at the predetermined position;extracting characteristics of the cap of the cap-sealed container from the captured image; anddetermining a movement distance among a plurality of movement distances each customized for respective types of cap-sealed containers, on the basis of the extracted characteristics and a predetermined correspondence relationship of a plurality of characteristics of caps, types of cap-sealed containers and movement distances,wherein the aspiration of a specimen accommodated in the cap-sealed container is performed by piercing the cap using a pipette having a sharp edge based on the determined movement distance. 18.
