Logic & Design has released the Sea Filter algorithm. The Sea Filter algorithm is a technology that optimizes the phenomenon of green and blue being emphasized in the ocean to natural colors in real time.

It is promoted as the ideal technology for underwater cameras for underwater infrastructure inspections using underwater drones, marine environmental surveys, underwater aquaculture, etc., which have seen increasing demand in recent years.

By calculating the average color signal from real-time video, calculating the amount of color shift using a unique algorithm, and reflecting it in each pixel, it is possible to reduce the influence of specific colors in real time without relying on prior information. For example, even in a situation where the entire screen changes from green to blue, the color shift is performed in real time according to the change in the color signal, providing a natural and easy-to-see image. In addition, it is possible to appropriately eliminate the effects of sudden strong light and sudden color changes in an instant, making it possible to provide natural images without image distortion or breakdown in real time.
