Problems solved by technology

[0007] However, because the manufacturing cost of the integrated circuit 113 is relatively high, it is the primary goal of cost control (cost down) measures for manufacturers who want to reduce the manufacturing cost of digital data prompters; moreover, for general users That is to say, only one output signal will be used at a time, and it is rare to use two methods of VGA signal and VIDEO signal for display at the same time.

Embodiment Construction

[0035] The specific implementation of the digital data prompt machine and its control method that generates a group of outputs at the same time of the present invention will be described in detail below with reference to the accompanying drawings. see figure 2 , which is a schematic block diagram of the output circuit of the digital data prompting machine proposed by the present invention. In the figure, the output end of the digital data prompter includes at least a scaler 211 , a digital / analog converter (DAC) 212 , and a video signal converter 213 .

[0036] In the architecture of the output circuit of the digital data prompting machine of the present invention, the frequency of the signal processed by the image converter 211 is controlled at about 50Hz / 60Hz or 75Hz (except for 75Hz, the actual signal frequency can also be 60, 70, 75, or 85Hz, which can be adjusted freely depending on the scope of application), and then the signal is transferred to the subsequent digital / a...

Abstract

The invention is concerned with the reminder and the controlling method that only create a group of output digital data, the reminder includes at least one image converter, the controlling method includes the following steps: control a frequency of the output signal by the converter; based on the signal, the digital data reminder only output one of a VGA (video graphics array) signal or a video signal at the same time. The invention not only can decrease the production cost, but also improve the shortage of the existing technology.

Description

technical field [0001] The present invention refers to a digital data prompting machine and its control method, especially to a digital data prompting machine and its control method which only produces one set of outputs at the same time. Background technique [0002] Digital data prompt machine (Visualizer) is a multi-functional device that can convert any image, such as photos, positive and negative films, slides, and even 3D objects, into digitized images after a simple connection. The data. [0003] Please refer to FIG. 1( a ), which is a schematic block diagram of the input and output of the existing digital data prompting machine. Wherein, the digital data prompt machine 11 is to receive a charge-coupled device (Charge-CoupledDevice, CCD) signal and a video graphics array (Video Graphics Array, VGA) signal sent by a personal computer 12, and simultaneously produce a first output and A second output is sent to a display device 13 . [0004] Please refer to FIG. 1( b ...
