Development of visibility enhancement for projector display in bright rooms
Hitachi, Ltd. today announced the development of video processing technology enhancing the visibility of high resolution at a rate of 60 frames per second. Enhanced visibility video display was achieved by analyzing the visual characteristics of the video signals to be displayed, extracting key components contributing to visibility, and enhancing those components. As a result, good visibility of projector displayed video can be achieved without increasing the brightness of the projector light source. To enable this technology to be embedded into various products, the processing algorithm for the hardware structure was optimized, achieving real-time processing of high-resolution video in compact hardware. The technology was first developed for the projector but as it can also enhance visibility in surveillance monitors and vehicular displays, it is expected to find a wide range of application.
