Assignee: MEDIATEK INC.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 0:
1. An image capture method for flash photography, comprising:
capturing at least one first image while a strobe device is operating under a first strobe intensity setting for emitting main flash;
capturing at least one second image while the strobe device is operating under a second strobe intensity setting, wherein the second strobe intensity setting is different from the first strobe intensity setting; and
generating an output image by blending the at least one first image and the at least one second image;
before the at least one first image and the at least one second image are captured:
capturing at least one third image while the strobe device is operating under a third strobe intensity setting for emitting pre-flash;
capturing at least one fourth image while the strobe device is operating under a fourth strobe intensity setting, wherein the fourth strobe intensity setting is different from the third strobe intensity setting; and
generating a map according to image statistics of the at least one third image and image statistics of the at least one fourth image, wherein the map records image characteristics at different pixel locations;

wherein generating the output image by blending the at least one first image and the at least one second image comprises:
blending the at least one first image and the at least one second image according to the map.
