  • Patent number: 9252176
    Abstract: A solid state imaging device includes an array of active pixels and an infrared cut filter formed over the sensor. Optionally, a slot in the infrared cut filter allows infrared illumination to reach the sensor to be detected by pixels covered by a visually opaque filter and surrounded by pixels of special types that limit charge leakage and enable high dynamic range sensing of infrared illumination. A ratio of average infrared signal to average brightness indicates an amount of infrared illumination reaching the imaging device.

  • Publication number: 20150350512
    Abstract: Systems, methods, and computer readable media for the use of a metric whose value is especially sensitive to the information lost when an image's pixels are clipped are disclosed. The metric may be used as an image's score, where higher values are indicative of lost highlight information (more clipped pixels). One use of the disclosed metric would be to determine when the use of high dynamic range (HDR) techniques are appropriate. The disclosed metric may also be used to bias a scene's exposure value (EV) such as to a lower or underexposed value (EV?) so that the scene may be captured with no more than an acceptable number of clipped pixels.

  • Publication number: 20150350513
    Abstract: Systems, methods, and computer readable media to capture and process high dynamic range (HDR) images when appropriate for a scene are disclosed. When appropriate, multiple images at a single—slightly underexposed—exposure value are captured (making a constant bracket HDR capture sequence) and local tone mapping (LTM) applied to each image. Local tone map and histogram information can be used to generate a noise-amplification mask which can be used during fusion operations. Images obtained and fused in the disclosed manner provide high dynamic range with improved noise and de-ghosting characteristics.

  • Patent number: 9152292
    Abstract: A user interface that includes a catalog area, a collage mock-up area, and a mode select interface control operable to select an operational state of the user interface is displayed. Thumbnails of respective images are shown in the catalog area. A layout of a subset of the images is presented in the collage mock-up area. In response to the receipt of a user input gesture and a determination that the user interface is in a first operational state, a first action type is performed based on the type of the received user input gesture and the object type of the target object. In response to the receipt of the user input gesture and a determination that the user interface is in a second operational state, a second action type is performed based on the type of the received user input gesture and the object type of the target object.

  • Patent number: 9113089
    Abstract: Methods to generate, and devices to use, an adaptive tone curve generation operation are disclosed. Tone curves so generated have been found to produce stable tone mapping in a wide range of operational environments, including during multi-exposure fused images (e.g., during high dynamic range image fusion). In general, techniques are disclosed that use a content-load histogram in combination with image capture device noise information to adaptively bound a tone curve's slope and, therefore, the resulting tone curve. As used here, a content-load histogram is a histogram that captures spatial, color or other information carried by an image's pixels at various gray levels.

  • Patent number: 9030575
    Abstract: A novel chromaticity space is disclosed that may be used as a framework to implement an auto-white balance solution or other color image processing solutions that take advantage of the particular properties of the novel chromaticity space. The chromaticity space may be defined by using a series of mathematical transformations having parameters that are optimized to adapt to specific sensors' spectral sensitivities. The unique properties of the novel chromaticity space provide a conscious white point constraining strategy with clear physical meaning. In this chromaticity space, the ranges of possible white points under different kinds of lighting conditions can be defined by polygons. Because of the physical meaning the chromaticity space, the projection that is needed to bring an initially “out-of-bounds” white point back into the polygon also carries physical meaning, making the definition of projection behavior and its consequences conceptually clean and predictable.

  • Patent number: 9007484
    Abstract: Methods, devices and computer readable media for implementing novel dominant color alleviation techniques for color balancing are described. The techniques take advantage of unique properties of 2D image data histograms accumulated in a chromaticity space, along with other factors such as estimated scene lux and knowledge of plausible scene illuminant white point values within the chromaticity space. The accumulated 2D image data histograms may be refined and “trimmed,” such that the resultant image data passed to an auto white balance solution has much less influence from the dominant colors in the image, even those that overlap the plausible scene illuminant color region. The described techniques provide for white point estimates that are much less prone to dominant color failures.

  • Patent number: 8780225
    Abstract: Methods, devices and computer readable media for implementing a “selective gray world” approach for color balancing are described. The disclosed techniques involve the use of noise-optimized selection criteria and, more specifically, in some embodiments, the interpolation between corresponding values in noise-optimized weighting tables when calculating white balance gains. Estimated scene lux levels may provide a valuable indicator of expected scene noise levels. The image processing techniques described herein may be executed by an image capture device or a general purpose processor (e.g., personal computer) executing a user-level software application. The described color balancing techniques may be implemented by dedicated or general purpose hardware, general application software, or a combination of software and hardware in a computer system.

  • Patent number: 8682108
    Abstract: A system and a method are disclosed that determine placement of a background image on a canvas and area for placement of foreground images. A system and method include receiving data indicative of an informative zone of a background image and computing an estimated foreground area on a canvas for each candidate placement of the background image on the canvas. The estimated foreground area is computed based on the data indicative of the informative zone and the number of images to be used as foreground images and does not include the informative zone. One of the candidate placements is determined as a selected background placement based on the computed values of estimated foreground area. A composite image can be generated from the background image positioned on the canvas according to the selected background placement and foreground images positioned outside of the informative zone.
