An imaging system substantially simultaneously acquires z-depth and brightness data from first sensors, and acquires higher resolution RGB data from second sensors, and fuses data from the first and second sensors to model an RGBZ image whose resolution can be as high as resolution of the second sensors. Time correlation of captured data from first and second sensors is associated with captured image data, which permits arbitrary mapping between the two data sources, ranging from 1:many to many:1. Preferably pixels from each set of sensors that image the same target point are mapped. Many z-depth sensor settings may be used to create a static environmental model. Non-correlative and correlative filtering is carried out, and up-sampling to increase z-resolution occurs, from which a three-dimensional model is constructed using registration and calibration data.

A method for resolution enhancement of a still-image made by a digital imaging device. The method allows the use of high-aperture-ratio sensing arrays that produce resolution-enhancement, independent of the angle of view. Resolution-enhancement is achieved using a multiple-exposure technique of a sub-pixel overtap in conjunction with a whole-pixel shift. The method suppresses color-aliasing in a multiple-exposure native-resolution mode and enables the use of a single camera for single-exposure and multiple-exposure modes.

An electronic imaging sensor. The sensor includes an array of photo-sensing pixel elements for producing image frames. Each pixel element defines a photo-sensing region and includes a charge collecting element for collecting electrical charges produced in the photo-sensing region, and a charge storage element for the storage of the collected charges. The sensor also includes charge sensing elements for sensing the collected charges, and charge-to-signal conversion elements. The sensor also includes timing elements for controlling the pixel circuits to produce image frames at a predetermined normal frame rate based on a master clock signal (such as 12 MHz or 10 MHz). This predetermined normal frame rate which may be a video rate (such as about 30 frames per second or 25 frames per second) establishes a normal maximum per frame exposure time. The sensor includes circuits (based on prior art techniques) for adjusting the per frame exposure time (normally based on ambient light levels) and novel frame rate adjusting features for reducing the frame rate below the predetermined normal frame rate, without changing the master clock signal, to permit per frame exposure times above the normal maximum exposure time. This permits good exposures even in very low light levels. (There is an obvious compromise of lowering of the frame rate in conditions of very low light levels, but in most cases this is preferable to inadequate exposure.) These adjustments can be automatic or manual.
