Abstract

An apparatus for image processing includes an image sensor including a pixel array of a plurality of pixels, the pixel array having equal vertical and horizontal lengths; a buffer storing image signals scanned at the image sensor; and a controller reading out the image signals stored in the buffer according to a gradient of the image sensor with respect to a reference direction set to a predetermined value on an X-Y plane.

Claims

1. An apparatus for image processing, the apparatus comprising:

an image sensor comprising a pixel array of a plurality of pixels, the pixel array having equal vertical and horizontal lengths;

a buffer storing image signals scanned at the image sensor; and

a controller reading out the image signals stored in the buffer according to a gradient of the image sensor with respect to a reference direction set to a predetermined value on an X-Y plane.

2. The apparatus of claim 1, wherein the image sensor is rotatable on the X-Y plane.

3. The apparatus of claim 1, wherein the image sensor performs scanning with a start pixel and a scanning direction fixed, the start pixel being a pixel from which the scanning begins in the pixel array.

4. The apparatus of claim 1, wherein the buffer stores the image signals in a scanning order of the image sensor.

5. The apparatus of claim 1, wherein the controller comprises:

a gradient determination unit determining a gradient of the image sensor; and

an operation unit reading out the image signals stored in the buffer according to the gradient.

6. The apparatus of claim 5, wherein the operation unit rotates the image signals stored in the buffer by the gradient of the image sensor, and reads out the image signals stored in the buffer according to an aspect ratio of a display device that displays an image.

7. The apparatus of claim 6, wherein the operation unit comprises an offset control part selecting a portion of the image signals stored in the buffer such that an image being displayed on the display device corresponds with the aspect ratio of the display device.

8. The apparatus of claim 7, wherein the aspect ratio of the display device is 4:

3.

9. The apparatus of claim 5, wherein the operation unit changes a read-out direction in which the image signals stored in the buffer are read out, according to the gradient of the image sensor.
