Title: Image forming apparatus
Inventor: MIZOGUCHI YOSHIHITO
IPC: G03G5/05
Filed: 1997-12-26
Abstract: PROBLEM TO BE SOLVED: To form a highly accurate electrostatic latent image by regulating an exposing means such that the shaft of interval of a plurality of light beams from a prescribed value and the shift of the quantity of light of each light beam from a mean quantity of light determined by dividing total quantity of light by the number of light beams fall within a range satisfying a specific equation. SOLUTION: An image exposing unit 3 comprises two semiconductor lasers 11a, 11b emitting laser light beam, a collimator lens 12, and a laser track circuit 15. When the difference of output between two lasers 11a, 11b is varied and the scanning line interval of laser is combined with the quantity of laser light, the shift x% of line interval and the shift y% of the quantity of laser light can be suppressed to an allowable level as a result of evaluation with eyes if a relationship x+y<10 is satisfied. Consequently, a pattern can be eliminated or can e rendered inconspicuous even for a solid image.

IPC: G02B27/18
Filed: 1999-12-28
Abstract: PROBLEM TO BE SOLVED: To improve an image quality by performing stable white balance adjustment while expanding and projecting a usual video with a simple configuration. SOLUTION: In a projection type display device using a digital micro mirror device 3, light beams reflected in a first direction among light beams reflected from the digital micro mirror device 3 are projected on screen 5 to display an image, and light beams reflected in a second direction is received by a photosensor 6a to measure optical information.
