Abstract

PURPOSE:To record a picture without distortion or the like even when an uneven rotation takes place in a motor of a scanning system or the like by using a same scanning means so as to expose a picture nearly at the same time of image pickup. CONSTITUTION:When a picture and a photosensing material are set, a main scanning means 36 and a subscanning means 66 are activated and a picture element on the scanning point of an original picture by the scanning of the original picture is subject to 3 color decomposition photometry and the data is converted into a 3 color picture data. The quality of light of a light emission section 58 is regulated based on the picture data and the picture of the original picture is recorded on the photo sensing material nearly at the same time of reading. Thus, even when uneven rotation takes place in the scanning system, the picture is recorded without distortion without the effect of uneven rotation.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention provides a method for reading an image of an original painting.1. :Related to film scanners and recorders that record images on photosensitive materials.

[Conventional technology]

A film scanner/recorder has a built-in scanner system for reading the original image and a recorder system for recording the read image on a photosensitive material.

[Problems to be Solved by the Invention] In the above-mentioned film scanner/recorder, separate scanning means are provided for the scanner system and the recorder system, and image reading and recording are performed by the separate scanning means. There is a problem in that when rotational unevenness or the like occurs, the image is recorded in a distorted manner.

The present invention is intended to solve the above-mentioned problems, and an object of the present invention is to provide a film scanner/recorder that can record images without distortion even when rotational unevenness or the like occurs in the scanning system.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a rotating body, a means for setting an original image and a photosensitive material facing the circumferential surface of the rotating body, and one axis of the rotating body. A light-receiving part is placed facing the end and measures each pixel of the original image by separating it into three colors. A light-emitting part is placed facing the other shaft end of the rotating body and has adjustable light quality. an imaging optical system that forms an image of the original image on a light-receiving section, an exposure optical system that is arranged on a rotating body and that images light from a light-emitting section on a photosensitive material, and a main scanning means that rotates the rotating body. , a sub-scanning means for sub-scanning the rotating body by moving it in the axial direction of the rotating body, and a means for controlling the light quality of the light-emitting section based on the image signal output from the light-receiving section.

[Effect]

When the original image and photosensitive material are set, the main scanning means and the sub-scanning means are activated. By scanning the image of the original image, the pixels on the scanning points of the original image are subjected to three-color separation photometry and converted into three-color image data. Since the light quality of the light emitting section is adjusted based on this image data, the original image is recorded on the photosensitive material almost at the same time as it is read.

The image processing unit 74 corrects differences in spectral characteristics between the imaging optical system 40 and the light receiving sensor 54 and the color negative film 30 to be recorded. The image signal after color correction is sent to the driver 76, and based on this image signal, the amount of light emitted from the LEDs 59 and 60 and the fluorescent display tube 61 is controlled to correspond to the three-color density of the original image at the scanning point of the imaging optical system 40. to adjust the light quality. The quality-adjusted printing light reaches the optical fiber 48 after passing through a mask 63 and a lens 64. This optical fiber 4
The printing light that has passed through the lens 50 is focused on the negative film 30 of the film cartridge 32 as a spot light.

Next, the operation of this embodiment will be explained. First, the film cartridge 32 is set on the exposure body 24.

Next, the color negative film 10 to be imaged is set on the imaging film stand 12.

After this, when you operate the record key, the controller master
drives each scanning means 36.66. As a result, the image on the negative film 10 is scanned, and the image signal is sent from the light receiving sensor 54 to the image processing section 74 . Image processing section 7
After color correction in step 4, the image signal is sent to driver 76. The driver 76 controls the red LED 59 . of the light emitting section 58 . The light quality emitted from the small hole 62 of the mask 63 is adjusted by controlling the amount of light emitted from the green LED 60 and the fluorescent display tube 61. The quality-adjusted printing light passes through the exposure optical system 42 and exposes the negative film 30 on the exposure film stand 18 in a dotted manner. Since this exposure optical system 42 is also scanned in the same way as the imaging optical system 40, the original image is exposed onto the negative film 30.

When the exposure of one frame is completed, the negative film 32 is advanced by one frame, and the next order of negative film IO is sent to the imaging film table 12, and a new image is exposed on the color negative film 3Q in the same manner. Ru. When a predetermined number of images are exposed on the color negative film 30, the exposed film cartridge 32 is taken out from the exposure body 24 and subjected to development processing.

In the above embodiment, the negative film 10 is set on the exposure film table 12 and the image on the negative film 10 is copied, but color paper may be set instead.

Further, in the above embodiment, an image of the negative film 10 is simply taken and this image is recorded on the unexposed negative film 30, but the present invention is not limited to this, and the present invention is not limited to this. It is also possible to input an illustration image consisting of individual sentences in advance to the image processing section, electrically synthesize the illustration image and the main image, and expose this synthesized image onto a negative film. This makes it possible to create postcards and the like in large quantities by printing and exposing color paper using a general photoprinting device using a negative film on which a composite image has been recorded.

〔Effect of the invention〕

As explained above, according to the present invention, since the exposure is performed almost simultaneously with imaging using the same scanning means,
Even if rotational unevenness occurs in the motor of the scanning system, the image is not affected by the rotational unevenness, so images without distortion can be recorded. In addition, since the light receiving part and the light emitting part are arranged facing both ends of the rotating shaft of the rotating body,
The rotating body can be optically connected to the light-receiving section and the light-emitting section, and there is no electrical connection between the movable section and the main body, simplifying the configuration and improving reliability and durability. can be improved.
