Abstract: A digital camera is provided, comprising an image system having a unique combination of features that aid in generating creative, high-quality images. The system presents a variety of overlays, each having prescribed attributes, e.g., ranging in size, opacity, and functionality, and from iconic overlays to full-scale overlays having varied opacity. The overlays can be used as an aid in composing a live image for digital capture, either as a constant or intermittent presence on the view-screen of the camera. In an exemplary embodiment, the camera can create a composite photograph in which a live image and the overlay are combined together. In an independent aspect, the camera can include an auto-compositing feature that aids in creating images free of improperly exposed regions. Thus, a photographer can create and combine images “on location” in a unique manner.

Abstract: Method and apparatus are described for outputting data from a device, such as a portable keyboard, directly to a keyboard interface 40 of a destination computer 42. The device may be detached from the computer and operate remotely therefrom, in an "active mode" wherein keystroke data is stored in internal memory thereof, for subsequent transfer to the destination computer. Alternatively, the device may be attached to the computer and function in a "bypass mode" (or in a keyboard emulation routine of the active mode) as a standard input keyboard therefor. The destination computer 42 may be a personal computer or a terminal of a mainframe computer. The internal circuitry of the device includes a programmable processor 28, a program memory 30, a working memory 32, an input switch device 34, a display 36 and an output interface 38. A bypass switch device 24 permits the device to operate in the bypass mode. A resident program stored in program memory 30 controls input, editing, translation and output of data.
