Publication number: 20100128978Abstract: The image processing apparatus according to the present invention includes a local skin color level calculating section, a local brightness deviation calculating section, and a correction amount calculating section. The local skin color level calculating section calculates, as a local skin color level, a skin color level in a predetermined local region in an image. The local brightness deviation calculating section calculates, as a local brightness deviation, a brightness dynamic range in the predetermined local region. The correction amount calculating section determines whether the predetermined local region is a skin region or not by using the local skin color level and the local brightness deviation.Type: ApplicationFiled: August 17, 2007Publication date: May 27, 2010Applicant: MITSUBISHI ELECTRIC CORPORATONInventors: Yoshiki Ono, Kazuhiro Sugiyama, Yoshiko Kurahashi

Patent number: 7652689Abstract: In a digital still camera, the amount of blur when a picture is taken is calculated from a first picture captured with a high-speed electronic shutter and a second picture captured with a normal shutter speed (5), and the blur in the picture captured with the normal shutter speed, which is degraded by the blur, is corrected through digital signal processing, by applying a picture restoration algorithm (6). Blur can be corrected by a simple device, without requiring an angular velocity sensor or a circuit to process its output in order to reduce the effect of camera shake.Type: GrantFiled: April 26, 2005Date of Patent: January 26, 2010Assignee: Mitsubishi Electric CorporationInventors: Naoyuki Fujiyama, Tetsuya Kuno, Kazuhiro Sugiyama

Patent number: 6922490Abstract: An image encoding device is provided that can transmit encoded image data without lowering the frame rate even when the transmission speed of the transmission path is lowered. An encoded region designator selects the region that is to be encoded, in the input image, depending on the bit rate of the transmission path. Only such a region that is designated by the encoded region designator is encoded. The encoded region designator may be one which selects the region that is to be encoded, according to the bit rate of the transmission path, and the motion vector detected by the image encoding circuit. As an alternative, an encoded region designator may be used which selects the region that is to be encoded according to the bit rate of the transmission path, and the information on the designated region supplied from the outside.Type: GrantFiled: March 26, 2001Date of Patent: July 26, 2005Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Tomoaki Ikeda, Mamoru Inamura, Junko Kijima, Yoshiko Hatano, Kazuhiro Sugiyama

Patent number: 6795503Abstract: As the video signals of macroblocks are coded, they are stored in a buffer. When the total code length of the stored macroblocks exceeds a predetermined value, all but the most recently coded macroblock are output from the buffer as a video packet, and the most recently coded macroblock is coded again. To minimize this occurrence, when each coded macroblock is stored, the code length of the next macroblock is predicted and added to the total length, and if the resulting sum exceeds the predetermined value, all of the coded macroblocks stored in the buffer are output as a video packet.Type: GrantFiled: March 7, 2001Date of Patent: September 21, 2004Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Takashi Nakao, Yoshiko Hatano, Junko Kijima, Kazuhiro Sugiyama

Patent number: 6700571Abstract: A matrix-type display device has a matrix display panel, a frame memory, and a graphics memory. Input image data are temporarily buffered in the graphics memory, then transferred to the frame memory and read out to drive the matrix display panel. Readout from the frame memory is cyclic, and is synchronized with a frame synchronization signal. A synchronizing circuit also synchronizes the transfer of data from the graphics memory to the frame memory with the frame synchronization signal, so that each displayed frame is generated from a single frame of image data, and not from parts of two different frames. Moving images can therefore be reproduced faithfully. This matrix-type display device is useful in mobile information-terminal equipment, such as mobile telephone sets.Type: GrantFiled: September 26, 2001Date of Patent: March 2, 2004Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Hidehiko Nakatani, Kazuhiro Sugiyama

Patent number: 6590601Abstract: A videophone takes a live picture of the user, sends the live picture during part of a call, generates a processed picture different from the live picture, and sends the processed picture during another part of the call. The processed picture may be prepared in advance, or may be generated by combining the live picture with a prepared picture. Alternatively, the processed picture may be obtained by increasing a quantization coefficient of the live picture, producing a mosaic effect that disguises the live picture. The processed picture can be sent to protect the privacy of the videophone user, or to provide appropriate transition at the beginning or end of the call. The processed picture can also be sent when the call is placed on hold.Type: GrantFiled: February 21, 2001Date of Patent: July 8, 2003Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Junji Sukeno, Yoshiko Hatano, Takuji Kurashita, Tadashi Minobe, Kazuhiro Sugiyama
