Abstract
An illuminating light assembly in a healthcare scanner illuminates a target to be electro-optically read with visible illumination light of a first color, e.g., white, during a day mode, and illuminates the target with visible illumination light of a second, more psychologically soothing, color, e.g., red or amber, during a night mode. A solid-state imager captures an image of the illuminated target in either mode, and a controller processes the captured image in either mode.
Claims19
An arrangement for differently illuminating targets to be electro-optically read in different day and night modes of operation, comprising:
- an illuminating light assembly for illuminating a target with visible illumination light of a first color during the day mode, and for illuminating the target with visible illumination light of a second color during the night mode that is different from the first color during the day mode;
- a solid-state imager for capturing an image of the illuminated target in either mode;
- and
- a controller for controlling the imager and the illuminating light assembly, and for processing the captured image in either mode.
A method of differently illuminating targets to be electro-optically read in different day and night modes of operation, comprising:
- illuminating a target with visible illumination light of a first color during the day mode;
- illuminating the target with visible illumination light of a second color during the night mode that is different from the first color during the day mode;
- capturing an image of the illuminated target in either mode;
- and
- processing the captured image in either mode.
