Abstract

Disclosed is a device combining the features of electronic cameras and Digital Signal Processors (DSPs) for capturing, storing, and transmitting still images and audio messages over the public switched telephone network. An accessory function is that of a standard telephone. While a camera is the focal function of the device, the DSP subsystem and its features are available for Geographical Positioning System (GPS) units and for other mobile platforms.

Enhanced Electronic Camera

      Disclosed is a device combining the features of electronic
cameras and Digital Signal Processors (DSPs) for capturing, storing,
and transmitting still images and audio messages over the public
switched telephone network.  An accessory function is that of a
standard telephone.  While a camera is the focal function of the
device, the DSP subsystem and its features are available for
Geographical Positioning System (GPS) units and for other mobile
platforms.

      The Figure is a block diagram of a DSP subsystem embodied
within a digital camera.  The DSP subsystem 10 is directly connected
to the camera control electronics 12 to handle communications and to
optimize functions for the camera.

      Basic digital cameras provide only the limited functions of
traditional cameras, such as image acquisition, automatic light and
speed adjustments, and the storage of images.  The system of the
Figure includes such features in the form of a CCD imager 14, control
switches 16 and image buffers 18 for the storage of images, along
with additional capabilities available through the programmability of
the DSP subsystem 10, which compresses an image as it is being
stored, dramatically reducing the amount of memory needed for each
image.  The user can choose among a variety of presentation,
compression, and transmission techniques available for use with
images.  Since programs can be loaded into DSP subsystem 10 after the
time of manufacture, enhanced functions can be added to an existing
device.

      The voice recognition facility of DSP subsystem 10 is used to
take pictures with the camera and to make adjustments.  Various
activities, including telephone connection, can be covered with fewer
than 100 commands, such as "Zoom in," "Retake 4," "Dial 243-7668,"
and "Encrypt message 8," spoken into microphone 20.  This feature may
be either speaker-independent or trained to recognize the voice of an
individual speaker.  This type of operation provides an advantage
over that of a traditional camera, since knobs and controls are
difficult to use while the user is looking through the camera
viewfinder.  However, switches 21 are also provided for use in
addition to the system of commands to cont...
