Patent number: 8290041Abstract: A communication terminal performs a discrete cosine transform and a quantization process in accordance with a selected coding mode so as to reduce loads caused by these processings and suppress degradation of picture quality. When performing coding of a moving picture inputted through a picture input part, a control part determines which coding mode among 4×4 intra prediction coding on a luminance signal, 16×16 intra prediction coding, intra prediction coding on a color-differential signal, and inter prediction coding is performed. In accordance with the selected coding mode, and in view of a predictive error, the processing content in the discrete cosine transform and the quantization process is switched.Type: GrantFiled: July 5, 2007Date of Patent: October 16, 2012Assignee: Kabushiki Kaisha ToshibaInventors: Shingo Suzuki, Yoshihiro Kikuchi, Yuji Kawashima

Patent number: 8270484Abstract: An information processing apparatus is presented that includes a first determination unit which determines whether a processing target frame is a frame of a predetermined type and a second determination unit which determines whether an interval between the frame and a frame of the predetermined type located temporally nearest in the forward direction, exceeds a predetermined frame count. In addition, a conversion unit is included which converts the processing target frame into a frame of the predetermined type, when the second determination unit determines that the interval exceeds the predetermined frame count.Type: GrantFiled: June 24, 2008Date of Patent: September 18, 2012Assignee: Kabushiki Kaisha ToshibaInventors: Yoshihiro Kikuchi, Tatsuro Fujisawa, Yuji Kawashima, Makoto Oshikiri

Patent number: 8189667Abstract: In a moving picture encoding apparatus, a processing load detection section detects a load and outputs load information and a video encoder judges a load level based on the load information. A start pixel in target pixels is determined depending on the load level, the evaluation value is calculated from pixels specified by the start pixel, a encoding cost is calculated based on the evaluation value to select one of prediction modes for minimizing the encoding cost. The start pixel is so selected as to exclude the pixels which are spatially neighboring to reference pixels for prediction, instead of all pixels within a 4×4 pixel block as the processing load becomes large. Thus, the picture processing amount is reducing while suppressing the deterioration of the encoding performance.Type: GrantFiled: April 30, 2007Date of Patent: May 29, 2012Assignee: Kabushiki Kaisha ToshibaInventors: Yuji Kawashima, Yoshihiro Kikuchi, Shingo Suzuki

Patent number: RE42500Abstract: An input image signal is coded by an encoder to be outputted as a basic code string, and the basic code string is delayed by a code-string delay circuit for a predetermined period of time to be outputted as an additional code string. The basic code string is synthesized with the additional code string by a code-string synthesizer to be outputted as an output code string. Thus, there is provided an image data coding system which can quickly restore data even if the data is lost due to error and in which the increased code amount is less than the cycle refresh and the error correction.Type: GrantFiled: September 18, 2008Date of Patent: June 28, 2011Assignee: Kabushiki Kaisha ToshibaInventors: Takeshi Nagai, Kenshi Dachiku, Takeshi Chujoh, Yoshihiro Kikuchi, Toshiaki Watanabe
