Embodiment Construction

[0032] According to one aspect of the present invention, a solid state pixel structure or pixel array includes integrated exposure controls disposed in the pixel structure and / or pixel array. Exposure control included within the pixel structure and / or array enables optimal exposure in real time. By measuring the response of the pixel structure to the received electromagnetic radiation. And using this response information, combined with knowledge about the capabilities of the pixel structure and the threshold value of the photometric measurements, to determine when the pixel structure is functioning optimally for optimal exposure.

[0033] In one embodiment, each solid state pixel structure is capable of photometric measurements. This measurement characterizes the pixel structure's response to electromagnetic radiation. By incorporating photometric capabilities within the solid-state pixel structure, pixel exposure is monitored and tightly controlled during image capture. Th...

Abstract

A solid-state pixel structure or pixel array includes integrated exposure control provided within the pixel structure and / or pixel array. Including exposure control within the pixel structure and / or array allows optimal exposure to be achieved in real time. Optimal exposure is achieved by measuring the response of pixel structures to received electromagnetic radiation, and using the response information, in conjunction with knowledge regarding the pixel structure capabilities and photometric thresholds, to determine when the pixel structure is operating optimally. Tight control of the exposure of the pixel structure to the electromagnetic radiation allows the pixel structure to operate optimally in order to provide an optimal captured image.

Description

technical field [0001] The present invention relates generally to the field of electronic imaging, and more particularly to a method and apparatus for enhancing image capture using photometric measurement and reporting. Background technique [0002] Photography is the process of imaging by the action of light. Light is commonly used, and its frequency in electromagnetic radiation is in the range visible to the human eye. The pattern of light reflected or emitted from the object is recorded by an image sensor over a period of exposure. Image sensors can be chemical in nature, such as photographic film, or solid-state, such as CCD and CMOS image sensors used in digital cameras and video cameras. [0003] Digital cameras have a series of lenses that focus light to create an image of a scene. But instead of focusing light on a film like a conventional camera, it focuses light on a solid-state image sensor that converts the light's electromagnetic radiation into electrical cha...
