Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to an image data input processing device, and more particularly, to a technology for inputting data from an image scanner.

(Prior Art) Conventionally, when image data is input from an image scanner, a configuration as shown in FIG. 2 or 3 is generally adopted.

First, FIG. 2 shows a configuration that is mainly used when using a handy scanner that traces over an image by hand.

Data from the image scanner 1 is stored in a display memory (bitmap memory) 2 and sequentially displayed on a display device 3.

Further, the data in the display memory 2 is encoded by the encoding circuit 4 and stored in the encoded data storage memory 5.

- According to the input processing device having this configuration, since the human power data from the scanner 1 is displayed sequentially, there is an advantage that the human power image can be confirmed quickly.

However, a drawback is that if the number of manually generated pixels is greater than that of the display device 3, only the entire image cannot be displayed.

Next, FIG. 3 shows a configuration mainly used when a stationary high-definition scanner is used.

All of the data from the image scanner 6 is temporarily stored in the image data storage memory 7.

Thereafter, the density of the image data storage memory 7 is subjected to density conversion (reduction lj\) by the density conversion circuit 8 so that it matches the number of pixels of the display device]O, and the data is written into the display memory 9.

As a result, the display device 10 performs display.

Further, the data in the image data storage memory 7 is compressed and encoded by the encoding circuit 11, and the data in the image data storage memory 7 is compressed and encoded.
The encoded data is stored in the .

According to this configuration, the data in the memory 7 that stores all the data from the image scanner 6 is density-converted and displayed, so even if the number of input pixels is greater than the number of pixels of the display device 10, This is advantageous in that the entire image can be displayed.

However, conversely, in this configuration, at least the scanner 6
There is a problem in that the input image cannot be confirmed until all input from .

(Problem to be Solved by the Invention) As described above, with conventional image data input processing devices, no matter which method is used, it is not possible to perform input processing in which images are sequentially and finally displayed in their entirety while being input. , the operability was poor.

The present invention has been made in view of the problems of the prior art, and its purpose is to enable input processing in which all the images are sequentially and finally displayed while the above-mentioned input is being made. An object of the present invention is to provide an image data input processing device.

[Structure of the invention]

(Means for Solving the Problems) The image data manual processing device of the present invention includes an image scanner that reads an image and outputs digitized raster scan data, a bitmap memory, and a display device that displays data in the bitmap memory. It is equipped with a display device and a density conversion means for converting the density of the data from the image scanner according to the number of pixels of the display device and storing it in the bitmap memory, and the data from the image scanner is sequentially converted by the density conversion means. It is characterized in that the density is converted and written to the bitmap memory.

(Function) According to the present invention, since the data from the image scanner is successively density-converted and displayed, especially when using a handy scanner, no matter how high-definition the data is, , the scan range and read density can be checked immediately, greatly improving operability.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of an image data input processing device according to an embodiment of the present invention.

In this figure, 13 is an image scanner. This image scanner 13 outputs digitized raster scan data of the read image.

14 is a density conversion circuit, 15 is a display memory consisting of a bitmap memory, and 16 is a display device.

The density conversion circuit 14 sequentially converts the density of data from the image scanner 13 according to the number of pixels in the image display area of the display device 16 and stores the data in the display memory 15. As a result, images input from the image scanner 13 are sequentially displayed on the art dealer on the display device 16.

17 is an encoding circuit, and 18 is a memory for storing image data. The encoding circuit 17 firstly encodes the image scanner 1.
The data input speed from step 3 is compared with its own processing capacity to determine whether real-time encoding is possible. For example, if it takes 1 ns per bit, the scanner 1 will be able to input the next bit within that ins.
When data from No. 3 arrives, it is determined that it cannot be encoded. Further, when data arrives from the scanner 13 with a time width of Ins or more, it is determined that encoding is possible.

When this encoding circuit 17 determines that encoding is not possible, the raw data is transferred directly to the image data storage memory 18.
Store in.

On the other hand, if it is determined that encoding is possible, the encoding circuit 17 encodes the data from the scanner 13 in real time and stores it in the image data storage memory 18.

According to the system constructed as described above, the data from the image scanner 13 is stored in its original resolution, while the data from the image scanner 13 is sequentially density-converted and displayed, and human images can be displayed in real time. It can be confirmed.

〔Effect of the invention〕

As explained above, according to the present invention, the data from the image scanner is successively density-converted and displayed, so it does not matter how high-definition the data is, especially when using a handy scanner. However, the scan range and read density can be checked immediately, greatly improving operability.
