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

Claim 9:
10. An image capture system for flash photography, comprising:
an image capture circuit, arranged to capture at least one first image under a first strobe intensity setting of main flash, and capture at least one second image under a second strobe intensity setting of the main flash, wherein the second strobe intensity setting is different from the first strobe intensity setting; and
a data processing circuit, arranged to generate an output image by blending the at least one first image and the at least one second image;
wherein before the at least one first image and the at least one second image are captured, the image capture circuit is further arranged to capture at least one third image under a third strobe intensity setting of pre-flash, and capture at least one fourth image under a fourth strobe intensity setting of the pre-flash, wherein the fourth strobe intensity setting is different from the third strobe intensity setting; and
the data processing circuit is further arranged to generate 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, and the data processing circuit is arranged to blend the at least one first image and the at least one second image according to the map.
