Abstract:
Method of displaying a sequence of images from a digital videocamera on a video display unit, the method beingcharacterized by the steps of advancing the field of view of the camera is discrete steps across the object being viewed to capture a sequence of contiguous images, temporarily storing a digital representation of a first of the images in a first buffer store and a digital representation of at least part of the next succeeding image in a second buffer store, controlling the data in the two buffer stores such that the data follows the leading edge of the advancing viewport and data in the first store representing a trailing increment strip of the first stored image is progressively discarded while data in the second store representing a trailing increment strip of the next contiguous image is transferred to a location in the first store occupied by the data representing a leading incremental strip of the first stored image, and reading out the contents of the first buffer store to the display unit.
