Publication number: 20240040079Abstract: The present technology is to enable a transmitter device to read appropriate device information (EDID) from a receiver device with a reduced burden on the user. A memory unit that stores first device information and second device information, and a communication unit that communicates with an external device are included. The control unit determines to cause the external device to read the second device information, on the basis of reception of a rewrite signal for the first device information from the external device. It is possible to cause the external device (a transmitter device) to read appropriate device information (EDID) from a receiver device (a reception device) with a reduced burden on the user, and thus, user-friendliness can be increased.Type: ApplicationFiled: October 13, 2023Publication date: February 1, 2024Applicant: Sony Group CorporationInventors: Masahiko Nakahama, Nobutaka Yamamoto

Patent number: 10215663Abstract: The present invention addresses the problem of the inability to sufficiently reduce manufacturing cost for specifying a faulty section of an optical fiber. The device according to the present invention is a device connected to an optical fiber into which light reflection elements that reflect a fixed amount of light are inserted, said device being provided with a transmission means for transmitting light to the optical fiber and stopping the transmission, a measurement means for measuring the intensity of the reflection light reflected by the light reflection elements, a time measurement means for measuring the time from the stopping of the transmission of the light by the transmission means to the reduction of the intensity of the reflection light measured by the measurement means to a prescribed value or less, a distance measurement means for calculating a distance corresponding to the time measured by the time measurement means, and an output means for outputting a signal indicating the distance.Type: GrantFiled: June 17, 2016Date of Patent: February 26, 2019Assignee: NEC CORPORATIONInventor: Masahiko Nakahama

Patent number: 8767125Abstract: A video display device, a video output device, and a video system are provided, each of which has a user-interface having high usability in menu operation so that false operation may be prevented, and a menu-screen-display control method is provided. The menu-screen-display control method includes: determination process of determining which device, of a video display device and one or more video output devices connected to the video display device, is an object of operation through a menu screen displayed on the video display device; and prohibition process of setting a non-object device into a menu-operation-prohibited mode, the non-object device being a device other than an operation object device which is determined to be the object of operation through the menu screen under display.Type: GrantFiled: February 19, 2010Date of Patent: July 1, 2014Assignee: Sony CorporationInventors: Yosuke Kozono, Masahiko Nakahama

Publication number: 20130208024Abstract: Provided are an image processing method, an image processing device, an image processing circuit, and an image display unit that allow occurrence of a crosstalk to be reduced. When an image signal Din is input, the image signal Din is converted into an image signal D?in with a narrower dynamic range based on a lookup table (53A) on a dynamic range control section (51). At this time, the dynamic range of the image signal D?in is set up to an extent of avoiding saturation in an overdrive correction. Subsequently, an image signal Dout is generated by performing the overdrive correction for the image signal D?in using the lookup table (53A) on an overdrive control section (52).Type: ApplicationFiled: April 28, 2011Publication date: August 15, 2013Applicant: SONY CORPORATIONInventors: Kyoichiro Oda, Koichi Katagawa, Masayuki Takahashi, Atsushi Ito, Masahiko Nakahama

Patent number: 8190786Abstract: A data receiver as a sink for receiving a transmission content from a source performing a content transmission process, the data receiver includes a memory for storing device information; and a control unit for changing a setup of a hot plug state in which the source may be detected, as a process of notifying the source whether the data stored in the memory can be obtained or not. The control unit is arranged to set the hot plug state as a setup indicative of being in a state where the data stored in the memory is permitted to be obtained, in a selection state where the source is selected as a contents input device, and control is performed to maintain a setup showing that the hot plug state is in a state where data stored in the memory is permitted to be obtained, in a case where the source is changed to a non-selection state from a selection state in which the source is selected as the contents input device.Type: GrantFiled: April 22, 2008Date of Patent: May 29, 2012Assignee: Sony CorporationInventor: Masahiko Nakahama
