20080309778 | Shutter time compensation - A hybrid imaging device is configured to capture low resolution video and high resolution still images. The imaging device is configured to apply motion information obtained from the low resolution video to a reference high resolution still image to generate a missing moment of interest high resolution still image. The low-resolution video is captured at a high frame rate in conjunction with a few high-resolution still pictures taken at periodic intervals. A user locates a desired scene of interest, e.g. a moment of interest, from the captured video, and a post-processing technique is used to generate the high resolution still picture corresponding to the selected moment of interest. The high resolution still image is generated using texture information from one or more nearby captured high resolution still images and motion information from the low-resolution video frame corresponding to the selected moment of interest. | 12-18-2008 |

The present invention is applied to an encoder for encoding image information and a decoder for decoding image information. | 06-05-2014 |
20140307797 | IMAGE INFORMATION ENCODING METHOD AND ENCODER, AND IMAGE INFORMATION DECODING METHOD AND DECODER - An image decoding method includes decoding encoded image data to generate a decoded image signal including a luma signal and a chroma signal. The method further includes scaling, when a reference field has a different parity from a current field for motion compensation and when the decoded image signal is in a format in which the number of chroma pixels is vertically different from the number of luma pixels, a chroma motion vector of the chroma signal according to an accuracy for a luma motion vector of the luma signal so that a reference frame will coincide in phase of the chroma signal with a current frame. The method also includes performing motion compensation of the decoded image signal using the scaled chroma motion vector according to the accuracy of the luma motion vector of the luma signal. | 10-16-2014 |
