Abstract: Demosaicking optimizations are provided for still and/or moving image (e.g., video) processes that efficiently generate viewable images. A demosaicking process selects a direction before performing interpolation in order to avoid interpolation across edges and also to minimize color artifacts. The direction to be selected is based on a direction similarity measurement. A digital capture device can includes a system that processes the image data by performing interpolation based on the direction similarity measurement(s) for color difference spaces. The images created based on the directional similarities demonstrate performance gains in peak signal to noise ratio (PSNR).

Abstract: A method includes performing a single pass filtering that integrates a first pass demosaicking and a second pass demosaicking into a single pass operation. The method can include interpolating in a vertical direction as well as interpolating in a horizontal direction. The vertical interpolation can be compared with the horizontal interpolation and one interpolation can be selected. The method can include comparing a vector with a plurality of neighbor vectors and selecting the direction with the smallest vector difference. A digital camera is provided that includes at least one data store for storing a plurality of video images, and a host system that processes the video images by performing a single pass filtering that integrates a first pass demosaicking and a second pass demosaicking into a single simple pass (SP) filtering operation. The host system compares a vertical interpolation with a horizontal interpolation and selects one interpolation, in another exemplary non-limiting embodiment.
