20080199156 | APPARATUSES AND METHODS FOR PROCESSING VIDEO SIGNALS - Conversion information regarding a method of frame-rate conversion executed in an image pickup apparatus is attached to video data, and the video data with the attached conversion information is passed to a playback apparatus. In the playback apparatus, an optimal image processing method is selected according to the conversion information. | 08-21-2008 |
20080247654 | IMAGE CAPTURING APPARATUS, IMAGE PROCESSING APPARATUS AND CONTROL METHODS THEREOF - An image capturing apparatus determines an image frame to extract as a reference image frame from a plurality of image frames constituting a moving image, using a histogram, for example, and generates a reference image data file. An encoder unit encodes the plurality of image frames after reducing the resolution thereof, and generates an encoded moving image data file. A list associating the reference image frame with information specifying the corresponding reference image data file is generated with a content information list generating unit. The reference image data file, the encoded moving image data file and the list are then recorded. | 10-09-2008 |
20090160949 | VIDEO PROCESSING APPARATUS, VIDEO PROCESSING SYSTEM, VIDEO PROCESSING METHOD, AND PROGRAM - A video processing apparatus comprises a signal input unit which receives a video signal, a shift detection unit which detects a shift period in shooting and a maximum shift amount during the shift period from the video signal input from the signal input unit, an effective area detection unit which detects an object area common throughout the shift period as an effective area on the basis of the shift period and the maximum shift amount, a correction unit which corrects a shift during the shift period by reading out data from the effective area, and a resolution conversion unit which performs enlarge processing to convert a size of the effective area read out by the correction unit into an output image size. | 06-25-2009 |
20090310016 | VIDEO OUTPUT APPARATUS AND CONTROL METHOD THEREOF - There is provided a video output apparatus which inputs a video content that can have at least three different resolutions. A format detector ( | 12-17-2009 |
20090310780 | BROADCAST RECEIVING APPARATUS AND BROADCAST RECEIVING METHOD - Before a device key generation procedure is updated in response to execution of revoke, a recorded transport stream is decrypted using an unupdated device key and is stored in a memory unit after being re-encrypted. In this manner, broadcast programs that are recorded before the revoke can be viewed while maintaining a copyright protection function. | 12-17-2009 |
20100034378 | BROADCAST RECEIVING DEVICE FOR RECEIVING BROADCAST SIGNAL AND METHOD OF CONTROLLING THE SAME - Provided is a broadcast receiving device including a determining unit configured to make a determination on a channel selected by a selecting unit as to whether the corresponding encryption key is available or unavailable, and a control unit configured to, when the determining unit determines that the encryption key is unavailable, allow the selecting unit to sequentially select channels displayed in a channel window, allow the determining unit to make the determination, and allow an output unit to generate and output the channel window so that the channel with the encryption key determined as unavailable is identified. | 02-11-2010 |
20100119060 | RECEIVING APPARATUS AND METHOD FOR CONTROLLING THE SAME - The present invention provides a receiving apparatus including a device key generating unit which generates a device key, a work key generating unit which generates a work key, a device key storing unit which sequentially stores the generated device key, every time the device key is updated, and a recording unit which stores a digital broadcast signal in a transport stream format, wherein in a case where the device key generating unit cannot generate, from the stored transport stream, a device key necessary for descrambling the stored transport stream when the stored transport stream is to be reproduced, the work key generating unit decrypts an encrypted work key that is obtained from the stored transport stream, using the device key stored in the device key storing unit, and generates a work key. | 05-13-2010 |
20100226622 | VIDEO PLAYER AND VIDEO PLAYBACK METHOD - When multi-frame rate contents including many high frame-rate portions are played back in a video player, a playback can be easily selected by showing to a user a playback time in respective playback modes of a normal playback and a slow playback. The video player includes a rate analysis unit for calculating playback time in the respective playback modes by analyzing a frame rate of multi-frame rate contents, and thumbnail images of multi-frame rate contents and playback time in the respective playback modes are listed and displayed as display units in a pair with respect to a plurality of contents. | 09-09-2010 |
20130265323 | UNEVENNESS CORRECTION APPARATUS AND METHOD FOR CONTROLLING SAME - An unevenness correction apparatus according to the present invention comprises: a storage unit that stores correction tables, which are used for correction processing to correct unevenness on a screen of a display apparatus, for a plurality of division areas constituting an area of the screen respectively; and a correction unit that performs the correction processing on image data to be displayed on the display apparatus, using at least one correction table which includes a correction table for a division area including a target position of the correction processing, out of the correction tables for respective division areas stored in the storage unit, wherein a relatively large division area is set in a center portion of the screen, and a relatively small division area is set in an edge portion of the screen. | 10-10-2013 |
