Image capturing device with touch screen for adjusting camera settings

摘要

Several methods for operating a built-in digital camera of a portable, handheld electronic device are described. In one embodiment, the device receives a user selection (e.g., tap, tap and hold, gesture) of a region displayed on the display screen (e.g., touch sensitive screen). A touch to focus mode may then be initiated in response to the user selection and exposure and focus parameters determined and adjusted. Then, an automatic scene detection mechanism can determine whether a scene has changed. If the scene has changed, then the touch to focus mode ends and a default automatic focus mode initiates. This mode sets a new exposure metering area and focus area prior to determining and adjusting exposure and focus parameters, respectively.

1. A method to capture digital images, the method comprising:
receiving a multi-touch input from a display screen of an image capture device; identifying, in response to the multi-touch input, a first selected region; adjusting the first selected region to a second selected region in response to a change in the received multi-touch input; defining a first focus area based on the second selected region; automatically monitoring pixel brightness in a portion in each of one or more images captured by the image capture device, the portion is based on the first focus area; and automatically adjusting at least one exposure parameter of the image capture device based on the monitored pixel brightness.
