Video recording technology has been developed that reproduces colors as the world appears through the eyes of animals. The academic community expected that it would be of great help in understanding the visual organs of animals.
A joint research team from George Mason University in the United States and the University of Sussex in the United Kingdom introduced the so-called “animal-eye-view” technology through official channels on the 23rd, which reproduces the world seen through the eyes of animals.
The “Animal Eye View” system, which combines software developed by the research team and a general-purpose video camera, allows you to record videos of the world as the animal sees it. The research team emphasized that through this we can learn how various animals recognize objects and distinguish colors.

‘Animal Eye View’, also featured in the world-renowned biology journal ‘PLOS Biology’, reproduces the views of various animals, including insects such as bees, birds, mammals and reptiles.
Professor Daniel Hanley, a biologist at George Mason University who participated in the study, said: “Other animals don’t see the same scenery that humans see, because living things have different organs that can perceive light. For example, ultraviolet rays are not visible to the human eye.” “But it is clearly visible to the eyes of bees and birds, so there is a difference.”
“Knowing what the world appears to animals other than humans is important information for understanding animal ecology. How we see colors and signals is essential for various animals to communicate and navigate the world around them.” .

The photo above is a drawing of a peacock’s wings taken with ‘Animal Eye View’. A is the peacock, B is the human, C is the bee and D is the dog. This photo clearly shows that even when looking at the same thing, there are clear differences in the results depending on the animal’s visual organs.
So far, numerous devices have been developed that reproduce the world seen by animals. However, since most of them were still images, i.e. photos, there were limitations in fully understanding the animal’s perspective.
‘Animal Eye View’, which is based on multispectral imaging techniques, simultaneously records blue, green, red and ultraviolet rays. The technology to capture the world seen by animals in video rather than photos is unprecedented.

This photo shows how a bee recognizes a human arm covered in sunscreen. The color of human skin appears no different from the human eye or the bee’s eye.
However, when applying sunscreen, it’s a different story. The blocking portion appears yellow only to bees. Due to the effect of the blocker, the blue color of ultraviolet rays is weakened, while the green and red colors remain the same, creating a difference in the vision of humans and bees.
The research team’s position is that the video captured by “Animal Eye View” is 92% accurate to the actual view of the animal. The research team plans to release the “Animal Eye View” software as open source so that more scholars, especially amateur science enthusiasts, can use it usefully.
