Embodiment Construction

[0013] The detailed description provided below in conjunction with the accompanying drawings is intended as a description of the present example and is not intended to represent the only forms of making or utilizing the present example. The description sets forth the functionality of the example and the sequence of operations used to construct and operate the example. However, the same or equivalent functions and sequences can be implemented by different examples.

[0014] As mentioned above, although technology is available to allow people to annotate electronic copies of documents on the screen (e.g., using keyboard input or a special pen sensed by the display), many people still prefer to annotate manually (i.e., using pen / pencil by hand). Note) printed document. This manual (or handwritten) annotation may be referred to as "inking". There are many reasons for this preference for manual annotation, and these include the ease of the annotation process, where the user simpl...

Abstract

A system is described which comprises an electronic display device, an annotation capture module and a camera. The annotation capture module is configured to trigger a change in an image displayed onthe electronic display device responsive to a capture trigger and the camera is configured to capture one or more images of the electronic display device in response to the capture trigger and / or a trigger received from the annotation capture module. The annotation capture module is further arranged to identify any manual annotations made by a user on the electronic display device by analyzing theimages of the electronic display device captured by the camera, wherein at least one of the images was captured after the change in the image displayed.

Description

Background technique [0001] Handwritten annotation of a document or drawing is a very natural action, and even though it is possible to annotate on the screen in some software applications that use keyboard input, and on some tablet computing devices that use a special pen sensed by the tablet, many people still Choose handwritten note paper printouts because they are lightweight, low cost, and easy to carry and pass on to others. However, one faces difficulties in merging hand annotations back into the electronic version of the document. [0002] The embodiments described below are not limited to implementations that address any or all of the disadvantages of known handwritten annotation methods. Contents of the invention [0003] The following presents a simplified summary of the disclosure in order to provide the reader with a basic understanding. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intende...
