Problems solved by technology
This scheme has the following disadvantages: 1) because the processing speed of the central processing unit equipped on the mobile device is relatively low, when the graphics image is zoomed, it often takes a long time, which will bring problems to the user. Inconvenience such as operation delay
2) Because the central processing unit on the mobile device also needs to run other service programs at the same time, such as the mobile phone also needs to communicate with the base station or transmit data at the same time, when the central processing unit runs the program of zooming graphics and images, it will affect other services. In severe cases, some critical services will fail
3) Since the memory on the mobile device is generally relatively small, if in addition to accommodating the operating system and other necessary service programs and data, it is also necessary to store the program for zooming and zooming the graphic image and the processed graphic image, this will cause memory loss. tense conflict
4) Because in the process that central processing unit is running zoom graphics image program, central processing unit will constantly read program instructions and image data to be processed from internal memory by bus interface and write processing result back internal memory, cause The power consumption is greatly increased, and the mobile device is mainly powered by the built-in battery, so the continuous working time of the battery will be greatly shortened

Embodiment Construction
[0014] Referring to Fig. 1, in the mobile device capable of zooming graphics and images in the prior art, the central processing unit 1 will constantly read the program instructions and the image data to be processed from the memory 3 through the bus interface and write the processing results back The internal memory 3, because the internal memory 3 stores the program of zooming in and out and the processed image, so the contradiction of memory tension will be brought. The power supply 2 supplies power to the above functional modules.
[0015] Referring to Fig. 2, a kind of mobile equipment that can carry out video scaling to graphic image, comprises central processing unit 1, memory 3 and the battery 2 that supplies power for other functional modules, and described memory 3 stores operating system, program and data, and described The central processing unit 1 reads the graphic image data to be processed from the memory 3 through the system bus interface and writes the process...

The invention discloses a kind of moving device which can carry on video scaling to the graph and image, which belongs to moving device field for displaying graph and image. The invention can reduce and enlarge the graph and image, and won't increase the burden of the centre processor, and the consumption of the device. The centre processor reads the data of graph and image from the inner memory through the system bus interface and writs the result back into the inner memory. The invention also includes scaling process model of graph and image, the centre processor sends the data of the graph and image, and the corresponding parameter related to the scaling to the process model, the model process the data according to the parameters and returns the result data to the centre processor.
Description
technical field [0001] The invention relates to the field of mobile equipment capable of displaying graphic images, in particular to the field of mobile equipment capable of performing video scaling on graphic images. Background technique [0002] In existing mobile devices capable of displaying graphic images, zooming in or out of a graphic or image is mainly realized by running a corresponding program on the central processing unit carried in the mobile device. This scheme has the following disadvantages: 1) because the processing speed of the central processing unit equipped on the mobile device is relatively low, when the graphics image is zoomed, it often takes a long time, which will bring problems to the user. Inconvenience such as operation delay. 2) Because the central processing unit on the mobile device also needs to run other service programs at the same time, such as the mobile phone also needs to communicate with the base station or transmit data at the same t...
