Abstract

A image data processing apparatus comprises: a user interface; an input device; a processor that converts original data; a first monitoring unit that monitors operation of the user interface or the input device; a second monitoring unit that monitors processing of the processor; a first storage unit that sequentially stores in chronological order at least one of operating records and processing records; an error detecting unit that detects an error; a second storage unit that, when an error is detected, stores determination information that includes a plurality of records that are stored in the first storage unit within a predetermined time period up until the error occurs; an error prediction unit that predicts occurrence of an error by determining whether there is agreement between the plurality of records and the determination information; and a process modifier that, when occurrence of an error is predicted, modifies the processing of the processor.

Claims

1. A data processing apparatus comprising:

a user interface that enables a user to input original data;

an input device that receives original data;

a processor that converts the original data input via the user interface or by the input device, so as to generate output data;

a first monitoring unit that monitors operation of the user interface or the input device;

a second monitoring unit that monitors processing of the processor;

a first storage unit that sequentially stores in chronological order at least one of the operating records representative of an operation history of a user and processing the records representative of a process sequence of the processor;

an error detecting unit that detects an error occurring in the second monitoring unit;

a second storage unit that, when an error is detected by the error detection unit, stores determination information that includes a plurality of records stored in the first storage unit within a predetermined time period up until the error occurs, the plurality of records being arranged in chronological order;

an error prediction unit that predicts occurrence of an error by determining whether there is agreement between the plurality of records sequentially stored in the first storage unit and the determination information stored in the second storage unit; and

a process modifier that, when occurrence of an error is predicted by the error prediction unit, modifies the processing of the processor so as to cause the processor to become noncompliant to the records included in the determination information,

wherein;

the processor is configured to perform interruption processing in which a first process is executed during execution of a second process; and

the process modifier is configured to determine whether a conflict between the first process and the second process occurs and, if the conflict occurs, adjust the interruption processing such that a time interval for the first process is formed and a time interval for the second process is formed.

2. The data processing apparatus according to claim 1,

wherein the processor is configured to perform processing on divided data obtained by dividing the original data, and

the process modifier adjusts processing timing of the processor, so as to restrict overlapping of two or more processes relating to the divided data.

3. The data processing apparatus according to claim 1, further comprising a timer, wherein:

each of the plurality of records includes time information obtained by the timer; and

the process modifier adjusts processing timing of the processor based on the time information.

4. A method of controlling a data processing apparatus including a user interface that enables a user to input original data;

an input device that receives original data; and

a processor that converts the original data input via the user interface or by the input device, so as to generate output data, the method comprising;

monitoring operation of the user interface or the input device;

monitoring processing of the processor;

sequentially storing in chronological order at least one of operating records representative of an operation history of a user and processing records representative of a process sequence of the processor;

detecting an error occurring in the processor;

storing, when an error is detected, determination information that includes a plurality of records that are stored within a predetermined time period up until the error occurs, the plurality of records being arranged in chronological order;

predicting occurrence of an error by determining whether there is agreement between the sequentially stored plurality of records and the stored determination;

information;

modifying, when occurrence of an error is predicted, the processing of the processor so as to cause the processor to become noncompliant to the records included in the determination information;

performing interruption processing in which a first process is executed during execution of a second process; and

determining whether a conflict between the first process and the second process occurs and, if the conflict occurs, adjusting the interruption processing such that a time interval for the first process is formed and a time interval for the second process is formed.

5. An image processing apparatus comprising:

a user interface that enables a user to input original image data;

an input device that receives original image data;

a processor that converts the original image data input via the user interface or by the input device, so as to generate output image data;

a first monitoring unit that monitors operation of the user interface or the input device;

a second monitoring unit that monitors processing of the processor;

a first storage unit that sequentially stores in chronological order at least one of operating records representative of an operation history of a user and processing records representative of a process sequence of the processor;

an error detecting unit that detects an error occurring in the second monitoring unit;

a second storage unit that, when an error is detected by the error detection unit, stores determination information that includes a plurality of records that are stored in the first storage unit within a predetermined time period up until the error occurs, the plurality of records being arranged in chronological order;

an error prediction unit that predicts occurrence of an error by determining whether there is agreement between the plurality of records sequentially stored in the first storage unit and the determination information stored in the second storage unit; and

a process modifier that, when occurrence of an error is predicted by the error prediction unit, modifies the processing of the processor so as to cause the processor to become noncompliant to the records included in the determination information,

wherein;

the processor is configured to perform interruption processing in which a first process is executed during execution of a second process; and

the process modifier is configured to determine whether a conflict between the first process and the second process occurs and, if the conflict occurs, adjust the interruption processing such that a time interval for the first process is formed and a time interval for the second process is formed.
