Claims

First storage means for storing a first processing instruction relating to non-real-time video processing;
Second storage means for storing a second processing instruction relating to real-time video processing;
One of the first processing instruction stored in the first storage means and the second processing instruction stored in the second storage means is read, and non-real-time video processing is performed according to the first processing instruction. Instruction executing means for executing real-time video processing according to the second processing instruction;
The first processing instruction is stored in the first storage means and the second processing instruction is stored in the second storage means when the non-real-time video processing according to the first processing instruction is completed. And a command management unit that controls the command execution unit to execute the real-time video process according to the second command stored in the second storage unit.

The command management means sets the first processing command to the first processing command when the non-real-time video processing according to the first processing command is completed in a state set to give priority to the first processing command. When the second processing instruction is stored in the first storage means and the second processing instruction is stored in the second storage means, the non-real-time video processing is performed according to the first processing instruction stored in the first storage means. The video processing apparatus according to claim 1, wherein the instruction execution unit is controlled to execute the command.

The command management means has completed the non-real-time video processing according to one of the plurality of first processing commands related to a series of commands in a state set to give priority to the first processing command. When the remaining first processing instructions relating to the series of commands are stored in the first storage means and the second processing instructions are stored in the second storage means, the series of commands The execution of the second processing instruction stored in the second storage means is stopped until the non-real-time video processing according to the last processing instruction of the plurality of first processing instructions is completed, and the last processing After the non-real time video processing according to the command is completed, the command execution unit is configured to execute the real time video processing according to the second processing command stored in the second storage means. The video processing apparatus according to claim 2, characterized in that to control.

The non-real-time video processing is processing that does not require completion of processing for video signals for a predetermined period within a predetermined period, and the real-time video processing performs processing for video signals for the predetermined period for the predetermined period. The video processing apparatus according to claim 1, wherein the video processing apparatus needs to be completed.

2. The first storage means stores the first processing instruction set by the CPU, and the second storage means stores the second processing instruction set by the CPU. 5. The video processing apparatus according to any one of items 1 to 4.

When the non-real-time video processing according to the first processing instruction set by the CPU is completed, an interrupt signal is output to the CPU, and the first storage means is set by the CPU according to the interrupt signal The video processing apparatus according to claim 5, wherein a plurality of the first processing instructions are stored.

When the real-time video processing according to the second processing instruction set by the CPU is completed, an interrupt signal is output to the CPU, and the second storage means is set by the CPU according to the interrupt signal 6. The video processing apparatus according to claim 5, wherein one of the second processing instructions is stored.

Storing a first processing instruction relating to non-real-time video processing in a first storage means;
Storing a second processing instruction relating to real-time video processing in the second storage means;
One of the first processing instruction stored in the first storage means and the second processing instruction stored in the second storage means is read, and non-real-time video processing is performed according to the first processing instruction. An instruction execution step for executing real-time video processing in accordance with the second processing instruction;
The first processing instruction is stored in the first storage means and the second processing instruction is stored in the second storage means when the non-real-time video processing according to the first processing instruction is completed. And a command management step for controlling the command execution step so as to execute the real-time video processing according to the second command stored in the second storage means.

In the command management step, the first processing command is set to the first processing command when the non-real-time video processing according to the first processing command is completed in a state set to give priority to the first processing command.
