Patent number: 10970827Abstract: An image processor includes: an image sensor outputting a short exposure image and a long exposure image; a sensor controller that, when brightness of the subject changes, controls first exposure sensitivity to cause the short exposure image to have first brightness and controls second exposure sensitivity to cause the long exposure image to have second brightness; a motion blending ratio calculator calculating a motion blending ratio based on a motion amount of the subject; a motion-adapted image synthesizer generating a motion-adapted image by synthesizing a corrected short exposure image and the long exposure image based on the motion blending ratio; and an HDR image synthesizer generating an HDR image by synthesizing the motion-adapted image and the short exposure image together. When the subject becomes darker, the sensor controller controls the first and second exposure sensitivities to cause the first sensor gain to be at most the second sensor gain.Type: GrantFiled: October 4, 2019Date of Patent: April 6, 2021Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Tomokuni Iijima, Nobutoshi Fujinami, Shigeru Furumiya

Patent number: 8558875Abstract: The video signal processing device has a parallax detection unit for detecting the parallax between a right-eye video signal and a left-eye video signal and outputting the detected parallax as a parallax detection signal. The video signal processing device has an encoding noise detection unit for detecting an encoding noise generated by encoding processing, outputting an encoding noise detection signal corrected by using a detection result of the detected encoding noise based on the parallax detection signal. The video signal processing device has an encoding noise removing unit for performing at least one of reducing the encoding noise by filtering processing using the encoding noise detection signal, and reducing, based on the parallax detection signal, the encoding noise by replacing the data of a noise generating pixel in the right-eye video signal and the left-eye video signal.Type: GrantFiled: September 28, 2009Date of Patent: October 15, 2013Assignee: Panasonic CorporationInventors: Hideki Morino, Ryuichi Shibutani, Haruko Terai, Nobutoshi Fujinami

Publication number: 20120249757Abstract: An object is to provide a stereoscopic video display device having improved convenience which simultaneously displays a plurality of stereoscopic video footages on one screen, thereby allowing a viewer to simultaneously view the plurality of stereoscopic video footages. The stereoscopic video display device includes: a display panel 230 in which a screen for displaying a plurality of stereoscopic video footages is arranged; and a video control section 240 that controls the display of the plurality of stereoscopic video footages. Each stereoscopic video footage includes right-eye video and left-eye video each having parallax with respect to the other. The video control section 240 simultaneously displays the stereoscopic video footages in given positions on the screen, periodically displays the right-eye video and the left-eye video of each stereoscopic video footage, and synchronizes the timing at which the right-eye video and the left-eye video of each stereoscopic video footage are displayed.Type: ApplicationFiled: February 10, 2011Publication date: October 4, 2012Applicant: PANASONIC CORPORATIONInventor: Nobutoshi Fujinami
