摘要:
A digital camera takes interleaved photographs of two different kinds. In one example embodiment, the first kind of photograph is taken using a first set of pixels of the camera's electronic array light sensor and has a short exposure time. The second kind of photograph is taken using a second set of pixels and has a long exposure time. More than one of the short-exposure-time photographs is taken while each long-exposure-time photograph is exposed. The two kinds of photographs are used for different purposes. For example, one kind may be used for performing automatic focusing while the other kind is used for displaying in a live view display. In this way, live view may continue while automatic focusing is performed. In another embodiment, one kind of photograph is used for providing a live view display, and the other is used in selecting exposure settings for a final photograph.

The shutter of a digital imaging device may be calibrated by comparing a characteristic of two separate exposures obtained from a single field of the device's imaging sensor during a single exposure cycle. Calibrating the shutter in this manner facilitates the accuracy of even very short exposure times.

Autofocus methods and digital cameras employing a holographic element or hologram. The holographic element generates one or more displaced images that are processed to generate a bipolar contrast signal that provides for improved autofocus performance of the digital camera.

Viewfinder apparatus, methods, and digital cameras that provide autofocus using retroreflected eye focus measurements. When a user looks at a part of a scene that is the intended subject of the image, his or her eye is correctly focused. The present invention measures the focus distance of the eye when the eye is focused on the desired location in the scene, and then uses the measured distance to set the focus of the camera.

In one embodiment there is shown a method for capturing data, the method comprising sensing a first signal, capturing an auto exposure (AE) image in response to a sensed first signal, the auto exposure image captured with settings based upon preestablished criterion, and upon the AE image being captured, determining if a second signal has been sensed, and if the second signal has been sensed, capturing a speculative full exposure image, and if the captured speculative full exposure is determined to be acceptable, reading the remainder of the captured speculative image.

A method for creating an instant review image is disclosed. The method starts by creating image data by exposing an image sensor to a scene. A first sub-set of the image data is transferred from the image sensor and used to create an instant review image. The rest of the data is transferred from the image sensor and essentially all of the data from the image sensor is used to create a second image.

摘要:
A method includes receiving user input associated with configuration of a configurable device. The method also includes retrieving a template associated with the configurable device. The method further includes generating one or more configuration commands for the configurable device using the template and the user input. In addition, the method includes storing the commands and/or outputting the commands. The method could also include retrieving one or more rules associated with the configuration of the configurable device. The one or more rules could define at least one allowable configuration of the configurable device. Also, the user input could include one or more selections associated with one or more configuration options by a user, and the one or more rules could define the one or more configuration options available for selection by the user. The configurable device could represent a switch, a router, or other command-line configurable device.
