Patent number: 11887286Abstract: An image that enables proper object recognition is generated. An image processing device includes an image processing unit that processes an image. The image processing unit included in this image processing device corrects the level of a pixel constituting the image. That is, the image processing unit corrects the level of a target pixel constituting the image on the basis of a low-frequency component in a peripheral image of a pixel constituting the target image. Here, the peripheral image is made up of a plurality of pixels that includes the target pixel and is located around the target pixel.Type: GrantFiled: August 2, 2019Date of Patent: January 30, 2024Assignee: SONY SEMICONDUCTOR SOLUTIONS CORPORATIONInventor: Yoshiaki Tatae

Patent number: 11363954Abstract: A device and method for fluorescent imaging may include an imaging unit including a fluorescent camera with an optical detector that is configured to acquire a fluorescent image of a fluorescing sample, the image including raw pixel values. A user interface may display an image formed from display image pixels derived from the raw image pixels. A distance sensor may measure a distance to the fluorescing sample. A distance between the optical detector and fluorescing sample may be determined from the measured distance. A processing unit may obtain a gain value, match the determined distance to a distance value associated a respective gain range, and impose limits of the gain values range onto the gain value, to determine a limited gain value. The limited gain value may be applied to the raw image pixels, thereby deriving display image pixels.Type: GrantFiled: October 3, 2018Date of Patent: June 21, 2022Assignee: Visionsense LTD.Inventors: Nadav Horesh, Alex Chanin, Ofer Braude
