Image processing system and method thereof

Abstract

An image processing system and method thereof for a digital camera are disclosed. The image processing system comprises a sweep control unit, a line extend control unit and a WOI control unit. When the output time of a digital image needs to be prolonged, the line extend control unit will be triggered in order to extend the processing time of the digital image.

Claims

1. An image processing system which provides a magnifying process for a digital image of a digital camera, the image processing system comprising: an image capturing unit that captures an original image and converts the original image into a digital image;an image control unit for executing an image conversion process, which converts the digital image into a pre-determined magnifying digital image and controls the processing sequence on the pre-determined magnifying digital image, the image control unit includes a sweep control unit for reducing the amount of horizontal data of the digital image, and produces the pre-determined magnifying digital image;an image magnification unit for magnifying the pre-determined magnifying digital image, and converting it into a magnified digital image;a temporary image storage unit for storing the magnified digital image; andan image displaying unit that displays the magnified digital image;wherein the image capturing unit, the image control unit, the image magnification unit, the temporary image storage unit and the image displaying unit are electronically coupled with each other.

2. The image processing system as claimed in claim 1, wherein the image control unit comprises: a line extension control unit used for controlling the output duration for each row of the digital image, enabling the generation of the pre-determined magnifying digital image.

3. The image processing system as claimed in claim 2, wherein the image control unit comprises: a Window of Interest (WOI) control unit for reducing the amount of vertical data of the digital image, enabling the generation of the pre-determined magnifying digital image.

4. The image processing system as claimed in claim 2, further comprising a control bus for controlling the line extension control unit.

5. An image processing method which provides a magnifying process for a digital image of a digital camera, the image processing method comprising the following steps: converting a digital image into a pre-determined magnifying digital image via an image converting process;converting the pre-determined magnifying digital image into a magnified digital image via an image magnification process; anddetermine if an extension on the output duration is required, and if the extension is required, the output of the pre-determined magnifying image will be delayed.

6. The image processing method as claimed in claim 5, wherein the image converting process further comprises the following step: reducing the amount of horizontal data of the digital image, to enable the generation of the pre-determined magnifying digital image.

7. The image processing method as claimed in claim 6, wherein the image converting process further comprises the following step: controlling the output duration for each row of the digital image, to enable the generation of the pre-determined magnifying digital image.

8. The image processing method as claimed in claim 7, wherein the image converting process further comprises the following step: reducing the amount of vertical data, to enable the generation of the pre-determined magnifying digital image.

9. The image processing method as claimed in claim 5, wherein the step of extending the output duration refers to the situation when the output of the magnified digital image induces the magnification process to experience insufficient processing time of magnifying the digital image, and requires delaying the output of the magnified digital image.
