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 display module (100) with reduced power consumption uses a control circuit (110) to reset row and column display drivers (130, 140) and turn off a portion of the display (150) when the display module (100) is in a partial display mode. The partial display mode allows a reduction in the driving voltages for the display which in turn reduces the power needed by the bias voltage divider (120) which produces the driving voltages. The display module (100) with reduced power consumption is applicable to both LCD and non-LCD technologies, such as electroluminescence or cathode ray tube, using a multiplex or scanning methodology.
