Embodiment Construction

[0015] Referring to FIG. 1 , it shows a functional block diagram of an image data playback system in a preferred embodiment of the present invention. The image data playing system 10 is used for playing image data, which includes an image data source device 100 and an image data playing device 200 . The image data playback device 200 includes a control unit 210 , a storage unit 220 , a transmission module 230 and a projection unit 240 . The image data playing device 200 may be, for example, a projector, a television, or a display. This embodiment uses a wireless projector as an example for illustration.

[0016] The control unit 210 sets an update center according to the current visual focus corresponding to the picture displayed in the display area, and divides the display area into at least a first sub-display area and a second sub-display area according to the update center. The first sub-display area may be a rectangle, and the second sub-display area may be a ring-shaped...

Abstract

A method for updating image data, for image data playing device, including the following steps: firstly, to confirm updating center of the display area according to the current vision focus corresponding to the displaying picture of the displaying area. Follow, the divide the display area into at least a first child display area and a second child display area according to the updating center which locates in the first child display area, the second child display area circles the first child display area. Then, to configure image data updating frequency of the first child display area and the second child display area. At last, to update the image data of the first child display area and the second child display area.

Description

technical field [0001] The present invention relates to an image data update method and a playback system using the method, and in particular to an image data update method capable of updating pictures in partitions and a playback system using the method. Background technique [0002] With the advancement of digital technology, various home appliances that originally needed to be connected by physical cables have produced various novel application methods due to the emergence of wireless networks. Since the traditional data transmission through cables is omitted, the placement of the data generation end (such as a computer) and the data playback end (such as a TV, projector, digital audio, etc.) can be more flexible, and the transmission distance is longer. At the same time, the visual beauty will not be damaged by messy data connection cables. [0003] At present, there are already wireless projector products on the market, which are realized by adding a wireless transmiss...
