Embodiment Construction

[0061] Hereinafter, an embodiment of an image printing apparatus equipped with the film image reading apparatus of the present invention will be described based on the drawings.

[0062] The image printing device IP in the embodiment of the present invention adopts a digital exposure type, such as figure 1 As shown, it has a film scanner 3 used as a film image reading device for reading the image of a developed photo film (hereinafter referred to as film) 1 as digital image data by a film developing machine not shown in the figure, and a controller 7 for processing the obtained digital image data to generate print data, a digital printing unit 5 for exposing an image on the printing paper 2 based on the print data, and a controller for developing the exposed printing paper 2 Development processing part 6. The printing paper 2 developed in the developing processing section 6 undergoes a drying process to complete a printed image, and then is discharged.

[0063] The film scan...

Abstract

The present invention discloses a film image readout device, which is provided with a lighting optical system (31) that comprises a light source, a camera optical system (32), a image readout sensor (IS) that comprises a sensor element (33a) for visible light and a sensor element (34a) for infrared light, and a controller (7). The present invention is characterized in that the device also comprises a zoom lens unit (32a) that can change the lens rate of imaging on the film that is on the front surface of the sensor element for infrared light under the operation of the controller (7), and an illuminator (FT) that consists of a glass plate or a lens and is used for changing the focusing position. The illuminator (FT) is arranged between the zoom lens unit (32a) and the sensor element (34a) for infrared light, and can realize a retracing operation between the zoom lens unit (32a) and the sensor element (34a) for infrared light, according to the rate change of the zoom lens unit (32a) under the drive of a drive device, and can redress the change of the focusing position, which is caused by the rate change.

Description

technical field [0001] The invention relates to a film image readout device and its adjustment method, capable of irradiating visible light and infrared light emitted by a light source on a film, and reading film images by using a visible light sensor element and an infrared light sensor element. Background technique [0002] A film image readout device is a device that irradiates light emitted from a light source onto a film, generally detects the transmitted light with a CCD sensor, and then reads out a photographed image on the film. [0003] The basic function of such a film image reading device is to read photographic images on the film. However, in recent years, scratches and dust on the film have also been detected as images. position, to consider correcting the read-out image affected by these scratches and dust to improve the quality of the image. [0004] The detection of the above-mentioned flaws and dust is carried out based on the obtained infrared image of the...
