Abstract
Provided is an image processing system and a disparity calculation method. An image processing device included in the image processing system includes a preprocessor configured to determine an effective range of a focal length of an image sensor based on first disparities measured at a plurality of focal lengths of an object having a fixed position from the image sensor, and determine a representative value of equivalent aperture values for the image sensor corresponding to the effective range based on the first disparities. The image processing device also includes a disparity calculator configured to calculate a second disparity of the target object within the effective range based on the focal length, a first distance, a second distance, and the representative value of the equivalent aperture values.
