Digital camera architecture with improved performance

Abstract: A digital camera acquires a first image in a sequence of images by loading it into a unified memory space of the digital camera in a first order and processing it in a second order Before the first image is completely processed, the digital camera starts acquiring a second image and overwriting at least a processed portion of the first image in the unified memory space with image data of the second image

Depth from defocus calibration

Abstract: A device and methods are provided for calculating depth estimation for a digital imaging device are disclosed and claimed. In one embodiment, a method includes detecting a first image associated with a first focus parameter, detecting a second image associated with a second focus parameter, calculating a statistical representation of a region of interest in the first and second images, and determining a ratio for the region of interest based on the statistical representation. The method may further include determining one or more focus characteristics using a memory table based on the determined ratio for the region of interest, and calculating a focus depth for capture of image data based on the determined one or more focus characteristics associated with the memory table.

Method of selectively making contact structures both with barrier metal and without barrier metal in a single process flow

Abstract: A semiconductor structure with ohmic contacts and variable resistance contacts has an interconnection pattern to the contacts including a first barrier metal in contact with the variable resistance contacts and a second metal contacting the barrier metal and the ohmic contacts. The barrier layer protects the amorphotized crystalline structure of the variable resistance contacts. Fabrication processes are described.

VLSI implementation of an image compression algorithm with a new bit rate control capability

Abstract: An image compression algorithm with a new bit rate control capability is presented. The bit rate control technique is developed for use in conjunction with the JPEG baseline image compression algorithm. The new method is an extension of the previously developed algorithm which is implemented in the Zoran 031 image compression chip set. The chip set comprises a discrete cosine transform (DCT) processor and an image compression coder/decoder. Both methods and the chip set are discussed in detail. >

Method and apparatus for securing transfer of and access to digital content

Abstract: A method and apparatus for securely accessing digital content is provided. The method of providing secure access to content comprises determining an identification (ID) from a secure medium including content. The method further comprises sending a session key and the ID to a server. Furthermore, the method includes requesting user authentication and if the user is successfully authenticated, receiving the session key from the server to enable reading of the content on the secure medium.
