Patent ID: 8760529

Claim:
A solid-state image sensor comprising: a pixel array including a plurality of pixels that are arranged in columns and rows; a plurality of read signal lines, each of which is connected to a number of pixels that are arranged in a row direction; a plurality of output signal lines, each of which is connected to a number of pixels that are arranged in a column direction; and a color filter array which defines the color components of light rays to be incident on the plurality of pixels, wherein in the pixel array, first pixel groups, each of which is made up of a plurality of pixels that captures an image in a first exposure time, and second pixel groups, each of which is made up of a plurality of pixels that captures an image in a second exposure time that is shorter than the first exposure time, are alternately arranged in either the row direction or the column direction, each of the first and second pixel groups being made up of pixels that are arranged in one row and L columns (where L is an integer that is equal to or greater than two), and wherein the plurality of read signal lines are classified into a first type of read signal lines that are connected to the first pixel groups and a second type of read signal lines that are connected to the second pixel groups, each said read signal line of the first type being connected to the first pixel group that is located on a row that is adjacent to the read signal line on one side and to the first pixel group that is located on a row that is adjacent to the read signal line on the other side, each said read signal line of the second type being connected to the second pixel group that is located on a row that is adjacent to the read signal line on one side and to the second pixel group that is located on a row that is adjacent to the read signal line on the other side, and wherein the color filter array makes light rays with mutually different color components incident on a number of pixels that are included in each said first pixel group and also makes light rays with mutually different color components incident on a number of pixels that are included in each said second pixel group.
