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: 23
Claim 1
Independent Claim
118 words
An image reading apparatus comprising: an image pick-up device which picks up images recorded on a recording medium; a mover which moves the image pick-up device and the recording medium relative to each other at one of a first speed and a second speed, the second speed being faster than the first speed; and an exposure controller which controls an exposure of the image pick-up device, the exposure controller including: a light adjuster which is operable to adjust the amount of light reaching the image pick-up device from an image, and to fixedly hold a predetermined light amount when the mover moves the image pick-up device and the recording medium relative to each other at the second speed.
Claim 2
Dependent Claim
118 words
An image reading apparatus comprising: an image pick-up device which picks up images recorded on a recording medium; a mover which moves the image pick-up device and the recording medium relative to each other at one of a first speed and a second speed, the second speed being faster than the first speed; and an exposure controller which controls an exposure of the image pick-up device, the exposure controller including: a light adjuster which is operable to adjust the amount of light reaching the image pick-up device from an image, and to fixedly hold a predetermined light amount when the mover moves the image pick-up device and the recording medium relative to each other at the second speed.
Claim 3
Dependent Claim
45 words
An image reading apparatus according to claim 1, wherein the mover moves the image pick-up device and the recording medium relative to each other at the first speed when images are picked up individually and at the second speed when images are picked up continuously.
Claim 4
Dependent Claim
16 words
