Patent number: 6100913Abstract: A method is used for correcting amounts of light of light emitting elements. A first correction range is defined which has a median of maximum and minimum values of the amounts of light of the light emitting elements, and includes a predetermined number of first subdivided ranges. If the minimum amount of light is not within the first correction range, a second correction reference is produced which is smaller than the first correction reference by a predetermined fraction of the difference between the maximum and minimum values. Then, a second correction range is defined which includes the minimum amount of light, has the second correction reference in its middle, and includes a predetermined number of second subdivided ranges.Type: GrantFiled: May 7, 1997Date of Patent: August 8, 2000Assignee: Oki Data CorporationInventors: Yoshihisa Aikoh, Minoru Teshima

Patent number: 5990920Abstract: A driving apparatus has driving circuits that supply driving energy to driven elements which form dots. The driving circuits are controlled by driving data indicating which driven elements are to be driven, and compensation data adjusting the amount of driving energy. The compensation data are stored in compensation memory circuits coupled to the driving circuits. A single data transfer means transfers the driving data to the driving circuits and the compensation data to the compensation memory circuits. If the driven elements are located on two or more different semiconductor chips, some of the compensation data preferably compensate for chip-to-chip differences, while other compensation data compensate for dot-to-dot differences within the same chip.Type: GrantFiled: August 8, 1996Date of Patent: November 23, 1999Assignee: Oki Data CorporationInventors: Akira Nagumo, Minoru Teshima, Jiro Tanuma
