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.
