Abstract

According to the present invention, a color screen which is generally used is a display method applied to a display method by an ultrasonic diagnostic apparatus. By selecting the plane memory in which the data of the mode is stored and reading and processing only the data of the plane memory, the time required for data processing is reduced, the memory capacity for data processing is reduced, and various modes can be changed more quickly. have.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display method of an ultrasonic diagnostic apparatus, and more particularly, to a signal display method for displaying data in various modes of an ultrasonic diagnostic apparatus using a VGA (Video Graphics Array) for processing and displaying color data.

In general, as a personal computer (hereinafter referred to as a PC) is commercialized, various graphic adapters have been developed to provide a better graphic environment. Recently, VGA is widely used among various graphic adapters. Normally, the total video memory of the VGA we are using has a size of 256KB to 1MB, and the CPU can read only 64KB of area. Therefore, in order to use a larger capacity video memory with an address area of 64 KB, a method of constructing and processing a memory in units of 64 KB is used. At this time, a 64KB memory unit is called a memory plane. The VGA consists of four memory planes as shown in FIG. 1 in 16 color mode. Color information of one pixel of the screen is represented as 4-bit data obtained by collecting one bit from each memory plane of four memory planes. As such, when the screen is composed of four memory planes, the color data of each pixel is 4 bits, and thus 16 colors can be displayed. In this display method, when the color image of the screen changes, all data of four planes must be processed simultaneously. That is, as shown in FIG. 2, four memory planes constituting one screen are stored in the first to fourth memory planes 21, 22, 23, and 24, respectively, and the color of the screen is displayed. When the image changes, the first to fourth buffers 25, 26, 27, and 28 coupled to the output terminals of the four plane memories are enabled as predetermined active signals ACT1 to ACT4 are simultaneously applied, thereby providing a first To color data stored in the fourth memory planes 21, 22, 23, and 24 are simultaneously output to the data storage memory 29. As such, the color data of the color screen is composed of four memory planes, and in the data processing for display, all data of the four memory planes are processed at the same time.

The present invention uses a conventional color display method for displaying and configuring one screen into four memory planes. The display method is applied to the display method of an ultrasonic diagnostic apparatus. In the conventional display method, four memory planes are used to obtain color data. However, in the display method of the ultrasonic diagnostic apparatus according to the present invention, since the screen is not displayed in color, different planes are used for each memory plane instead of the conventional color concept. The concept of displaying data with the concept of bit (0 or 1) is introduced.

Accordingly, an object of the present invention is to change the program library and to process only data of a memory plane whose image changes among various memory planes in displaying data of various modes on the screen by using an ultrasonic diagnostic device, thereby improving data processing speed and data storage. The present invention provides a display method capable of reducing the required memory capacity and enabling faster mode switching.

An object of the present invention is to store a variety of modes to be displayed for each memory plane, and to select a memory plane corresponding to a desired mode to be changed among the various modes. And a step of processing the data of the selected memory plane according to the data processing of the mode.

Hereinafter, preferred embodiments of the present invention will be described in detail. First, as described above, in the case of four memory planes of one screen, by changing the program library, each memory plane represents data of different modes. For example, the first memory plane represents text characters input by the user as the first mode, the second memory plane represents various graphic information as the second mode, and the third memory plane has a mark as the third mode. The moving area is allocated and shown, and the fourth memory plane shows other miscellaneous information as the fourth mode. Therefore, since four memory planes are displayed on the screen at the same time, the four modes allocated to each memory plane are displayed at the same time. At this time, when the output image of any one of the four modes displayed changes, only the data of the memory plane corresponding to the mode need be processed.

In the present invention, as shown in FIG. 2 by changing the program library, four different modes of data are stored in the first to fourth memory planes 21, 22, 23, and 24, respectively. For example, when the scan image of the first mode is changed while the data of the above four modes are being displayed, the predetermined active signals ACT1-ACT4 are assigned to the first to fourth buffers 25, 26, and 27. 28 is activated to activate only the first memory plane 21 of the four memory planes 21, 22, 23, and 24. Then, only data of the first mode stored in the first plane memory 21 is transferred to the data storage memory 29 to perform data processing.

As such, when the image of the screen changes, the four plane memories do not process all the data at the same time and display a new screen as in the conventional case. The capacity can be reduced and the mode change can be performed more quickly because the data processing time of each mode is shorter.
