Patent number: 11895427Abstract: A method for generating a composite image comprises: detecting a color temperature of a background image; acquiring from a camera through an image signal processor, ISP, performing white balance correction of acquired image data, an image including a foreground region including face of a user; and detecting a color temperature of the foreground region. Responsive to the color temperature for the foreground region differing from that of the background image by more than a threshold amount, a color temperature for white balance correction of a subsequently acquired image is set which causes skin pixels within the foreground region of the subsequently acquired image to have a color temperature closer to the color temperature for the background image. Pixel values of the foreground region are combined with pixel values of the background image corresponding to a background region of the acquired image to provide the composite image.Type: GrantFiled: August 25, 2021Date of Patent: February 6, 2024Inventors: Razvan Condorovici, Andra Stan, Cosmin Stan

Publication number: 20240031676Abstract: A method for reducing camera motion blur comprises, before acquiring an image frame for a video stream, a camera measurement unit measuring data related to a camera module motion during a time window; determining camera module motion based on the measured data and predicting a camera motion blur during acquisition of the image frame based at least on the determined camera module motion and the lens projection model; determining whether the predicted camera motion blur exceeds a threshold; in response to determining that the predicted camera motion blur exceeds the threshold, determining a reduction of the provisional exposure time determined to acquire the image frame so that the predicted camera motion blur reaches the threshold, determining whether a corresponding increase in the provisional gain determined to acquire the image frame is below a maximum gain value, adjusting the provisional exposure time and gain, and acquiring the image frame.Type: ApplicationFiled: October 5, 2023Publication date: January 25, 2024Inventors: Razvan Condorovici, Bogdan Petcu, Piotr Stec

Publication number: 20230327897Abstract: A method at a first participant's client conferencing system in a videoconference comprises receiving, from a second client conferencing system, at least one first video frame of a first video signal including an image of the second participant looking at a third participant, and first metadata associated with the first video frame and including an identity of the third participant. The image of the second participant is modified in the first video frame so that the first video frame is displayed on a first area of the client conferencing system with the second participant looking at a second area of the first display configured for displaying a second video signal of the third participant identified by the first metadata.Type: ApplicationFiled: June 14, 2023Publication date: October 12, 2023Applicant: FotoNation LimitedInventors: Razvan Condorovici, Andra Stan

Patent number: 10769435Abstract: A method of image processing within an image acquisition device. In one embodiment an image including one or more face regions is acquired and one or more iris regions are identified within the one or more face regions. The one or more iris regions are analyzed to identify any iris region containing an iris pattern that poses a risk of biometrically identifying a subject within the image. Responsive to identifying any such iris region, a respective substitute iris region, containing an iris pattern distinct from the identified iris pattern to avoid identifying the subject within the image, is determined and the identified iris region is replaced with the substitute iris region in the original image.Type: GrantFiled: October 17, 2019Date of Patent: September 8, 2020Assignee: FotoNation LimitedInventors: Ilariu Raducan, Ruxandra Vranceanu, Razvan Condorovici, Cosmin Stan, Peter Corcoran

Publication number: 20170186138Abstract: A method of image processing within an image acquisition device comprises acquiring an image including one or more face regions and identifying one or more iris regions within the one or more face regions. The one or more iris regions are analyzed to identify any iris region comprising an iris pattern of sufficient quality to pose a risk of biometrically identifying a subject within the image. Responsive to identifying any such iris region, a respective substitute iris region comprising an iris pattern sufficiently distinct from the identified iris pattern to avoid identifying the subject within the image is determined and the identified iris region is replaced with the substitute iris region in the original image.Type: ApplicationFiled: March 27, 2015Publication date: June 29, 2017Inventors: Ilariu RADUCAN, Ruxandra VRANCEANU, Razvan CONDOROVICI, Cosmin STAN, Peter CORCORAN
