An image processing system includes a defect correction system that identifies defective regions of a digital image using a defect map. The defect map is automatically created from an input image device. The defect correction system corrects the defective regions of the digital image using the non-defective regions of the digital image in accordance with various correction routines.

A picture transmission system comprising: a coding apparatus receiving a series of pictures, coding each picture in said series with reference to a preceding picture in said series, transmitting resulting coded data on a communication link, receiving from said communication link an error signal specifying a part of one of said pictures in which a decoding error occurred, selecting a picture in said series affected by said decoding error as a reference picture, modifying a part of said reference picture affected by said decoding error to obtain a first modified reference picture, and coding a subsequent picture in said series, following said reference picture, with reference to said first modified reference picture; and a decoding apparatus receiving said coded data from said communication link, decoding said coded data to reproduce said series of pictures, temporarily storing each decoded picture in said series for reference in decoding a further picture in said series, detecting said decoding error, transmitting said error signal over said communication link to said coding apparatus, selecting the reference picture also selected by said coding apparatus, modifying said part of said reference picture after decoding said reference picture, as said reference picture was modified by said coding apparatus, thereby obtaining a second modified reference picture, and decoding said subsequent picture with reference to said second modified reference picture. 14. The picture transmission system of claim 13, wherein said decoding apparatus transmits said error signal to said coding apparatus repeatedly. 15. The picture transmission of claim 14, wherein said coding apparatus, after receiving said error signal once, ignores further repetitions of said error signal. 16. The picture transmission system of claim 13, wherein said coding apparatus sends information to said decoding apparatus, notifying said decoding apparatus that said coding apparatus has modified said reference picture, and said decoding apparatus selects said reference picture according to the information received from said coding apparatus. 17. The picture transmission system of claim 16, wherein said coding apparatus sends said information to said decoding apparatus repeatedly. 18. The picture transmission of claim 17, wherein said decoding apparatus, after receiving said information once, ignores further repetitions of said information. 19. The picture transmission system of claim 13, wherein said coding apparatus and said decoding apparatus both modify said part of said reference picture by using another part of said reference picture. 20. The picture transmission system of claim 13, wherein said coding apparatus and said decoding apparatus both modify said part of said reference picture by using a corresponding part of a picture preceding said reference picture in said series. 21. The picture transmission system of claim 13, wherein said decoding error occurs in a first picture previous to said reference picture in said series. 22. The picture transmission system of claim 21, wherein said decoding apparatus, after decoding said first picture to obtain a first decoded picture, modifies said first decoded picture by using data unaffected by said decoding error to replace data affected by said coding error, then modifies each further decoded picture in said series affected by propagation of said decoding error, by using data unaffected by said decoding error to replace data affected by propagation of said coding error, until said reference picture has been modified. 23. The picture transmission system of claim 22, wherein said coding apparatus temporarily stores a plurality of said pictures, from said first picture to said reference picture, and modifies
