You may do it. In this case, the image display means 1 has three primary colors.
It is necessary to have a mechanism to transmit light. In the above example, a color image is read.
Has been described, but the image reading method of the present invention has been described.
The method can also be applied to read black and white images of objects,
This can contribute to improving the image quality of the read image. As described above, the image reading method of the present invention
And the device consists of reflected light from the object and disturbance light
The received light signal consisting only of disturbance light is subtracted from the received light signal to
Since the image signal of the elephant is obtained, disturbances such as illumination light
Removing the effects of light to obtain accurate image data of the object
Can be. The image reading method and apparatus of the present invention
In the above, the wavelength band of red light, green light and blue light is selectively passed.
A filter is provided for the shutter operation of the optical sensor.
Since the influence of disturbance light has been removed, illumination light etc.
Removes the effects of ambient light to create a clear color image of the object.
Obtainable. Further, the input / output integrated information operation device of the present invention
In such a device, such an image reading device is used as an image input means.
Apply to obtain a clear color image of the input presentation.
And make it easy to colorize the input image.
it can.
