DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image processing apparatus for erasing a black frame or masking an unnecessary area from an image recorded on a microfilm and outputting the processed image to a printer or other external equipment. .

[0002]

2. Description of the Related Art An image on a microfilm is read using a CCD line sensor or an image sensor, and the image is displayed on a CRT to perform predetermined image processing or to erase a part of the area. An image processing apparatus that performs editing by combining a plurality of images is known. For example, when an image is read from a negative microfilm by a CCD line sensor or the like and the image signal is positively displayed on a CRT or the like, a black frame occurs around the original. Therefore, it is necessary to delete the black frame. When editing an image or sending an image to another device or printing it out, it is necessary to erase unnecessary or confidential areas by masking.

Conventionally, both the black frame and the masking area have been whitened, erased and displayed on a CRT, and the displayed image is directly output to a printer or an external device. On the other hand, in particular, it is often desired to confirm the contents of the masking area during the image editing process. However, once the masking area was changed to white, its contents could not be confirmed, and the editing operation had to be started again from reading the first image. This made editing work cumbersome.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances, and it is intended to output an image recorded on a microfilm to a printer or an external device after image processing.
Enter the masking area or black frame area to be erased and
It is easy to set, and even after inputting the masking process, the contents of this area can be confirmed on a display screen such as a CRT, and the black frame that does not need to be confirmed later can be completely changed to white. It is an object of the present invention to provide an image processing apparatus capable of performing the above.

Reference numeral 48 denotes a compression / decompression processing unit,
4 and 36 are connected. The compression / decompression processing unit 48
Performs compression processing when transferring the read image data to an external device such as a facsimile or another microfilm reader, and decompresses and restores the data transferred by the compressed data from the external device. And the like.

Reference numeral 50 denotes an image processing unit as image processing means, which is connected to both buses 34 and 36. The processing unit 50 performs various spatial filtering processes such as edge enhancement, thinning process, dither process, etc., based on the read raw data, and processes such as image enlargement / reduction.

Reference numeral 52 denotes a masking processing unit serving as masking means. The masking area input from the touch panel 70 serving as the area input means described later is described below by making its contents identifiable, ie, readable , and distinguishable from other areas. Is displayed on the CRT 66. In other words, the black and white of the masking area is inverted for display. Reference numeral 54 denotes a black frame erasing processing unit serving as a black frame erasing means, which performs a process of changing the black frame area input from the touch panel 70 to white.

Reference numeral 56 denotes an image data transfer (I-DMA;
Image Direct Memory Acces
s) A control unit, which controls data transfer directly between various input / output interfaces and memories, or between memories. That is, in this embodiment, a DMA method is employed in which image data is transferred without passing through the CPU 38. The CPU 38 sets predetermined parameters such as a transfer start memory address and the number of transfers to the I-DMA control unit 56, Does not need to perform any processing until the transfer is completed.

Reference numeral 58 denotes a disk input / output interface, which is connected to an external memory device 60 such as an optical disk and the bus 36.

My device read from the external memory device 60 such as an optical disk
It may be a black film positive image . CPU3
8 may be a microfilm positive image sent from another image processing apparatus connected to a telephone line or a dedicated line.

FIG . 2 shows a screen during the masking process. If a masking area is input from the touch panel 70, this area is masked. Therefore, this masking area is erased when printing with the printer 64, when recording in the external memory device 60, or when transferring to another external device . On the screen 66B, this masking area is displayed in black and white inverted. That is, FIG.
By rubbing the masking area 84 with a fingertip, the area 84 is sequentially input as this area 84 is sequentially input.
While being added, the image is inverted as black and white as shown in FIG. 3 and displayed as 84A. Also, if the area 86 of the drawing or photograph in FIG. 2 is rubbed, the area is reversed black and white as indicated by 86A in FIG.

[0022] In carrying out the black border erase, processing switching key 80
If the screen 66A is switched to the black frame erasure processing screen by b, and the area of the black frame 82 is rubbed with a fingertip, the black frame 82 is sequentially erased from the rubbed place. FIG. 3 shows a state in which the black frame 82 has been erased.
