Disclosed is a digital video camera performing white balance adjustment according to a photographing condition. The digital video camera with automatic exposure comprises an iris state detector for outputting an electrical signal with a predetermined magnitude corresponding to the status of an iris, a memory for saving a threshold value to be compared with the magnitude of the electrical signal, and a controller for comparing the magnitude of the electrical signal output from the iris state detector with the threshold value, determining the photographing condition after a predetermined determination time is elapsed, and adjusting the determination time according to the difference between the magnitude of the electrical signal and the threshold value.
