Patent number: 5495343Abstract: An image signal recording and reproducing system of this invention is arranged to record an image signal on a recording medium and to reproduce a recorded image signal from the recording medium. The system is provided with a first recording mode for recording an image signal for one picture having a first resolution on n recording tracks (n: positive integer) of the recording medium and a second recording mode for recording an image signal for one picture having a second resolution higher than the first resolution on m recording tracks (m: integer greater than n) of the recording medium. If an image signal recorded on the basis of the second recording mode is to be reproduced from the recording medium on which image signals are recorded in either one of the first and second recording modes, an arbitrary portion of an image corresponding to the image signal reproduced from the recording medium is extracted and outputted.Type: GrantFiled: August 4, 1994Date of Patent: February 27, 1996Assignee: Canon Kabushiki KaishaInventor: Shigeo Ogura

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

Patent number: 5493335Abstract: An electronic camera is adapted for processing images of different resolution to provide a user selectable image record size. A buffer memory is provided for storing color image pixels from a sensor as baseband signals corresponding to at least one image. A timing controller responsive to a resolution mode switch controls the order in which color image pixels are selected for storage in both vertical and horizontal directions. The order selected by the resolution switch includes a full resolution mode, and at least one reduced resolution mode in which the color image pixels are subsampled such that each chrominance image pixel is selected to be spatially adjacent to a selected luminance image pixel. Additionally, the buffer memory can store a burst of low resolution images.Type: GrantFiled: June 30, 1993Date of Patent: February 20, 1996Assignee: Eastman Kodak CompanyInventors: Kenneth A.

Patent number: 5481303Abstract: An electronic still camera indicates the available capacity of a recording medium and the number of frames remaining that may be photographed, as well as warning by stages in at least two forms, based on the available capacity of the recording medium. The electronic still camera includes a photo lens, mirror, CCD, signal executing circuit, A/D converter, buffer memory, compression circuit, CPU, memory card, and indicator device. A CPU reads in the gross capacity and the written-on portion from a memory card and calculates the available capacity. When the available capacity becomes small, the indicator device that indicates the available capacity or the number of frames remaining that can be photographed begins to flash the display slowly on and off. When the available capacity grows even smaller and is almost gone, the display flashes rapidly on and off. In this way, the photographer can easily detect how many more frames he or she may photograph on the memory card.Type: GrantFiled: May 20, 1994Date of Patent: January 2, 1996Assignee: Nikon CorporationInventor: Ryo Uehara
