Converting a data stream format in an apparatus for and method of reading targets by image capture

摘要

An apparatus and method read a target by capturing return light from the target with a solid-state monochrome imager operative for generating an output data stream in a monochrome format having a plurality of slots containing pixel data indicative of an image of the target, and with a color controller for receiving the output data stream in a color format different from the monochrome format. A converter circuit converts the monochrome format into the color format and includes an input formatter for formatting the output data stream to have additional slots, a buffer for receiving auxiliary pixel data related to the image of the target, and an output formatter for inserting the auxiliary pixel data from the buffer into the additional slots and for processing both the pixel data and the auxiliary pixel data to enhance the reading of the target.

主权项

1. An apparatus for reading a target by image capture, comprising:
a housing; a window supported by the housing; a solid-state monochrome imager supported by the housing and having an array of light sensors looking at a field of view that extends through the window to the target, and operative for capturing return light from the target to be read, and for generating an output data stream in a monochrome format having a plurality of slots containing pixel data indicative of an image of the target; a controller for controlling the monochrome imager and having a color video input for receiving the output data stream in a color format different from the monochrome format; and a converter circuit for formatting the output data stream to have additional slots to convert the monochrome format into the color format, for receiving auxiliary pixel data related to the image of the target, for inserting the auxiliary pixel data into the additional slots, and for processing both the pixel data and the auxiliary pixel data to enhance the reading of the target.
