In an imaging apparatus adding image signals output from a sensor array which receives a light flux through an optical system and performs photoelectric conversion thereon, the sensor array being arranged a plurality of light receiving elements two-dimensionally, the imaging apparatus includes a pixel adding unit that divides the light receiving elements on the sensor array into a plurality of groups with a region including predetermined types of pixels as a group unit, and that adds, for each of the types of pixels, image signals output from the pixels included in four of the groups which are positioned “n” groups away from each other on the sensor array. |

1. A digital camera comprising:
an image sensor, the image sensor being arranged with:
i) in order of a first light receiving element, a second light receiving element, a third light receiving element and a fourth light receiving element along a first direction, in which the first light receiving element outputs a first signal corresponding to light made incident through a first filter having a first spectral characteristic, the second light receiving element outputs a second signal corresponding to light made incident through a second filter having the first spectral characteristic, the third light receiving element outputs a third signal corresponding to light made incident through a third filter having the first spectral characteristic, and the fourth light receiving element outputs a fourth signal corresponding to light made incident through a fourth filter having the first spectral characteristic;ii) in order of the first light receiving element, a fifth light receiving element, and a six light receiving element along a second direction perpendicular to the first direction, in which the fifth light receiving element outputs a fifth signal corresponding to light made incident through a fifth filter having the first spectral characteristic and the sixth light receiving element outputs a sixth signal corresponding to light made incident through a sixth filter having the first spectral characteristic, andiii) in order of the second light receiving element, a seventh light receiving element, and an eighth light receiving element along the second direction, in which the seventh light receiving element outputs a seventh signal corresponding to light made incident through a seventh filter having the first spectral characteristic and the eighth light receiving element outputs a eighth signal corresponding to light made incident through an eighth filter having the first spectral characteristic; an adding unit inputting the first signal, the second signal, the third signal, the fourth signal, the fifth signal, the sixth signal, the seventh signal and the eighth signal, and generating i) a first addition signal by adding the first signal, the third signal and the sixth signal, and ii) a second addition signal by adding the second signal, the fourth signal and the eighth signal, and a displaying unit displaying an image generated by the first addition signal and the second addition signal obtained by the adding unit. |
