A computer model for correcting the spatial distortion in images acquired with a high‐speed image converter camera is described. The distortion is caused by electrodynamic interaction of the photoelectric currents within the image converter camera, and appears as an inward bowing of the individual high‐speed images. The model is implemented in a postprocessing algorithm, using the pixel values in an image to infer the interacting photoelectric currents and thus allow computation of the distorting force acting on each pixel. The force is converted into a corrective translation using three system parameters which are determined by analyzing images for which the predistortion geometry is known. Measurements on a variety of test images show the model removes up to 85% of the image converter distortion.
