The present invention provides a technique for providing color corrected images to a user over a network. In particular, the present invention allows multiple image providers to provide color corrected images to a user when the user's computer and its associated devices are not calibrated and/or characterized, or the calibration and/or characterization data is not available over the network to the image providers. This abstract is provided for the sole purpose of complying with the rules requiring an abstract to allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure contained herein. This abstract is submitted with the express understanding that it will not be used to interpret or to limit the scope or the meaning of the claims.

Method and system for improved internet color

The present invention provides a technique for providing color corrected images to a user over a network. The user's computer and its associated devices may be remotely calibrated and or characterized and the data made available over the network to permit multiple image providers to provide color corrected images to a user. A notification technique is also provided to notify a user when the image or images being displayed is color corrected. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

System and method for providing high fidelity color images

Remote color characterization for delivery of high fidelity images

Compressed image files are partially preprocessed to expedite color correction and delivery of color corrected images. Color correction may be accomplished by processing only the luminance channel, only the color channels, or a combination of the luminance and color channels. A method for adjusting characteristics of a compressed image file including compressed characteristics elements and compressed image elements, includes: in the compressed image file, separating the compressed characteristics elements and the compressed image elements; decompressing one or more of the compressed characteristics elements; and adjusting the decompressed characteristics elements.

Method and system for fast image correction

The present invention provides a technique for modeling the tone reproduction curve of a flat panel screen such as an LCD. The technique employs a second order function to predict the luminance output as a function of the input voltage based upon two known input values. This abstract is provided for the sole purpose of complying with the rules requiring an abstract to allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure contained herein. This abstract is submitted with the express understanding that it will not be used to interpret or to limit the scope or the meaning of the claims.

Method and system for characterizing color display monitor output

A system and method for providing critical end user feedback as to the color correction status of imagery shown on a client display, thus notifying the user that the color image being viewed is color accurate. In particular, the invention includes server and or client based applets which automatically informs viewers and/or other receivers of digital images as to the state of color correction for a particular digital image, thus notifying a viewer of the visual integrity of the digital image being displayed. The notification may be an icon that provides users with a visible indication about the integrity of color imagery currently being viewed by the client at a specific web site. It does this by briefly flashing the cursor for a fraction of a second to indicate if whether or not the page is being viewed utilizing calibrated color. This icon can be implemented in addition, or instead, in the OS, in a web-enabled application, or in a browser (when implemented on as a client-side application); or it can be implemented as an image, tag, program, or watermark embedded within a web page by the web server or by any of the links between server and client within the network infrastructure.

High fidelity image delivery with color correction notification

Method and apparatus for displaying notification that a color corrected image is being viewed

An I/O port locking computer security system is implemented in the power management module of the hardware-software interface program (BIOS). A hotkey sequence of keystrokes activates the portlock feature and a system management interrupt signal (SMI) is generated. A SMI handler routine receives the interrupt signal and generates a signal to a hardware device handler. The device handler receives the signal and then disables various data transfer I/O ports on the computer (e.g., serial, parallel, fax, modem, floppy drives, and infrared communication ports). I/O ports in the disabled state cannot be accessed. Thus, data in the computer cannot be transmitted, copied, or 'beamed' via infrared, to an unauthorized system or medium. I/O ports in the disabled state are enabled after receiving a password and a SMI interrupt signal is generated. A SMI handler receives the interrupt signal and generates a signal to a hardware device handler. The device handler receives the signal and then enables various I/O ports on the computer. Enablement or disablement of the portlock feature, the hotkey keystroke sequence, and the password are maintained in CMOS computer memory. Such elements can be altered in the computer BIOS setup program.
