Patent ID: 8854497

Claim:
A webcam capable of generating special sound effects, the webcam comprising: an image device for capturing and processing an image to generate a processed image, and storing the processed image; a sound device for capturing and processing sound to generate a processed sound, and storing the processed sound, wherein the sound device comprises: a sound capture unit for capturing and digitizing the sound to generate a digitized sound, wherein the digitized sound is real-time sound; a sound processing unit for performing sound processing on the digitized sound to generate the processed sound, wherein the sound processing comprises a sound mixing, the sound processing unit multiplies the digitized sound by a first weight to generate a first sound and multiplies a non-real time digitized sound by a second weight to generate a second sound, and the sound processing unit executes the sound mixing on the first sound and the second sound to output the processed sound; and a sound buffer coupled to the sound processing unit for receiving and storing the processed sound; a multiplexer coupled to the image device and the sound device for receiving the processed image and the processed sound; a microprocessor coupled to the image device and the sound device for controlling the image device and the sound device; and a Universal Serial Bus device coupled to the multiplexer and the microprocessor for controlling the multiplexer to read the processed image from the image device and read the processed sound from the sound device according to a command of a host, and transmitting the processed image and the processed sound to the host.
