Abstract

A method and apparatus for controlling and displaying the image information presently seen by the image capture device together with those images which have been captured and stored upon actuation of the device. In a preferred embodiment, a viewfinder window is located in a capture device window. The capture device window also includes a variety of push buttons, some of which control the image capture device, others of which control the way in which the captured images are displayed on the computer screen. In response to the user command to capture an image, the image will be displayed adjacent to the image capture window. As the user continues to capture images, the frames are displayed as long as the computer has adequate temporary storage. Means to discard some images are also included in the user interface. Preferably, the discarded images are retained to allow the maximum reversibility of decisions to the discard images. The user interface also allows the user to stack a set of images into a single object in the workspace. Images may be manipulated within the stack, discarded or modified or changed between stacks of image objects.
