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 ...
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 ...
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.
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 ...
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 ...
On the software side, they are constantly looking to develop more powerful solvers, to better utilize computer resources, and to include engineering knowledge in pre and post-processing. On the process side, they try to achieve a better alignment between 3D CAE, 1D system simulation, and physical testing.

A new architecture in the Expeed 3 (ARM) offers a highly increased speed in its image processor (with even two pipelines on the EI-160), its H.264 video encoder and is controlled by a dual-core ARM architecture microcontroller replacing the Fujitsu FR.
