1. A method for correcting image data of an external imaging device in an image processing apparatus to reduce maintenance cycles of the image processing apparatus, the method comprising: obtaining, by the image processing apparatus, formatted information related to the external imaging device, the formatted information including a correspondence table that includes information that indicates a first configurable processing model corresponding to at least a first attribute of the external imaging device from a plurality of attributes of the external imaging device and other external imaging devices, each of the attributes corresponding to a software element of a respective external imaging device that results in at least one predetermined variable defect being applied to digital images captured by the respective external imaging device, such that the first attribute results in a first predetermined variable defect being applied to digital images captured by the external imaging device; receiving, by the image processing apparatus from the external imaging device, a first digital image captured by the external imaging device separate from the formatted information, wherein the first digital image includes the first predetermined variable defect, which is caused by the first attribute of the external imaging device; determining a first identifier from the correspondence table of the formatted information, wherein the first identifier corresponds to a variable of a measurable factor that varies amongst the digital images captured by the external imaging device, the variable influences a variable defect of the digital images and influences the first predetermined variable defect included in the first digital image, the first identifier identifies a field including a value of the variable, said field is included in the first digital image or in a file that includes the first digital image, and said field is not included in the correspondence table; determining a second identifier from the formatted information to locate the first configurable processing model for the first attribute by the information included in the formatted information, from a plurality of configurable processing models for the plurality of attributes of the external imaging device, to correct the first predetermined variable defect of the first digital image; after said step of determining the first identifier, determining, by reading, in the first digital image or in the file that includes the first digital image, the field identified by the first identifier, including the value of the variable corresponding to the first digital image; and correcting, by the image processing apparatus, the first predetermined variable defect of the first digital image by executing the first configurable processing model, as identified by the second identifier, in accordance with the value of the variable corresponding to the first digital image, as identified by the first identifier.
