发明名称 IMAGE BRIGHTNESS COMPENSATION METHOD AND DIGITAL CAMERA DEVICE WITH IMAGE BRIGHTNESS COMPENSATION FUNCTION
摘要 An image brightness compensation method and a digital camera device with an image brightness compensation function are suitable for adjusting a brightness of a digital image shot by a digital camera device, especially when the shot object is located outside a maximum output range of a flash lamp. The method includes the steps of pre-capturing a target image, and recording target information; triggering a flash lamp, and meanwhile capturing a raw image; determining whether the raw image satisfies a brightness threshold or not according to a brightness difference between the target information and the raw image; if the raw image fails to satisfy the brightness threshold, executing a brightness compensation program on the raw image according to the target information; and finally, generating an output image.
