Title: Method for correcting quantity of light of optical printer head
Inventor: YAMANAKA SHOSAKU
IPC: B41J2/455
Filed: 1999-11-17
Abstract: PROBLEM TO BE SOLVED: To provide a method for correcting the quantity of light of an optical printer head which can correctly express a gray level even when the gray level of photographic images or the like is required. SOLUTION: According to the method, an optical printer head having a lens array 4 arranged on many light-emitting elements 2 is used and the quantity of light is corrected by adjusting the size of power to be impressed to each of the light-emitting elements 2. At least, two light-emitting elements 2 are let to emit light simultaneously and the intensity of light passing the lens array 4 is measured at an image form position. An MTF value is obtained from a peak value IMAX corresponding to each light-emitting element 2 and bottom values IMIN (>0) proximate to both sides of the peak value or to one side of the peak value in an intensity distribution obtained by the measurement. The size of power to be impressed to each light-emitting element 2 is adjusted in accordance with a difference of the MTF value and an average value of all MTF values.
