ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to an image reading apparatus to read an image, and an image forming apparatus to digitally print-process the image information of the image.
In the conventional analog type image forming apparatus, factors to determine the print image quality are determined by the performance of an enlarging lens, and the apparatus has no function to adjust the print image quality. Further, the processing capacity to print each frame of the film largely depends on the F-number of the lens to be used.
In contrast to this, in the digital type image forming apparatus, factors to determine the image quality are determined by the interrelationship or the like between the resolving power of the print output and the number of pixels of the original image to be inputted.
Conventionally, the image information necessary for the maximum print size is always read out from an image input apparatus such as a film scanner, or similar apparatus, and used for print processing. However, in this structure, an image information amount becomes large, and a long period of time is necessary for image processing or data transferring for image input or output, therefore, the print processing capacity can not be increased.
Further, there has been a problem that the image quality of a printed image is affected by a state of the image forming apparatus.
SUMMARY OF THE INVENTION
An object of the present invention is to provide an image reading apparatus or an image forming apparatus in which the image quality of the output image is not deteriorated, and which can provide the optimum print processing capacity even when printing is carried out in any size.
Furthermore, an another object of the present invention is to provide an image forming apparatus wherein a photographing condition in which a little deterioration in an image quality is observed, can be obtained irrespective of a state of the image forming apparatus.
As a result of deep consideration to solve such the problem, the present inventor found that it is important to calculate the number of pixels to optimize the print image quality, image processing time, and image data transferring time from the print size and negative film information, and to set the resolving power of the film image pick-up section and to calculate the magnifying power, corresponding to the number of pixels; and therefore, it is necessary to determine the resolving power of the film image pick-up based on the film size information and print size information, which are read prior to the film image pick-up, and thereby, the present invention is completed.
The above object is achieved by any one of the following structures (1), (2) and (3).
(1) An image reading apparatus comprising: a size detecting means for detecting a first size of a first image recorded on an original; an input means for inputting a second size of a second image to be recorded on a recording medium by an image recording apparatus; a determining means for determining a reading condition to read the first image according to the first size and the second size; and a reading means for reading the first image according to the reading condition to obtain information of the first image.
(2) An image recording apparatus comprising: a size detecting means for detecting a first size of a first image recorded on an original; a reading means for reading the first image recorded on the original according to a reading condition to obtain information of the first image; an image recording means for recording the second image on the recording medium according to the information of the first image; an inputting means for inputting a second size of the second image; and a determining means for determining the reading condition according to the first size and the second size.
(3) An image recording apparatus comprising: a reading means for reading a first image recorded on an original according to a reading condition to obtain information of the first image; an image recording means for recording a second image on a recording medium according to the information of the first image; a status inputting means for inputting a status of the image recording means; and a determining means for determining the reading condition according to the status.
As a preferable embodiment of the present invention, a means for adjusting an image pick-up condition of the image pick-up device has a structure to select and output the output data from the image pick-up device as needed.
Further, as another preferable embodiment, a zoom lens or a similar means having a variable magnification function is provided in the image pick-up system as the means for adjusting an image pick-up condition of the image pick-up device.
