Demosaicking: Color Filter Array Interpolation in Single-Chip Digital Cameras
Digital cameras have become popular and many people are choosing to take their pictures with digital cameras instead of film cameras. When a digital image is recorded, the camera needs to perform a significant amount of processing to provide the user a viewable image. This processing includes white balance adjustment, gamma correction, compression and more (reference “Color Image Processing Pip...
متن کاملColor filter array demosaicking: new method and performance measures
Single-sensor digital cameras capture imagery by covering the sensor surface with a color filter array (CFA) such that each sensor pixel only samples one of three primary color values. To render a full-color image, an interpolation process, commonly referred to as CFA demosaicking, is required to estimate the other two missing color values at each pixel. In this paper, we present two contributi...
متن کاملColor Filter Array Image Analysis for Joint Denoising and Demosaicking
A single-chip image sensor used in almost all consumer and in some professional-grade digital cameras today is affixed with an alternating pattern of spectrally shifted (in the electromagnetic wavelength sense) color filters to each pixel location. The arrangement of color filters, which are typically the canonical color triples (i.e. red, green, blue), is called color filter array (or CFA) [1,...
متن کاملSecond-Generation Color Filter Array and Demosaicking Designs
Recent developments in spatio-spectral sampling theory for color imaging devices show that the choice of color filter array largely determines the spatial resolution of color images achievable by subsequent processing schemes such as demosaicking and image denoising. This paper highlights the cost-effectiveness of a new breed of color filter array patterns based on this sampling theory by detai...
متن کاملHybrid color filter array demosaicking for effective artifact suppression
Color filter array (CFA) demosaicking is an essential process for restoring full-color images from incomplete color samples acquired by single-sensor digital cameras. We present two main contributions to CFA demosaicking. First, we analyze the causes of two main types of CFA demosaicking artifacts and examine the schemes that are effective in suppressing them, respectively. Second, by combining...
