This paper presents a new model based on the sub-block histogram information for cross-detection algorithm of the camera. Algorithm for each image frame block for histogram, and then frame the use of adjacent sub-block histogram corresponding statistics for the amount of information interaction, and finally all of the interactive block to the weighted average amount of information to detect changes in lens . The experimental results show that compared with the traditional histogram, the algorithm for general scenes of the lens changes in higher recall rate and precision.
