摘要： The present invention provides an image sensing module including an image sensing device and a calculation device. The image sensing device includes a plurality of pixels for acquiring an operation image containing an object image. The calculation device stores a look-up table regarding a temperature related parameter and a position deviation of the object image at each pixel associated with the temperature related parameter, and selects a deformation error from the look-up table according to the temperature related parameter corresponding to the operation image so as to correct a current position of the object image in the operation image.
