摘要： An electronic camera for producing an output image of a scene from a captured image signal includes a first imaging stage comprising a first image sensor for generating a first sensor output and a first lens for forming a first image of the scene on the first image sensor, and a second imaging stage comprising a second image sensor for generating a second sensor output and a second lens for forming a second image of the scene on the second image sensor, where the lenses have different focal lengths. A processing stage uses the sensor output from one of the imaging stages as the captured image signal and uses the images from both imaging stages to generate a range map identifying distances to the different portions of the scene.

The Laplacian second-order and the gradient values are combined to define a value for each image pixel such that there are sets of values with each value corresponding to a classifier and for selecting a preferred orientation from a group of orientations for the interpolation based upon the classifier. Finally, in response to the preferred orientation and the measured digital image for estimating the luminance or chrominance value for each corresponding image pixel.

An arrangement is disclosed for averaging existing green values for green photosite locations which includes structure for storing the digitized image signal, defining green classifiers based upon adding the Laplacian second-order values, and the gradient values to define a classsifier, and modifying a measured green pixel based upon adjacent pixel classifiers. The apparatus further includes structure for determining which classifiers represent a pixel neighborhood of slowly changing scene detail, and replacing the measured green values for a green photosite location with an average of surrounding predicted green pixels as a function of the number of classifiers which are below a predetermined value.
