Patent number: 12114081Abstract: Imaging devices and methods for generating a color image from a low-light scene. A method incudes filtering light from the low-light scene to produce a first light channel having filtered light filtered by a first filter and a second light channel having unfiltered light. The method includes producing a first information channel and a second information channel. The first information channel includes first brightness information corresponding to the first light channel and the second information channel includes second brightness information corresponding to the second light channel. The method includes receiving the first information channel and the second information channel and assigning the first brightness information to a first color channel. The method includes assigning the second brightness information to second color channel and processing the first color channel and the second color channel to produce a full-color image stream. The method includes outputting the full-color image stream.Type: GrantFiled: February 18, 2022Date of Patent: October 8, 2024Assignee: Chromatra, LLCInventors: Peter W. J.

Patent number: 11070773Abstract: Full-color images of low-light scenes are generated by the systems and methods described herein using only two light channels. An array of photosensitive pixels includes two sets of pixels, the first sensitive only to light associated with a first light channel, the second only to light associated with a second light channel. Thus the first set of pixels generate a first set of electrical signals in response to incident light within the first light channel, and the second set of pixels generate a second set of electrical signals in response to incident light within the second light channel. An image processor receives the first and second sets of electrical signals and generates a full-color image of the scene by processing only signals generated by the first and second sets of pixels.Type: GrantFiled: June 26, 2019Date of Patent: July 20, 2021Assignee: Chromatra, LLCInventors: Peter W.

Patent number: 10893181Abstract: An integrated color imaging system has a housing with an objective lens, photocathode and image intensifier. The image intensifier has radiation sensitive sensors and a phosphor screen. A rotatable first filter wheel is located between the objective lens and the photocathode. The first filter wheel can include first channels selectively positionable in an optical path of the image, and at least one of the first channels is clear and unfiltered. A rotatable second filter wheel can be located inside the housing between the phosphor screen and an eyepiece lens of the housing. The second filter wheel can include second channels selectively positionable in the optical path between the phosphor screen and the eyepiece lens, and at least one of the second channels is clear and unfiltered. The clear and unfiltered channels of the first and second filter wheels can be selectively aligned and held in the optical path.Type: GrantFiled: January 23, 2020Date of Patent: January 12, 2021Assignee: Chromatra, LLCInventors: Peter W.
