Researchers at TAU ​​tech tech to capture images of subjects in motion

Researchers at Tel Aviv University have developed a process for photographing moving objects, providing clear, sharp images of the subject without focus without motion, the university announced Tuesday. ‘always mentions the speed of the object built. “, explains engineering PhD candidate Shay Elmalem, who led the research. “If you take a picture of a racing car, even a tenth of a second display could be too long, and if you are taking pictures of a man walking, a long display could take a second or longer. “According to the traditional camera design method, the lens is designed to produce the best image, i.e., the ones most similar to what the human eye sees, followed by digital image processing algorithms. applied to remove the optical distances, “Elmalem added. “However, as anyone with a built-in camera knows their phone, this is not always effective; so it’s still very difficult to take pictures of moving objects.” the image processing algorithms work and completely designed the optical elements to create the new innovation. The tech describes the movement clarifies and encodes information within the raw image, which is then coded using the algorithm to provide a clear, sharp image. He also works on technology to restore the colors of the images, observes when an object moves all the colors together, and actually replaces the colors to give the image. to look like a small picture in time. “In every slice of exposure, our lens generates a slightly different image,” Elmalem said. equals, but it will gradually change with its movement. “” To understand where and how fast the object in the image is going, we will use color. So, for example, abruptly throwing a white ball into the frame with different colors over its movement, like passing light through a prism, “Elmalem added. “Based on these colors, our algorithm knows where the ball has been thrown from and at what speed.

“So you know how to correct the blindness. With a regular camera we would see a white watch that would damage the sharpness of the whole picture, but with our camera the final image will be a bright white ball. with focus. “
