Latest Patents

Iwaki's latest patents include an image processing method, image processing apparatus, and image processing program. In his image processing apparatus, an input transform into an input color space is performed on input image data. After this transformation, processing is conducted to adjust the chroma or chromaticity of the input image data. This adjustment aims to minimize the difference between the chroma or chromaticity spaces, resulting in transformed image data. Finally, an output transform into an output color space is executed using a three-dimensional lookup table, which includes inverse transform processing to revert the chroma or chromaticity back to the original input image data.

Another notable patent involves a video conversion device and a photography system that employs this technology. The video conversion unit consists of several components, including a unit that acquires camera video data signals and a first color conversion unit that translates these signals into a photography scene reference color space. This process derives first video data, which undergoes lock modification before being converted into a video output reference color space. The final step involves converting this data to a color space suitable for verification display devices, ensuring accurate color representation across different devices.
