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： Apparatus, systems, and methods disclosed herein may transpose image blocks from successively-captured versions of an image according to relative movement between an image capture device and the scene being captured. The transposition may provide for alignment of the successively-captured images notwithstanding the movement. The transposed image blocks from the successive images are composited in the frequency domain by integrating frequency domain coefficients from each into a composite final image. Additional embodiments are disclosed.

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.
