Embodiment Construction

[0042] phase integration

[0043] According to one aspect of the present invention, there is provided a wide dynamic range sensor element or array that accurately captures high and low brightness images using phase domain integration techniques. The sensor element of the present invention is not limited by the dynamic range performance exhibited by prior art solid state pixel structures, and thus can capture the entire range of electromagnetic radiation to provide a high quality output image.

[0044] Figure 7A A schematic diagram of the response of a sensor element was built for use of the technique of the present invention. The extended dynamic range of the sensor element is sufficient to enable it to respond to illuminating light with a pixel response over the entire range of electromagnetic radiation intensities. Thus, the sensor elements are able to capture sufficient charge in the darkest parts while avoiding saturation effects in bright parts of the captured image....

Abstract

A high dynamic range sensitive sensor element or array is provided which uses phase domain integration techniques to accurately capture high and low intensity images. The sensor element of the present invention is not limited by dynamic range characteristics exhibited by prior art solid-state pixel structures and is thus capable of capturing a full range of electromagnetic radiation to provide a high quality output 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 photometry and transmission. Background technique [0002] Photography is an imaging process that relies on the action of light. Light is the commonly used condition, and its frequency in electromagnetic radiation is in the range visible to the human eye. The light pattern reflected or emitted from the object is recorded by an image sensor after a certain time of exposure. Image sensors can be chemical in nature, such as photographic negatives; they can also be solid-state, such as CCD and CMOS image sensors used in digital cameras and video cameras. [0003] A digital camera has a series of lenses that focus light to create an image of the scene. But instead of focusing the light on a film like a conventional camera, the light is focused on an image sensor, which converts the electromagnetic r...
