Abstract

In order to solve a problem that conventionally there is no image output apparatus in which a wide-band image can be output in a narrow band, an image output apparatus includes: an accepting unit that accepts first-image information, which is information related to a first image of a first band; and multiple image output units that output second images, each of which is an image of a second band that is narrower than or equal to the first band, using the first-image information, wherein a third image obtained as a result of output of the second images by the multiple image output units is an image of a third band that is wider than the first band. Accordingly, it is possible to provide an image output apparatus in which a wide-band image can be output in a narrow band.

         8 . The image output apparatus according to  claim 1 , wherein at least two image output units of the multiple image output units output at least two second images, while shifting, by a predetermined level of precision, positions to which the at least two image output units output the second images. 
     
     
         9 . The image output apparatus according to  claim 1 , wherein at least one image output unit of the multiple image output units includes:
 an image processing part that generates a second image having a number of pixels that is smaller than that of the first image and having a resolution that is higher than that of the first image, using part of the first image; and   an image output part that outputs the second image generated by the image processing part.   
     
     
         10 . The image output apparatus according to  claim 1 , further comprising one or at least two drive units in association with at least one image output unit of the multiple image output units, the drive units being capable of changing a position of the image output unit. 
     
     
         11 . The image output apparatus according to  claim 2 ,
 wherein the control unit determines a position of at least one image output unit of the multiple image output units, and   the image output apparatus further comprises one or at least two drive units in association with the at least one image output unit of the multiple image output units, the drive units changing the position of the image output unit according to the determined position.   
     
     
         12 . An image output method that can be realized by an accepting unit and multiple image output units, comprising:
