Abstract

PURPOSE:To delete the picture information in a short time by deleting the corresponding picture information with selection of a retrieval code. CONSTITUTION:When the registered picture information is deleted, a retrieval code is first supplied through a keyboard 23. Then a CPU12 compares the retrieval code successively with the retrieval codes stored in a titled memory 18 and displays one or more coincident retrieval codes at a CRT display device 24. An operator performs the collective deletion or the sequential deletion. In the case of the sequential selection, the CPU12 reads a record address of the selected retrieval code out of the memory 18 and displays the relevant picture information to the device 24 via a display interface 17. Then the operator applies a deletion key after confirming the displayed picture information. When the deletion key is applied or the collective deletion is selected, the CPU12 stores the deletion code into the memory 18 or a corresponding retrieval data deletion code memory area A within a magnetic disk 28. Thus the picture information is deleted.

Next, the operation in such a configuration will be explained. first,
To explain the registration (recording) of image information, the user selects and sets the registration mode using the keyboard 23 and enters the search code for the image information to be registered. As a result, the CPU 12 checks the validity of the input data (cyclic redundancy check; CRC) based on the number of digits, character style, etc. according to the predefined search code format, and also checks the search codes that have already been registered. , check whether there is any double registration, etc., and if the search code is correct as a result of these checks, it will be stored in the main memo 3VC.

Then, set the original 21 on the two-dimensional scanning device 20, and
PUI2 is optical disk device 22 and two-dimensional scanning device 2
