Abstract
An apparatus for forming an image includes a photosensitive body, an optical write unit which scans a light beam along a main scan path on a photosensitive body to create a latent image thereon, the light beam having power levels corresponding to multi-level image data, and a shading correction unit which corrects shading along the main scan path by making adjustment to the multi-level image data along the main scan path, and changes the adjustment on a condition-specific basis.
Claims12
An apparatus for forming an image, comprising:
- a photosensitive body;
- an optical write unit which scans a light beam along a main scan path on a photosensitive body to create a latent image thereon, said light beam having power levels corresponding to multi-level image data;
- and
- a shading correction unit which corrects shading along said main scan path by making adjustment to the multi-level image data along said main scan path, and changes said adjustment on a condition-specific basis.
The apparatus as claimed in claim-1, wherein said optical write unit creates said latent image for different colors, and said shading correction unit changes said adjustment depending on which one of the different colors corresponds to said latent image being created.
Dependencies are inferred from the claim text.
