## Abstract

Provided is an image processing device capable of an image processing with using a general-purpose image processing hardware in accordance with video input without mediation of a CPU. The image processing device includes: a storage medium for storing an image data acquired by video inputting unit for acquiring video images; a CPU for a general processing; image processing unit for processing the image data stored in the storage medium; setting unit for determining a processing content of the image processing unit; a command list indicating an order of setting and activating the image processing unit; and command writing unit for setting and activating the image processing unit based on the command list in synchronization with input of the image data from the video inputting unit without mediation of the CPU.

## Claims

### Claim at position 1

1-6 (canceled)

### Claim 7

An image processing semiconductor device comprising:
a central processing unit (CPU);
an image processing unit for processing video image data acquired by a video inputting unit and stored in a storage unit; and
a command writing unit for activating the image processing unit in response to receiving a notification from the video inputting unit that the acquisition of the video image data is complete,
wherein the CPU does not receive the notification from the video inputting unit that the acquisition of the video image data is complete.

### Claim 8

An image processing device comprising:
a storage unit for storing video image data acquired by a video inputting unit;
a central processing unit (CPU);
an image processing unit for processing the video image data stored in the storage unit, the image processing unit including a setting unit for determining a processing content of the image processing unit; and
a command writing unit for setting and activating the image processing unit based on a synchronization signal, received from the video inputting unit, indicating that the acquisition of the video image data is complete,
wherein the CPU does not receive the synchronization signal from the video inputting unit indicating that the acquisition of the video image data is complete.

### Claim 9

A method for image processing, comprising:
providing a central processing unit (CPU), an image processing unit, and a command writing unit;
processing, with the image processing unit, video image data acquired by a video inputting unit and stored in a storage unit; and
operating the command writing unit to activate the image processing unit in response to receiving a notification from the video inputting unit that the acquisition of the video image data is complete,
wherein the CPU does not receive the notification from the video inputting unit that the acquisition of the video image data is complete.

### Claim 10

A method for image processing, comprising:
providing a storage unit, a central processing unit (CPU), an image processing unit having a setting unit, and a command writing unit, storing, in the storage unit, video image data acquired by a video inputting unit;
processing, with the image processing unit, the video image data stored in the storage unit, the setting unit determining a processing content of the image processing unit; and
operating the command writing unit to set and activate the image processing unit based on a synchronization signal, received from the video inputting unit, indicating that the acquisition of the video image data is complete,
wherein the CPU does not receive the synchronization signal from the video inputting unit indicating that the acquisition of the video image data is complete.
