Image forming apparatus and image forming method

摘要

A device for controlling an image forming apparatus includes an acquisition unit configured to acquire image data, and pixel piece insertion/extraction information indicating whether a pixel piece needs to be inserted into or extracted from each pixel of the image data, a generation unit configured to generate an exposure signal according to a pixel value indicating a pixel of interest in the image data and to pixel piece insertion/extraction information on the pixel of interest, and a control unit configured to control exposure by the apparatus according to the exposure signal. The generation unit causes the pixel of interest to be formed by a plurality of pixel pieces arranged in a direction in which the apparatus scans, presets at least one of the pixel pieces as an adjustment blank pixel piece, and deletes the piece when the width of the pixel of interest in the scanning direction is reduced.

主权项

1. A control device for controlling an image forming apparatus configured to form an image, the control device comprising:
an acquisition unit configured to acquire image data formed by pixels each including a plurality of pixel pieces, and pixel piece insertion/extraction information indicating whether a pixel piece needs to be inserted into or extracted from each pixel of the image data; a generation unit configured to generate an exposure signal used by the image forming apparatus to carry out an exposure, according to a pixel value indicating a pixel of interest in the image data and to pixel piece insertion/extraction information on the pixel of interest; and a control unit configured to control exposure by the image forming apparatus according to the exposure signal, wherein the generation unit causes the pixel of interest to be formed by a plurality of pixel pieces arranged in a direction in which the image forming apparatus performs exposure scanning, and presets at least one of the plurality of pixel pieces as an adjustment pixel piece that stays blank, and wherein the generation unit extracts the adjustment pixel piece when the width of the pixel of interest in the scanning direction is to be reduced.
