Abstract
An image sensor in accordance with an embodiment of the present invention includes a pixel array configured to include a plurality of pixels corresponding to a plurality of rows and a plurality of columns that include one or more first column groups and one or more second column groups and are disposed in a direction crossing the plurality of rows and a data sampling unit configured to sample pixel data of a first column group of a first row and to sample pixel data of a second column group of a second row, wherein the first column group and the second column group are alternatively arranged.
Claims25
An image sensor comprising:
- a pixel array configured to include a plurality of pixels corresponding to a plurality of rows and a plurality of columns that include one or more first column groups and one or more second column groups and are disposed in a direction crossing the plurality of rows;
- and
- a data sampling unit configured to sample pixel data of a first column group of a first row and to sample pixel data of a second column group of a second row,
- wherein the first column group and the second column group are alternatively arranged.
The image sensor of claim wherein the data sampling unit samples the pixel data of the first column group of the first row in a period in which the first row is selected and the pixel data of the second column group of the second row in a period in which the second row is selected.
The image sensor of claim wherein the first and second rows are adjacent to each other among rows having the same pixel patterns as each other in the pixel array.
A method of operating an image sensor including a plurality of pixels corresponding to a plurality of rows and a plurality of columns where include one or more first column groups and one or more second column groups and are disposed in a direction crossing the plurality of rows, the method comprising:
- sampling pixel data of a first column group of a first row in the pixel array;
- and
- sampling pixel data of the second column group where are alternatively arranged with the first column group.
