  2. Rolling shutter - Wikipedia

    en.wikipedia.org/wiki/Rolling_shutter

    Rolling shutter describes the process of image capture in which a still picture (in a still camera) or each frame of a video (in a video camera) is captured not by taking a snapshot of the entire scene at a single instant in time but rather by scanning across the scene rapidly, vertically, horizontally or rotationally. Thus, not all parts of ...

  3. Coded exposure photography - Wikipedia

    en.wikipedia.org/wiki/Coded_Exposure_Photography

    Digital Camera. Coded exposure photography, also known as a flutter shutter, is the name given to any mathematical algorithm that reduces the effects of motion blur in photography. The key element of the coded exposure process is the mathematical formula that affects the shutter frequency. This involves the calculation of the relationship ...

  4. Computational photography - Wikipedia

    en.wikipedia.org/wiki/Computational_photography

    The definition of computational photography has evolved to cover a number of subject areas in computer graphics, computer vision, and applied optics. These areas are given below, organized according to a taxonomy proposed by Shree K. Nayar [citation needed]. Within each area is a list of techniques, and for each technique one or two ...

  5. Focal-plane shutter - Wikipedia

    en.wikipedia.org/wiki/Focal-plane_shutter

    Focal-plane shutters may also produce image distortion of very fast-moving objects or when panned rapidly, as described in the Rolling shutter article. A large relative difference between a slow wipe speed and a narrow curtain slit results in distortion because one side of the frame is exposed at a noticeably later instant than the other and the object's interim movement is imaged.

  6. Shutter (photography) - Wikipedia

    en.wikipedia.org/wiki/Shutter_(photography)

    If a focal-plane shutter camera is left with sunlight falling on the lens (and the mirror up for an SLR), it is possible to burn a hole in the closed curtain of a non-metal shutter. Camera shake due to the impact of the larger curtains starting and stopping rapidly. Camera designers have learned to overcome SLR mirror-slap by including a mirror ...

  7. Active-pixel sensor - Wikipedia

    en.wikipedia.org/wiki/Active-pixel_sensor

    Since a CMOS sensor typically captures a row at a time within approximately 1/60 or 1/50 of a second (depending on refresh rate) it may result in a rolling shutter effect, where the image is skewed (tilted to the left or right, depending on the direction of camera or subject movement). For example, when tracking a car moving at high speed, the ...

    en.wikipedia.org/wiki/Automatic_number-plate...

    It is also important that the camera use a global shutter, as opposed to rolling shutter, to assure that the taken images are distortion-free. Because the car is moving, slower shutter speeds could result in an image which is too blurred to read using the OCR software, especially if the camera is much higher up than the vehicle.
