One embodiment of a system for rendering media files comprises a computer configured to determine media file formats that are used by media rendering devices connected to a network and to determine media files available on the network. The computer generates media shadow files of media file formats used by the media rendering devices to accompany existing media files available on the network in alternative formats.

Media shadow files and system

A method and device for adjusting white balance are disclosed herein. The method may comprise generating data representative of an image with and without the use of a strobe. The contribution of the strobe and the contribution of ambient light are on the data are calculated. Based, in part, on the contributions of the ambient light and the strobe, a weight is calculated. The weight is applied to the data in order to adjust the white balance.

Method and device for adjusting white balance

An integrated image sensor for acquiring and processing electrical signals representative of an object comprising a photosite array configured to convert light into the electrical signals, an A/D converter configured to convert the electrical signals into digital data, and logic integral with the image sensor configured to scale the digital data by a non-integer-scaling factor. A method for acquiring and processing image data with an integrated image sensor comprising the steps of capturing, via the image sensor, the image data representative of an image, scaling, via the image sensor, the image data by a non-integer value, and outputting from the integrated image sensor scaled image data.

Methods of sampling a surface having a micro-texture upon which an optical navigation circuit tracks movement. An embodiment of the method comprises determining a rate for taking samples of the surface, determining an exposure level of the surface, illuminating the surface at the determined rate for taking samples, and illuminating the surface for each of the samples with pulses of light at the determined exposure level.

Methods of sampling a surface having a micro-texture

A digital camera system is provided for capturing pictures of scenery or scanning the text of a document. A lens of the digital camera system receives light from a scene, and a conversion device defines a first set of digital data based on this light. A scanning mechanism included within the digital camera system scans a document as the system is passed over the surface of the document and produces a second set of data that defines an image of the document. An audio signal interface included within the digital camera system receives an audio message and defines a third set of digital data based on the audio message. A system controller stores the first, second, and third sets of data into a storage device. If desired, the first and second sets of data may be merged together to define a combined image depicting at least a portion of the scene defined by the first set of digital data and depicting at least a portion of the document defined by the second set of digital data.

Digital camera system and method capable of performing document scans

An optical navigation system saves power by pulsing its surface illumination light source to provide light only when needed. The level of light may be controlled by a servo-mechanism that monitors degree of correlation data and average illumination, and that changes the controlled level at times when it is both required and safe to do so. As for creating different levels of illumination, that maybe accomplished by: (1) pulsing the light on and then opening the electronic shutter for some period of time during the pulse (gating the light); (2) opening the shutter and then varying the pulse width of the light (gating the LED); (3) opening the shutter and then pulsing the LED at different intensities; and (4) a combination of(2) and (3). In addition, the velocity of the navigation circuit over the surface (or vise versa) can be determined, and in cases where it is safe to assume that limited acceleration is possible, at low velocities it is desirable to reduce the rate of data acquisition, and thereby pulse the light source less often and conserve power.
