Patent number: 9854180Abstract: In one embodiment, a camera includes an image sensor within a camera housing that converts light entering the camera housing through an optical filter into digital image data. The optical filter can have a variable opacity. A processor in communication with the image sensor identifies operation settings for the optical filter and adjusts an opacity level of the optical filter over an exposure period in accordance with the operation settings for the optical filter. In addition, the processor modifies values of the digital image data based at least on the operation settings for the optical filter.Type: GrantFiled: May 25, 2016Date of Patent: December 26, 2017Assignee: RED.COM, LLCInventors: Anthony Wayne Davis, Robert Rose, Thomas Graeme Nattress, Peter Jarred Land, James H. Jannard

Patent number: 9699482Abstract: An image encoder includes an input for a high dynamic range input image (M_HDR); an image grading unit arranged to allow a human color grader to specify a color mapping from a representation (HDR_REP) of the high dynamic range input image defined according to a predefined accuracy, to a low dynamic range image (Im_LDR) by a human-determined color mapping algorithm. The image encoder is configured to output data specifying the color mapping (Fi(MP_DH)). Further, the image encoder includes an automatic grading unit configured to derive a second low dynamic range image (GT_IDR) by applying an automatic color mapping algorithm to one of the high dynamic range input image (M_HDR) and the low dynamic range image (Im_LDR).Type: GrantFiled: February 7, 2014Date of Patent: July 4, 2017Assignee: KONINKLIJKE PHILIPS N.V.Inventor: Mark Jozef Willem Mertens
