Detailed description of the invention
[0022] Disclosed herein are imaging systems and methods for use in spatially constrained locations. The disclosed imaging systems and methods have utility in a range of applications. For example, endoscopic camera systems, particularly those associated with medical procedures, often impose stringent space requirements. Other applications include consumer electronics where greater performance is insisted on for smaller devices.
[0023] Disclosed herein is an image sensor with an asymmetric configuration. The image sensors include photosensitive pixel arrays for capturing images formed thereon, supporting electronics, and connectors connecting the pixel arrays to the supporting electronics. For each of its pixels, the pixel array generates an electrical signal corresponding to the amount of light incident thereon. The supporting electronics may include functions such as readout control, gain control, timing control, and / or amplificatio...

An imaging system for use in a space-constrained location includes an image sensor for capturing images, wherein the image sensor has (a) a first rectangular area including an array of pixels and connecting circuitry communicatively coupled to the array of pixels, and (b) A second rectangular area having only a shared side with the first rectangular area and including supporting electronics for pixel array control and signal acquisition, wherein the supporting electronics are communicatively coupled to the connecting circuit. An imaging method for use in a spatially constrained location includes (a) forming an image of a scene on an array of pixels of an image sensor contained within a first rectangular region having a first side, and (b ) communicating electrical signals between the pixel array and a supporting electronic device that is located on the image sensor and is contained within a second rectangular area that shares only one area with the first rectangular area. side.
Description
technical field [0001] The demand for sophisticated camera systems delivering high performance is increasing with the increasing use of imaging systems in a wide variety of applications. Such applications are found in areas such as consumer electronics, machine vision, automotive, and medical diagnostics and procedures. Background technique [0002] Medical endoscopy to inspect the interior of the human body presents an example of challenging requirements for the size of the camera system. The camera system, including at least the image sensor, optics, and electronics, must be suitable within the area to be inspected. Preferably, the camera system should be sufficiently refined so that there is room in the desired direction to pass the camera through to inspect the environment. Furthermore, the camera system is often directed to the region of interest via a channel such as an artery which itself assumes size constraints. At the same time, the imaging capabilities and perf...
