Comparing Samsung and Apple Top-End Mobile Cameras by Using NR-IQA Metrics

In this work, we compare the picture quality provided by two popular smartphone brands: Samsung and Apple. We use the top-end model of both brands in 2022: Galaxy S22 Ultra for Samsung and iPhone 13 Pro for Apple, and we built a dataset consisting of seven different environments. For each of these environments, we captured pictures with both devices under the same conditions in two camera categories: first, using the device’s native camera and then using the camera provided by the Instagram App. Since these pictures are in a compressed form, and therefore there is no reference image to compare them to, we use “No-Reference Image Quality Assessment” (NR-IQA) metrics to provide values to measure the quality of its pictures. Experimental results with some of the most used NR-IQA metrics show that Samsung device has best images for most of the environments when using the device’s native camera, but Apple provides best results for the Instagram App.
