A method and a system are provided for replacing the theme of a mobile terminal on the basis of a user's clothes color, including: setting an RGB value interval of clothes through analyzing the RGB values of all pixels of the clothes location in the obtained image and calculating the clothes RGB average, analyzing the RGB values of all pixels of every theme on a mobile terminal, calculating the theme RGB value average; when the theme RGB average is within the clothes RGB average interval, and replacing the theme of the mobile terminal by the theme corresponding to the theme RGB average. Thus, the mobile terminal becomes more interesting.

Image compensation value computation techniques are described. In one or more implementations, an image key value is calculated, by a computing device, for image data based on values of pixels of the image data. A tuning value is computed by the computing device using the image key value. The tuning value is configured to adjust how the image data is to be measured to compute an image compensation value. The image compensation value is then computed by the computing device such that a statistic computed in accordance with the tuning value approaches a target value. The image compensation value is applied by the computing device to adjust the image data.

A printing processor receives print job instructions to combine variable printing information and fixed data to build a print job to be printed using a printing engine. The variable printing information is unrasterized-type data. The printing processor evaluates the print job instructions to determine whether the configuration of the variable printing information is compatible with configurations of different fixed data forms (the fixed data forms are rasterized-type data). The graphic user interface displays menu selections of only the fixed data forms determined to be compatible with the configuration of the variable printing information.
