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.

摘要： A system (200) and method (800) for determining whether a sample object (203) has a color that is within a predetermined range is provided. The system (200) includes a light source (201) capable of projecting lights having different light wavelength spectrum upon the sample object (203). A controller (222) causes the light source (201) to project a first light wavelength spectrum upon the sample object (203), then another, then another, and so forth. While each light is projecting upon the object, a monochromatic image capture device (202) captures an image having luminous intensity information. The luminous intensity information, or a subset thereof selected by an image selection tool (232) is then compared to the statistical range, which is derived from a plurality of images taken of a reference object (403).

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 floating gate semiconductor device having a floating gate, 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 floating gate semiconductor 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 floating gate to place the floating gate semiconductor device in an initialized state. In the exposure mode, the floating gate 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 floating gate semiconductor 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 floating gate semiconductor device is detected as an indicator of the charge on the floating gate. In the data retention mode, the charge on the floating gate of the floating gate semiconductor 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.
