Digital Camera Patent Description
BACKGROUND OF THE INVENTION
[0001] 1) Field of the Invention
[0002] The present invention relates to a refracting device for
display of digital camera, more specifically, to a refracting device
installed around the image display. By way of refraction on the
mirror face, the user is allowed to view the image on the display
from another visual angle.
[0003] 2) Description of the Prior Art
[0004] Digital camera typically is installed with a display, such
that the user can view the captured picture immediately. Therefore,
the users generally do not perform aiming or focusing through the
traditional window while taking a picture, unless the object stay
in a special environment or is illuminated by unusual beams. The
said display can be classified as a small scale Liquid Crystal Display
(LCD, for short), which is a kind of flat display among opto-electronic
products, and features small volume, light weight, thin thickness,
low power consumption, flash-free, radiation-free. However, generally
speaking, as LCD is applied to display based on the effect of electro-optical
and the characteristic of polarized light, which have the deficiency
of optical dead-zone, i.e., the image on the display becomes invisible
when the visual angle of user is significantly slanted or beyond
the refracting angle of LCD image, the range of view-finding is
limited. Therefore, for the user who has to raise or lay down the
digital camera or take the picture of wide range, which is possible
especially at a multitudinous scene or at the occasion that needs
special view-finding angle, the LCD display becomes invisible and
useless.
[0005] To solve those deficiencies stated above, the inventor designed
a refracting device such that, in an optical dead-zone, the user
can view the display image through the refraction and thus ameliorates
the deficiencies disclosed above.
SUMMARY OF THE INVENTION
[0006] The main objective of this refracting device for display
of digital camera is to provide a refracting device, such that,
by way of the refraction, even in an optical dead-zone, the user
can view the image shown on the display, the effective visual angle
of view-finding is significantly increased, and the problem caused
by optical dead-zone of LCD display is thus solved.
[0007] To further describe the technical details of the present
invention, the preferred embodiments together with the accompanying
drawings are described in the following.
BRIEF DESCRIPTION OF THE DRAWINGS
[0008] FIG. 1 is a composite view of the present invention.
[0009] FIG. 2 is an operational view of the present invention.
[0010] FIG. 3 is another operational view of the present invention.
[0011] FIG. 4 is an exploded view of another embodiment of the
present invention.
[0012] FIG. 5 is an operational view of another embodiment of the
present invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0013] Firstly, referring to FIG. 1, in which the refracting device
2 according to the present invention is installed around the LCD
display 11 of digital camera 1. The LCD display 11 mainly is used
for immediately showing picture captured from lens 12, or showing
the pictures stored in memory card, or showing the settings of digital
camera 1. Thus display 11 is an object that the user has to view
when operating the digital camera.
[0014] As described above, display 11 has the deficiency of optical
dead-zone, that is, the image on the display will be invisible when
the visual angle of user is significantly slanted. Therefore, the
inventor utilizes a refracting device 2 and installs it on the LCD
display 11. The refracting device 2 at least includes: a frame 21,
a pair of opposite pivot bases 22, 22', and rotating arms 23, an
axle 24 which horizontally connects the rotating arms 23 and penetrates
and holds a reflecting plate 25, convex parts 251 provided at both
sides of reflecting plate 25 are used for locating when the refracting
device 2 is restored. The said reflecting plate 25 can be flipped
over and back to regenerate the image of display 11 on its mirror
face 250 to cater to the different visual angles and positions of
user. Thus the problem caused by optical dead-zone of LCD display
is solved, and the effective range of visual angle is significantly
increased.
[0015] To continue, referring to FIG. 2 and FIG. 3, at a multitudinous
scene (e.g., an exhibition, a press conference, or a show, and so
on.) or at the occasion that demands large view-finding angle, the
digital camera 1 has to be raised up or laid down, the user can
rotate reflecting plate 25 and adjust its angle through the operation
of rotating arm 23, to make the mirror face 250 of reflecting plate
25 precisely map to display 11. In this way, the effective range
of visual angle is significantly increased, the problem caused by
invisible LCD display is solved, and the user becomes less constrained
by the optical dead-zone.
[0016] Moreover, referring to FIG. 4, the refracting device 2 of
the present invention is further installed with a pair of track
bases 26, 26'. Sliding slots 260 are provided at both sides of the
track bases 26, 26'. The space of sliding slots 260 matches the
thickness of frame 21 of refracting device 2, such that the refracting
device 2 can be embedded into the sliding slot 260 of the track
bases 26, 26' to perform combination. The track bases 26, 26' are
provided to meet the need of commercially available digital cameras.
Referring to FIG. 5, the track bases 26, 26' can be fixed at both
sides on the display 11 of digital camera 1 to accept the embedment
of frame 21 of refracting device 2 and match the frame 21 to the
display 11. After adjusting the rotating arms 23, 24 upwards or
downwards, the mirror face 250 of reflecting plate 25 can precisely
map to the display 11, and the user can break through the constraint
of optical dead-zone. Therefore, Track bases 26, 26' are components
designed especially for the old-style or existing digital cameras.
[0017] By way of the structural design of the tracking bases 26,
26' and refracting device 2, the refracting device 2 becomes unlimited
by the installation. Consequently, the refracting device 2 can be
embedded into digital camera or other information appliances having
LCD display. |
