ABSTRACT
A method and apparatus for changing operating modes in an
image capture device. The image capture device includes a
shutter button, a ?rst operating mode for capturing images,
and a second operating mode for displaying the captured
images on a display device. The method and apparatus
include providing the image capture device with two sets of
navigational control buttons, wherein a direction of image
scrolling on the display in the second operating mode is
mapped to the ?rst set of navigational control buttons. The
method and apparatus further include switching between the

BACKGROUND OF THE INVENTION
Most digital cameras today are similar in siZe to and

memory cards. Some digital cameras are also equipped With

Like the digital cameras described above, most digital
cameras suffer the disadvantage of forcing the user to change

mode before being able to capture another image. In cameras

LCD, most digital cameras operate in tWo modes, record and
play, although some cameras only have a record mode. In
record mode, the LCD is used as a vieW?nder in Which the
such as DSC-F1, this can be a cumbersome event, since the
user must press the lock button 13 While simultaneously

Besides the LCD, digital camera user interfaces also
include a number of buttons or sWitches for setting the

this type are the QV series by Casio Inc., of Dover, N]. The
QV series typically includes tWo navigation buttons labeled
“—” and “+”, a mode button, a display button, a Zoom button
and a delete button. Play mode for a QV camera begins With
a default screen displaying a full-siZed individual image. 35

camera interface Which correspond to each mode. But as
seen in FIGS. 1A and 1B, adding too many buttons to the
user interface may complicate the operability of the camera
since it forces the user to memoriZe too many button
functions and/or key sequences. Another disadvantage of
adding too many buttons to the user interface is that each
additional button increases the overall cost of the camera.

Referring to both FIGS. 5 and 8, When the camera is
play mode 606‘, the camera automatically sWitches to the
initially poWered in block 600, the camera defaults to the
capture mode 602. Thereafter, pressing the up button 411a

418 into the S2 position. After capturing the image, the user
can return the camera to revieW mode 604‘ or play mode 606‘

operate the digital camera.
Although the present invention has been described in
accordance With the embodiments shoWn, one of ordinary
skill in the art Will readily recogniZe that there could be
variations to the embodiments and those variations Would be

causes the camera to sWitch to play mode 606. Once in
revieW mode 604, pressing the up button 411 a on the
four-Way controller 409 causes the camera to sWitch to play
mode 606, and pressing the doWn button 411b causes the
camera to return to capture mode 602. When the camera is
in play mode 606, pressing the up button 411a on the
four-Way controller 409 causes the camera to sWitch to 25 eXample, the method and system may be implemented in
image capture devices having only tWo modes, but that have
multiple navigation screens Within the “play mode”

causes the camera to sWitch to play mode 606.
Accordingly, many modi?cations may be made by one of
ordinary skill in the art Without departing from the spirit and
scope of the appended claims.
What is claimed is:
1. A method for changing operating modes in an image
According to the present invention, since the user uses the
same mechanism for both image scrolling and mode
changes, the user can more quickly and intuitively change
from one mode to the neXt.
Although the above method of using the four-Way con
troller 409 to change operating modes alloWs a user to
capture device having a capture mode for capturing images
change modes more conveniently than prior methods Which

set of navigational control buttons; and
e) sWitching from the second and third modes to the

(FIG. 5).
Referring noW to FIG. 9, a state diagram of a method for
alloW a user to capture an image from both the capture

mode and the second and third modes.
2. The method of claim 1 Wherein the ?rst set of naviga
tional control buttons have a horiZontal orientation, and the
second set of navigational control buttons have a vertical
orientation.
3. The method of claim 2 further including the steps of
alloWs a user to capture an image from any operating mode.
As in the ?rst embodiment, When the camera is initially
poWered in block 600‘, the camera defaults to the capture
mode 602‘. Pressing the up button 411a on the four-Way
55
controller 409 causes the camera to sWitch to revieW mode
604‘, and pressing the doWn button 411b causes the camera
to sWitch to play mode 606‘. Pressing either the up button

pressing either the up button 411a or the doWn button 411b
While in play mode 606‘ causes the camera to sWitch to the
revieW mode 604‘.
Referring to FIGS. 5 and 9, While the camera is in either
the revieW mode 604‘ or play mode 606‘, the user may

device includes a shutter button for capturing images, the
method including the step of:
e) sWitching from the second mode to the ?rst mode When
the shutter button pressed, thereby alloWing a user to
capture an image from both the ?rst and second oper
ating modes.
