An imaging apparatus comprising: an imaging device including: a plurality of directive pixel output units that each receive incident light from an imaging target entering without intervention of any of an imaging lens and a pinhole, and output a detection signal in response thereto, wherein a respective light shielding film covers a part of each directive pixel output unit, thereby independently setting, for each directive pixel output unit, an incident angle directivity indicative of a variation in sensitivity of the directive pixel output unit with respect to an incident angle of the incident light, and a non-directive pixel output unit that receives the incident light entering without the intervention of any of an imaging lens and a pinhole and does not have a light shielding film for providing the incident angle directivity; a restoration section configured to create and solve a plurality of simultaneous equations in order to calculate pixel values of a plurality of pixels configuring an image of the imaging target, wherein the simultaneous equations are created by modelling the imaging target as a plurality of point light sources, each simultaneous equation equating the detection signal output by a respective directive pixel output unit as a sum of products, each product being that of a light intensity of a respective point light source and a coefficient indicating the incident light directivity of the respective directive pixel output unit to an incident angle of incident light received at the respective directive pixel output unit from the respective point light source, wherein solving the simultaneous equations yields values of the light intensities of the point light sources, the pixel values being calculated based on the yielded values; and an exposure controlling section configured to perform exposure control of the plurality of directive pixel output units on a basis of a non-directive detection signal that is a detection signal outputted from the non-directive pixel output unit. a plurality of directive pixel output units that each receive incident light from an imaging target entering without intervention of any of an imaging lens and a pinhole, and output a detection signal in response thereto, wherein a respective light shielding film covers a part of each directive pixel output unit, thereby independently setting, for each directive pixel output unit, an incident angle directivity indicative of a variation in sensitivity of the directive pixel output unit with respect to an incident angle of the incident light, and a non-directive pixel output unit that receives the incident light entering without the intervention of any of an imaging lens and a pinhole and does not have a light shielding film for providing the incident angle directivity; a restoration section configured to create and solve a plurality of simultaneous equations in order to calculate pixel values of a plurality of pixels configuring an image of the imaging target, wherein the simultaneous equations are created by modelling the imaging target as a plurality of point light sources, each simultaneous equation equating the detection signal output by a respective directive pixel output unit as a sum of products, each product being that of a light intensity of a respective point light source and a coefficient indicating the incident light directivity of the respective directive pixel output unit to an incident angle of incident light received at the respective directive pixel output unit from the respective point light source, wherein solving the simultaneous equations yields values of the light intensities of the point light sources, the pixel values being calculated based on the yielded values; and an exposure controlling section configured to perform exposure control of the plurality of directive pixel output units on a basis of a non-directive detection signal that is a detection signal outputted from the non-directive pixel output unit. <EOS>
