  • Patent number: 9910865
    Abstract: A method for storing digital images is presented. The method includes capturing an image using a digital camera system. It also comprises capturing metadata associated with the image or a moment of capture of the image. Further, it comprises storing the metadata in at least one field within a file format, wherein the file format defines a structure for the image, and wherein the at least one field is located within an extensible segment of the file format. In one embodiment, the metadata is selected from a group that comprises audio data, GPS data, time data, related image information, heat sensor data, gyroscope data, annotated text, and annotated audio.

  • Patent number: 9578224
    Abstract: A system and method for enhanced automatic monoimaging. Embodiments of the present invention are operable for configuring a first camera based on a configuration determination by a second camera. The method includes capturing a first image with the first camera and determining an optical configuration based on an optical measurement performed by a second camera. In one embodiment, the second camera comprises a lower resolution sensor than a sensor of the first camera. The method further includes sending the optical configuration from the second camera to the first camera and adjusting a configuration of the first camera based on the optical configuration. The method further includes capturing a second image with the first camera. The first image and the second image may be preview images.

  • Patent number: 9031393
    Abstract: An electronic system for enhancing camera focusing on a portable electronic device is disclosed. The system comprises a body, a bus, and a camera module coupled to the bus and comprising a photosensitive substrate and a lens assembly wherein the lens assembly comprises a lens capable of being selectively moved to a distance from the photosensitive substrate for light focus thereon. Further, it comprises an accelerometer coupled to the bus and configured to generate orientation information, said orientation information indicating contemporaneous orientation of the body with respect to a predetermined reference. It also comprises a memory and a processor coupled to the bus. The memory comprises instructions that when executed implement an autofocus program configured to automatically determine the distance based on: 1) image data captured by said camera module; and 2) the orientation information generated by the accelerometer.

  • Publication number: 20140307116
    Abstract: A system and method for initiating cooperative control over a mobile device configured to capture static images or images contained within a video sequence. The method includes obtaining an instruction on the mobile device from an external source. The method includes initiating an image controller on the mobile device, wherein the image controller controls an image capturing pipeline of the mobile device. The method includes determining that a raw image was captured by the mobile device. The method includes performing an action on the raw image based on the instruction.

  • Publication number: 20140071245
    Abstract: A system and method for stereoscopic image capture. The method includes capturing a first image with a first camera and capturing a second image with a second camera. The second camera comprises a lower resolution sensor than a sensor of the first camera. The method further includes determining a third image based on adjusting the first image to a resolution of the lower resolution sensor of the second camera and generating a stereoscopic image comprising the second image and the third image.
