JPS5854486A - Image displaying system having variable density processing function - Google Patents

Abstract

PURPOSE:To obtain a smooth image and to realize an easy-to-see display, by applying a masking process to a binary coded image. CONSTITUTION:An enlarging circuit 1 enlarges a fed digital image and feeds it to a variable density processing circuit 2. The circuit 2 applies a masking process to the received image and delivers a new level value. A binary coding circuit 3 receives the new level value and binary codes it. The outputs of the circuits 3 and 2 are supplied to display parts 4 and 5 respectively to perform a binary display and a variable density display.

Description

[Detailed Description of the Invention] We are passionate about the image display method that has the ability of Honji, Kou & Furaishi, and for example, when displaying a binary image, we set a certain multi-value level to each element of this binary image. By applying Mask I&ll to this, - Add a chain plate level to the edge of the image to smooth it out, and display the jagged edge of the digital image so that it is easier to see. - to do.

Therefore, the m part of the 7th part of the ichigo, which is displayed in binary form on the register, has a jagged square shape. On the other hand, when the size of one stroke of a digital image is displayed at a rough 111 degrees, which is difficult for humans to discern, as in the case of rattan lugliness, If the jagged edge of this edge is not bothersome, it will be enlarged like a rattan 2B, and if the large *-g of one pixel becomes a thief, the existence of this jagged IP will cause iIgI
It becomes difficult to see ◎ (Kame 21ilt) 81 companies 8 times enlarged. Therefore, in order to avoid such jaggedness, conventionally, as shown in Figure l1k2, a large bevel (1jiii even when enlarged) was used. The raw size is the ill

It is the object of the present invention to provide an ms display method having a chain plate function that can be displayed so that the image appears as if the image is obtained. And for this reason, the present invention - forgiveness #l&! It has a double-image display method having 1lIIIAa and a mask m*'PR that displays a binary image as a mask I and a mask m*'PR that displays the mask I and a display means that displays the shoes 11111M outputted from the wrinkle mask armpit means, and displays the edges of the binary image.

EK Mototsuki The operation of the present invention will be explained.

This is treated with a 3 x "3 mask as shown in mSmfl). This mask round plate is inside the mask t-2 as shown in the figure.
Rank the level values of each ikI volume at a ratio of /2'4 to 4/24, and calculate the level value of each ikI in the ratio of 4/24 to 4/24.
This is a book by I (1, J) company O and is called Bell fIILM. tfm5kl (as shown in →), r24J and "0"
When there is a level value, the new level value is determined from 2/24 to 4/24 by using the current mask II and the 2/24 to 4/24 value. As shown in the new level value uj1611' of one of the parts (I・J)), Q such that < r14J, that is, general tF-, is
Let M be the previous level value of 111, J) in the center of the mask,

-...■ Then, a new level value shown in 6- is obtained by masking the image in Figure 114 based on the previous formula. Using this new level value, a new threshold is determined. When using a display section 1* that displays a binary value or a multi-value display, the 1iFr level value can be adjusted to a level of 9 to 9 depending on the display section. This can alleviate the jaggies in the 111 part. Based on Figures 7 to 11, an example of p # From the original image as shown by the 7-dotted line bIC in Figure 7, a digital 1iii image t- shown by the condensed line A is obtained. Then, this digital image ikl is multiplied by 3 and digitized as shown by the 8th- dotted line bIC. ′ value′ figure is obtained. However, this irises 8−
The binary figure shown in Figure 1 has large rough edges and is very difficult to see. □ ′ (b) - Therefore, if the "1" part of the 7 is level "24"', it will be enough like a striped 9 gang, and this - 3 x 3b mask as mentioned above! A
By flattening, 111 new level values such as stripes 1'0- are obtained. In this field 1G-, there are 4 omitted elements, except for one with a label of 124 in 91m'.

If you divide it and display it as r7, it will be divided into two values - ゛ and J
Comparing the iI8 and I8, it was found that the koji grains in Figure 8 were smoothed out, and moreover, an image closer to the Oi!iI image shown at 7mB was obtained.

This is what outputs the new level value.

Its detailed structure is shown in the 13th column. As shown in #1, there are two thinned outer layer circuits, a row shift register @, and 7. I1. Shift, @register 9.14), 11

It is possible to display an image as shown in -.

Of course, it is also possible to transmit the input name to the Chain Meal Processor 1lIial Connection 2 without using the input name, and display the same nine salts and display. The output of circuit 2 tSJi2 display m5t - can also be used to display the excessive room multivalue level 0 As explained above, according to the invention, the binarized image can be smoothed and displayed without the jaggedness t. Because it is cloudy,
It is possible to make it very easy to see. In addition to the above, another possible use of the present invention is to display the seal 7 isle on the hook.

Seal stamps at banks, etc. 1go 4 seals managed on a computer
It is desirable to file it as a binarized data and display it as necessary.

In such a case, as shown in the 14th branch, the customer's seal is retained as binary data, and when it is enlarged and displayed as shown in the same figure (→), the edges of the The image is enlarged and becomes very difficult to see.

Even if you compare it with the multi-level display (4-level display) from the 0 video, which makes the car very uncomfortable, the visibility is not much different.19. It can be seen that the display K (D is excellent).

As you can see from the above reading, by carefully displaying the binarized image of the original K station, it can be provided as a clear summary, so by doing it on a very easy-to-read display, it is possible to Although the case where the mineral display is displayed on the wrinkles is explained above, the present invention is not limited to this only.
The hook is also capable of producing a ringing sound on the vapor.
