Abstract

Abstract An apparatus for reproducing images recorded on successive frames of a film recorded with information, the apparatus includes a film feeder which feeds the film in a first direction and a second direction opposite to the first direction; an information reader which reads the recorded information; a density detector which detects a density of each image; and a controller which controls the film feeder, information reader, and density detector. The information reader is worked when the film is fed in the first direction, the density detector is worked when the film is fed in the second direction. A detected image density is adapted for determining an exposure value at which each image is picked up to reproduce the image.

Claims Analysis

Total Claims: 21
Claim 1
Independent Claim 62 words
An image reproducing apparatus comprising: an image pick-up device which picks up images recorded on a developed film having an unexposed portion; a detector which detects a density of said unexposed portion of the developed film; and an exposure controller which controls an exposure of the image pick-up device based on a detected density of said unexposed portion of the developed film.
Claim 2
Dependent Claim 62 words
An image reproducing apparatus comprising: an image pick-up device which picks up images recorded on a developed film having an unexposed portion; a detector which detects a density of said unexposed portion of the developed film; and an exposure controller which controls an exposure of the image pick-up device based on a detected density of said unexposed portion of the developed film.
Claim 3
Dependent Claim 68 words
An image reproducing apparatus according to claim 1, wherein the exposure controller includes: a diaphragm provided between the image pick-up device and the developed film; and an exposure time changer which is operable to change the exposure time of the image pick-up device; and wherein at least one of the diaphragm and the exposure time changer is operated in accordance with a detected density of said unexposed portion.
Claim 4
Dependent Claim 58 words
An image reproducing apparatus according to claim 1, wherein the image pick-up device has a pre-scanning mode and a main scanning mode, said main scanning mode being executed after the pre-scanning mode; and wherein the exposure controller controls an exposure of the image pick-up device based on a detected density of said unexposed portion in the pre-scanning mode.
Claim 5
Dependent Claim 25 words
An image reproducing apparatus according to claim 1, wherein the image pick-up device includes an image sensor, and wherein the detector includes an image sensor.
Claim 6
Dependent Claim 22 words
An image reproducing apparatus according to claim 1, wherein the image pick-up device and the detector include a single common image sensor.
Claim 7
Dependent Claim 68 words
An image reproducing apparatus comprising: an image pick-up device which picks up images recorded on a developed film having an unexposed portion; a detector which detects a density of said unexposed portion of the developed film; and an image processor which executes an image processing, for an image picked up by the image pick-up device, based on a detected density of said unexposed portion of the developed film.
Claim 8
Dependent Claim 68 words
An image reproducing apparatus comprising: an image pick-up device which picks up images recorded on a developed film having an unexposed portion; a detector which detects a density of said unexposed portion of the developed film; and an image processor which executes an image processing, for an image picked up by the image pick-up device, based on a detected density of said unexposed portion of the developed film.
Claim 9
Dependent Claim 21 words
An image reproducing apparatus according to claim 6, wherein the image processing, executed by the image processor, is white balance control.
Claim 10
Dependent Claim 52 words
An image reproducing apparatus according to claim 6, wherein the image pick-up device has a pre-scanning mode and a main scanning mode, said main scanning mode being executed after the pre-scanning mode, and wherein the image processing, executed by the image processor, is for an image picked up in the pre-scanning mode.
Claim 11
Dependent Claim 25 words
An image reproducing apparatus according to claim 6, wherein the image pick-up device includes an image sensor, and wherein the detector includes an image sensor.
Claim 12
Dependent Claim 22 words
An image reproducing apparatus according to claim 6, wherein the image pick-up device and the detector include a single common image sensor.
Claim 13
Dependent Claim 71 words
An image reproducing apparatus comprising: a first detector which detects a density of an unexposed portion of a developed film; a second detector which detects a density of an exposed portion of the developed film and picks up images recorded on the exposed portion; controller which controls the second detector based on a density detected by the first detector; and a reproducer which reproduces images picked up by the second detector.
Claim 14
Dependent Claim 71 words
An image reproducing apparatus comprising: a first detector which detects a density of an unexposed portion of a developed film; a second detector which detects a density of an exposed portion of the developed film and picks up images recorded on the exposed portion; controller which controls the second detector based on a density detected by the first detector; and a reproducer which reproduces images picked up by the second detector.
Claim 15
Dependent Claim 18 words
An image reproducing apparatus according to claim 11, wherein the controller controls an exposure of the second detector.
Claim 16
Dependent Claim 19 words
An image reproducing apparatus according to claim 12, wherein the controller controls an image processing operation of the reproducer.
Claim 17
Dependent Claim 20 words
An image reproducing apparatus according to claim 11, wherein the reproducer reproduces a plurality of images in a multi-image form.
Claim 18
Dependent Claim 34 words
An image reproducing apparatus according to claim 14, wherein the second detector executes the detection of a density of the exposed portion and the picking up of images recorded on the exposed portion simultaneously.
Claim 19
Dependent Claim 25 words
An image reproducing apparatus according to claim 11, wherein the second detector detects respective densities of a plurality of separate locations in the exposed portion.
Claim 20
Dependent Claim 25 words
An image reproducing apparatus according to claim 11, wherein the first detector includes an image sensor, and wherein the second detector includes an image sensor.
Claim 21
Dependent Claim 20 words
An image reproducing apparatus according to claim 11, wherein the first and second detectors include a single common image sensor.
