Patent number: 9628667Abstract: In a scanning apparatus, a controller is configured to obtain black reference data, compensated data based on digital data (scan data) by scanning a reference member with the light source turned off, and the black reference data. The controller further compares the compensated data with a first particular value. The controller executes the compensated data obtaining process with setting the light amount adjustment value to be a smaller value when the compensated data is greater than the first particular value, while with setting the light amount adjustment value to be a greater value when the compensated data is less than the first particular value. Further, the controller sets the light amount adjustment value to be a scan-time light amount adjustment value when the light amount adjustment value is equal to the first particular value. Then, the controller executes a scanning process according to the scan-time light amount adjustment value.Type: GrantFiled: March 28, 2016Date of Patent: April 18, 2017Assignee: BROTHER KOGYO KABUSHIKI KAISHAInventor: Hiroyuki Nakazawa
