Abstract
There is set forth an apparatus for capturing image data. In one embodiment, an apparatus is operative for capture of a first frame of image data and a second frame of image data. In one embodiment, an apparatus is operative for processing the first frame of image data and the second frame of image data.
Claims20
An optical reader, comprising:
- an image sensor operative to capture frames comprising decodable indicia;
- a first light source operative to project light;
- a second light source operative to project light;
- wherein the optical reader is operative to project light with the first light source and capture a first frame comprising a decodable indicia via the image sensor;
- wherein the optical reader is operative to process the captured first frame to determine whether the captured first frame is saturated, thereby indicating excessive illumination;
- and
- wherein the optical reader is operative to project light with the second light source and capture a second frame comprising the decodable indicia via the image sensor.

An apparatus, comprising:
- a first image sensor operative to generate a first image signal, the first image sensor having a first image axis extending in a first direction, wherein a portion of the first image signal is representative of decodable indicia;
- a first light source operative to project light;
- a second image sensor operative to generate a second image signal, the second image sensor having a second image axis extending in a second direction that is different than the first direction, wherein a portion of the second image signal is representative of decodable indicia;
- a second light source operative to project light;
- a first converter operative to convert image signals generated by the first image sensor into first image data;
- a second converter operative to convert image signals generated by the second image sensor into second image data;
- a random access memory;
- an integrated circuit, the integrated circuit comprising:
- a first frame grabber for receiving the first image data and transmitting the first image data to the random access memory;
- and
- a second frame grabber for receiving the second image data and transmitting the second image data to the random access memory;
- wherein the apparatus is operative to:
- project light with the first light source;
- process a first frame of the first image data generated while the first light source is projecting light to determine whether the first frame is saturated, thereby indicating excessive illumination, wherein the first frame comprises a decodable indicia;
- project light with the second light source;
- and
- capture a second frame of the second image data generated while the second light source is projecting light, wherein the second frame comprises the decodable indicia.

An optical reader, comprising:
- a first image sensor operative to generate first image data, the first image sensor having a first image axis extending in a first direction, wherein a portion of the first image signal is representative of decodable indicia;
- a second image sensor operative to generate second image data, the second image sensor having a second image axis in a vertical plane with the first image axis and extending in a second direction that is different than the first direction, wherein a portion of the second image signal is representative of decodable indicia:
- a first light source operative to project light;
- a second light source operative to project light;
- wherein the reader is operative to:
- project with the first light source;
- while projecting light with the first light source, generate first image data with the first image sensor, wherein the first image data comprises data representative of a decodable indicia;
- process a first frame of the first image data to determine whether the first frame is saturated, thereby indicating excessive illumination;
- project light with the second light source;
- and
- while projecting light with the second light source, generate second image data with the second image sensor, wherein the second image data comprises data representative of the decodable indicia.
