Abstract
An image forming apparatus includes a printer unit that prints an image on a sheet using a line head in which a plurality of light emitting devices are arranged, and a storage unit that stores information regarding light amounts corresponding to the light emitting devices of the line head. The image forming apparatus generates a mask pattern based on the information regarding the light amounts obtained from the storage unit and a target light amount, and executes mask processing on halftone image data that is in positional correspondence with the light emitting devices using the generated mask pattern.
Claims11
An image forming apparatus comprising:
- a printer unit that prints an image on a sheet using a line head in which a plurality of light emitting devices are arranged;
- a storage that stores information regarding light amounts corresponding to the light emitting devices of the line head;
- a memory that stores instructions;
- and
- a processor that executes the instructions stored in the memory to:
- generate a mask pattern based on the information regarding the light amounts obtained from the storage and a target light amount, and
- execute mask processing on halftone image data that is in positional correspondence with the light emitting devices using the generated mask pattern.
A method of controlling an image forming apparatus that includes a line head in which a plurality of light emitting devices are arranged and a memory that stores information regarding light amounts corresponding to the light emitting devices of the line head, and forms an image using the line head, the method comprising:
- generating a mask pattern based on the information regarding the light amounts obtained from the memory and a target light amount, and
- executing mask processing on halftone image data that is in positional correspondence with the light emitting devices using the mask pattern generated in the generating.
A non-transitory computer-readable storage medium storing a program for causing a processor to execute a method of controlling an image forming apparatus that includes a line head in which a plurality of light emitting devices are arranged and a memory that stores information regarding light amounts corresponding to the light emitting devices of the line head, and forms an image using the line head, the method comprising:
- generating a mask pattern based on the information regarding the light amounts obtained from the memory and a target light amount, and
- executing mask processing on halftone image data that is in positional correspondence with the light emitting devices using the mask pattern generated in the generating.
