The mobile network technologies are continuously evolving towards high bandwidth, QoS enabled, mobility rich 4G solutions that will revolutionize capabilities of novel services in wireless networks. In parallel the end-terminals portfolio has exploded with devices providing greater functionality and usability with more processing power on board. Panoramic displays touch screens and TV-out ports are steps towards providing improved user satisfaction. It is estimated that half of all handsets sold will be "smart" in four years and by 2015 almost all will be. The above trends combined with the shift towards cloud computing, software as a service and mobile commerce puts higher pressure on the HTTP based services. However the real user experience is not only driven by combined performance of underlying access network and terminal characteristics. The complexity of internal processing of a web browser used to render data to a user may influence the quality of experience (QoE). Thus to assess the real user experience of the HTTP services it is not enough to analyze packet level metrics on the mobile terminal (or inside network) as implementation of various browsers may affect efficiency of data rendering differently. Authors propose the novel idea of applying concept of image processing to the analysis of visual information as originally seen by the end user on the mobile terminal's screen. The paper presents the concept, system design, verification and validation and preliminary results of the proposed techniques. Results presented show that the use of image processing techniques has numerous advantages against complementary user assisted measurement techniques for objective QoE measurement.
