IMAGE FORMING APPARATUS

摘要

An image forming apparatus which inhibits occurrence of defective image caused when buffer consumption amount in the sector correction exceeds a previously estimated capacity. The image forming apparatus comprises a line buffer for temporarily storing image data. The image forming apparatus performs correction processing to the image data to correct distortion of the image to store the corrected image data in the line buffer. Further, the image forming apparatus forms images on a recording medium based on the image data having experienced the correction processing. The CPU of the image forming apparatus determines whether a size of the image data having experienced the distortion correction by a first correction value based on the sector correction seed value exceeds the number of lines in the line buffer. If it is determined that it exceeds the number of lines, the CPU obtains a second correction value, in which the first value is corrected.

主权项

1. An image forming apparatus, comprising:
a buffer configured to temporarily store image data; a correction unit configured to perform correction processing to the image data to correct distortion of an image to store the corrected image data in the buffer; an image forming unit configured to form an image on a recording medium based on the corrected image data; an obtaining unit configured to obtain a first correction condition to correct the distortion of the image; and a derivation unit configured to derive a second correction condition based on the first correction condition, wherein the second correction condition is derived, when a size of the corrected image data based on the first correction condition exceeds a predetermined size corresponding to a size of the buffer, such that size of the image having experienced the correction processing becomes smaller than the size of the buffer.
