Imaging device camera system and driving method of the same

An imaging device comprising a pixel array on a substrate in which a plurality of pixels are arranged in an array, the plurality of pixels configured to convert light into electric signals, said plurality of pixels comprising a plurality of color pixels and at least one clear pixel, wherein:

• the plurality of color pixels include at least two of (i) a first color pixel with a first filter effective to cause the first color pixel to have a peak spectral sensitivity for red light, (ii) a second color pixel with a second filter effective to cause the second color pixel to have a peak spectral sensitivity for blue light, or (iii) a third color pixel with a third filter effective to cause the third color pixel to have a peak spectral sensitivity for green light;
• the clear pixel has a fourth filter effective to cause the clear pixel to have a high transmittance to white light;
• the plurality of pixels include respective micro lenses disposed at light incident sides of the pixels;
• the first, second, third color filters are each thicker in a depth direction of the pixels than the fourth filter;
• and
• the clear pixel is adjacent one of the plurality of color pixels.
