摘要:
An image processing method in which an image of an original is read by an image input device, the read image data is converted to density data used when printing onto a photosensitive material, and an image is obtained on the photosensitive material by digital exposure, wherein, when the image data is converted to the density data used when printing onto the photosensitive material, the image data is corrected on the basis of parameters determined by combinations of print finish characteristics, including at least image input device characteristics, kind of original, kind of photosensitive material, and exposure amount characteristics, which affect a print image when the image of the original is printed onto the photosensitive material by an analogue exposure system. On the basis of the above parameters, the density data is obtained while the image data is corrected. For this reason, an image finish print in the digital exposure system can obtain an image quality which is equal to that of a finish print in an analogue exposure system.

An image recording apparatus with good color reproduction and easy color adjusting function. An image recording apparatus includes a first color correction unit coupled to receive image signals from the image signal source, a second color correction unit coupled to receive output image signals of the first color correction unit, and a third color correction unit coupled to receive output image signals of the second color correction unit. The image recording apparatus further includes an adjusting device for at least the first color correction unit and the third color correction unit, and an adjustment information entering device. Good color reproduction is realized with color correction and data compression, and is not accompanied by hue change in color perception. Manufacturing variations in the color output unit are corrected by the third color correction unit. Easy setting of the reference for color adjustment independently of the input image signals is also realized by the unit.

A vibration or shaking feeder combined with a drum which is rotated at high speed is disclosed. The vibration feeder includes a container having a helical ledge around the inner wall of the container for making articles in the container travel to rise up the helical ledge by vibratory motion of the container. The articles advanced up to the uppermost ledge are transferred to the outer drum rotated at high speed and fed to a next stage for further processing.
