摘要： Embodiments of the claimed subject matter are directed to methods for automatic white balancing in an image-capture device. In one embodiment, given an estimated illuminant color (e.g., derived from the Gray World method), a more optimal illuminant color can be found by projecting this point to a plot of common illuminants to determine the closest point on the plot of common illuminants. Once the closest point of the plot of common illuminants is derived, the actual image (e.g., pixel) data of the scene is adjusted by the value of the closest point on the plot of common illuminants so that the light is normalized for the scene.

摘要： Apparatus, systems, and methods disclosed herein may estimate the magnitude of relative motion between a scene and an image capture device used to capture the scene. Some embodiments may utilize discrete cosine transform and/or Sobel gradient techniques to identify one or more blocks of pixels in an originating calibration image frame. Matching blocks of pixels may be located in a successive calibration image frame. Motion vectors originating at one calibration frame and terminating at the other calibration frame may be calculated. The magnitude of relative motion derived thereby may be used to adjust image capture parameters associated with the image capture device, including exposure settings.

摘要： Methods, apparatus, and systems may operate to more efficiently utilize data stored in an array of storage blocks organized as rows and columns of contiguous blocks, where non-linearity is present in the data. Activities may include organizing data to discard useless elements from storage blocks when transferring the data to a memory buffer, and perhaps compressing the data for increased memory density utilization. Additional activities may include reconstructing data stored in the memory buffer and using an image distortion formula to display a linear representation of the non-linear data.

摘要： A digital stereo camera using a single sensor array to take both left and right images for stereo (three-dimensional) image capture. In one embodiment, a micro-lens array is used to focus, at a first instant in time, light (“left light”) from a left lens system onto a sensor array for left image capture. Then, the micro-lens array is moved to focus light (“right light”) from a right lens system onto the sensor array for right image capture. In another embodiment, a portion of the left light (the portion having a first polarized direction) and a portion of the right light (the portion having a second polarized direction) are directed to a sensor array; the second polarized direction being orthogonal to the first polarized direction. To capture the left image, a polarization filter is used to allow the left light (having the first polarized direction) to pass toward the sensor array while preventing the right light (having the second polarized direction) from reaching the sensor array. To capture the right image, polarization direction of the polarization filter is switched to allow only the right light (having the second polarized direction) to reach the sensor array.

摘要： Pictures can be taken with multiple (e.g., two) cameras, and the statistics associated with any of those pictures can be used to correct (e.g., color balance) any of the other pictures. Generally speaking, first image data captured by a first camera is accessed (e.g., retrieved from memory). Similarly, second image data captured by a second camera is accessed. The first image data and second image data are acquired at or about the same time using the first and second cameras together (e.g., at the same location, so that each camera is subject to the same light source). The first image data can then be processed (e.g., color balanced) using information that is derived using the second image data.

摘要： Pixels in an imaging device pixel array are sized according to their geographic location in the pixel array to compensate for various optical characteristics/issues. In one example, pixel size is increased according to the distance of the pixel from the x-axis and/or the y-axis of the pixel array to correct for lens shading.
