Patent number: 10872440Abstract: An image signal processing device receives image signals from source devices and outputs image signals via a plurality of communication paths. The image signal processing device includes a plurality of compression circuits, a transmission circuit and a path/compression-rate setting circuit. The plurality of compression circuits compress image signals to be transmitted via the plurality of communication paths. The transmission circuit outputs the image signals compressed. The path/compression-rate setting circuit, based on each data amount of the image signals received, determines a communication path for transmitting a part or the whole of each of the image signal, and sets a common compression rate for all of the plurality of compression circuits. The path/compression-rate setting circuit divides an image signal having a relatively large data amount, and assigns a part of the divided image signal to a communication path for transmitting an image signal having a relatively small data amount.Type: GrantFiled: July 2, 2018Date of Patent: December 22, 2020Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Masaru Sekizawa, Takaaki Abe, Ryoji Okubo, Kazuma Tani, Iori Hayashi

Patent number: 10091477Abstract: The projection image display apparatus includes a display element that emits image light generated by modulating light from a light source based, a pixel-shifter that shifts a pixel of a projected image by changing an optical path of the image light, a resampling circuit, a motion-interpolation image processing circuit, and a pixel-shift controller. The resampling circuit generates a plurality of sub-frame image signals having a resolution of the display element, by resampling an image signal having a resolution of the projected image. The motion-interpolation image processing circuit provides a motion-interpolation image process to the sub-frame image signals. The pixel-shift controller receives the sub-frame image signals having undergone the motion-interpolation image process.Type: GrantFiled: June 15, 2016Date of Patent: October 2, 2018Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Akiyoshi Yamaguchi, Masutaka Inoue, Takaaki Gyoten, Takaaki Abe, Ryoji Okubo, Kazuma Tani

Patent number: 9823466Abstract: The optical path changing device of the present disclosure includes an optical member having a parallel plate face for changing an optical path, and first, second, and third actuators. The first, the second, and the third actuators are connected with the optical member at first, second, and third vertices of a triangle imaginarily drawn on a plane parallel to the parallel plate face of the optical member. The first, the second, and the third actuators drive the optical member forward and backward in a normal direction of the parallel plate face at the first, the second, and the third vertices serving as points of load. The optical member has a center of gravity within the triangle when seen from the normal direction.Type: GrantFiled: June 11, 2016Date of Patent: November 21, 2017Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Takaaki Abe, Masutaka Inoue, Takaaki Gyoten, Ryoji Okubo, Akiyoshi Yamaguchi, Kazuma Tani
