Patent number: 9674481Abstract: A first video signal having a first frame rate optionally settable is generated by an image pickup device, and the first video signal is memorized in a memory and outputted from the memory. A write control device controls the write of the first video signal with respect to the memory, and a read control device controls the read of the video signal with respect to the memory. The write control device writes respective first frame data constituting the first video signal in the memory in each cycle determined by the first frame rate of the first video signal. The read control device reads the first frame data as a second video signal. The second video signal is formed from sequentially arranging the first frame data in a partially duplicating manner in a standard video signal having a standard frame rate based on a determined arrangement rule.Type: GrantFiled: May 4, 2015Date of Patent: June 6, 2017Assignee: Panasonic Intellectual Property Management Co., Ltd.Inventors: Shinji Takemoto, Shoichi Fuse, Kazumasa Motoda, Akiyuki Noda

Patent number: 8976272Abstract: In an imaging apparatus, unevenness in brightness in screen due to flash is eliminated and video with secured continuity as a moving image can be obtained. In the imaging apparatus (1), signals of fields affected by flash among video signals acquired by imaging are treated with adding or adding and averaging to equalize effects of flash which appear unevenly on a screen.Type: GrantFiled: February 24, 2010Date of Patent: March 10, 2015Assignee: Panasonic Intellectual Property Management Co., Ltd.Inventors: Katsuyuki Fukui, Ryoji Asada, Yasushi Fukushima, Tadayuki Inoue, Kazumasa Motoda, Takamasa Yokoyama

Patent number: 8823842Abstract: The line buffer stores an input image after a change is made to the stored line position of each horizontal segment. The stored-line position memory unit stores the stored line position of each horizontal segment in the line buffer. The vertical interpolator performs vertical interpolation on each of outputs of the line buffer based on the differences between the vertical interpolation line positions and the stored line positions. Thus, the number of lines needed for vertical interpolation to be stored in the line buffer can be reduced.Type: GrantFiled: October 11, 2012Date of Patent: September 2, 2014Assignee: Panasonic CorporationInventor: Kazumasa Motoda

Patent number: 7061531Abstract: An imaging device uses a solid state imaging element, during multi-field accumulation to prevent shading and oscillatory phenomena such as repeated black and white patterns. A signal is supplied from a timing signal generation circuit to switches, and controls the ON/OFF operation. During the H period of the signal, the switch is closed, and the output value of an amplifier is input to a capacitor. During the L period of the signal, the switch is opened, and the average value of the output of the amplifier is maintained in the capacitor. During the H period, the switch is open, while during the L period, the switch is in the ON state. At this time, the level of the capacitor C2 and the output of the amplifier are input to an amplifier, and their difference is amplified and supplied to a capacitor C3 via the switch.Type: GrantFiled: June 22, 2001Date of Patent: June 13, 2006Assignee: Matsushita Electric Industrial Co., LtdInventors: Hiromasa Funakoshi, Ryoji Asada, Kazumasa Motoda
