Image capturing device with touch screen for adjusting camera settings

An electronic device, comprising:

• a digital image capture unit;
• a multi-point touch sensitive screen coupled to the digital image capture unit, wherein the screen is for displaying an image and receiving a multi-point touch selection of a region on the screen;
• and
• a processing system coupled to the screen, wherein the processing system is configured to:
• detect a multi-touch input from the screen;
• define selected region based on the multi-touch input;
• monitor, automatically, pixel brightness in the selected region for each of one or more images captured by the digital image capture unit and
• determine, based on the monitored pixel brightness, whether a scene being captured by the digital image capture unit has changed;
• and
• adjust, automatically, at least one exposure parameter while the scene remains unchanged.

A non-transitory machine readable medium storing a program for execution by at least one processing unit of an electronic device, the electronic device having a built-in image capture device and a display screen for displaying captured images, the program comprising sets of instructions for:

• receiving a multi-touch input from a display screen of an image capture device;
• identifying, in response to the multi-touch input, a selected region with an exposure metering area on the display screen;
• monitoring pixel brightness, in the exposure metering area, of one or more images captured by the image capture device in order to determine at least one exposure parameter for the image capture device;
• determining, based on the monitored pixel brightness, whether a scene being captured by the image capture device has changed;
• and
• automatically adjusting at least one exposure parameter while the scene has not changed.
