In normal circumstances, adjust the common judgement conditions. Set the individual judgement conditions to perform strict or lenient judgement for a particular character. Common Judgement Conditions Use this function to set common judgement conditions for all models. Common judgement OK value (OK if at or above this value) Similarity level : [ 60] Differential level : [ 10] End Similarity level for 1st candidate (0 to 100 (60*)) Difference level between 1st and 2nd candidates (0 to 100 (10*)) 1.

Density images are the gray images of 256 gradations read by the Camera. Flow control is used to adjust the rate of data transfer. The receiving side notifies the sending side when it cannot keep up with the processing speed, causing the sending side to interrupt the transmission, and then the receiving side notifies the sending side when it wants the transmission to be restarted.
