Beschreibung
Zusammenfassung:	A disclosed apparatus includes an image sensor, an LED flash driver, and image adjustment logic, operatively coupled to an LED flash driver. The image adjustment logic is operative to detect a flash driving current level produced by the LED flash driver and to adjust an image captured using the image sensor, in response to the flash driving current level. In one embodiment, the image adjustment logic may access a lookup table to obtain an image adjustment corresponding to a detected flash driving current level. The image adjustment logic is operative to adjust the image processing pipeline, the image sensor, or both, in response to the flash driving current level.
