Image Acquisition Toolbox

Description

The Video Input block is obsolete. It may be removed in a future version of the Image Acquisition Toolbox block library. Use the replacement block From Video Device.

The Video Input block opens, initializes, configures, and controls an acquisition device. The opening, initializing, and configuration occur once, at the start of the model's execution. During the model's run-time, the block buffers image data, delivering the latest image frame for each simulation time step.

The block has no input ports. The block has three output ports, corresponding to the uncompressed red, green, and blue color bands.

Note   The Video Input block supports only Windows video devices compatible with DirectX.
