Image processing apparatus and image processing method are provided. The image processing apparatus may include an image sensor having a plurality of photodetectors and include a 3D image calculating module. The image sensor may be configured to generate a first set of input information at a first time/first location and a second set of input information at a second time/second location, where the first set of input information may be associated with a first weighting value, and the second set of input information may be associated with a second weighting value. The 3D image calculating module may be configured to generate output information based on the first and the second sets of input information and the first and the second weighting values, wherein at least one of the plurality of photodetectors includes germanium.
