摘要： An image forming apparatus (110) or peripheral unit (100) connectable to an image forming apparatus (110), configured to perform a predetermined process, wherein the image forming apparatus (110) or peripheral unit (100) has a plurality of different preparatory operation patterns, which differ in relation to combinations of power and time.
The peripheral unit (100) is a pre-processing device for performing a predetermined process, or a post-processing device for performing a predetermined process.
The image forming apparatus (110) can comprise a recognition device (57) to recognize a type of peripheral unit (100) connected to the image forming apparatus (110), and can select a preparatory operation pattern from the plurality of different preparatory operation patterns for each type of peripheral unit (100). The image forming apparatus (110) itself may have a plurality of different operation patterns, differing in relation to combinations of power and time, and be configured to select preparatory operation therefrom and to perform the preparatory operation pattern based on types and combinations of peripheral units (100) connected to the image forming apparatus (110).

摘要： An image-reading device (1) is provided. The image-reading device (1) comprises a photoelectric converting element (25) reading a first image from a subject copy (D), a reference-white member (12) functioning as a reference white used in a white-shading correction, reading means (4) for reading a second image from a constant range on a surface of the reference-white member (12) by using the photoelectric converting element (25), averaging means (44; 22) for dividing image data of the second image into a plurality of blocks in a sub-scanning direction so that each of the blocks includes a plurality of lines and obtaining average values of image data of the lines in the blocks respectively, peak-value determining means (45, 46; 22) for obtaining a peak value of the average values, and white-shading correcting means (43; 22) for performing the white-shading correction to image data of the first image by using the peak value as white-shading data.
