Study on macro control technology of mobile phone imaging

In the process of mobile reading dot information based on halftone microstructure, in order to extract the feature information efficiently, we need to obtain a halftone image which microstructure is clearly distinguished. In this paper, mobile phone Macro imaging technology and algorithms are mainly studied. We present a method based on least square method for determining the image's clarity, as well as based on mobile phone camera macro imaging hardware control technology to solve the technical problem of mobile phone reading dot information under the Android platform. The experiments show that the methods and algorithms used in mobile phone reading dot information is effective.
