Abstract
A wireless keyboard with a built-in web camera, which allows a user to input text data and image data without being locally restricted by a wired connection to the computer. According to one preferred embodiment, a wireless keyboard with a built-in web camera is provided, comprising: a first input part for transmitting input key data inputted by a user to a user terminal device, a second input part for transmitting an image signal inputted from the web camera to the user terminal device, a packet generator for receiving the input key data and/or the compressed image signal and producing at least one packet according to a predetermined method, and a transmitter for transmitting the packet to a user terminal device.
Claims14
A wireless keyboard with a built-in web camera comprising, in combination:
- a first input part for transmitting input key data inputted by a user to a user terminal device;
- wherein said first input part comprises, in combination:
- (a) an input key signal generator for producing a scan code corresponding to an input key selected by said user;
- (b) an input key data generator for producing said input key data corresponding to said scan code;
- (c) an input key converter for converting said input key data into a predetermined code format;
- and
- (d) an input key transmitter for transmitting said converted input key data to said user terminal device via a wireless network;
- and
- a second input part for transmitting an image signal inputted from said web camera to said user terminal device;
- wherein said second input part comprises, in combination:
- (e) an image receiver for receiving said image signal;
- (f) an image compressor for adjusting and compressing said image signal;
- (g) an image signal divider for dividing said compressed image signal, based on data size of said compressed image signal and a predetermined data size for transmission, into a proper size based on said predetermined data size;
- and
- (h) at least one transmitter for transmitting said divided image signal to said user terminal device.
A wireless keyboard with a built-in web camera comprising, in combination:
- an input key signal generator for producing a scan code corresponding to an input key selected by a user;
- an input key data generator for producing said input key data corresponding to said scan code;
- an image receiver for receiving an image signal;
- an image compressor for adjusting and compressing said image signal;
- a packet generator for receiving at least one selected from a group consisting of said input key data and said compressed image signal and producing at least one packet according to a predetermined method;
- and
- at least one transmitter for transmitting said packet to a user terminal device.
A receiving part for receiving data from a wireless keyboard via a wireless network comprising, in combination:
- at least one receiver for receiving at least one selected from a group consisting of said input key data and said image signal which are transmitted from at least one transmitter embedded in said wireless keyboard;
- a packet combiner for determining whether said data received by said receiver are said input key data or said image signal and combining said data as a complete packet;
- a decoder for reproducing said data, if said data are compressed image signals;
- an image converter for converting said reproduced image signal into a data format suitable for a predetermined transmission protocol;
- an input key converter for converting said data into a data format suitable for a predetermined transmission protocol, if said data are said input key data;
- and
- an integrated transmitter for transmitting at least one selected from a group consisting of said converted image signal and said converted input key data to a user terminal device.
A wireless keyboard with a plurality of input keys comprising, in combination:
- an input key signal generator for producing a scan code corresponding to an input key selected by said user;
- an input key data generator for producing said input key data corresponding to said scan code;
- an input key converter for converting said input key data into a predetermined code format;
- and
- an input key transmitter for transmitting said converted input key data to said user terminal device via wireless network.
A wireless keyboard with a built-in web camera comprising, in combination:
- a keyboard with a plurality of input keys;
- a camera coupled to said keyboard for inputting an image signal;
- a converter for converting said input key data inputted from said keyboard and said image data inputted from said camera into a data format suitable for wireless transmission;
- and
- a transmitter for transmitting said converted input key data and said converted image signal to a receiving part.
