Perceived Image Quality on Mobile Phones with Different Screen Resolution

Abstract

The diverse display screen imposes significant challenges for assessing the perceptual media quality across different mobile devices. In this paper, the perceived image quality on different mobile phones is investigated. Firstly, subjective experiments for image quality evaluation are implemented on 9 popular mobile phones and a broadcast-quality monitor to evaluate the impact on perceived image quality regarding the screen resolution, screen size, image resolution, and image coding quality. Furthermore, the effect of mutual interaction between the image resolution and screen resolution is analyzed and an integrated assessment parameter is proposed to establish a device-dependent image quality assessment model. This model can be used to predict the user’s perceptual quality of the images displayed on different mobile devices. Experimental results using twofold cross-validation indicate that the proposed model can accurately estimate users’ perceived image quality on mobile devices.

“…Popular resolutions of the time of these studies were 320p or 480p, which rarely appear on contemporary mobile devices. In an effort to investigate the same issue on screens larger than 5.7 inches and resolutions of 1440p (2K) or 2160p (4K), a recent subjective study [60] focused on more recent mobile devices having larger resolutions and screen sizes. The contents viewed by the subjects were re-scaled to 4K.…”

“…Furthermore, the study by Lischke et al [12] included, in addition to text, comparisons between images and video quality assessment and concluded that the three tasks have significantly different requirements in terms of pixel density. Additionally, considering specifically the video signal, other studies [13], [14] analyzed the assessment of video sequences including the possibility that the mobile device and the size of the screen may have some influence. Furthermore, the works by Ou et al [15], and Laghari et al [16] examined the influence of video characteristics and format in the user QoE, with a huge statistical analysis based on subjective assessment.…”
