An image pickup apparatus includes an image sensor in which main and auxiliary pixels are bidimensionally arranged for outputting a high and a low output signal, respectively. The user of the camera is allowed to select a desire image quality mode appearing on a monitor by operating a control panel. In a dynamic range priority mode, the high and low output signals are smoothly combined with each other to produce an image signal with a broadened dynamic range. In a resolution priority mode, the high and low output signals are not combined in order to guarantee resolution. In a sensitivity priority mode, the low output signal is added to the high output signal in order to raise the saturation point of the first output signal and therefore sensitivity. Further, in a color reproducibility priority mode, a white balance correcting method is changed depending upon the color temperature of a scene.
