Title: Mail sorter
Inventor: WATANABE SHIGERU
IPC: G06K9/62
Filed: 2001-01-18
Abstract: PROBLEM TO BE SOLVED: To reduce any erroneous sorting caused by address recognition processing in a mail sorter. SOLUTION: The picture of the address face of a mail is fetched by picture fetching processing (101), and the fetched picture is stored in picture storage processing (103), and the first address recognition is operated by address recognition processing (102) by using the fetched picture. Then, sorting control processing 1(104) instructs temporary sorting (105) according to the recognized result, and when any recognized result is not detected, the sorting control processing 1 (104) instructs video coding processing (106) to perform video coding using the stored picture, and when the recognized result is detected, the sorting control processing 1(104) instructs address re-recognition processing (107) to perform re-recognition using the stored picture.  When the re-recognized result is different from the first recognized result, the address re-recognition processing (107) judges that erroneous reading is generated, and instructs the video coding processing (106) to perform the video coding. Sorting control processing 2(108) operates re-sorting (109) by adding the correction of the result of the video coding based on the result of the address recognition processing (102).
