A method of focusing a digital camera module with an image sensor including capturing an image of a test target with the digital camera module, determining a focus quality of the image with the image sensor, outputting a signal related to the focus quality of the image from the digital camera module to a focusing station external to the digital camera module, and determining whether a position of a lens from the image sensor within the digital camera module should be altered to improve a focus quality of subsequently captured images.
摘要:
A method and apparatus for intelligent distributed analyses of images including capturing the images and analyzing the captured images, where feature information is extracted from the captured images. The extracted feature information is used in determining whether a predefined condition is met, and the extracted feature information is transmitted for further analysis when the predefined condition is met. The extracted feature information is stored and is used to generate statistical information related to the extracted feature information. Further, additional feature information is provided from other databases to implement further analysis including an event detection or recognition. Accordingly, distributed intelligent analyses of images is provided for analyzing captured images to efficiently and effectively implement event detection or recognition.
摘要:
A pointing device having a laser in a handheld housing is disclosed. The laser generates a light beam that exits the housing. A beam steering assembly causes the light beam to move relative to the housing. The pointer includes a housing orientation sensor that measures the orientation of the housing. A controller operates the beam steering assembly to compensate for changes in the housing orientation. Embodiments based on housing orientation sensors constructed from a gyroscope and a camera are described. In addition to stabilizing the light beam location, embodiments in which the beam steering assembly also causes the light beam to execute a fixed pattern can also be constructed.

An image processing system uses centralized image correction data to process digital images. The image processing system includes a centralized database for storing image correction data for imaging devices. An image processor that receives image data representing an image captured by one of the imaging devices accesses the centralized database with a key associated with the imaging device to retrieve the image correction data for the imaging device. The image processor processes the image data using the retrieved image correction data to correct the image data by reducing various noise components in the image.

A method and apparatus for detecting a location of an eye of a user using an automated detection process, and automatically determining a position of a head of the user with respect to an object based on the detected location of the eye. A location of an eye of a user inside a vehicle is detected using the automated detection process, at least one of height and orientation information of the user is automatically determined based on the detected location of the eye, and a mechanical device inside the vehicle is controlled in accordance with the determined information. Moreover, an eye blinking pattern of a user is detected using an infrared reflectivity of an eye of the user, and messages are transmitted from the user in accordance with the detected eye blinking pattern of the user.
