Samsung Electronics’ image sensor experts have embraced a high challenge: reproducing a photograph obtained with Samsung’s 200-megapixel (MP) mobile image sensor on a massive 616 square meter canvas.
Continue reading to find out how the 28-meter-wide, 22-meter-high image (about one-and-a-half basketball court) was created.
“Our ambition to properly test the limits of the high-performance 200MP image sensor and its image quality is what prompted this challenge,” said Changwon Kim, project manager for Samsung Electronics’ Device Solutions Division’s Global Marcom Team.

“I’ve always wondered how big you could go when printing out a 200MP image,” said Minhyuk Lee, an engineer at Samsung’s System LSI Business’ Sensor Solutions Team. “As exciting as the task was, it was also challenging because it was our first time proving the quality of a yet-to-be-released image sensor.” deployed in smartphones.
Taking a photo with an image sensor that is still in development for a camera module that isn’t fully tuned is a difficult undertaking. Nonetheless, rather than dealing with an inanimate item, the team chose to push themselves by working with a real, moving subject.
“It was a difficult decision to choose a cat as our topic. “It presented us with a lot of challenges, such as recording such an active topic with a test board,” Minhyuk Lee explained. “However, the team came to the conclusion that the topic should be one that would demonstrate a high degree of detail while still being a popular photographic subject.”
While preparing to film in an uncertain environment, the team analyzed various factors. They also designed a bespoke adapter to connect multiple DSLR camera lenses to a test board. “In the end,” Sensor Solutions Team member Kaeul Lee explained, “We felt it was most important to capture the picture in the same settings that smartphone users would utilise.” be in.” “As a result, we decided to employ a smartphone camera module with no extra help.” The end product was fantastic.”
The photographer reviewed the screen and changed the composition because the shot was taken using a test board. The developers then tweaked the parameters to improve exposure and focus. After studying the cat’s activities, the camera crew employed a variety of techniques to capture a sequence of images. Hyunjoong Kim, a photographer, was excited to see the results because 200MP resolution is hard to come across, even with DSLR cameras. “When I saw the raw image blown up to 100%, I couldn’t believe my eyes,” Hyunjoong Kim remarked. “I was blown away by the level of detail. “Any preconceived notions I had about smartphone photography had been disproved at that point.”
The printing procedure was not simple, as a 616 square-meter picture cannot be reproduced in its entirety. The image had to be printed on twelve separate 2.3-meter-long cloth pieces before being put together. The printout was then hauled across town on a truck and crane-installed on a building’s wall.
“The entire enormity of the painting struck me when it was unfolded for the big unveiling, and not simply because of its literal size,” Changwon Kim stated. “I was astounded by all of the work that had gone into generating this final product when I saw the 200 million pixels portraying the exquisite detail of the cat’s eyes and fur.”
The crew was enthralled by the prospect of properly envisioning the next-generation potential of 200MP technology. Samsung’s position in the high-resolution industry will continue to grow in the future.
“The ultimate benefit of the 200MP picture sensor is that it allows users to take images that can be zoomed in and cropped without sacrificing image quality,” Kaeul and Minhyuk Lee concluded. “In the near future, the 200MP image sensor will be the finest choice for filming 8K video.”
