The following disclosure relates generally to scanners, and more particularly to handheld scanning devices.
Optical scanners capture and digitize images of documents. Most scanners are relatively large devices that are used to scan documents a full page at a time. An example of such a scanner is discussed in U.S. Pat. No. 6,678,075.
Recently, smaller scanners have been introduced. Typically, these smaller scanners are used to scan less than a full page of a document. For example, they can be used to scan sentences or phrases from a document. The data obtained from the scanning process is typically immediately transferred to a personal computer via a permanent wired connection for processing and/or storage.
However, these scanners generally do not store a large amount of data, and, therefore, a user may need to transfer data to another storage device, such as a computer, before obtaining everything they may want or need. In this regard, the user may not be near their computer and may not be able to transfer data out of the scanner in order to clear room in the scanner's storage for subsequently scanned data.
Additionally, a handheld scanner may be one of a number of portable devices carried by a user. For example, a user may carry a cell phone, a scanner, a portable storage device, an mp3 player, and so on. Despite their relatively small size, carrying a number of devices may be cumbersome and inefficient for a user.
Thus, there is a need for a convenient portable scanner.
FIG. 7 is a block diagram showing alternate typical components of a scanner.
FIG. 8 is a block diagram showing alternate typical components of a scanner.
FIG. 9 is a light-processing diagram showing the operation of a typical optics configuration of the scanner.
FIG. 10 is a schematic diagram showing switches incorporated in the scanner in some embodiments.
FIG. 11 is a schematic diagram showing a visual output component incorporated into the scanner in some embodiments in a first state.
FIG. 12 is a schematic diagram showing a visual output component incorporated into the scanner in some embodiments in a second state.
FIG. 13 is a flow diagram showing steps typically performed by the system to monitor a scan for completeness.
FIG. 14 is a data flow diagram showing the flow of data between a storage component, data capture devices, and a computing device in some embodiments.
A device for interacting with rendered documents includes a scanner and memory is described. The device includes functionality capable of capturing visual information (such as via an optical scanning component) and/or audio information (such as via a microphone) from rendered documents or other information sources, and is also able to receive and store data from a separate computing device (such as via a USB port).
The device can include a small, stand-alone scanning device, or it may include at least part of another device, such as at least part of a pen-style device, at least part of a personal storage device, or at least part of an audio recording device, among numerous possibilities. The device can include one or more means to establish communication with at least one of a separate computing device or a network, such as a universal serial bus (USB) port. The device can be used both when such communication is currently established with a separate computing device or network (“on-line”), and also in the absence of any such established communication (“off-line”).
Information from rendered documents is scanned to the memory, and, in some embodiments, a user of the device is signaled when sufficient information has been obtained to determine at least one action associated with the scanned information. For example, the user may be signaled when sufficient information has been obtained to determine at least one document comprising the scanned information, or the user may be signaled when enough information has been has been obtained to determine a commerce operation, an annotation, a format operation, or identifying an advertisement.
Determining when sufficient information has been obtained may involve ascertaining a type or types of the scanned symbols, counts or relative positions of the scanned symbols of various types, an overall number of scanned symbols, a number of scanned words, a count of stop and non-stop words or symbols, or the frequency of occurrence of words or symbols of va
