Publication number: 20220108427Abstract: Example embodiments include a method and an electronic device for detecting and removing artifacts/degradations in media. Embodiments may detect artifacts and/or degradations in the media based on tag information indicating at least one artifact included in the media. The detection may be triggered automatically or manually. Embodiments may generate artifact/quality tag information associated with the media to indicate artifacts and/or degradations present in the media, and may store the artifact/quality tag information as metadata and/or in a database. Embodiments may identify, based on the artifact/quality tag information associated with the media, at least one artificial intelligence (AI)-based media processing model to be applied to the media to enhance the media. The at least one AI-based media processing model may be configured to enhance at least one artifact detected in the media. Embodiments may enhance the media by applying the at least one AI-based media enhancement model to the media.Type: ApplicationFiled: December 14, 2021Publication date: April 7, 2022Applicant: SAMSUNG ELECTRONICS CO., LTD.Inventors: Beomsu KIM, Balvinder SINGH, Alok Shankarlal SHUKLA, Jisung YOO, Narasimha Gopalakrishna PAI, Prajit Sivasankaran NAIR, Raj Narayana GADDE, Sungsoo CHOI, Sirish Kumar PASUPULETI

Patent number: 11146762Abstract: Methods and systems for reconstructing a high frame rate high resolution video in a Bayer domain, when an imaging device is set in a Flexible Sub-Sampled Readout (FSR) mode are described. A method provides the FSR mode, which utilizes a multiparty FSR mechanism to spatially and temporally sample the full frame Bayer data. The multi parity FSR utilizes a zigzag sampling that assists reconstruction of motion compensated artifact free high frame rate high resolution video with full frame size. The method includes reconstructing the high frame rate high resolution video using the plurality of parity fields generated. The reconstruction is based on a FSR reconstruction mechanism that can be a pre-Image Signal Processor (ISP) FSR reconstruction or a post-ISP FSP reconstruction based on bandwidth capacity of an ISP used by the imaging device.Type: GrantFiled: January 19, 2017Date of Patent: October 12, 2021Assignee: Samsung Electronics Co., Ltd.Inventors: Alok Shankarlal Shukla, Sathish Chalasani, Narasimha Gopalakrishna Pai, Pyo-jae Kim, Jin-hee Na, Abhishek Somani, Venkatesh Ambati

Publication number: 20150086127Abstract: A method and an image capturing device configured to generate a defocused image from a reference image and one or more of focal bracketed images to provide an artificially defocused blurred image. The artificially defocused blurred image is a fusion image composed by processing the reference image and one or more of focal bracketed images to provide a clear foreground with gradual blurred background based on a created depth map. The method is time efficient as it provides faster processing on a captured and down sampled reference image and one or more captured down sampled aligned focal bracketed images. The depth map created using region based segmentation reduces a misclassification at a time of classifying foreground-background and misclassification of pixels to provide fast, robust artificial blurring of background in the captured reference image.Type: ApplicationFiled: May 9, 2014Publication date: March 26, 2015Applicant: Samsung Electronics Co., LtdInventors: K.
