Abstract
An image sensor may have an array of image sensor pixels having varying light collecting areas. The light collecting area of each image pixel may vary with respect to other image pixels due to varied microlens sizes and varied color filter element sizes throughout the array. The light collecting area may vary within unit pixel cells and the variability of the light collecting areas of pixels within each pixel cell may depend on the location of the pixel cell in the pixel array. Each unit pixel cell may include at least one clear pixel having a light collecting area that is smaller than the light collecting areas of other single color pixels in the unit pixel cell.
