Abstract: This application describes methods and systems for imbalance correction in quad image sensors. An exemplary method includes performing pixel value compensation at both inter-quaternion level and intra-quaternion level within a single pipeline. For example, the method may include obtaining an image captured by a quad image sensor and parameters of quaternions in the quad image sensor; computing a quad-pixel value bin and a standard deviation for each quaternion; performing inter-quad compensation among different quaternions using a cross-mean computed based on the plurality of pixel value bins and the plurality of standard deviations; computing texture weights for the plurality of quaternions based on the quad-pixel value bins; and performing intra-quad compensation among pixels within the quaternion based on the cross-mean and corresponding texture weight.
