Patent ID: 8842194

Claim:
An imaging apparatus comprising: an image sensor that generates an image signal based on an incident light, the image sensor including a red color filter, a blue color filter, a first green color filter, and a second green color filter, the first green color filter having a peak spectral sensitivity in a longer wavelength region than a wavelength of a peak spectral sensitivity of the second green color filter; and a controller that corrects, according to an illuminance level of a subject, an image signal, that is generated by the image sensor through the first green color filter and the second green color filter, to generate a brightness signal, correcting the image signal with a first coefficient applied to the first green color filter and a second coefficient applied to the second green color filter, wherein the first coefficient applied to the first green color filter has a value decreasing as the illuminance level of the subject becomes low, and the second coefficient applied to the second green color filter has a value increasing as the illuminance level of the subject becomes low.
