Apple’s iPad Air Shows Higher Color Accuracy than the Retina iPad Mini
The Retina display on Apple’s recently released 7.9-inch iPad mini shows a smaller range of colors than the high-resolution screen found on the larger iPad Air and other competing tablets according to a recent analysis. In contrast to the unit’s otherwise impressive gains in resolution and performance, Apple seems to have chosen to equip the new iPad mini with a display that features the same narrow color gamut as its non-Retina predecessor as noted by the folks over at Anandtech
. The tablet was bested by Apple’s fourth-gen iPad and new iPad Air, as well as Google’s Nexus 7 and Nvidia’s Tegra Note 7 in testing.
For those of you who didn’t know, measuring color gamut in broad in broader terms means to measure the subset of colors a display can reproduce within a larger, predefined range. The iPads were subjected to tests that measured their ability to reproduce colors within the sRGB color space, an industry standard range of around 1 million colors designed to be used with computers. Differences in color reproduction are quantified with a measurement called Delta-E, which represents the difference between the color the display is asked to reproduce and the color the display actually shows.
The Retina iPad mini managed an average Delta-E of 6.5 across the gamut, compared to the iPad Air’s 2.4 and the Nexus 7’s 3.3. Delta-E values of approximately 2.0 or lower are considered unnoticeable to the human eye, while professionals who require display color accuracy, such as photographers and video editors, aim for Delta-E values of 4.0 or lower on their workstation displays.
The folks over at Anandtech
speculate that Apple believes consumers for whom color accuracy is a concern will choose the iPad Air over the smaller tablet by default, rendering the new iPad mini’s marginally narrow color gamut, a difference which calls “small but apparent,” a nonissue.
