Abstract

PURPOSE:To obtain a hard copy of plural pictures by providing a picture memory section that stores plural picture information and generating time series composite picture signals and raster storing. CONSTITUTION:When video picture signals V from a medical apparatus are inputted to an A/D converter 2, the picture signals V are digitalized by clock pulse from a clock pulse generator 3 and stored in a picture memory 4. Picture frames F1-F6 can be raster recorded by providing an output decoder of the picture memory 4 in an X address counter 5 and a Y address counter 6 when writing picture information in the memory 4 and making this a preset counter. When addresses of the picture memory 4 are designated successively when reading the picture information, time series composite picture signals are obtained, and reproduced pictures P1-P6 are obtained on a frame 14.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an image recording device that records a plurality of images on one hard copy.

A conventional multi-format camera that records multiple images on one hard copy is a CRT photographing device.
An input image is displayed on a CRT and projected onto a silver halide film using a lens optical system. When shooting multiple images on the same film with this multi-format camera, if only the lens optical system is moved, the optical axis will be oblique to the CRT surface and film surface, causing image distortion. Become. Therefore, high-precision multi-format cameras move the lens optics and the CRT or film together so that the optical axis is always perpendicular to the CRT and film surfaces; this method is called on-axis. ing. However, this on-axis method has the disadvantage that it takes time to align the optical axes, and it takes a long time to take multiple images.

Furthermore, in order to solve this problem, if a plurality of images are displayed on the CRT at once, the number of pixels will be insufficient and a clear photographed image will not be obtained.

An object of the present invention is to provide an image recording device that eliminates the above-mentioned drawbacks and is capable of recording a plurality of images on a recording material in an extremely short period of time. In a recording device that scans and obtains a hard copy,
An image storage unit that stores a plurality of pieces of image information is provided, and a time-series composite image signal is generated by extracting a predetermined part of each of the plurality of image information stored in the image storage unit, and a time-series composite image signal is generated, and a part of the plurality of images is extracted. The present invention is characterized in that it has a configuration in which a plurality of images are recorded in a raster manner while each image is recorded in one continuous scan.

Figure 1 shows six image frames F1 to F on the same recording material.
In the conventional multi-format camera, these six image frames FI-Fll were recorded separately one frame at a time, but in the present invention, these six image frames FI-Fll are recorded separately. All the image information of F8 is partially stored in the memory, and each image frame F8 is stored as shown in FIG.

FIG. 4 is a block diagram of an embodiment when applied to laser beam recording. For example, a video image signal V to be converted into an image output from a medical device such as an NMR (nuclear magnetic resonance apparatus), an XCT (X-ray tomography apparatus), or an ultrasound tomography apparatus (not shown) is passed through an amplifier l to /D converter 2. This A/D converter 2 receives the image signal V by the clock pulse from the clock pulse generator 3.

3N). For this purpose, an X address counter 5 and a Y address counter 6 are connected to the image memory 4, and the address is controlled by a frame counter 7.

That is, at the time when image information is written to the image memory 4, the X address counter 5 is an M-ary counter, and the image frame F1. 1 to M are output at F3 and F5, and frames F2, F4 . FB outputs N+1 to 2N. Further, the Y address counter 6 is an N-ary counter, and frames F1 and F2 output 1 to N, frames F3 and F4 output N+1 to 2N, and frames F5 and F8 output 2N+1.
~3N is output. These are X address counter 5, Y
This can be realized by providing the address counter 6 with a decoder for the output of the image memory 4 and using this as a preset counter. In this way, the image frames F1 to F6 shown in FIG. 1 can be stored in the image memory 4 as shown in FIG.

At the time of reading image information from the image memory 4,
X address counter 5 is 1 to 2M as a 2M base counter.

The laser beam generated from the laser oscillator 11 and passed through the mirror 12 is luminance-modulated by the acousto-optic element IO. This modulated laser beam is one-dimensionally scanned by the rotating polygon mirror 13 and linearly scans the film 14.
