Abstract

The invention relates to a picture processing device which is used for conducting processing to output picture data to an external connection picture device. The picture processing device is provided with a picture drawing requirement receiver, a processing instruction generator, a coder and a transmitter. The picture drawing requirement receiver receives picture drawing requirements, the processing instruction generator is connected to the picture drawing requirement receiver and generates hardware processing instruction codes according to the picture drawing requirements, the coder is connected to the processing instruction generator and converts the hardware processing instruction codes into transmission data, and the transmitter is connected to the coder to transmit the transmission data to the external connection picture device through a transmission interface. The external connection picture device decodes the transmission data to obtain the hardware processing instruction codes and drives picture processing hardware of the external connection picture device to generate pictures according to the hardware processing instruction codes.

Description

technical field [0001] The present invention relates to an image processing device and an external image device, and in particular to an image processing device and an external image device capable of effectively transmitting image data and distributing calculation loads. Background technique [0002] There are many different electronic devices in today's life, most of which require the use of a display. Sometimes, for the sake of portability, the size of the display will be made smaller, such as a notebook computer, a tablet computer or a mobile phone for Internet access. However, the processing power of these devices is increasing day by day. As long as the appropriate output interface and external display are added, these devices can provide users with high-resolution images. [0003] The external display mentioned here includes common LCD screens, projectors or other devices capable of displaying images. Commonly used interfaces for connecting external displays includ...
