摘要： A camera and method which selectively applies image content adjustments to elements contained in the image material. By way of example, the method involves registration of user touch screen input and determination of the arbitrary extent of a specific element in the captured image material at the location at which touch input was registered. Once selected, the element can be highlighted on the display, and additional user input may be optionally input to control what type of adjustment is to be applied. Then the element within the captured image material is processed to apply automatic, or user-selected, adjustments to the content of said element in relation to the remainder of the captured image. The adjustments to the image element may comprise any conventional forms of image editing, such as saturation, white balance, exposure, sizing, noise reduction, sharpening, blurring, deleting and so forth.

摘要： A high dynamic range (HDR) compression method and apparatus modeled after the heat equation describing temperature changes in a thin plate. This approach allows combining high dynamic range compression together with noise reduction in a single process, to be performed within the same iteration of the heat equation. Noise reduction is of particular concern while performing HDR compression because brightening of dark areas during high dynamic range compression has the potential to increase noise levels. Performing image processing techniques in combination according to the invention provides enhanced results while lowering the overall processing overhead. This innovation extends the heat equation analogy by adding anisotropic diffusion as an additional term, which allows joint operation of HDR and NR and mitigates noise enhancement within HDR compression during shadow enhancement.

摘要： A method for high dynamic range compression uses a modified cumulative histogram as a compression curve. This curve is computed from the cumulative histogram of the image with constraints that the local derivative on the curve does not exceed a certain limit. The limit is fixed along the curve or the limit is variable, taking into account noise characteristics at various pixel values. To provide appropriate detail preservation, a smoothing filter is used to separate the image into an illumination image, referred to as a base image, and a detail image, and the compression curve is applied to the base image only. The compression method provides high dynamic range compression of the image while preserving the global contrast perception. Conventional global algorithms for high dynamic range compression are not capable of achieving this result. The proposed high dynamic range compression method also minimizes noise amplification while lightening the dark areas during image compression.

摘要： A method of evaluating halo artifacts is described herein. The method utilizes a pattern of color patches, a color space and color difference metrics to analyze color changes which correlate to the amount of halo. The pattern of color patches is utilized in the CIE L*a*b* color space to determine an area of patch unaffected by halo of the pattern of color patches. After the area of patch unaffected by halo is determined, a Reference Value is computed by averaging the CIE L*a*b* color for the area of patch unaffected by halo. Then an Artifact Value is calculated either by averaging the CIE L*a*b* color for the area outside the area of patch unaffected by halo but before the margin or by averaging the CIE L*a*b* color on the edge of the patch. Once these values are determined, the halo quantity is calculated.

摘要： A system and method for performing a depth estimation procedure utilizing defocused pillbox images includes a camera device with a sensor device for capturing pillbox blur images of a photographic target. The camera utilizes a depth estimator for performing a Gaussianization procedure that transforms the pillbox blur images into corresponding Gaussian blur images. The Gaussianization procedure is performed by convolving the pillbox blur images with a Gaussianization kernel to generate the corresponding Gaussian blur images. The depth estimator then utilizes the Gaussian blur images for effectively performing the depth estimation procedure.
