    Abstract: An image sensor that provides a uniform sensitivity for pixels having color filters of the same color to increase the image quality is provided. The image sensor includes a substrate, a first grid pattern disposed on the substrate and including a first side wall and a second side wall opposite to the first side wall, a first pixel including a first photoelectric conversion element and a first color filter, and a second pixel including a second photoelectric conversion element and a second color filter. The first color filter contacts the first side wall and the second color filter contacts the second side wall. The first color filter and the second color filter are color filters of same color, and a first thickness of the first color filter is greater than a second thickness of the second color filter.

    Abstract: An image sensor may include a substrate which includes a plurality of block regions. Each block region may include a separate plurality of pixel regions. Each pixel region may include a separate photoelectric element of a plurality of photoelectric elements in the substrate and a separate micro lens of a plurality of micro lenses on the substrate. Each micro lens of the plurality of micro lenses may be laterally offset from a vertical centerline of the pixel region towards a center of the block region. Each block region of the plurality of block regions may include a common shifted shape of the plurality of micro lenses of the block region.

    Abstract: An image sensor in which a shading phenomenon is decreased and the quality is increased is provided. The image sensor includes a light-receiving region including a plurality of unit pixels. The image sensor further includes a first region with unit pixels adjacent to a center of the light-receiving region, and a second region with the unit pixels spaced apart from the center of the light-receiving region. In both regions, a plurality of color filters corresponding to the plurality of unit pixels is disposed on a first face of the substrate, as well as a grid pattern interposed between the plurality of color filters defining boundaries between the unit pixels. A width of the grid pattern in the second region is greater than a width of the grid pattern in the first region, thereby adjusting light receiving areas near the edge of the image sensor to correct for a shading phenomenon.
