     DETAILED DESCRIPTION 
     Exemplary Embodiment 
     Configuration of Communication System 
       FIG. 1  is a schematic diagram illustrating an example of a configuration of a communication system according to an exemplary embodiment of the present invention. 
     In the communication system, an image processing apparatus  1  is connected to external image processing apparatuses  4 A and  4 B for communication through a network  5  that is, for example, a public network. The image processing apparatus  1  and the external image processing apparatuses  4 A and  4 B exchange information with one another by using, for example, a facsimile (hereinafter, referred to as a “FAX”) system. 
     The image processing apparatus  1  is an apparatus having a FAX-transmission/reception function and functions of a printer, a scanner, and a copier, and includes a central processing unit (CPU) having a function of processing information and electronic components such as a flash memory. In the image processing apparatus  1 , an optical scanning unit  14  reads a document  2 , a display  12  displays a result of reading the document  2 , and a FAX communication unit  16  performs FAX transmission. 
     A tablet terminal  3  communicates with the image processing apparatus  1 , for example, wirelessly. The tablet terminal  3  displays the result of reading the document  2  by the optical scanning unit  14  of the image processing apparatus  1 , and controls the image processing apparatus  1  to perform the FAX transmission of the read image of the document  2 . 
     The image processing apparatuses  4 A and  4 B need at least a FAX-transmission/reception function. The image processing apparatuses  4 A and  4 B receive information transmitted from the image processing apparatus  1 , and print or display the information. The image processing apparatuses  4 A and  4 B are each, for example, a printer, but may be a personal computer (PC), a tablet terminal, a mobile phone, or another device that receives and displays information transmitted from the image processing apparatus  1 . 
     The network  5  is, for example, a toll communication network provided by a telecommunication corporation, and is an external network such as a public switched telephone network (PSTN) or an Internet Protocol (IP) communication network. 
       FIG. 2  is a block diagram illustrating an example of a configuration of the image processing apparatus  1 . 
     The image processing apparatus  1  includes a controller  10 , a memory  11 , the display  12 , an operation unit  13 , the optical scanning unit  14 , a printing unit  15 , the FAX communication unit  16 , and a communication unit  17 . The controller  10  includes a CPU, or the like, controls various components, and executes various programs. The memory  11  includes a storage medium such as a flash memory, and is used to store information. The display  12  displays characters, images, and the like. The operation unit  13  is provided for operating the image processing apparatus  1 . The optical scanning unit  14  optically scans a sheet on which characters, images, and the like have been written. The printing unit  15  executes printing on a sheet. The FAX communication unit  16  communicates with external apparatuses through the network  5  by using a FAX system. The communication unit  17  communicates with external apparatuses, for example, wirelessly. 
     The controller  10  executes an image processing program  110  (described later) and thus functions as multiple units such as an optical-scanning controller  100 , a document-image preview displaying unit  101 , a to-be-transmitted-image generating unit  102 , and a FAX communication controller  103 . 
     The optical-scanning controller  100  sets document reading settings such as resolution, size, and color/black-and-white settings for the optical scanning unit  14  on the basis of optical-scanning setting information  111 . The optical-scanning controller  100  controls the optical scanning unit  14  to read the document  2 . 
     The document-image preview displaying unit  101  generates multiple types of preview images from document-image information  112  generated as a result of reading the document  2  with the optical scanning unit  14 , the preview images each having different transmission settings such as resolution, size, and color/black-and-white settings. The document-image preview displaying unit  101  performs display processing on the preview images and displays the preview images on the display  12 . 
     The to-be-transmitted-image generating unit  102  receives, through the operation unit  13 , an operation of selecting one of the multiple types of preview images that are displayed on the display  12  by the document-image preview displaying unit  101 . The to-be-transmitted-image generating unit  102  generates to-be-transmitted-image information  113  as new image information from the document-image information  112 , on the basis of the transmission settings of the selected preview image. 
     The FAX communication controller  103  controls the FAX communication unit  16  to transmit the to-be-transmitted-image information  113  to a destination in destination information  114  or to a destination inputted by a user through the operation unit  13 . 
     The memory  11  is used to store the image processing program  110 , the optical-scanning setting information  111 , the document-image information  112 , the to-be-transmitted-image information  113 , the destination information  114 , and the like. The image processing program  110  causes the controller  10  to operate as the optical-scanning controller  100 , the document-image preview displaying unit  101 , the to-be-transmitted-image generating unit  102 , and the FAX communication controller  103  that are described above. 
     Operation of Image Processing Apparatus 
     Hereinafter, (1) a basic operation, (2) a preview operation, and (3) a FAX Transmission operation of the image processing apparatus  1  according to the exemplary embodiment will be described with reference to  FIGS. 1 to 3 , and  FIG. 6 . 
     (1) Basic Operation 
       FIG. 6  is a flowchart illustrating an example of operation of the image processing apparatus  1 . 
     Firstly, a user of the image processing apparatus  1  operates the operation unit  13  to prepare for FAX transmission. 
     The image processing apparatus  1  starts receiving a FAX transmission request in accordance with a user operation (S 1 ; Yes). The image processing apparatus  1  receives selection or input of the telephone number of a transmission destination, and prompts the user to place the document  2  to be faxed in a document feeder of the optical scanning unit  14 . 
     The user selects or inputs the telephone number of the transmission destination, places the document  2  in the document feeder, and operates the operation unit  13  to cause the optical scanning unit  14  to read the document  2 . 
     The optical-scanning controller  100  of the image processing apparatus  1  sets the document reading settings such as resolution, size, and color/black-and-white settings for the optical scanning unit  14  on the basis of the optical-scanning setting information  111 , and controls the optical scanning unit  14  by using the settings to read the document  2  (S 2 ). In this case, for example, default document reading settings of a resolution of 400 dpi, a size of A4, and a black-and-white setting have been set in the optical-scanning setting information  111 . Note that as the optical-scanning setting information  111 , factory default information set in advance, information set by the user, or information set on the basis of the acquired communication quality of the network  5  may be used. 
     The optical scanning unit  14  reads the document  2 , generates the document-image information  112 , and stores the document-image information  112  in the memory  11  (S 3 ). 
     (2) Preview Operation 
     Next, the document-image preview displaying unit  101  generates multiple types of preview images of the document-image information  112  generated as a result of reading the document  2  with the optical scanning unit  14 , the preview images each having different transmission settings such as resolution, size, and color/black-and-white settings (S 4 ). The document-image preview displaying unit  101  displays the multiple types of preview images on the display  12  (S 5 ). In this case, the document-image preview displaying unit  101  does not change the settings of, for example, a size of A4 and a black-and-white setting. The document-image preview displaying unit  101  generates preview images having resolutions of 200 dpi and 100 dpi, respectively, changed from 400 dpi, and displays the preview images on the display  12 . The settings are changed in order to reduce a data amount of the image information by decreasing the resolution. However, if a data amount is not a consideration, the resolution may be increased by using an image interpolation technique. 
       FIG. 3  is a schematic diagram illustrating an example of a configuration of a preview display screen displayed on the display  12  by the document-image preview displaying unit  101 . 
     A preview display screen  12   a  includes a destination region  120  that displays the telephone number or the like of a transmission destination, a setting region  121  that displays the transmission settings of the preview images, a preview image displaying region  122  in which preview images  101   a  to  101   c  are displayed, a selection frame  123  for selecting one of the preview images  101   a  to  101   c , an enlarge/reduce button  124  for enlarging or reducing the display of the preview images  101   a  to  101   c , and a transmission button  125  for transmitting an image in accordance with the settings of the preview image selected by using the selection frame  123 . 
     The user checks the preview display screen  12   a , and operates the operation unit  13  in the following manner. The user selects one of the preview images  101   a  to  101   c  that has a resolution that the user considers to be appropriate, by using the selection frame  123 , and presses the transmission button  125 . In this case, for example, the preview image  101   b  having a resolution of 200 dpi is selected. 
     (3) FAX Transmission Operation 
     Next, upon receipt of the operation of selecting one of the preview images  101   a  to  101   c  (S 6 ; Yes), the to-be-transmitted-image generating unit  102  generates the to-be-transmitted-image information  113  from the document-image information  112  on the basis of the transmission settings of the selected preview image (S 7 ). In the example described above, the to-be-transmitted-image generating unit  102  generates new to-be-transmitted-image information  113  having a resolution of 200 dpi on the basis of the transmission settings of the document-image information  112 . Note that if the user requests a transmission setting of a resolution exceeding 400 dpi, the processing may return to step S 2  in order to read the document  2  again by using new reading settings. 
     The FAX communication controller  103  controls the FAX communication unit  16  to transmit the to-be-transmitted-image information  113  to a destination in the destination information  114  or a destination inputted by the user through the operation unit  13  (S 8 ).

     Note that the exemplary embodiment of the invention is not limited to the aforementioned exemplary embodiment, and various modifications may be made without departing from the scope of the exemplary embodiment of the invention. For example, the setting to be changed may be size. 
       FIG. 4  is a schematic diagram illustrating another example of the configuration of the preview display screen displayed on the display  12  by the document-image preview displaying unit  101 . 
     A preview display screen  12   b  includes the destination region  120 , the setting region  121 , the preview image displaying region  122 , the selection frame  123 , the enlarge/reduce button  124 , and the transmission button  125 . 
     The user checks the preview display screen  12   b , and operates the operation unit  13  in the following manner. The user selects one of the preview images that has a size that the user considers to be appropriate by using the selection frame  123 , and presses the transmission button  125 . 
     The preview images may also be displayed on the display of the tablet terminal  3 . 
       FIG. 5  is a schematic diagram illustrating an example of a configuration of a preview display screen displayed on the display of the tablet terminal  3  by the document-image preview displaying unit  101 . 
     A preview display screen  30  includes a destination region  300  that displays the telephone number or the like of a transmission destination; a setting region  301  that displays the transmission settings of preview images; a preview image displaying region  302  in which preview images  101   g  to  101   j  are displayed; a selection frame  303  for selecting one of the preview images  101   g  to  101   j ; an enlarged/reduced display region  304  in which one of the preview images  101   g  to  101   j  selected by using the selection frame  303  is displayed in an enlarged manner; an enlarge/reduce button  305  for changing the enlargement ratio used for displaying the preview images  101   g  to  101   j ; and a transmission button  306  for transmitting an image by using the transmission settings used for the preview image selected by using the selection frame  303 . 
     The user checks the preview display screen  30 , and operates a touch panel serving as an operation unit of the tablet terminal  3  in the following manner. The user selects one of the preview images  101   g  to  101   j  that has a resolution that the user considers to be appropriate by using the selection frame  303 , and presses the transmission button  306 . 
     The preview images are displayed on the display of the tablet terminal  3 , and thereby the preview images are enabled to be displayed in more detail than in the case of being displayed on the display  12  of the image processing apparatus  1 . This also allows selection of a preview image through the tablet terminal  3 , eliminating the need for an operation through the operation unit  13 .
