Patent number: 6084632Abstract: Video signals are recorded in such a manner that prints having a high picture quality can be obtained while not interfering with playback of images in the form of a movie. A CCD is controlled in such a manner that exposure is performed at a shutter speed of 1/250 of a second one time in exposures performed a plurality of times in succession and at a shutter speed of 1/60 of a second at other times. The video signal outputted by the CCD is applied to a combining circuit via a CDS, AGC and signal processing circuit for an image sensing system. A PI signal generating circuit outputs a PI signal, which represents inhibition of printing, in the case where exposure is carried out at the shutter speed of 1/60 of a second, and the combining circuit superposes the PI signal upon the video signal, which has been obtained by exposure at the shutter speed of 1/60 of a second, in the vertical blanking interval of this video signal.Type: GrantFiled: August 10, 1998Date of Patent: July 4, 2000Assignee: Fuji Photo Film, Ltd.Inventors: Masafumi Inuiya, Michitoshi Takayama, Kazuya Oda, Takeshi Misawa, Yasuko Sonoda

Patent number: 5982984Abstract: In a case frame image possessing an amount of data greater than a predetermined amount is recorded on a magnetic tape using a multiplicity of tracks, on which tracks the data has been recorded is made clear. Image data composed of 1,400,000 pixels, which is four times that of the conventional number of 350,000 pixels, is obtained. Since the image data has an amount of data that is four times that in a frame image when photography is performed using the conventional 350,000-pixel CCD, the image data is recorded in a video recording area one frame at a time on ten tracks per frame, for a total of 40 tracks. Auxiliary-area recording data representing on which tracks the recorded image data has been recorded and the manner in which the recorded image has been partitioned is recorded in an auxiliary recording area. One frame of a still picture is produced after reference is made to the auxiliary-area recording data that has been recorded in the auxiliary recording area.Type: GrantFiled: January 31, 1996Date of Patent: November 9, 1999Assignee: Fuji Photo Film Co., Ltd.Inventor: Masafumi Inuiya

Patent number: 5668914Abstract: Both a sharp print image and a natural reproduced move image can be obtained from a signal recorded on a recording medium. A recording signal, read from the recording medium, is converted into digital data and is delayed by one field. Data representing the current image in the n-th field and data representing an image in the (n-1)-th field one field ahead of the current image, are applied to a subtracting circuit, to extract a component representing moving image portions. An interpolated image for making movement correction is created from the extracted component representing the moving image portions by an interpolating circuit. Data representing the interpolated image and the data representing the current image in the n-th field are synthesized by a synthesizing circuit, to output composite data as data representing an image which has been subjected to movement correction.Type: GrantFiled: June 22, 1995Date of Patent: September 16, 1997Assignee: Fuji Photo Film Co., Ltd.Inventors: Masafumi Inuiya, Kazuyuki Masugane
