Abstract

The embodiment of the invention provides a portrait correction method, an image forming device and a storage medium. The method comprises the following steps: acquiring a first end color density value and / or a second end color density value of a correction reference image along a to-be-corrected direction; performing difference value calculation on the first end color density value and / or the second end color density value and a target color density value to obtain a first end color density difference value and / or a second end color density difference value; if the first end color density difference value and / or the second end color density difference value are / is greater than or equal to a preset difference value threshold value, performing uniformity correction on the to-be-corrected image. By adopting the scheme provided by the embodiment of the invention, uniformity correction can be carried out on the image forming device with relatively poor uniformity, so the image printed by the image forming device has a relatively good uniformity effect. In addition, according to the correction scheme provided by the embodiment of the invention, the printing efficiency can be prevented from being influenced by multiple times of measurement or correction, and the measurement time and cost are saved.

Description

technical field [0001] The present application relates to the technical field of image formation, and in particular to an image correction method, an image forming device, and a storage medium. Background technique [0002] An image forming device is a device that forms an image on a recording medium by the principle of imaging, such as a printer, copier, facsimile machine, multifunctional image making and copying device, xerographic printing device, and any other similar devices. [0003] The photosensitive component is one of the most important components in the developing and imaging process of the image forming device. A common photosensitive component includes a photosensitive drum whose surface is coated with photosensitive material. When the laser scanning unit (LSU, Laser Scanning Unit for short) irradiates the surface of the photosensitive drum, the resistance of the irradiated part becomes smaller and the charge disappears; The areas irradiated by the scanning uni...
