Since this resolution is typically assessed using an eye chart at a distance of 20 feet, this level of performance is defined as 20/20 vision. Human vision is generally described in terms of “ angular resolution” as on the graph below:īeing able to resolve lines in characters that are separated by 1/60th of a degree (an “arc minute”) is the goal when testing eyesight. Human visual perception of detail does not solely depend on the ability of our eyes to resolve the smallest features in a given subject, but also depends on the distance between us and the object being projected. Below we’ve included some insights on the subject, courtesy of the learning resources on RED.com In this post, we’ll consider some factors which affect 4K viewing and our human visual perception, in order to achieve a more worthy viewing experience. So, does 4K really have an impact on the human eyesight, and can we really benefit from a 4K (UHD) viewing experience? However, as the so-called “K” wars (or resolution wars if you want to call them) continue between camera manufacturers, consumer perception and reactions to 4K as the next home entertainment standard seem to be mixed at best. Many consumers cannot even distinguish between HD and 4K content displayed on a 40+ inch TV, which is one of the major arguments against the need for 4K TVs. There are numerous improvements required on many fronts, one of them being availability of 4K content and increased demand from consumers, but it time this will happen as we have the acquisition and display tools on hand.ĤK TV sets started popping up just in the last two three years, but display technology has already made significant improvements. Today, prices on consumer 4K displays are constantly falling, and it won’t be long before we see very good quality 4K TV’s at reasonable prices. From SD to HD, and now making a quantum leap into 4K resolutions and beyond, it sometimes makes me wonder where do we go from here. We’ve come a long way in the last decade. ![]()
