Abstract:
A handheld optical information reading device is provided which comprises a housing, a grip arranged on the housing, an image capture device, an illuminator, an illumination controller, an imaging controller, an image processor, and a reader. The image capture device captures an image including a symbol. The illuminator includes lighting devices around the periphery of an optical axis of the image capture device. The illumination controller controls the illuminator to selectively successively light up the lighting devices based on a predetermined order whereby irradiating a symbol with light in different illumination directions with respect to the optical axis. The imaging controller controls the image capture device to capture images of the symbol every when the lighting devices are selectively successively lighted up. The image processor creates an outline image of the symbol based on the captured images. The reader reads the symbol based on the created outline image.
