Hand-manipulated electronic camera tethered to a personal computer
First Claim
1. A portable, electronic camera connectable to a computer for capturing an image and providing the captured image to the computer for storage therewith, said camera comprising:
- signal connection means for linking the camera to the computer;
means for sensing an image;
means for driving said sensing means to generate an image signal corresponding to the image, and for applying the image signal to said signal connection means for transmission to the computer;
operative means for conditioning the camera for image capture in response to the readiness of the computer for accepting an image signal, said operative means responsive to a status signal from the computer transmitted through said signal connection means, whereby the computer is adapted for storage of the image signal after providing the status signal; and
exposure release mean connected to said driving means for initiating the generation of an image signal, thereby capturing an image, and wherein said operative means inhibits actuation of said exposure release means until receipt of said status signal indicates that the computer is ready to receive the image signal.

Abstract
A portable, electronic camera is connectable to a computer for capturing an image and providing the captured image to the computer for storage therewith. The camera ergonomically acts like an independent, self-functioning peripheral device while in actuality depending on instructions from the computer. The camera is remotely linked to the computer, e.g., by a cable, thereby allowing mobility of the camera independent of the computer. The camera includes an electronic image sensor, and circuit for driving the sensor to generate an image signal that is applied to the computer through the remote link. The readiness of the computer to accept an image signal is manifested by operative device in the camera, which condition the camera for image capture in response to a status signal from the computer transmitted through the remote link. In one embodiment, a capture switch is positioned on or with the camera for user engagement, whereby the operative device inhibits actuation of the capture switch until receipt of the status signal. In another embodiment, the operative device energizes an exposure readiness indicator when the status signal is received.
