Abstract

PURPOSE:To eliminate the need for an expensive optical system and to reduce the cost by displaying an image for initial setting onto a display means via an image pickup means or the like so as to use only one optical path in comparison with a conventional viewer system using a screen. CONSTITUTION:R, G, B digital image signals read from CCD line sensors 3061-3063 after being subject to processing of picture element deviation correction or the like at an image deviation correction circuit 3029 or the like enter a display circuit 106, and a line buffer memory 101 absorbs the difference of the resolution between the sensors 3061-3063 and a CRT unit 105. That is, a memory 101 interleaves the data. The signal interleaved by the memory 101 is controlled by an address counter 103 and written in an SRAM 102. When a picture is displayed on a display screen of the unit 105, the digital image signal read from the SRAM 102 is converted into an analog signal by a D/A converter 104, fed to the unit 105, where the signal is displayed on the screen.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image reading device that reads images from a transparent original such as a photographic film.

[Prior Art] Conventionally, in this type of image reading device, after setting an original film such as 35 mm photographic film at the image reading position of the device, the light from an illumination lamp is directed onto the original film before the actual image reading starts. The transmitted light image of the original was displayed on a special pure screen using an imaging lens. The user is configured to use the image displayed on the Pure to perform operations such as trimming or moving the image.

[Problems to be Solved by the Invention] However, in the conventional example as described above, when reading an image, the first optical path for forming an image on a line sensor (imaging device) is used as the optical path of the light transmitted through the original film. The optical path passes through the imaging lens to reach the line sensor, and the operating pure light passes through a second imaging lens different from the first imaging lens mentioned above during initial settings such as frame designation such as trimming. Requires two optical paths, one projected onto the
Furthermore, since the illumination lamp serving as the light source remains lit while projecting onto the operating pure, there are the following drawbacks.

(1) Since two optical paths are required, the optical path space becomes nearly twice as large as the minimum necessary for image reading, which is the original basic function, and the device becomes larger.

(2) Furthermore, an accompanying mirror for switching the optical path
Since a solenoid to move the cellar and an imaging lens for the pure were required, a considerably large space was required and manufacturing costs increased.

(3) When the above-mentioned operation pure was used (that is, during initial settings), the illumination lamp continued to flash, and the irradiation light caused discoloration and deformation of the photographic film that served as the original.

(4) Furthermore, when the original film is a negative film, the image is displayed in a pure state for operation in its negative image state, making it difficult to see the displayed image and making operations such as color balance difficult.

(5) Since the conveyance of the original film to the image reading position and the pure display means were all performed manually each time, the operations were complicated and the operability was poor.

It is an object of the present invention to eliminate the above-mentioned drawbacks, to have a simple structure, small size, and low cost, to prevent discoloration and deformation of the original film, and to improve operability by making it easier to see images during initial settings. An object of the present invention is to provide an image reading device that can be used.

[Uses] Since the present invention has the above-described configuration, the following effects can be obtained.

(1) Since the image for initial settings is displayed on the display means via an imaging means, etc., there is only one optical path, compared to the conventional pure one-way system using a screen. Expensive optical systems such as movable mirrors and imaging lenses are not required, and the structure is simplified, resulting in compactness and cost reduction.

(2) In addition, since the storage means stores data in a timely manner according to the display screen and then displays it on the display means,
The difference in resolution between the imaging means and the display means can be easily adjusted, and since the lamp light irradiation time on the original film only needs to be the time required to write to the storage means, the irradiation time is significantly shortened, and the lamp light irradiation time is reduced accordingly. The lifespan of will be longer,
Running costs are reduced, and discoloration and deformation of the original film are prevented.

(3) The imaging means detects whether the transparent original is a negative image or a positive image, and if it is detected as a negative image, it is inverted by the signal inversion means and then displayed on the display means. is always displayed as a positive image, making it easier to see the displayed image and making initial settings such as color balance easier.

(4) Each time it is detected that the image of the transparent original has reached the reading position based on the detection signal of the imaging means, the display means automatically displays an image for initial setting, thereby making it easier to operate. You can further improve your sexual performance.
