Abstract: A digital camera is provided with a high dynamic range (HDR) mode of operation wherein a nominal exposure is automatically bracketed by one or more under exposures and one or more over exposures. The images thus obtained can then be used by suitable software to process the images to produce a final HDR image.

Abstract: A verifiable date stamp for use in portable electronic devices automatically and transparently determines within the portable device or devices the correct date and time that a document or image is created. By keeping periodic records of tests for accuracy of the date and time of the device(s), it will be possible to provide admissible evidence of the date stamps generated by the portable devices. The date stamp provided by the invention includes not only date and time but, in addition, GPS location (latitude, longitude and altitude) and time zone. In some embodiments which involve the use of video, the date stamp includes beginning and ending time and, optionally, average velocity, if any, for the time duration of the video clip.

Abstract: An interactive multimedia book provides hands-on multimedia instruction to the user in response to voiced commands. The book is implemented on a computer system and includes both text and audio/video clips. The interactive multimedia book is accessed by voiced commands and natural language queries as the primary user input. The displayed text is written in a markup language and contains hyperlinks which link the current topic with other related topics. The user may command the book to read the text and, as the text is read by the voice synthesizer, a word which is also a hyperlink will change its attributes upon being spoken. The user will be able to observe or hear this and simply utter the word which is the hyperlink to navigate to the linked topic.

Abstract: An interactive multimedia book provides hands-on multimedia instruction to the user in response to voiced commands. The book is implemented on an easy to use computer system which is suitable to various environments in which the book might be used. The interactive multimedia book is published on a computer readable medium with the necessary software to support the interactive operation of the book. Alternatively, the book may be downloaded form a remote site using a network, such as the Internet, in which case the content of the book and the necessary software are copied to a local medium, such as a computer hard disk. The content includes both text and audio/video clips. The interactive multimedia book is accessed by a computer system which is equipped with a microphone and voice recognition software. Voiced commands and natural language queries are the primary user input to the computer system.
