  • Patent number: 8280190
    Abstract: To provide a processing method for reducing motion blur while increasing resolution. By performing a super-resolution process, a resolution-increased image is obtained from an input image in multiple frames. By performing an enlargement process, an enlarged image is obtained from the input image in one frame. A high-frequency image is obtained by subtracting the enlarged image from the resolution-increased image. A high spatial frequency-emphasized image is obtained by adding the high-frequency image to the resolution-increased image. The enlarged image and high spatial frequency-emphasized image are displayed alternately every half frame.

  • Patent number: 8224123
    Abstract: A technique is provided for reducing the size of each of images included in an image signal and generating a high-resolution image with minimized degradation in the image quality from the reduced images. Alias components and motion information that are included in the image signal having the reduced images are used for conversion of the images included in the image signal into a high-resolution image. Low pass filtering is performed on a frequency component in the direction of a motion included in the image signal and a frequency component in a direction other than the direction of the motion. The cut-off frequency of the low pass filter in the direction other than the direction of the motion is lower than the cut-off frequency of the low pass filter in the direction of the motion.

  • Patent number: 8212927
    Abstract: The present invention relates to a technology of appropriately improving image resolution. According to an image signal processing method of the present invention, an input video signal contains an image signal whose pixel size is converted at a specified magnification scale. The input image signal is used to calculate sampling frequencies for image signals before and after the pixel size conversion. A ratio of sampling frequencies before and after the pixel size conversion is used to determine the specified magnification scale. A sampling phase for the image signal before the pixel size conversion is calculated from the input image signal after the pixel size conversion. A sampling carrier for the image signal before the pixel size conversion is generated from the sampling frequency and the sampling phase both before the pixel size conversion.
