Publication number: 20070285494Abstract: A light scanning apparatus includes a plurality of light sources. A detection unit detects the light power of a light beam output from at least one of the plurality of light sources. A control unit controls the driving current of at least one selected light source on the basis of the detection result by the detection unit such that the light power of the selected light source equals a target light power. The light source is selected from the plurality of light sources on the basis of the light-emitting characteristic of each light source. The control unit controls, on the basis of the driving current of the selected light source, the driving currents of light sources which remain unselected in the plurality of light sources.Type: ApplicationFiled: June 7, 2007Publication date: December 13, 2007Applicant: CANON KABUSHIKI KAISHAInventor: Tomohiro KAWAMOTO

Publication number: 20070285493Abstract: An optical power control apparatus includes a changing unit which changes, a plurality of number of times, the value of a current flowing to an optical beam output apparatus, and an obtaining unit which obtains, in correspondence with each current value, a peripheral optical power representing an optical power at the peripheral part of the spot of the optical beam output from the optical beam output apparatus. The optical power control apparatus also includes a correction unit which corrects the peripheral optical power so that the peripheral optical power and a central optical power representing an optical power at the central part of the spot have an approximately linear relationship in correspondence with each current value. The optical power control apparatus also includes a control unit which controls the optical power of the optical beam output from the optical beam output apparatus in accordance with the corrected peripheral optical power.Type: ApplicationFiled: June 4, 2007Publication date: December 13, 2007Applicant: CANON KABUSHIKI KAISHAInventors: Tomohiro KAWAMOTO, Shingo KITAMURA
