Abstract
The present invention provides a digital camera that is capable of capturing a picture in which the brightness between a main subject and a nighttime background are well balanced. When an image capture instruction is received while a night scene portrait mode is set, in a pixel addition output mode, an image sensor 16 is set to a high sensitivity state by performing pixel addition, and outputs low resolution non-flash image data. Further, in an overall pixel output mode, the image sensor 16 outputs high resolution flash image data in a low sensitivity state without performing pixel addition. Next, a resolution conversion circuit 40 converts a resolution of non-flash image data to be equivalent to a resolution of flash image data. Then, an image combining circuit 60 adds respective pixel values of corresponding pixels in the non-flash image data and the flash image data having the same resolution and combines both sets of image data to generate image data for recording.
