Abstract: A picture obtaining method and apparatus and a picture processing method and apparatus are provided. The method includes: obtaining a grayscale image corresponding to a first picture and a first image, where a size of the first picture is equal to a size of the first image, the first image includes N parallel lines, a spacing between two adjacent lines does not exceed a spacing threshold, and N is an integer greater than 1; translating a pixel included in each line in the first image based on the grayscale image, to obtain a second image, where the second image includes a contour of an image in the first picture; and set a pixel value of each pixel included in each line in the second image, to obtain a second picture.

Abstract: The present invention provides a method for generating a bill, a method for transferring a bill, a system for transferring a bill, a device for generating the bill, a switching device and a charging collection function (CCF), the main solution of which includes: setting bill transfer configration information according to the bill information units that need to be contained in the bill and generating the bill to be transferred according to the bill transfer configuration information. In accordance with the present invention, the bill information units can be set on the practical demands, so that the generated bill is of configurability, and the record length of the bill become changeable, thereby avoiding the storage and transfer for unnecessary bill information units.
