Abstract
A method and system for additively, manually sequentially or manually in parallel, selecting multiple points or regions of interest in the analog or digital viewfinder of a photo or video camera with automatic controls like auto-focusing, auto-metering and auto white-balancing. Points or regions capable of being selected, within a grid of elements comprising a camera's evaluative matrix and represented to the user in a viewfinder or other display, may be hard-coded (pre-defined, selectable regions) or any point, pixel, or group of pixels. Data from the selected regions is used to simultaneously, dynamically adjust focus related parameters, light metering and white balancing of the camera and is tied into these features. Point selection may be via touch screen or by holding down a lock button. The selected points or regions may be applied to focus and aperture related adjustments or for any other camera function related to measurement of the scene.
