    Abstract: An image sensor includes a sensing layer, a number of filter units, and a grid structure. The filter units are disposed on the sensing layer. The grid structure is disposed on the sensing layer and surrounding each of the filter units. The grid structure includes a first partition wall disposed on the sensing layer and located between two adjacent filter units, and a second partition wall disposed on the first partition wall located between the two adjacent filter units. The refractive index of the first partition wall is less than the refractive index of the second partition wall.

    Abstract: A color correction device for an image sensor is provided. The image sensor is divided into regions. The color correction device includes a quantum efficiency (QE) measurement circuit, an addressing circuit, and a correction circuit. The QE measurement circuit generates a color signal according to a sensing signal from each pixel of the image sensor. The addressing circuit receives the color signal corresponding to each pixel, obtains a location of each pixel on the image sensor, and averages all of the color signals corresponding to the pixels whose locations are disposed in one of the regions to obtain an average color signal. The correction circuit receives the average color signal to obtain a color correction matrix of the one of the regions and corrects the color signals of the pixels whose locations are in the one of the regions by the color correction matrix.

    Abstract: An image sensor package includes a medium layer having a first surface and a second surface opposite to the first surface. The image sensor package also includes a metal-insulator-metal structure disposed on the first surface of the medium layer. The metal-insulator-metal structure includes a first metal layer, a first insulating layer, and a second metal layer, and the first insulating layer is disposed between the first metal layer and the second metal layer. The image sensor package further includes an optical filter disposed on the second surface of the medium layer.
