摘要： An electronic optical zoom system (100) includes a first lens assembly (101) and a second lens assembly (102). The first lens assembly (101) and the second lens assembly (102) may be adjacently disposed or concentrically disposed. The first lens assembly (101) and second lens assembly (102), in one embodiment, have different magnification configurations. An image sensor (103) captures electronic images of a subject (109). Optical zoom capability is achieved by an alterable electronic optical device (851), such as a switchable mirror (105). The alterable electronic optical device (851) selectively redirects received light between a first optical path (107) from a reflective surface (106) to a second optical path (117) from the alterable electronic optical device (851) depending upon the state of the alterable electronic optical device (851). The electronic optical zoom system (100) thereby provides optical zoom capabilities in a compact package without the need for physically moving lens assemblies.

The system (200) includes a light source (201) capable of projecting lights having different light wavelength spectrum upon the sample object (203).

摘要： Disclosed are methods and devices for solid state electronically switched optical shutters of cameras and other devices. The disclosed non-mechanical camera shutter includes an electronically controlled material that provides optical density variation, to transition the shutter from being open to being closed. The layer of electronically controlled material is configured to change from substantially to transparent to substantially opaque, without scattering, by changing the state of the material. The transmittance period is the period of time that the layer changes transmittance from approximately 100% to approximately 0%. Electronic circuitry is in communication with a timing control module that is configured to provide a signal output to a transparent conductive layer proximal to the layer of electronically controlled material to initiate a change in its transmissivity. The described electronically switched optical component would add little or no additional bulk to a small camera.

摘要： A circuit for use in an image sensor as well as an image sensing system using the circuit are set forth. The circuit comprises a memory device having a non-volatile memory cell, a control gate, a drain and a source. The circuit also employs a photosensitive semiconductor device that is positioned for exposure to electromagnetic radiation from an image. A pixel control circuit is connected to these components to direct the memory device and the photosensitive semiconductor device to a plurality of controlled modes. The controlled modes may include an erase mode and an exposure mode. In the erase mode, at least a portion of an electric charge is removed from the non-volatile memory cell to place the memory device in an initialized state. In the exposure mode, the non-volatile memory cell is charged at least partially in response to a voltage at a terminal of the photosensitive semiconductor device. The voltage at the terminal of the photosensitive semiconductor device corresponds to exposure of the photosensitive semiconductor device to the electromagnetic radiation from the image. The pixel control circuit may also direct the memory device and the photosensitive semiconductor device to further modes including a read mode and a data retention mode. In the read mode, current flow between the source and drain of the memory device is detected as an indicator of the charge on the non-volatile memory cell. In the data retention mode, the charge on the non-volatile memory cell of the memory device that was acquired during the exposure mode is maintained notwithstanding further exposure of the photosensitive semiconductor device to the electromagnetic radiation from the image. The circuit, and one or more peripheral support circuits, may be implemented in a monolithic substrate using, for example, conventional CMOS manufacturing processes.
