Abstract

PROBLEM TO BE SOLVED: To set parameters matching the kind of a document without any trouble by preparing parameters corresponding to representative document kinds as fixed parameters. SOLUTION: When the device is actuated, a parameter setting part 3 loads default fixed parameter data (a) of a default fixed parameter data part 1 to fixed parameter parts (c-1) to (c-4). When a user specifies fixed parameter modification at the time of the actuation, the parameter setting part 3 loads fixed parameter data (b) set by the user to the fixed parameter parts (c-1) to (c-4). At this time, only the fixed parameters set by the fixed parameter data part 2 among (c-1) to (c-4) are overwritten and the parameters which are not set are the default parameters which are loaded previously.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image reading apparatus, more specifically, an image is read by optical or electrical means according to a command from an information processing apparatus such as a scanner, and the data is read by a communication function. The present invention is mainly intended to be applied to an image reading apparatus having a function of transferring information to an information processing apparatus, but is naturally applicable to an image reading apparatus having no communication function. The present invention relates to means for setting image reading conditions (parameters) in such an image reading apparatus.

[0002]

2. Description of the Related Art In a conventional image reading apparatus, reading conditions (parameters) at the time of reading an image, for example, when reading an image, read black and white inverted, read left and right inverted, or read gradation. For example, a reading condition such as reading only an image of 2 or 16 gradations or reading only a color image is set every time reading is performed. Further, even in a reading device having a function of storing parameters, an operation of reading a parameter stored at the time of execution and then reading an image is required.

[0003]

In the conventional method of setting the reading parameters, it is necessary to set the parameters every time reading is performed, and there is a high possibility that the reading will be performed with parameters that do not match the type of the original. Was.

[0004] The present invention has been made in view of the above-mentioned circumstances, and has a parameter corresponding to a representative document type as a fixed parameter in advance.
This makes it possible to set parameters suitable for the type of document without troublesome work.

Further, conventionally, it was not possible to change the parameters fixed in advance, and in such a case, it was necessary to set all the parameters. The parameter change function that changes parameters eliminates the need to save or load settings or parameters.

[0006]

According to a first aspect of the present invention, in an image reading apparatus, reading conditions for reading an image are fixed, so that parameters corresponding to representative document types are set in advance. By having the parameters as fixed parameters, it is possible to set parameters suitable for the type of document without troublesome work.

A second aspect of the present invention is characterized in that, in the first aspect of the present invention, the fixed reading condition can be changed by a user, and the fixed reading condition is set by a parameter changing function for changing the fixed parameter. Or, it eliminates the need to save and load parameters.

FIG. 1 is a block diagram for explaining an embodiment of the present invention. In FIG. 1, reference numeral 1 denotes a default fixed parameter data section, 2 denotes a user-set fixed parameter data section, and 3 denotes a parameter setting section. Reference numeral 4 denotes an image reading unit, reference numeral 5 denotes an image display unit, and default fixed parameter data (a) is fixed parameters set in advance on the present apparatus (image reading apparatus) 4 and user-set fixed parameter data (b ) Is arbitrary fixed parameter setting data that can be determined by the user.
The parameter setting unit 3 sets reading parameters for the image reading unit 4 and reads an image.
(C-1) to (c-5) indicate types of parameters that can be set, (c-1) to (c-4) are fixed parameters, and the user cannot change the values.
(C-5) is a variable parameter, the value of which can be changed by the user. Image reading unit 4
, Optically reads an actually set original and transmits image data to the host image display unit. Image display unit 5
Displays the image data transferred from the image reading unit 4 on a display.

When the apparatus is started, the parameter setting section 3 loads the default fixed parameter data (a) of the default fixed parameter data section 1 into the fixed parameter sections (c-1) to (c-4). When the fixed parameter change is specified by the user at the time of activation, the parameter setting unit 3 converts the user-set fixed parameter data (b) set by the user into (c).
-1) to (c-4) are loaded into the fixed parameter section. At this time, only the fixed parameters set in the user-set fixed parameter data part 2 out of (c-1) to (c-4) are overwritten, and the parameters not set are replaced with the default fixed parameters loaded earlier. Becomes The user selects one of the fixed parameters 1 to 4 or the user parameter and sets it in the image reading unit 4. Next, by the image reading command,
Image data is fetched from the image reading unit 4, and the fetched image data is displayed on a display by the image display unit 5.

(Embodiment 1) FIGS. 2 to 4 show an embodiment in which default fixed parameters (text, photograph 1, photograph 2, newspaper) are not changed. When you start up,
As shown in FIG. 2, "character" is automatically selected. This fixed parameter can be selected according to the original to be read. In FIG. 3, “Photo 2” is selected. These fixed parameters (text, photo 1,
The original reading conditions (parameters: black-and-white inversion, left-right inversion, 2 gradations, 16 gradations, etc.) for how to read those originals are predetermined in Photo 2 and Newspaper. It is assumed that a photograph in a document is read in gray scale. FIG. 4 shows an image obtained by displaying the image obtained when the photograph (image) portion A is read in gray scale on the image display portion 5. In this case, it appears that the portion A has gradation.

(Embodiment 2) FIGS. 5 to 8 are diagrams for explaining an embodiment in which a default fixed parameter is changed. User-set fixed parameter data as shown in FIG. Start the device by specifying. FIG. 6 is a diagram showing the display on the panel surface when the above-mentioned fixed parameter data is changed by the user in this way. In this case, the "characters",
"Picture 1" is changed to "Pa 1" and "Pa 2", respectively.
Parameters for reading those manuscripts (reading conditions)
Can also be changed.

FIG. 7 shows the panel surface after the fixed parameters (characters, photograph 1, photograph 2,...) Have been changed as described above, and “par 2” is selected in this state. FIG.
Is a diagram showing an image display when "PA2" is selected. In this case (in PA2), the condition is such that the image data is read in binary. Therefore, in FIG.
Part A is white.

[0013]

According to the first aspect of the present invention, parameters corresponding to representative document types are previously set as fixed parameters, so that parameters (document reading conditions) suitable for the document type can be set without any trouble. It becomes possible.

According to the second aspect of the present invention, since the fixed parameters can be changed by the user, the trouble of setting the parameters can be saved, and the setting errors are less likely to occur.
