Ink jet image recording method and apparatus using the method

In order to provide an image reading apparatus, which can read images on a monochromatically developed color photographic film, it is provided a reading conditions changing portion, which changes reading conditions of sensors on the basis of information applied to the color photosensitive material, or is provided light sources which irradiate light, having at least one of wavelength and light quantity being different from that of the other, at an emulsion surface side and a support surface side of the color photosensitive material, respectively.

Image reading apparatus, image recording medium and image forming apparatus

Microarea light-emitting diodes, which have no variation in light output power the like due to mode-hopping, are used and changes in properties such as light output and the like due to generated heat are prevented. Pulses having a constant period and a substantially constant power are used, a number of the pulses within a period for forming an image corresponding to one pixel is determined on the basis of image data, and light beams emitted from the microarea light-emitting diodes are modulated by pulse signals including the determined pulses.

Light beam scanning device for micro-area light source

An image reading device in which an image can be read efficiently and at high speed and with high image quality with little heat being generated at a time of light emission, and the device can be made compact. After lights of respective colors are collected and focused, the light is diffused in a vicinity of a film. Therefore, almost all of lights emitted from LED chip groups can be guided to a surface of the film.

Image reading device

Since amounts of illuminated light of each color are well-balanced by using a light source generating a small amount of heat and emitting light of a high color temperature during light emission, images can be read at high speed and with high accuracy. LED chips are applied for a light source, and are arranged by color so as to form substantially straight lines on an aluminum substrate, at a high density. Emitted light is made to be incident on a photographic film via an acrylic block. Since light emitted from the LED chips has a high color temperature and includes a large amount of light of short wavelengths, an SN ratio of a read image is excellent and the image can be read at high speed. A heat pipe is piped at the rear surface side of the aluminum substrate and a coolant is circulated inside the pipe. Since heat generated by the LED chips is transmitted to the heat pipe through a heat exchange action between the light source and the coolant, the amount of light emitted from the LED chips does not fluctuate.

Image reading apparatus

An image recording method in which an image is exposed onto a negative or positive recording material, and a pattern having a predetermined color and a predetermined density is exposed onto a region of the recording material outside of a region on which the image is exposed. The recording material on which the image and pattern are exposed is developed. Digital image data and digital pattern data are obtained by digitally reading, from the developed recording material, the image and the pattern which have faded and deteriorated over time. Fading correction of the digital image data is carried out on the basis of the color and the density of the pattern based on the obtained digital pattern data, and on the basis of the predetermined color and the predetermined density of the pattern. The image is newly recorded onto another recording material on the basis of the digital image data which has been subjected to fading correction. Accordingly, fading correction processing is suitably performed.

Recording material and image recording method

A photosensitive material which when imagewise exposed to record a latent image thereon is formed with an image by heating with a prescribed processing material superimposed thereon is used as a photographic film or the like, the photosensitive material is exposed to record an image thereon, the exposed photosensitive material is developed by superimposing and heating the photosensitive material and the processing material to form the image on the photosensitive material and then peeling the photosensitive material formed with the image off the processing material, the developed image on the photosensitive material is read with a scanner to obtain image data representing the image, and the image data are subjected to prescribed image processing to generate reproducible digital image data.

Image forming method and system

A system for monitoring the amount of light emitted from a surface emitting laser includes a beam splitter which is fixed to the surface emitting laser and splits a part of a laser beam emitted from the laser as a monitor light, and a photodetector which detects the monitor light.

System for monitoring amount of light emitted from surface emitting laser

The density of cyan color of an image at the peak wavelength .lambda..sub.C1 in the spectral absorption distribution of a developed cyan color dye is detected in the density range of 0-2 as a detection range, and the density of the developed cyan color dye at the wavelength .lambda..sub.C2 deviated from the peak wavelength is detected in the density range of 1-1.75 as a detection range. The density equivalent to the density value detected at the peak wavelength .lambda..sub.C1 in the density range of 2-3.5 is obtained by doubling the density value detected in the density range of 1-1.75 as the detection range. By using the density value thus obtained and the density value detected in the range of 0-2, the cyan color density of the image is obtained in the density range of 0-3.5 as a detection range. Similarly, the density of each color of magenta and yellow is determined. By doing this, the color image can be read accurately by using an apparatus with simple structure.

Method for reading images and apparatus therefor

Scanning exposure for three pigments by three optical beams is carried out during a single main scanning. An angle of incidence and an angle between respective light beams are determined so as to prevent overlapping of scanning exposure. As a result, a single modulator can be used in modulating light beams. With respect to maximum swing angle of light beam by a flat mirror of a deflecting device, a image can be recorded (scanning exposure) on a sensitive material by a swing angle of about 1/5 by allocating swing width with respect to the center. Thus, a deviation of position of a focusing point and change in speed can be suppressed so that focusing, concentration and the like can be included within an allowable range.

Scanning exposure device

An image exposing device which, on the basis of image data, modulates light beams outputted from three light sources having respectively different wavelengths, and which scans/exposes the light beams onto a photosensitive material. The three light sources includes a first light source having a light-emitting peak wavelength in a vicinity of 635 nm, a second light source having a light-emitting peak wavelength in a range of 670 to 710 nm, and a third light source having a light-emitting peak wavelength in a vicinity of 780 nm. The photosensitive material includes a first photosensitive layer having a peak spectral sensitivity corresponding to the first light source, a second photosensitive layer having a peak spectral sensitivity corresponding to the second light source, and a third photosensitive layer having a peak spectral sensitivity corresponding to the third light source. A sensitivity of the first photosensitive layer with respect to the first light source is at least fifteen times a sensitivity of the second photosensitive layer with respect to the first light source, and a sensitivity of the second photosensitive layer with respect to the second light source is at least fifteen times a sensitivity of the first photosensitive layer with respect to the second light source.

Image exposing device

In a light beam scanning recording device, a color image is recorded on a recording material by scanning the recording material in a main scanning direction and a sub-scanning direction with light beams of three different wavelengths modulated according to an image signal. A light source which emits a plurality of light beams which form a predetermined number of beam spots on the recording material arranged in the sub-scanning direction is used as the light source for emitting light beams of each wavelength, whereby recording is effected simultaneously along the predetermined number of main scanning lines.

Light beam scanning recording device

In the improved image exposing apparatus, light beams of different wavelengths in narrow bands that issue from a plurality of light sources are admitted into a light deflector at different angles and substantially the same main scanning line defined on a light-sensitive material is scanned sequentially at predetermined time intervals by the reflected and deflected light beams. The apparatus is so designed that only one light beam will be admitted into a start synchronizing sensor when start synchronization is to be effected. Thus, even if the beam intensity of any one of the rasters produced in a multi-beam varied angle incidence optical system is not significantly higher than the sensitivity of the start synchronizing sensor which is to perform line synchronization for individual rasters, the intended line start synchronization can positively be effected when a write (exposure) mode is performed on a color light-sensitive material by each raster, whereby the light-sensitive material can be effectively exposed to produce a satisfactory image without defects such as color mismatch.
