Patent number: 6683999Abstract: In a data communication apparatus for encoding information data by using a predetermined encoding method, encoded information data is transmitted isochronously with a predetermined communication cycle when the encoding method corresponds to a decoding method at an object node apparatus and non-encoded information data is transmitted asynchronously with the communication cycle when the encoding method does not correspond to the decoding method at the object node apparatus. It is therefore possible to perform an encoding process for the information data to be transmitted, in accordance with a decoding performance at the object node apparatus, to improve a communication efficiency, and to reduce a capacity of a memory used for communications.Type: GrantFiled: July 15, 2002Date of Patent: January 27, 2004Assignee: Canon Kabushiki KaishaInventors: Masamichi Ito, Susumu Kozuki

Patent number: 6069994Abstract: An apparatus is disclosed which is arranged to record a video signal in first areas respectively provided in a multiplicity of tracks on a recording medium and also a digital still-image signal in second areas which are respectively separated from the first areas. In the apparatus, while the digital still-image signal is being recorded in the second areas, the video signal is always recorded in the first areas, whereby it is possible to prevent occurrence of an uncomfortable phenomenon, such as formation of a scene devoid of a substantial image, during reproduction from the first areas. In addition, an analog still-image signal, representative of an image identical to an image represented by the digital still-image signal recorded in the second areas, is repeatedly recorded in the first areas during a predetermined time duration, whereby it is possible to facilitate search of a still-image signal recorded in the second areas.Type: GrantFiled: April 16, 1996Date of Patent: May 30, 2000Assignee: Canon Kabushiki KaishaInventors: Susumu Kozuki, Isao Harigaya, Taizou Hori

Patent number: 6031569Abstract: In order to display a high resolution still image by using a single image sensor type image sensing apparatus employing a single relatively low resolution CCD, an image of an identical object is taken four times in short time intervals. Each time the image sensing operation is carried on, it is controlled that an imaging position on a photo-sensing surface of the CCD is shifted by one pixel. Color signals of the plurality of color components which are obtained as above are stored in a predetermined areas in an image memory by each color component. After four image sensing operations are completed, the color signals are read from the image memory, and the final color signals or brightness signals are generated based on the read color signals, and displayed on a display.Type: GrantFiled: December 3, 1996Date of Patent: February 29, 2000Assignee: Canon Kabushiki KaishaInventors: Kousuke Nobuoka, Susumu Kozuki

Patent number: 5495342Abstract: A video signal recording apparatus for recording of a still-image signal on a recording medium can be set to an interval recording mode for recording a still-image signal at intervals of a predetermined time interval. First time data relative to a recording time according to the amount of information of the still-image signal for one picture is compared with second time data relative to the predetermined time interval. If the first time data is greater than the second time data, a notice to that effect is given for the purpose of preventing an operation error. In addition, a similar advantage can be achieved by displaying the first time data. Also, if the first time data is greater than the second time data, the apparatus is disabled from being set to the interval recording mode.Type: GrantFiled: April 19, 1995Date of Patent: February 27, 1996Assignee: Canon Kabushiki KaishaInventors: Isao Harigaya, Susumu Kozuki
