Digital camera having display device for displaying graphical representation of user input and method for transporting the selected digital images thereof

Abstract: A method and apparatus for transporting digital images is provided. In one embodiment, a personal electronic handheld digital camera executes an application program that enables a user of the camera to send one or more digital images, formed by and stored in the camera, from the camera to a destination. One or more addresses describing one or more destinations are selected or identified. One or more stored digital images are selected and associated with the one or more addresses. Optionally, a voice message is recorded and associated with the one or more addresses. The camera is coupled to a data communication network, and a transport operation is initiated. Under control of the application, the camera sends the selected images to the designated destinations over the data communication network. When an address is a physical address, for example, a postal mail address, the selected images are automatically routed to a central server. At the central server, tangible copies of the selected images are printed, packaged, and sent to the physical address. Each image may be marked with an authentication stamp that uniquely identifies the image or the camera that created the image, guarding against unauthorized alteration.

Automatic image retargeting with fisheye-view warping

Abstract: Image retargeting is the problem of adapting images for display on devices different than originally intended. This paper presents a method for adapting large images, such as those taken with a digital camera, for a small display, such as a cellular telephone. The method uses a non-linear fisheye-view warp that emphasizes parts of an image while shrinking others. Like previous methods, fisheye-view warping uses image information, such as low-level salience and high-level object recognition to find important regions of the source image. However, unlike prior approaches, a non-linear image warping function emphasizes the important aspects of the image while retaining the surrounding context. The method has advantages in preserving information content, alerting the viewer to missing information and providing robustness.

System and method for applying inference information to digital camera metadata to identify digital picture content

Abstract: The present invention is directed to a system and method for correlating an image with information associated with the image comprising identifying image metadata for the image, wherein the image metadata includes information associated with conditions at the time of image capture, searching one or more information sources using parameters in the image metadata to collect inference information from the information sources, and displaying the inference information to a user.

Method and system for assessing the photo quality of a captured image in a digital still camera

Abstract: A method for assessing the photo quality of a captured image in a digital camera comprises the steps of checking in-camera the photo quality of the captured image to determine if the photo quality is acceptable, and providing a corresponding photo quality feedback to a camera user.

Slanted-Edge MTF for Digital Camera and Scanner Analysis

Abstract: The development and adoption of standards for the evaluation of digital camera resolution has helped foster the widespread use of slanted-edge-based analysis. In addition, the form of these evaluation methods suggests their use in imaging system analysis and design. The standards-specific methods and algorithms, however, are not intended for direct MTF evaluation, but if care is taken to avoid bias and minimize random error, the methods can successfully be used for this purpose. In this paper the influence of several variables are discussed. Specifically, the effect of color misregistration, edge location estimation, data-record length and image noise on the measured MTF are addressed.
