Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention comprises an image reading device such as a scanner for reading an image on a sheet surface of a document or the like, and a control device such as a personal computer for processing a read image output from the image reading device. And an image reading system.

[0002]

2. Description of the Related Art In recent years, with the development of color printing machines, the number of color originals has increased, and accordingly, an image reading apparatus has been proposed to output a color image as a color image rather than a gray image reading apparatus which outputs an original as a gray image. An image reading device is required.

A method of electrically reading a document as gray image data by a gray image reading apparatus is, for example, using an LED of one color and an image sensor, causing the LED to emit light, and receiving the reflected light by the image sensor. A method of converting the amount of received light into a voltage is well known.

A method of reading a document as color image data by a color image reading device is to sequentially turn on red, green and blue LEDs using three red, green and blue LEDs and an image sensor, and to reflect each reflected light. A method of receiving light and capturing a red component, a blue component, and a green component is well known. A color image whose data amount is nearly three times as large as that of a gray image can be easily stored nowadays when the storage means has a large capacity.

By the way, a color document is not always color on both sides. The back surface is relatively gray compared to the front surface, which emphasizes flashiness and legibility. Therefore, it is often sufficient to read the front surface with a color image and the back surface with a gray image.

Therefore, recently, an image reading apparatus including a color reading unit for reading a color image on the front side of a document and a gray scale reading unit for reading a gray image on the back side has been put into practical use.

[0007] These image reading devices are usually connected to a control device such as a personal computer. The control device includes a driver that implements processing unique to the image reading device, and a user who receives image data from the driver and receives the image data from the driver. An application that allows free access to data is installed. The user reads an image from the image reading device using this application.

In general, image data from an image reading device is sent to a driver in an external control device, and a predetermined process such as compression is performed in the driver. Then, the processed data is passed to the application.

[0009]

However, in the above-described image reading apparatus having a color reading unit on the front side and a gray scale reading unit on the back side, the front side image is a color image and the back side image is a gray image in the driver. There is a problem that many standard applications cannot handle this two-sided image because the image is output to the application. In other words, in a standard application, in the case of double-sided reading, it is assumed that a color image is output from the driver for both the front image and the back image, or a gray image is output from the driver for both the front image and the back image. Therefore, one side cannot handle a two-sided image of a color image and the other a gray image.

In view of the above-mentioned conventional problems, the present invention can obtain a read image which can be processed by all applications even when reading both sides of a document with a color image on one side and a gray image on the other side. It is an object to provide an image reading system and the like.
