Embodiment Construction
[0017] The embodiments described below are used in an image capture device with a flash, such as a digital camera. Fig. 1 is the flow chart of the first embodiment of flash lamp exciting method of the present invention, and this flow process comprises the following steps:
[0018] Step 12: Execute a focusing program of the image capture device to generate a focusing parameter;
[0019] Step 13: Estimate the shooting distance according to the focus parameter;
[0020] Step 14: Determine the excitation intensity of the flash according to the shooting distance; and
[0021] Step 15: When the image capture device captures the image, activate the flashlight according to the excitation intensity.
[0022] In step 12, the focus procedure is used to determine the focal length of the image capture device to obtain the best image resolution. The focusing parameter is generated when the focusing program is executed, and can be used for estimating the shooting distance in step 13 . In...
