Image processing apparatus, method for controlling the same, and computer-readable storage medium

An image processing apparatus capable of executing a plurality of image processes in a first execution environment for executing a program described in a first programming language and a second execution environment for executing a program described in a second programming language, the apparatus comprising:

• a memory device that stores a set of instructions;
• and
• at least one processor that executes the set of instructions to:
• in a case where execution of a new image process by a first application described in the first programming language is requested during execution of image processes in the first execution environment, search for a first application capable of executing the new image process;
• obtain a memory usage when the new image process by the first application is executed, which is held together with the searched first application, and memory usages of the respective image processes already running in the first execution environment;
• compare a total memory usage obtained from the obtained memory usages of the respective image processes and the memory usage when the requested new image process is executed, with an allowable memory capacity representing a memory usage allowed to be used in the first execution environment;
• and
• in a case where the total memory usage does not exceed the allowable memory capacity as a result of the comparison, execute the new image process, and in a case where the total memory usage exceeds the allowable memory capacity, notify a request source of an error representing that the new image process cannot be executed owing to an insufficient memory, without executing the new image process.

A method for controlling an image processing apparatus capable of executing a plurality of image processes by one or more plugin application, the method comprising:

• in a case where execution of a new image process by a plugin application is requested during execution of image processes by a plugin application, searching for a plugin application capable of executing the new image process;
• obtaining a memory usage when the new image process by the plugin application is executed, which is held together with the searched plugin application, and memory usages of the respective image processes already running by the plugin application;
• comparing a total memory usage obtained from the obtained memory usages of the respective image processes and the memory usage when the requested new image process is executed, with an allowable memory capacity representing a memory usage allowed to be used in a process of executing the plugin application;
• and
• in a case where the total memory usage does not exceed the allowable memory capacity as a result of the comparison, executing the new image process, and in a case where the total memory usage exceeds the allowable memory capacity, notifying a request source of an error representing that the new image process cannot be executed owing to an insufficient memory, without executing the new image process.
