摘要:
A digital camera has an integral flash and stores and displays a digital image. Under certain conditions, a flash photograph taken with the camera may result in a red-eye phenomenon due to a reflection within an eye of a subject of the photograph. A digital apparatus has a red-eye filter which analyzes the stored image for the red-eye phenomenon and modifies the stored image to eliminate the red-eye phenomenon by changing the red area to black. The modification of the image is enabled when a photograph is taken under conditions indicative of the red-eye phenomenon. The modification is subject to anti-falsing analysis which further examines the area around the red-eye area for indicia of the eye of the subject. The detection and correction can be optimized for performance and quality by operating on subsample versions of the image when appropriate.
摘要:
A method of filtering a red-eye phenomenon from an acquired digital image including a multiplicity of pixels indicative of color, the pixels forming various shapes of the image, includes analyzing meta-data information, determining one or more regions within the digital image suspected as including red eye artifact, and determining, based at least in part on the meta-data analysis, whether the regions are actual red eye artifact. The meta-data information may include information describing conditions under which the image was acquired, captured and/or digitized, acquisition device-specific information, and/film information.
摘要:
A digital image acquisition system having no photographic film, such as a digital camera, has a flash unit for providing illumination during image capture and a red-eye filter for detecting a region within a captured image indicative of a red-eye phenomenon, the detection being based upon a comparison of the captured image and a reference image of nominally the same scene taken without flash. In the embodiment the reference image is a preview image of lower pixel resolution than the captured image, the filter matching the pixel resolutions of the captured and reference images by up-sampling the preview image and/or sub-sampling the captured image. The filter also aligns at least portions of the captured image and reference image prior to comparison to allow for, e.g. movement in the subject.

The braking system of a vehicle is securely engaged in response to the operator of the vehicle causing the vehicle to stop. The vehicle being stopped is determined in response to several conditions including a predetermined time of stopping as well as suspensions settling time. The braking system remains securely engaged in the event of a moving vehicle colliding with the stopped vehicle. The braking system also remains securely engaged even if the foot of the operator is removed from the vehicle's brake pedal. The braking system is disengaged in response to the operator accelerating the vehicle, such as the operator's pressing of the vehicle's gas pedal, release of the vehicle's clutch and/or release of the vehicle's brake pedal. The rate of release of the braking system is responsive to the gas pedal position. The braking system is released rapidly in response to a substantially depressed gas pedal to facilitate a rapid start. The braking system is release gradually in response to a partially depressed gas pedal to facilitate a smooth start.

The invention is directed to temperature control system in which a temperature control apparatus for controlling the operation of at least one temperature-modifying device may include a thermostat housing; a controller to control the operation of the temperature modifying device in response to the electronic comparison of a measured ambient temperature with at least one set point temperature; and display for displaying information received from the controller; wherein the display may be oriented in a plurality of positions, allowing the thermostat housing to be mounted in a plurality of positions. In one embodiment, the display may be oriented in at least two positions that are rotated ninety degrees from each other using a jumper located in the controller.
摘要:
The braking system of a vehicle is securely engaged in response to the operator of the vehicle causing the vehicle to stop. The braking system improves vehicle safety by remaining securely engaged upon detection of a fault such as a vehicle collision, an unintentional transmission shift, a vehicle malfunction or a problem with the operator or operation of the vehicle. In the event of a collision, securely engaged brakes can significantly reduce resulting vehicle acceleration, potentially avoiding a secondary collision and reducing injuries experienced by the vehicle operator and passengers. In the event that no fault is detected, the braking system is disengaged in response to the operator accelerating the vehicle, either by pressing the gas pedal or releasing the brake pedal, thereby making the securely engaged brakes virtually unperceivable under normal operating circumstances. The braking system may be released rapidly in response to a substantially depressed gas pedal to facilitate a rapid start or gradually in response to a partially depressed gas pedal to facilitate a smooth start.
摘要:
A virtual reality system (200-323) stereoscopically projects a virtual reality images including a three dimensional image (245) having an interface image (250′) in a space observable by a user (100). The display system includes a substantially transparent display means (200) which also allows real images of real objects (850) to be combined or superimposed with the virtual reality images. Selective areas or characteristics of the real images are obstructed by a selective real image obstructer (860) to enhance viewing of selected virtual reality images while providing for viewing or real images or virtual images combined with real images in other viewing areas. The display system includes either a stereoscopic headset display system or a heads-up display system. The selective real images obstructer is a gray scale liquid crystal display included with the display system providing for adjustment of the size, shape and/or transparency of the obstruction of real images. The obstruction of real images may be adjusted in response to information for generating the virtual image, manual inputs or processing of real images by video cameras (310′ and 320′). Other selective real image obstructions include filtering a portion of the spectrum of visible light associated with the real images.
摘要:
A computer system stereoscopically projects a three dimensional object having an interface image in a space observable by a user. The user controls the movement of a physical object within the space while observing both the three dimensionally projected object and the physical object. The computer system monitors the position of the user to determine the position of the interface image within the space and further monitors the movement of the physical object to determine its position. A control signal is generated in response to the position of the physical object intersecting the position of the interface image. For example, a word processing program is indicated by an interface image such as an icon including the letter “W” three dimensionally projected within the space. The word processing program is activated when the user's finger moves within the space to touch the projected icon. The interface allows the user to observe the projected icon, physical finger and their intersection within the space. The physical object may also be extended with a stereoscopic extension image generated by the computer system in response to determining the position and orientation of the physical object.
