Method and apparatus for reducing shutter lag in a digital imaging device
First Claim
Patent Images
1. A method of reducing shutter lag, comprising:
- at a time before an indication that a photograph is to be taken imminently, selecting at least one capture parameter of a digital imaging device when it is determined that the digital imaging device is substantially still; and
locking the capture parameter so long as the digital imaging device remains substantially still.

Abstract
A digital imaging device, such as a digital camera, minimizes shutter lag by determining some capture parameters, such as focus and exposure settings, before a user of the device has indicated that a photograph is to be taken. The parameters are updated when the device becomes substantially still before the indication that a photograph is to be taken.

10. A digital imaging device, comprising:
-
a shutter button having an S1 position and an S2 position;
memory; and
logic, the logic configured to sense motion of the digital imaging device before S1 is reached;
determine, based on the sensed motion, that the digital imaging device is substantially still;
select at least one capture parameter upon determining that the digital imaging device is substantially still; and
store in the memory an indication that the at least one capture parameter has been selected. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A digital camera, comprising:
-
an electronic array light sensor;
a lens that projects an image of a scene onto the electronic array light sensor;
a shutter button having and S1 and an S2 position;
logic, the logic configured to, before the S1 position is reached, sense motion of the camera;
perform automatic focus of the lens when it is determined, based on the sensed motion, that the camera is substantially still; and
re-perform automatic focus only upon a determination that the camera has moved since automatic focus was last performed and that the camera has once again become substantially still. - View Dependent Claims (19, 20)
