MULTIPLE LENS IMAGING APPARATUSES, AND METHODS AND PROGRAMS FOR SETTING EXPOSURE OF MULTIPLE LENS IMAGING APPARATUSES
First Claim
1. A multiple lens imaging apparatus comprising:
- a plurality of imaging unit for obtaining images by photography; and
exposure setting unit for using an exposure value calculated according to a result of photometric measurement for predetermined main imaging unit among the plurality of imaging unit, to set exposure of the main imaging unit and sub-imaging unit other than the main imaging unit, wherein,in the case where the number of the sub-imaging unit having obtained saturated images in photography by setting the exposure thereof according to the exposure value is larger than one, if the saturated images include an image saturated on a high luminance side and an image saturated on a low luminance side, the exposure setting unit calculates the exposure value separately for the sub-imaging unit having obtained the image saturated on the high luminance side and for the sub-imaging unit having obtained the image saturated on the low luminance side.

Abstract
When an exposure value calculated according to a result of photometric measurement for predetermined main imaging units among a plurality of imaging units is used for setting exposure of the main imaging units and sub-imaging units other than the main imaging units, judgment is carried out as to whether an image or images obtained in photography with the sub-imaging units by setting the exposure thereof according to the exposure value is/are saturated. In the case where a result of the judgment is affirmative, any one of the sub-imaging units having obtained the saturated image or images is designated as new main imaging units. The exposure value is calculated newly, and the exposure is set for the new main imaging units and for new sub-imaging units other than the new main imaging units.
