Camera with Projection Display

      Disclosed is digital camera having a projection display,
folding into a flat condition when not in use, which pops up into a
convenient viewing angle for use in aiming the camera and for
displaying and reviewing previously-recorded images.  The image
projected within the display is formed using a backlit Liquid Crystal
Display (LCD) panel.

      Figs. 1 and 2 are partly sectional side elevations of the
camera.  In Fig. 1, the camera is in a closed position.  In Fig. 2,
the camera is opened for picture taking and viewing.

      The camera includes a lens assembly 12, aimed in the direction
of arrow 14, for taking pictures.  An upper portion 16 of camera

portion 16 is pivoted downward, as shown in Fig. 1, the camera can be
conveniently carried, due to its small size and flat shape.  When
this upper portion 16 is pivoted upward, as shown in Fig. 2, an image
formed at LCD panel 22, which is backlit using a projection lamp 23,
is projected through an internal lens 24 to be focused on a coated or

      As the camera is opened, LCD panel 22 pivots upward about pin
28, by which it is pivotally mounted, to lie parallel to the screen
26.  Internal lens 24 pivots with the LCD panel 22 and moves away

projection lamp 23 also rotates upward to...
