Abstract

A mode identifying method of identifying a mode to which inputted code data belongs is provided. An inherent code existing in each mode so as to have a probability-manner relation and the probability-manner relation are stored so as to correspond to each other. A code which coincides with the inherent code stored is extracted from the code data and the number of coincidence times of every code is counted. The mode to which the code data belongs is identified on the basis of the number of coincidence times obtained by the counting step and the probability-manner relation stored by applying a multi-value logical relation or a fuzzy logical relation or both of a fuzzy rule and a fuzzy inference to the number of coincidence times obtained and probability-manner relation stored.

Claims

1. An apparatus having a plurality of programs for interpreting input code data and generating image information from the interpreted code data, said apparatus comprising:

determining means for determining whether a first value is equal to or greater than a prescribed threshold, the first value being obtained by dividing a second value indicating the number of first codes, in the input code data, inherent in a first program by a third value for normalizing the second value; and

identifying means for identifying the first program as a program for interpreting the input code data in response to a determination by said determining means that the first value is equal to or greater than the prescribed threshold.

2. An apparatus according to claim 1, wherein the third value is obtained from the product of an appearance frequency probability of the first code in the input code data and the number of code data used for the identification.

3. An apparatus having a plurality of programs for interpreting input code data and generating image information from the interpreted code data, said apparatus comprising:

determining means for determining whether a first value is equal to or greater than a prescribed threshold, the first value being obtained by multiplying a second value by a third value, the second value being obtained by dividing a fourth value indicating the number of first codes, in the input code data, inherent in a small number of programs including a first program by a fifth value for normalizing the fourth value, the third value being obtained by dividing a sixth value indicating the number of second codes, in the input code data, inherent in a small number of programs including the first program by a seventh value for normalizing the sixth value; and

identifying means for identifying the first program as a program for interpreting the input code data in response to a determination by said determining means that the first value is equal to or greater than the prescribed threshold.

4. An apparatus according to claim 3, wherein the fifth value is obtained from the product of an appearance frequency probability of the first code in the input code data and the number of code data used for the identification.

5. An apparatus according to claim 3, wherein the seventh value is obtained from the product of an appearance frequency probability of the second code in the input code data and the number of code data used for the identification.

6. A method carried out in an apparatus having a plurality of programs for interpreting input code data and generating image information from the interpreted code data, said method comprising the steps of:

determining whether a first value is equal to or greater than a prescribed threshold, the first value being obtained by dividing a second value indicating the number of first codes, in the input code data, inherent in a first program by a third value for normalizing the second value; and

identifying the first program as a program for interpreting the input code data in response to a determination in said determining step that the first value is equal to or greater than the prescribed threshold.

7. A method according to claim 6, wherein the third value is obtained from the product of an appearance frequency probability of the first code in the input code data and the number of code data used for the identification.

8. A method carried out in an apparatus having a plurality of programs for interpreting input code data and generating image information from the interpreted code data, said method comprising the steps of:

determining whether a first value is equal to or greater than a prescribed threshold, the first value being obtained by multiplying a second value by a third value, the second value being obtained by dividing a fourth value indicating the number of first codes, in the input code data, inherent in a small number of programs including a first program by a fifth value for normalizing the fourth value, the third value being obtained by dividing a sixth value indicating the number of second codes, in the input code data, inherent in a small number of programs including the first program by a seventh value for normalizing the sixth value; and

identifying the first program as a program for interpreting the input code data in response to a determination in said determining step that the first value is equal to or greater than the prescribed threshold.

9. A method according to claim 8, further comprising obtaining the fifth value from the product of an appearance frequency probability of the first code in the input code data and the number of code data used for the identification.

10. A method according to claim 8, further comprising obtaining the seventh value from the product of an appearance frequency probability of the second code in the input code data and the number of code data used for the identification.

11. A storage medium for storing a program executed in an apparatus having a plurality of programs for interpreting input code data and generating image information from the interpreted code data, with the program comprising the steps of:

determining whether a first value is equal to or greater than a prescribed threshold, the first value being obtained by dividing a second value indicating the number of first codes, in the input code data, inherent in a first program by a third value for normalizing the second value; and

identifying the first program as a program for interpreting the input code data in response to a determination in said determining step that the first value is equal to or greater than the prescribed threshold.

12. A storage medium according to claim 11, wherein the third value is obtained from the product of an appearance frequency probability of the first code in the input code data and the number of code data used for the identification.

13. A storage medium for storing a program executed in an apparatus having a plurality of programs for interpreting input code data and generating image information from the interpreted code data, with the program comprising the steps of:

determining whether a first value is equal to or greater than a prescribed threshold, the first value being obtained by multiplying a second value by a third value, the second value being obtainedby dividing a fourth value indicating the number of first codes, in the input code data, inherent in a small number of programs including a first program by a fifth value for normalizing the fourth value, the third value being obtained by dividing a sixth value indicating the number of second codes, in the input coded data, inherent in a small number of programs including the first program by a seventh value for normalizing the sixth value; and

identifying the first program as a program for interpreting the input code data in response to a determination in said determining step that the first value is equal to or greater than the prescribed threshold.

14. A storage medium according to claim 13, wherein the fifth value is obtained from the product of an appearance frequency probability of the first code in the input code data and the number of code data used for the identification.

15. A storage medium according to claim 13, wherein the seventh value is obtained from the product of an appearance frequency probability of the second code in the input code data and the number of code data used for the identification.
