Latest Patents

“Image Processing Device and Imaging Device Including the Same” describes technology for generating parallax images used in autofocus. The device combines pixel data from corresponding unit pixels across multiple pixel groups to create color images. It then calculates weights using texture amplitudes and correlations among those images, applying the weights to generate a luminance image.

“Image Signal Processor and Image Signal Processing Method” concerns processing image signals while controlling noise reduction. The system performs remosaic processing on an input image, estimates noise in the converted image, determines a noise-reduction degree, and uses that information to produce an output image with controlled noise suppression.

Career Highlights

Yahata’s listed inventions address image quality and processing challenges, including autofocus-related parallax generation and noise management in converted images. These technologies reflect work in imaging systems and image-signal processing.
