Solid-state image pickup element and image pickup device
View Patent ↗A solid-state image pickup element is disclosed which includes: a semiconductor substrate at which a plurality of element rows, in which a plurality of light-receiving elements are aligned along a vertical direction, are disposed in parallel along a horizontal direction; a plurality of color filters disposed in a predetermined color pattern at a light incident side of the semiconductor substrate; and a plurality of transfer paths transferring charge accumulated in the respective light-receiving elements of corresponding element rows. The sequence of lining-up in the horizontal direction of the element rows and the vertical transfer paths corresponding to the element rows at divisional regions, which are divided at a border line that runs along the vertical direction and includes a position corresponding to an optical axis of light incident from an optical unit on the semiconductor substrate, are opposite to one another. Also disclosed is an image pickup device using the solid-state image pickup element.
1. A solid-state image pickup element, comprising:
a substrate;
a plurality of light-receiving elements aligned in rows along a predetermined direction in the substrate, the light-receiving elements accumulating charge in accordance with an amount of received light;
a color filter provided at a light incident side of the substrate, the color filter having a predetermined color pattern, and transmitting light of a color component to each of the light-receiving elements;
a plurality of transfer paths disposed adjacent to the rows of light-receiving elements and transferring charge accumulated by respective light-receiving elements of corresponding element rows; and
a border that runs in a direction substantially parallel to the rows of light-receiving elements and includes a position corresponding to an optical axis of light incident from an image pickup lens disposed on the substrate, the border creating a left side region of the solid-state image pickup element and a right side region of the solid-state image pickup element;
wherein the transfer paths and rows of light-receiving elements are positioned such that accumulated charges in a light-receiving element row on the left side region of the solid-state image pickup element are read-out by a transfer path disposed to the left of the light-receiving element row, and accumulated charges in a light-receiving element row on the right side region of the solid-state image pickup element are read-out by a transfer path disposed to the right of the light-receiving element row.
2. The solid-state image pickup element of claim 1 , further comprising a charge separating layer that electrically separates the divisional regions along the border.
3. The solid-state image pickup element of claim 1 , further comprising a transfer path along the border which does not have a corresponding element row.
4. An image pickup device, comprising:
the solid-state image pickup element of claim 3 ;
a generating unit generating image data on the basis of the amount of the charge of the respective light-receiving elements, transferred from the solid-state image pickup element; and
a correcting unit carrying out correction which removes noise from the image data, on the basis of an amount of charge obtained from the transfer path which does not have a corresponding element row.
5. The solid-state image pickup element according to claim 1 , further comprising a pixel-separating layer positioned between a light-receiving element row and a transfer path, which will not read out the accumulated charge from that light-receiving element row.
6. The solid-state image pickup element according to claim 1 , wherein the plurality of light-receiving elements are arranged in a honeycomb form.
