Abstract

An image signal process apparatus and a method for controlling thereof are provided. The image signal process apparatus includes a storage unit storing pixel data of an incoming frame image, a scaling filter generating one frame image by scaling the pixel data, and a controller retrieving a part of the pixel data among pixel data of the frame image stored at the storage unit, and transmitting the retrieved pixel data to the scaling filter. As a result, a process of processing a stereoscopic image may be reduced such that deterioration of an image quality may be prevented, and a data processing time may be reduced.

Claims

1. An image signal process apparatus comprising:

a storage unit which stores pixel data of an incoming frame image;

a scaling filter which generates one frame image by scaling the pixel data; and

a controller which retrieves a part of the pixel data among pixel data of the frame image stored at the storage unit, and transmits the retrieved pixel data to the scaling filter.

2. The image signal process apparatus of claim 1, wherein the controller retrieves the remaining pixel data among pixel data of the frame image stored at the storage unit and transmits the retrieved remaining pixel data to the scaling filter, and the scaling filter generates another frame image by scaling the remaining pixel data.

3. The image signal process apparatus of claim 1, wherein the incoming frame image is a stereoscopic image which comprises a left frame image and a right frame image.

4. The image signal process apparatus of claim 3, wherein the part of the pixel data retrieved by the controller constitutes one of the left frame image and the right frame image.

5. The image signal process apparatus of claim 3, wherein the controller retrieves the pixel data of the right frame image, after retrieving the pixel data of the left frame image and transmits the retrieved pixel data to the scaling unit.

6. The image signal process apparatus of claim 1, wherein the controller groups the pixel data stored at the storage unit, and retrieves the grouped pixel data in an alternate order.

7. A method for controlling an image signal process apparatus comprising:

storing pixel data of an incoming frame image;

retrieving a part of the pixel data among the stored pixel data of the frame image; and

generating one frame image by scaling the retrieved part of the pixel data.

8. The method of claim 7, wherein the retrieving retrieves the remaining pixel data among the stored pixel data of the frame image, and the generating the frame generates another frame image by scaling the retrieved remaining pixel data.

9. The method of claim 7, wherein the incoming frame image is a stereoscopic image which comprises a left frame image and a right frame image.

10. The method of claim 9, wherein the retrieved part of the pixel data constitutes one of the left frame image and the right frame image.

11. The method of claim 9, wherein the retrieving retrieves the pixel data of the right frame image, after retrieving the pixel data of the left frame image and the generating the frame generates a frame by scaling the retrieved left frame image and generates another frame by scaling the retrieved right frame image.

12. The method of claim 7, wherein the retrieving groups the pixel data, and retrieves the grouped pixel data in an alternate order.
