摘要： An image sensor is formed with shifts among the optical parts of the sensor and the photosensitive parts of the sensor. The optical parts of the sensor may include a color filter array and/or microlenses. The photosensitive part may include any photoreceptors such as a CMOS image sensor. The shifts allow images to be formed even when the light received at a given pixel location varies in angle of incidence as a function of pixel location within the array. The relative shifts among the pixel components may be, for example, plus or minus some fraction of the pixel pitch. The shift may be variable across the array or may be constant across the array and may be deterministically determined.

摘要： An image capture sharpening subsystem for a digital camera includes a capture sharpening processor and a memory that stores values for a capture sharpening amount. The values for the capture sharpening amount are a function of position on an image sensor of the digital camera. The capture sharpening processor receives a first value for a pixel in an image captured by the image sensor and a position value for the pixel on the image sensor. The capture sharpening processor determines a pixel sharpening amount from the values for the capture sharpening amount stored in the first memory according to the position value. The capture sharpening processor applies a capture sharpening process to the pixel to provide a second value for the pixel according to the pixel sharpening amount and stores the second value in a second memory that provides a sharpened version of the image captured by the image sensor.

摘要： A method and system for hiding objectionable frames during autofocusing are disclosed. A personal electronic device such as a cameral telephone can have two cameras that have overlapping fields of view. One camera can provide imaging. The other camera can facilitate autofocusing in a manner wherein images produced thereby are not viewed by a user. Because the autofocus frames are hidden, the user is not distracted or annoying thereby.

摘要： A method performed by an electronic camera in flash mode is as follows. A scene ambient lighting indication is obtained. An integration time interval and a flash pulse-on time interval for taking a picture is then set. The set integration time interval is shorter when the indication is bright than when the indication is dark; and the set flash pulse-on time interval is longer when the indication is bright than when the indication is dark. An image is captured using the set integration time interval and the set flash pulse-on time interval in accordance with an electronic rolling shutter (ERS). Other embodiments are also described and claimed.

摘要： Systems and methods are providing for navigating a three-dimensional model using deterministic movement of an electronic device. An electronic device can load and provide an initial display of a three dimensional model (e.g., of an environment or of an object). As the user moves the electronic device, motion sensing components, positioning circuitry, and other components can detect the device movement and adjust the displayed portion of the three-dimensional model to reflect the movement of the device. By walking with the device in the user's real environment, a user can virtually navigate a representation of a three-dimensional environment. In some embodiments, a user can record an object or environment using an electronic device, and tag the recorded images or video with movement information describing the movement of the device during the recording. The recorded information can then be processed with the movement information to generate a three-dimensional model of the recorded environment or object.

摘要： An electronic camera device has an imaging sensor to capture an image of a scene, a flash to illuminate the scene for capture by the sensor, and an evaluator to detect a condition in the scene. A redirector shifts the peak of a spatial energy profile of light from the flash. The peak is shifted from being aimed at one region in the scene to being aimed at another region in the scene, in response to the evaluator having detected the condition in the scene. Other embodiments are also described and claimed.

摘要： A lens assembly includes a brush-like baffle between the lens and a transparent cover. The baffle at least partially surrounds the lens to prevent stray light from entering and causing flare or other image artifacts. If the baffle does not entirely surround the lens structure, an adjustment mechanism may be provided to rotate the baffle so as to “tune” a flare reduction effect.

摘要： A device to emit light includes a light emitting diode (LED) die and a light guide coupled to the LED die. The light guide includes a first material having a first index of refraction with a plurality of apertures arranged in a grid. A second material having a second index of refraction that is larger than the first index of refraction fills the plurality of apertures. Each aperture extends from a first end adjacent the LED die to a larger second end. The first end may be a circle of approximately 1 to 2 μm in diameter. The distance between the first and second ends may be from approximately 10 to 20 μm. Each aperture may be in the form of a frustrated cone having an included angle between the sides from approximately 3 to 7 degrees. The light guide may be formed on a transparent substrate.
