Method for capturing an image with an electronic handheld device
View Patent ↗A method for capturing an image with an electronic handheld device ( 1 ) equipped with a camera unit ( 2 ) and capture means ( 3 ) for triggering an image capture, said electronic handheld device ( 1 ) further comprising power supplying means ( 4 ) connected to said camera unit, and at least one additional component ( 5 ) also connected to said power supplying means ( 4 ) through a DC/DC converter ( 11 ), said method comprising a first step (B) for detecting actuation of capture means ( 3 ), and a second step (C) for capturing image once actuation of capture means has been detected. According to the invention, said method further comprises an intermediate step (D) for switching said DC/DC converter ( 11 ) off for at least the duration of the second step (C).
1. Method for capturing an image with an electronic handheld device equipped with a camera unit and capture means for triggering an image capture, said electronic handheld device further comprising power supplying means connected to said camera unit, and at least one additional component also connected to said power supplying means through a DC/DC converter, said method comprising:
a first step for detecting actuation of capture means; and
a second step for capturing image once actuation of capture means has been detected, wherein said method further comprises an intermediate step for switching said DC/DC converter off for at least the duration of the second step.
2. Method according to claim 1 , further comprising an end step for switching said DC/DC converter on once an image has been captured.
3. Method according to claim 1 , wherein said electronic handheld device also include radio communication means periodically activated for communication with a cellular network, wherein said method further comprises a step for detecting a communication activity, and for delaying said intermediate step until said communication activity ends.
4. Method according to claim 1 , wherein said electronic handheld device also include a display, wherein images can be previewed on said display at least until the beginning of said intermediate step.
5. Method according to claim 1 , wherein said at least additional component is a backlight display driver, or a backlight keypad driver, or a flash driver.
