Image sensor and digital camera

摘要

The present invention provides an image sensor that includes a plurality of light-receiving elements and a charge output component. The plurality of light-receiving elements are disposed inside the image sensor in a matrix arrangement corresponding to respective pixels. The light-receiving elements each includes a light-receiving surface at a front face and accumulates charge in accordance with light amounts received at the light-receiving surface. The charge output component outputs the charges accumulated at the plurality of light-receiving elements to outside the image sensor. The image sensor is configured to enable incidence of light on rear faces of the plurality of light-receiving elements. The plurality of light-receiving elements are capable of accumulating charges in accordance with light amounts received at the rear faces.
