Imaging apparatus and imaging method

A method comprising:

• outputting, by an image sensor, a first signal indicating light intensity received by a plurality of phase pixels of a plurality of pixels;
• conducting, by a first adjuster, gain adjustment on the plurality of phase pixels according to the first signal;
• increasing, by the first adjuster, gain of a second phase pixel of the plurality of phase pixels when light intensity received by the second phase pixel is lower than a predetermined range according to the first signal;
• and
• adjusting, by an auto-focuser, a focal point of an image according to a second signal, the second signal being outputted by the plurality of phase pixels after the gain adjustment;
• generating and outputting, by a compensator, a compensation signal indicating light intensity received by the plurality of phase pixels according to signals outputted by the plurality of pixels;
• determining exposure and gain, by a second adjuster, for capturing the image according to the signals outputted by the plurality of pixels and applying the exposure and the gain to the plurality of pixels;
• and
• inputting, by an image processor, both the compensation signal and the signals output from the plurality of pixels on which the exposure and the gain were applied and generating image data.

• conducting, by a first adjuster, gain adjustment on the plurality of phase pixels according to the first signal;
• conducting, by the first adjuster, gain adjustment of a plurality of local pixels of the plurality of pixels, the plurality of local pixels neighboring the plurality of phase pixels;
• reducing, by the first adjuster, gain of a first phase pixel of the plurality of phase pixels and gain of a first local pixel of the plurality of local pixels when the first adjuster detects saturation of the first phase pixel according to the first signal;
