Abstract
According to one aspect of the present invention, a wireless telephony device is equipped with an optical image sensor, and a lens for imaging an object onto the sensor. The optical sensor permits a variety of useful functionality, including decoding of bar codes, watermarks, etc., from objects imaged by the sensor. One application of such a device is to interact with a remote computer system using data decoded from a bar code or watermark. For example, the device can be used to scan image data from an item depicted in a catalog, and then to transmit an order for the item from the catalog's on-line web store—using digital data decoded from the image to identify the desired item.
Claims12
In a wireless telephony device including a microphone, a modulator, and an RF amplifier, the device serving to receive and transmit RF signals conveying audio data, an improvement comprising:
- a display screen;
- an optical sensor having plural sensing elements and producing image data;
- a lens for imaging an object onto the sensor;
- and
- a processor for discerning plural-bit data steganographically encoded within said image data and for directing an action based on said plural bit data;
- wherein said action based on said plural-bit data comprises presenting information obtained from a remote computer on said display screen.
In a wireless telephony device including a microphone, a modulator, and an RF amplifier, the device serving to receive and transmit RF signals conveying audio data, an improvement comprising:
- a display screen;
- an optical sensor having plural sensing elements and producing image data;
- a lens for imaging an object onto the sensor;
- and
- a processor for discerning plural-bit data steganographically encoded within said image data and for directing an action based on said plural bit data;
- wherein said action is establishing a telephonic link to a phone number determined by reference to said plural-bit data.
In a wireless telephony device including a microphone, a modulator, and an RF amplifier, the device serving to receive and transmit RF signals conveying audio data, an improvement comprising:
- a display screen;
- an optical sensor having plural sensing elements and producing image data;
- a lens for imaging an object onto the sensor;
- and
- a processor for discerning plural-bit data steganographically encoded within said image data and for directing an action based on said plural bit data;
- the device further including a GPS system for determining location of the device, and said action is a first action if the GPS system determines the device is in a first location, and said action is a second, different action if the GPS system determines the device is in a second, different location.
In a wireless telephony device including a microphone, a modulator, and an RF amplifier, the device serving to receive and transmit RF signals conveying audio data, an improvement comprising:
- a display screen;
- an optical sensor having plural sensing elements and producing image data;
- a lens for imaging an object onto the sensor;
- and
- a processor for discerning plural-bit data steganographically encoded within said image data and for directing the device to transmit at least some of said plural-bit data to a remote system for further action.
A method of operating a cell phone, including:
- capturing image data using a 2D image sensor included with said cell phone;
- discerning plural-bit data steganographically encoded in said image data;
- at least in part by reference to said plural-bit data, determining an identity of a remote system;
- and
- establishing communication between said remote system and the cell phone thru a link that includes a cellular network.
