Latest Patents
Hirakawa's latest patents include innovative methods for displaying video data on devices. One of his patents describes a display method that utilizes a first Electro-Optical Transfer Function (EOTF) to define luminance in HDR video. This method involves acquiring video data and performing a conversion to match the dynamic range of a third EOTF. The process ensures that the maximum luminance of the second EOTF aligns with the display device's capabilities while preserving the relative luminance relationships.
Another patent outlines a dual tone mapping technique for video pixels. This method determines whether the luminance of each pixel exceeds a predetermined threshold and applies different mapping formats accordingly. The results of this dual tone mapping are then used to display the video on the device, enhancing the overall viewing experience.
