Patent number: 10868533Abstract: Electrodes and regions of top plate opposed to electrodes constitute switches that have capacitances varying when the regions of top plate are depressed from top plate toward electrodes. Depression detection circuit calculates the capacitance change amounts of switches indicating changes of the capacitances from a reference value. Depression detection circuit calculates the maximum value and sum of the capacitance change amounts of switches. When the capacitance change amount of at least one switch exceeds threshold and a situation in which the ratio of the maximum value to the sum is equal to or greater than threshold has lasted for the number of repetitions in, depression detection circuit determines that the switch having the maximum value of the capacitance change amount is in a depressed state.Type: GrantFiled: July 26, 2019Date of Patent: December 15, 2020Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Masami Yamamoto, Yukinobu Tokoro, Shohei Kawagoe, Kojiro Kawasaki, Tadayoshi Okuda, Yosuke Shiota

Patent number: 7711249Abstract: When a digital broadcast is decoded and then re-encoded and digitally recorded, detailed program information contained in the original digital broadcast and information such as age-based viewer control information or parental control information may be lost. This problem is solved by providing a digital tuner to demodulate the digital broadcast signal and output the MPEG-TS, a demultiplexer to demultiplex the MPEG-TS into the component packet streams, an AV decoder to decode the demultiplexed AV data packets, and an AV encoder to re-encode the demultiplexed AV data packets into AV data packets for recording. A control microprocessor reads, reconstructs, and sends the PSI or SI packets demultiplexed by the demultiplexer to save the viewer control information to the system multiplexer. The system multiplexer multiplexes the PSI or SI packets with the re-encoded AV data packets, and the multiplexed stream is then written to the recording medium.Type: GrantFiled: November 10, 2003Date of Patent: May 4, 2010Assignee: Panasonic CorporationInventors: Kojiro Kawasaki, Hiroyuki Kondo, Masahiro Horie

Patent number: 7313283Abstract: A video frame is input to a spectrum analyzer, which transforms the frame from a spatial domain into a frequency domain. A resolution determiner analyzes the output of the spectrum analyzer, thereby selecting a resolution appropriate for the video frame. Then, a resolution converter converts a resolution of the video frame into the resolution selected by the resolution determiner. Thereafter, the video frame is subjected to a coding process by block divider, DCT transformer, quantizer and variable-length coder so as to be output as a coded bit stream. By coding the input video frame at a resolution corresponding to the high-frequency component in the frame, a video of higher quality can be obtained with the bit rate reduced.Type: GrantFiled: June 8, 2005Date of Patent: December 25, 2007Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Satoshi Kondo, Kojiro Kawasaki, Hideki Fukuda, Kazuhiko Nakamura, Shiro Iwasaki
