Image display system and method

The present invention relates to an image processing system, and more particularly to an image scaling processing system and method for a mobile device.

At present, mobile devices with image display functions such as mobile phones, PDAs, and handheld game consoles have become very popular. When using these products, consumers sometimes zoom in on the displayed images through buttons, touch screens, etc. To meet different requirements, however, with the development of technology, people hope to improve these technologies to make the image display function of such products more flexible, intelligent and user-friendly.

In view of the above, it is necessary to provide an image display system and method that can more easily scale an image of a mobile device.

An image display system includes a mobile device, at least one acceleration sensor, and an image processing unit, wherein the at least one acceleration sensor is configured to sense an acceleration of the mobile device and convert the acceleration of the mobile device into a displacement Data, the displacement data indicates a direction and a displacement amount of the mobile device, and the image processing unit is configured to receive the displacement data, and perform an immediate scaling process on the image of the mobile device according to the displacement data.

An image display method includes the following steps: a mobile device displays an image; an acceleration sensor senses the acceleration of the mobile device, and converts the acceleration of the mobile device into displacement data, the displacement data indicates a direction and a displacement amount of the mobile device; and an image The processing unit receives the displacement data, and performs an immediate scaling process on the image of the mobile device according to the displacement data.

The image display system and method can sense the distance between the mobile device and the user by sensing the acceleration of the mobile device to select a corresponding zoom factor, so that the use of the mobile device is more convenient and flexible.

Figure 4 is a flow chart showing a second preferred embodiment of the image display method of the present invention.

Referring to FIG. 1, a preferred embodiment of the image display system 1 of the present invention includes a mobile device 12, an acceleration sensor 14, and an image processing unit 16.

The mobile device 12 is configured to display images including, but not limited to, a mobile phone, a palmtop computer, a handheld game console, etc., and the image display system 1 is configured to perform scaling processing on the image displayed by the mobile device 12.

The acceleration sensor 14 can be disposed in the mobile device 12 or on an outer surface of the mobile device. The acceleration sensor 14 is configured to sense an acceleration of the mobile device 12 and The acceleration of the mobile device 12 is converted to displacement data, which may represent the direction and amount of displacement of the mobile device 12. The measurement of the displacement of the mobile device 12 by using the acceleration sensor 14 is a conventional technique and will not be described herein.

The image processing unit 16 is coupled to the acceleration sensor 14 to receive the displacement data and perform an immediate scaling process on the image of the mobile device 12 based on the displacement data. The image processing unit 16 is equivalent to the function of the conventional mobile device to perform image scaling through the button control image processing unit, that is, the image processing unit 16 controls image scaling according to the received displacement data in the present invention. The image processing unit in the mobile device controls the image scaling based on the received button signal.

In this embodiment, when it is known that the mobile device 12 is moving away from the user, the image processing unit 16 zooms out the image displayed by the mobile device 12, so that the image displayed by the mobile device 12 is displayed. The image processing unit 16 zooms in on the image displayed by the mobile device 12 when it is known that the mobile device 12 is moving in the direction of the user. At this time, the user can Observing the details of the image displayed by the mobile device 12, and the larger the value of the amount of movement indicated by the displacement data, the larger the zoom factor of the image displayed by the mobile device 12. In addition, the user can set a maximum magnification and a maximum reduction factor through the image processing unit 16, when the zoom ratio of the image displayed by the mobile device 12 reaches the maximum magnification or the maximum reduction multiple, even if the user makes the movement When the device 12 continues to move in the direction of the user or away from the user, the image displayed by the mobile device 12 does not change.

Referring to FIG. 2 together, the preferred embodiment of the image display system 2 of the present invention further includes a mode selection unit 11. The image processing unit 16 stores a plurality of image display modes, each image display mode having an image resolution and a corresponding image zoom ratio number. The mode selection unit 11 is connected to the image processing unit 16, and the user can select an image display mode to play an image through the mode selection unit 11, for example, when the user selects the highest supported by the mobile device 12. The resolution image display mode, when the mobile device 12 starts to work, its displayed image is reduced to a minimum, at this time, even if the acceleration sensor 14 senses that the mobile device 12 is facing away The direction of the user has an acceleration, and the image displayed by the mobile device 12 can no longer be reduced. Similarly, if the user selects an image display mode that is lower than the maximum resolution supported by the mobile device 12, then the motion sensor 14 senses the mobile device 12 after the mobile device 12 starts working. With an acceleration in a direction away from the user, the image displayed by the mobile device 12 is reduced.

Referring to FIG. 3, a first preferred embodiment of the image display method of the mobile device of the present invention is used in the image display system 1, which includes the following steps:

Step S11: The mobile device 12 displays an image.

Step S12: The acceleration sensor 14 senses the acceleration of the mobile device 12, and converts the acceleration of the mobile device 12 into displacement data, and the displacement data indicates the direction and displacement of the mobile device.

Step S13: The image processing unit 16 receives the displacement data, and performs an immediate scaling process on the image of the mobile device according to the displacement data.

Referring to FIG. 4, a second preferred embodiment of the image display method of the mobile device of the present invention is used in the image display system 2, which includes the following steps:

Step S21: The mode selection unit 11 selects a preset image display mode from the image processing unit 16 to cause the mobile device 12 to display an image in the preset image display mode.

Step S22: the acceleration sensor 14 senses the acceleration of the mobile device 12, and converts the acceleration of the mobile device 12 into displacement data, the displacement data indicating the direction and displacement of the mobile device 12;
