    摘要: Systems and methods of optical code reading include production of image data by a color image sensor array (102) and processing of the image data to decode an optical code (112). In one configuration, the color image sensor array includes first and second sets of sensor pixels (204, 206, and/or 208) sensitive to light having wavelengths within, respectively, first and second wavelength bands, reflected light is focused by an optical system (104) to form an image of an optical code on the color image sensor array, first and second sets of image data representing light intensity levels sensed by, respectively, the first and second sets of sensor pixels are produced, and the first set of image data is processed to determine whether the second set of image data is to be used in combination with the first set of image data to decode the optical code.

    摘要: There is provided an integrated semiconductor source-detector matrix (10) in which solid state photonic diodes (12a-12i) are configured as LEDs, disposed on a substrate and coupled to electronic circuits so that the diodes can be individually driven to emit light to detect light as may be desired. Providing an integrated matrix (10) of light source and light sensor units disposed in close proximity results in each unit having nearly coextensive fields of view and illumination (157). Apparatus, such as bar code and optical readers utilizing such a matrix are shown, and are insensitive to the diffusion and laminate effects. In alternate embodiments the matrix (10) is coupled to remote sensors (94) or another similar matrix to provide optical communication and inter-change devices having high bandwidth.
