Patent number: 11962972Abstract: To enhance a sound image localization effect and to ensure a good viewing state in which an image or video and audio have a sense of unity. Provided is a display in which an image is displayed in a display surface, a rear cover disposed on a rear side of the display, a first speaker disposed between the display and the rear cover, and a second speaker disposed between the display and the rear cover and positioned higher than the first speaker. The second speaker outputs audio according to operation of a piezoelectric element, and has a higher audio output band than the first speaker. This enables a user to feel as if the audio is being output from the display being viewed, which enhances the sound image localization effect and ensures a good viewing state in which an image or video and audio have a sense of unity.Type: GrantFiled: November 21, 2019Date of Patent: April 16, 2024Assignee: SONY GROUP CORPORATIONInventors: Masahiro Takahashi, Tatsuya Sakata, Tetsuya Shiroishi, Shigemi Oguchi, Kazumasa Okamoto, Ryosuke Nakajima

Patent number: 8248464Abstract: An endoscope signal processor to which an endoscope having an image pickup device is detachably connected has a phase-locked loop circuit in which a phase comparator compares a phase of a variable clock with that of a reference clock output from the image pickup device to generate a variable clock phase-synchronized with the reference clock. The processor includes a gate section opened or closed to input of the reference clock to the phase comparator, an operation control signal generation section which generates an operation control signal for setting the phase-locked loop circuit in a closed loop operable state during intermittent periods, and a sync timing setting section which synchronizes a timing of starting the generation of the operation control signal with a timing of input of the variable clock to the phase comparator at least within a predetermined time period shorter than the cycle of the variable clock.Type: GrantFiled: December 14, 2006Date of Patent: August 21, 2012Assignee: Olympus Medical Systems Corp.Inventor: Kazumasa Takahashi
