Systems and methods are provided for generating high-dynamic range images. In particular, a signal-to-noise (SNR) ratio objective associated with an imaging platform configured to capture one or more images of a region of interest using an image sensor having a first portion and a second portion can be determined. The SNR objective can specify a desired SNR response as a function of a brightness of the region of interest. A first integration time and a second integration time can then be determined based at least in part on the SNR objective. Data indicative of a plurality of image frames can then be obtained. Each image frame is captured by exposing the first portion of the image sensor for the first integration time and exposing the second portion of the image sensor for the second integration time.

Generating high-dynamic range images using multiple filters

Systems and methods are provided for generating high-dynamic range images. In particular, a signal-to-noise (SNR) ratio objective associated with an imaging platform configured to capture one or more images of a region of interest can be determined. The SNR objective can specify a desired signal-to-noise ratio behavior as a function of a brightness of the region of interest. An exposure profile associated with the imaging platform can then be determined based at least in part on the SNR objective. Data indicative of a plurality of image frames, each depicting at least a portion of the region of interest, can then be obtained. The plurality of image frames being captured by the imaging platform in accordance with the exposure profile.

Generating high-dynamic range images using varying exposures

Apparatus and method of forming and displaying high dynamic range (HDR) images for various purposes including the testing of image capture devices, such as cameras. A display device has a display panel carrying a plurality of rendered images formed from image data of a scene. At least one light source is used to illuminate the rendered images on the display panel. When the rendered images are aligned with one another and illuminated by the light source, the rendered images are capable of forming a display image having a dynamic range higher than those of the rendered images.

Apparatus and method for forming and displaying high dynamic range (HDR) images

A method of reducing noise in an image including steps for obtaining a first value for a target pixel, obtaining a respective second value for each neighboring pixel surrounding the target pixel, identifying a spread for the second values, comparing the spread to a threshold value, and, if the spread if below the threshold value, calculating a new value using the second values, and replacing the first value with the new value.
