Abstract

There is described a device having a two dimensional imager. The device having a two dimensional image sensor can be a hand held device. Imaging optics can be provided for focusing light reflected from a target onto the two dimensional imager. A two dimensional image sensor can be a color image sensor adapting the hand held device for use in obtaining a color image having color imaging data. Color imaging data obtained can be subject to processing.

Claims

1. A hand held device comprising:

a two dimensional imager;

wherein said two dimensional imager includes a Bayer pattern filter, the Bayer pattern filter adapting said hand held device for use in obtaining two dimensional color images;

imaging optics for focusing light reflected from a target onto said two dimensional imager;

a processor communicatively coupled with said two dimensional imager;

an actuator for manually initiating image capture, the hand held device being adapted so that in response to said actuator being actuated by a user, said hand held device obtains a color image for processing, said color image for processing including color imaging data; and

wherein said hand held device is further adapted so that said processing includes (a) processing said color image according to a first process, wherein a result of said first process indicates whether a bar code symbol is represented in said color image; and

(b) subsequently determining whether a signature is represented in said color image, wherein said determining step (b) is executed conditionally on the condition that a result of said processing step (a) indicates that a bar code symbol is not represented in said color image.

2. The hand held device of claim 1, wherein said processing step (a) includes locating of a representation of a bar code symbol.

3. The hand held device of claim 1, wherein said processing step (a) includes striking of scan lines.

4. The hand held device of claim 1, wherein said hand held device is adapted to crop a represented signature if said hand held device determines that a signature is represented in said color image.

5. The hand held device of claim 1, wherein said hand held device is adapted to compress a represented signature if said hand held device determines that a signature is represented in said color image.

6. The hand held device of claim 1, wherein said hand held device is adapted to crop and compress a represented signature if said hand held device determines that a signature is represented in said color image.

7. The hand held device of claim 1, wherein said hand held device is adapted to crop and compress a represented signature if said hand held device determines that a signature is represented in said color image, and wherein said hand held device is in communication with remote network resources for providing signature verification.

8. The hand held device of claim 1, wherein said held device further includes a signature block for use in capturing a signature with use of a stylus.

9. The hand held device of claim 1, wherein said hand held device includes a display and a keypad.

10. The hand held device of claim 1, wherein said hand held device includes a top having disposed thereon a display and a keypad, and wherein said hand held device includes an input/output unit provided by a wireless interface.
