1. A barcode reader, comprising:
- a lens for focusing an image of a barcode onto a two-dimensional photo sensor array;
an image capture system configured to receive image capture parameters and capturing multiple frames of image data in sequence, each captured with image capture settings determined in accordance with the image capture parameters, wherein at least one of the multiple frames of image data is captured with an image capture setting set to distinct value different from the value of the image capture setting for at least one other frame of image data;
a processor configured to select an image data record from the multiple frames of image data and decode the selected image data record.

Abstract
A barcode reader may perform image processing functions to generate distinct image data records from the frame of image data of a barcode, select an image data record from the distinct image data records and decode the selected image data record. Each image data record may be generated by applying a distinct image processing function to the frame of image data. The barcode reader may capture multiple frames of image data in sequence based on image capture parameters. At least one of the multiple frames of image data may be captured with a distinct parameter value. The image capture parameters may include an exposure setting, a gain setting, a resolution setting, and/or an illumination setting.

11. A barcode reader, comprising:
-
a camera system configured to capture a sequence of frames of image data, each comprising an image of a barcode within a field of view of the camera system; an illumination system including a plurality of illumination sub-systems for illuminating the field of view of the camera system; and a processor coupled to the camera system and configured to generate image capture parameter values for each frame of the sequence of frames of image data and provide the image capture parameter values to the camera system, wherein the image capture parameter values define a quantity of frames of image data to be captured in the sequence and, for each frame, image capture settings, wherein an image capture setting for at least one frame of image data is distinct from an image capture setting for at least one other frame of image data within the sequence. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A method for reading a barcode, the method comprising:
-
generating image capture parameter values for each frame of image data within a sequence of frames of image data, wherein the image capture parameter values define a quantity of frames of image data to be captured in the sequence and image capture settings for each frame of image data in the sequence, wherein an image capture setting for at least one frame of image data is distinct from the image capture setting for at least one other frame of image data within the sequence; providing the image capture parameter values to a camera system; capturing a sequence of frames of image data in accordance with the image capture parameter values; storing the sequence of frames of image data in a buffer memory; selecting a frame of image data from the sequence of frames and decoding the selected frame of image data. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30)
