## Abstract

A workstation captures images of illuminated symbols with a solid-state imager. In an embodiment, the workstation includes a removable camera module in the workstation away from the imager. The camera module captures a secondary image through a window. The captured image of the illuminated symbol and the captured secondary image are independently processed.

## Claims

### Claim 1

A barcode reader comprising:
a housing having a window located in a plane, the window facing a scan zone configured to receive a product presented by an operator;
an illuminating assembly supported by the housing, and configured to illuminate, during illumination time periods, a symbol associated with the product in the scan zone, wherein the illumination time periods are spaced apart by time intervals;
an imager supported by the housing and configured to capture a first image of the illuminated symbol, the imager having an array of image sensors configured to receive return illumination light from the illuminated symbol passing through the window to the imager;
a camera mounted in the housing separate from the imager, and configured to capture a second image associated with a video through the window; and
a controller configured to:
coordinate timing of the imager and the camera; and
independently process the first image and the second image.

### Claim 2 (depends on 1)

The barcode reader of claim 1, wherein the controller is configured to coordinate the timing of the imager and the camera by controlling the imager to capture the first image during one of the illumination periods and controlling the camera to capture the second image during one of the time intervals.

### Claim 3 (depends on 1)

The barcode reader of claim 1, further comprising an optical assembly configured to split a field of view of the imager into a plurality of intersecting subfields of view.

### Claim 4 (depends on 1)

The barcode reader of claim 1, wherein:
the controller is configured to control the illuminating assembly to illuminate the symbol with illumination light during the illumination time periods;
no illumination light is generated by the illuminating assembly during the time intervals; and
the controller is configured to control the camera to capture the second image only during the time intervals with no illumination light.

### Claim 5 (depends on 4)

The barcode reader of claim 4, wherein the controller is configured to control the camera to capture the second image only during the time intervals after a predetermined number of the illumination time periods have elapsed.

### Claim 6 (depends on 4)

The barcode reader of claim 4, wherein the camera is configured to capture the second image using only ambient light.

### Claim 7 (depends on 1)

The barcode reader of claim 1, further comprising a manual actuator configured to, when engaged, deactivate the illuminating assembly and concomitantly actuate the camera to capture the second image.

### Claim 8 (depends on 3)

The barcode reader of claim 3, wherein the camera has a first angle of view greater than a second angle of view of individual ones of the subfields of view.

### Claim 9 (depends on 1)

The barcode reader of claim 1, wherein the housing includes a removable housing portion, and the camera is configured to be mounted inside the housing after removal of the housing portion.

### Claim 10 (depends on 1)

The barcode reader of claim 1, wherein the camera is mounted on a printed circuit board, and a transmitter on the printed circuit board is configured to transmit the second image to a remote host.
