A research team from the University of Sussex in the United Kingdom and the Henley Color Laboratory at Mason University in the United States have developed a new imaging system that provides the opportunity to see the world from the animal's perspective. The camera lens captures the color scene seen by animals with more than 90% accuracy, which will contribute to scientists' understanding of the visual experiences of different living organisms.
Due to differences in eye structure, what the human eye captures within the spectral range differs from that of other animals. For example, there are animals that are able to see ultraviolet rays, which is outside the range of vision of the human eye.
Studying what animals see helps us learn more about the details of life and the ways they communicate and move around in their environments. While advanced and modified color images can show us part of the world, older methods like spectrophotometry take a lot of time, require specific lighting, and cannot capture moving objects.
To overcome these obstacles, the research team developed a modern camera with a software system that can photograph moving objects from the animal's perspective. The camera relies on the feature of multiple simultaneous recording on 4 channels: blue, green, red and ultraviolet. This data can be processed through a “perceptual module” to produce an accurate video that simulates the animal's ability to see based on current knowledge about photoreceptors in the eyes.
Researchers say the modern imaging system will open new horizons of research for scientists, and allow filmmakers to create dynamic and accurate images of how animals see the world around them. The designed system is commercially available, allowing other researchers to use and build upon the technology in the future.
The study's lead researcher, Daniel Hanley, notes that humans have long been interested in how animals see the world in all its details, and that animals often make important judgments about moving targets and objects, such as Searching for food or evaluating the behavior of a potential object. Friends, etc. Therefore, researchers provide necessary equipment and software to ecologists and filmmakers, which will provide them with a simulation of seeing moving objects from the animal's perspective.
