Patent number: 7058228Abstract: Image data compression method and apparatus which improves image quality in a scene where image greatly changes and reduces the image data, and image transmission system and monitoring system using the method and apparatus. The image data compression apparatus which compresses input image data and outputs compressed image data comprises a detection unit which detects a motion or change of each scene, a determination unit which determines the detected motion amount or change amount, a switch circuit which controls a frame rate in accordance with the results of determination, and a compression encoding unit which compression-encodes the image data. The apparatus performs control such that an image having small motion amount and small change amount with respect to a predetermined image is not compression-encoded, so that the frame rate in a scene where the motion or change is large is higher than that in a scene where the motion and change are small.Type: GrantFiled: July 25, 2003Date of Patent: June 6, 2006Assignee: Hitachi, Ltd.Inventors: Toyota Honda, Masayoshi Kuroda, Shinya Imanishi, Koichi Takamoto, Yuichi Michikawa

Patent number: 6608938Abstract: An image data expansion apparatus including a decoder for decoding compressed image data at a frame rate controlled to be lower in a scene where the change is small than that in a scene where the change is large; an expander for expanding the compressed image data decoded by the decoder, the input image data being reproduced such that the frame rate is lower in a scene where the change between images is small than the frame rate in a scene where the change between images is large; and an image interpolator for generating an interpolation image from the input predetermined compressed image data in accordance with the information on the frame rate outputted with the compression image data. The reproduced input image data is interpolated with an interpolation image generated by interpolation processing by the image interpolator, and the interpolated image data is outputted.Type: GrantFiled: March 4, 2002Date of Patent: August 19, 2003Assignee: Hitachi, Ltd.Inventors: Toyota Honda, Masayoshi Kuroda, Shinya Imanishi, Koichi Takamoto, Yuichi Michikawa

Patent number: 6094186Abstract: In a document processing apparatus wherein when a format of a document or the like is set, a plurality of format patterns are simultaneously displayed, a selection is made of a desirable format pattern among said format patterns so as to perform a format setting operation, displays of the format patterns are subdivided into a plurality of screens based on a purpose or usage of a document to be formed. After selecting or designating the purpose or usage of the document, the above-described format pattern is displayed. The document format setting operation which was cumbersome in prior art can be readily performed by selecting a desirable format sample from the format samples which have been categorized based upon the usage thereof, and also by adding an item capable of freely setting a format into the format samples.Type: GrantFiled: May 15, 1995Date of Patent: July 25, 2000Assignee: Hitachi, Ltd.Inventors: Masayoshi Kuroda, Yasumasa Matsuda, Hiroyuki Kumai, Yasuhiko Kasai, Kiyoshi Masuda, Akihiro Kaneko, Junichiro Takeyama

Patent number: 5590872Abstract: A sheet reversing apparatus which has a take-in path, a reversing path which extends from the take-in path in a substantially same direction, a take-out path which extends from a junction of the take-in path and the reversing path in a substantially perpendicular direction to the extending direction of the reversing path. A sheet is fed from the take-in path to the reversing path, and when the trailing edge of the sheet comes out of the take-in path, the sheet is fed back from the reversing path to the take-out path. In an entrance portion of the reversing path, a first reversing roller which is driven to rotate in a feed-back direction toward the take-in path and a second reversing roller which is capable of coming into contact with and moving away from the first reversing roller are provided.Type: GrantFiled: March 29, 1995Date of Patent: January 7, 1997Assignee: Minolta Co., Ltd.Inventors: Taiichi Oominami, Toshio Sakata, Masayoshi Kuroda, Tomonobu Tamura, Masami Nakane, Kazuhiko Nakatsuka

Patent number: 5485261Abstract: There is disclosed an image forming apparatus capable of double-sided or overlay copying at high speed. While a sheet having initially copied a first original document is still being transported to an intermediate tray inside the apparatus, an image forming operation on a second document is started, and one of the initially copied sheets in the intermediate tray starts to be refed therefrom for secondary copying. If the designated number of copying sheets is larger than a predetermined value and when the number of times the image forming operation is performed has exceeded that value, the start of the subsequent image forming operation is delayed by a predetermined time so as to provide the currently transported sheet with an extended distance relative to the preceding sheet.Type: GrantFiled: July 25, 1994Date of Patent: January 16, 1996Assignee: Minolta Co., Ltd.Inventors: Masayoshi Kuroda, Masataka Oda
