  • Patent number: 8295595
    Abstract: A method and apparatus to remove color noise included in raw data while effectively preventing image quality degradation. For interest pixels serially set onto a mosaic image formed of raw data, conversion is executed into a pixel value for noise removal based on a processing reference pixel value having a unified color signal component in each interest pixel, noise is removed from the pixel value for noise removal, and the pixel value for noise removal with noise removed is converted into the source pixel value, whereby only color noise can be removed without affecting a luminance signal.

  • Patent number: 8098291
    Abstract: An image pickup apparatus performing moving-image data processing and still-image data processing in parallel includes an image pickup unit converting a ray into an electric signal and outputting an image pickup signal, a buffer unit temporarily storing the image pickup signal, a buffer controller controlling reading from the buffer unit, a first signal processing unit outputting a first transmission request, performing processing on the image pickup signal every frame timing in response to the first transmission request, and outputting moving-image data, and a second signal processing unit outputting a second transmission request, performing processing on the image pickup signal in response to the second transmission request at a predetermined timing, and outputting still-image data. The buffer controller determines whether it is possible that the image pickup signal is read without deteriorating continuity based on a data storage state of the buffer unit and the first and second transmission requests.
