Imaging apparatus

An imaging apparatus comprising:

• a taking lens having a first region with a first characteristic and a second region with a second characteristic different from the first characteristic;
• an image pickup device having a first light-receiving element and a second light-receiving element two-dimensionally arranged;
• a light-shielding member which shields a light beam passing through the taking lens;
• and
• an image generating unit which generates an image of a subject from an imaging signal of the first light-receiving element or the second light-receiving element, wherein
• the light-shielding member is provided only to the first light-receiving element, and the light-shielding member provided only to the first light-receiving element performs light shielding so that a light beam passing through the second region does not enter the first light-receiving element, whereby only a light beam passing through the first region enters the first light-receiving element and the light beam passing through the first region and the light beam passing though the second region enter the second light-receiving element, and
• a ratio of the second region occupying an entire exit pupil of the taking lens is higher than a ratio of the first region occupying the entire exit pupil of the taking lens.
