Abstract: This application describes method and apparatus for HDR+ using M×N-cell sensors. An example apparatus includes a plurality of pixel groups, each pixel group having M×N pixels configured with color filters of a same color such that the M×N pixels in each pixel group capture a same color. M and N are integers greater than one, and each pixel is represented by a first number of bits. The example apparatus further include one or more processors configured to: capture, through the plurality of pixel groups, a plurality of frames of a scene using a short-exposure setting; merge the plurality of frames into an HDR image; and perform tone mapping on the HDR image to reduce a dynamic range of the super-pixels of the HDR image into a low dynamic range (LDR) image, wherein each pixel in the LDR image is represented with the first number of bits.
