Embodiment 1

[0046] figure 2 The structure of the electronic device provided by the first embodiment of the present invention is shown, and for the convenience of description, only the parts related to the embodiment of the present invention are shown.

[0047]The electronic equipment includes a decoding unit 1, connected with the decoding unit 1 to a first buffer 2 for buffering picture data, a second buffer 3 for buffering picture data, a display unit 4, a screen 5 and to the decoding unit 1 and the first buffer 2. The processor 6 for coordinating and controlling the second cache 3 and the display unit 4 . Wherein the size of the first cache 2 and the second cache 3 is different, the size of the first cache unit 2 is set to the size of the picture data that can be displayed on the screen in a ratio of 1:1, that is, a picture that is the same as the resolution of the screen The size of the image data. The size of the second cache unit 3 is smaller than the size of the first cache unit ...

Embodiment 2

[0054] image 3 It shows the implementation process of the method for displaying picture data in the electronic device provided by the first embodiment of the present invention, wherein the structure of the electronic device is as follows figure 2 As shown, the details are as follows:

[0055] In step S101, the electronic device is initialized, the output end of the decoding unit in the electronic device is connected to the first buffer, and the input end of the display unit is connected to the first buffer.

[0056] In the embodiment of the present invention, the electronic device is first initialized, the output end of the decoding unit in the electronic device is connected to the first buffer, and the input end of the display unit is connected to the first buffer, so that the decoding unit decodes The picture data in the first cache is cached in the first cache, so that the display unit displays the picture data in the first cache on the screen. At this time, since the s...

Embodiment 3

[0066] Figure 4 It shows the implementation process of the method for displaying picture data in the electronic device provided by the second embodiment of the present invention. The electronic device is such as figure 2 As shown, the details are as follows:

[0067] In step S201, the electronic device is initialized, the output terminal of the decoding unit in the electronic device is connected to the first buffer, and the input terminal of the display unit is connected to the first buffer.

[0068] In step S202, the decoding unit decodes the picture data, outputs the decoded picture data to the first buffer, and displays the picture data in the first buffer on the screen through the display unit.

[0069] In step S203, the image data in the first cache is reduced, and the reduced image data is transferred to the second cache.

[0070] In step S204, when the next picture data is to be displayed, switch the input terminal of the display unit of the electronic device to the...

Abstract

The invention is suitable for the field of image treatment, providing an electronic device and a method and a system for displaying image data. The electronic device comprises a decoding unit, a displaying unit, a first cache and a second cache. The method comprises the following steps: lessening the image data in the first cache and transferring the lessened image data to the second cache for storage; switching the input end of the displaying unit of the electronic device to the second cache, and displaying the image data in the second cache on a screen through the displaying unit; decoding the next image data by the decoding unit and outputting the decoded image data to the first cache; and switching the input end of the displaying unit to the first cache, and displaying the image data in the first cache on the screen. The embodiment of the invention uses memories with different sizes to achieve the display of the image data, which can save the memories for displaying the image data, and reducing the cost of the electronic device while providing the clear image data.

Description

technical field [0001] The invention belongs to the field of picture processing, and in particular relates to an electronic device and a display method and system for picture data. Background technique [0002] At present, electronic devices, such as multimedia players (such as MP3 / MP4 / PMP), digital photo frames (DPF), pico projectors (Pico Projector), etc., all have the function of decoding and displaying image data. see figure 1 , is a schematic structural diagram of a picture data display device in an electronic device provided in the prior art, including a decoding unit, two buffers of the same size (marked as buffer 1 and buffer 2 respectively), a display unit and a screen. The size of the two caches with the same size is related to the resolution of the screen. Generally, the size of the two caches with the same size is the size of a picture data with the same resolution as the screen. The steps for displaying picture data by using the picture data display device are...
