On the screen, operation buttons of a main scan button 201 and an end button 202 for ending the image are arranged, and can be selected by the keyboard 103 and the mouse 104.

The overall sequence of image capturing by the scanning camera 10 configured as described above will be described with reference to the flowchart shown in FIG. The imaging processing procedure described below is based on the control program stored in the PC 100 and the floppy disk drive (FDD) 1
05, which is a medium loaded in a floppy disk (F
D) It is executed based on a program having an operation procedure and a function written in 110.

With the main power switches of the camera 10 and the PC 100 turned on, the execution of the imaging routine is started (step S1). Subsequently, initialization of hardware and software initial positions and parameter setting values is performed (step S2). Here, the initial scanning position, no trimming area as trimming (capture of all areas), a position based on AF information as a focus position, a value determined according to AE information as an aperture value / integration time value, and no correction as an integration correction time The value of the,
A predetermined value higher than the prescan is set as the resolution, and a fixed rough value which is the first resolution is set as the prescan resolution.

Next, it is determined whether there is an operation input from the operation panel section 400 or the display panel section 300 (step S3). If there is no operation input, the process returns to step S3. When an operation is input, a process corresponding to each operated operation command to be described later is performed (steps S4 to S10, steps S21 to S23).
That is, in the operation command processing described above, steps S4 to S4 are executed.
After any of S10 is performed, the display panel unit on the display is re-displayed, and then, the process returns to step S3. If none of S4 to S10 is performed, the process goes to S, and any one of steps S21 to S23 can be performed. Thereafter, the process returns to step S3.

It is to be noted that the trimming in S10 can be individually set for the image, and that information is also managed as fetch information. However, the trimming information is carried over to the next prescan image. In other words, the trimming is set first, and if there is no change, the same trimming instruction is displayed for successive pre-scan images, but the change can be made for individual images.

Here, each operation command to be set and operated as shown in FIG. 4 will be described.

End command (step S4): By operating the button 402 in the operation panel unit 400 shown in FIG.
This sequence ends.

Prescan (Step S5): Button 4
By the operation of 01, an image is taken in at a predetermined rough first resolution that can be roughly understood according to the set shooting information, a plurality of the taken images and the shooting information are displayed in association with each other, and one of them is further displayed. Manage to be selectable. However, the capture range is the entire area, and trimming only displays the range frame.

Focus setting (step S6): The imaging optical system 13 is moved in the direction of the optical axis in accordance with the operation of the operation switches 10A to 10C for setting the focus of the camera or the buttons 411 to 413 on the display. Infinite, close or AF depending on the button or switch pressed
The focus position of the imaging optical system changes according to the signal, and the focus position of the lens is output as information.

Integration time correction (step S7): button 4
In accordance with the operation of the buttons 21 to 423, the correct exposure is set to +/- or the correction amount 0 is set.

Setting of integration time (step S8): button 4
The integration time is set according to the button operation of 31 to 433. Also, the setting according to the AE information is enabled.

Aperture value setting (step S9): An aperture value can be set according to a button operation. Also, the setting according to the AE information is enabled.

Here, with respect to the integration time setting in step S7 and the aperture value setting in step S9, if both are set by AE information, the optimum aperture and integration time are set based on the AE information, and only one of them is set. If AE is set by AE, it changes in conjunction with the other so that the AE setting becomes optimal as the exposure state, and if both are not set by AE, It will now follow the user's settings, not the exposure.

Trimming (step S10): In the image display unit 200 shown in FIG. 3, a trimming instruction is directly given to the captured and displayed image with a mouse or the like to set a trimming range frame. The image after the trimming is set inherits the trimming range frame according to the trimming. However, the setting of the trimming range frame can be arbitrarily changed for each image, and the trimming information is stored as capture information associated with the image. In addition,
In each of the above processes, some change is made to the display (such as a change in a numerical value), so that a new screen after the setting process is displayed again (step S11).

Main scan (step S21): a prescanned image, which is arranged in one selected from a plurality of prescanned images displayed in the display frame portion of the image display unit 200 shown in FIG. Full scan button 2
In response to the selection operation of 01 with the mouse 104, the image is again captured and displayed at the second resolution, which is a high resolution, according to the set photographing information. Save operation is enabled simultaneously with the display. The number of display portions of the captured image after the main scan is one, and a plurality of the images are not arranged at the same time.

End of image (step S22): The end operation of the image is performed in response to the operation of the end image button 202 arranged on the display frame portion of the image display unit 200 shown in FIG. The information associated with the image information is deleted by this end operation.

Resolution setting (step S23): The resolution is directly input or the selection is input by a pull-down menu.

Next, details of the sequence of the prescan (step S5), which is a subroutine in FIG. 4, are shown in FIG.
This will be described with reference to the flowchart shown in FIG. The pre-scan is performed by operating the pre-scan button 401 of the operation panel unit 400 on the display shown in FIG. 3 or the pre-scan button 10P arranged on the camera 10.
It is started in response to the operation of.

First, a prescan sequence is started (step S31). Then, the photographing conditions of the camera such as the focus position and the aperture value are set, and the operation panel unit 400
(Step S32). Further, the integration time and the integration time correction information at the time of the pre-scan are set according to the values set in advance on the operation panel section 400 (step S33). In addition, capture conditions such as resolution and trimming are set (step S34). Here, since the trimming information and the resolution information previously set in the operation panel unit 400 and the previous image are not used except during the main scan, they are temporarily replaced with information unique to the prescan. As for the trimming area, no trimming is initially set, and the trimming area can be changed and set by operating the mouse 104, and the trimming frame area set immediately before is set for display. Further, the resolution is temporarily set to a fixed value so that the image can be recognized when the image is later selected.

While the image is being captured under the above setting conditions, the simultaneously captured image is displayed (step S3).
5). The displayed image is captured based on information other than the resolution and the trimming information, for example, an aperture value, a value related to integration time, and a focus position, so that an actual image can be understood. After the display of the image display in step S35 is completed, the prescan subroutine sequence is terminated and the process exits (step S36).

Next, the sequence of the main scan (step S21), which is a subroutine in FIG. 4, will be described with reference to the flowchart shown in FIG.

The main scan is performed by pressing the button 2 of the prescan image display unit 200 arbitrarily selected by the user from a plurality of image displays on which each prescan image shown in FIG. 3 is displayed.
The process starts with 01, and is basically performed in a state where the set capture information is taken over.

First, the main scan sequence is started (step S41). Next, it is determined which one of the plurality of prescan images is selected (step S42). Then, condition data such as a focus position and an aperture value of the selected prescan image at the time of prescan, and data of integration time information according to the integration time and integration time correction information at the time of prescan are transmitted from the PC to the camera. (Step S43). Then, the image capturing conditions such as the trimming information at the time of pre-scanning sent from the PC are automatically set on the camera side (step S).
44). The captured information is displayed in the frame portion of the image to be captured, and at the same time, the capturing of the image is started and the captured image is displayed (step S45). After the image capturing is completed, it is confirmed whether or not to save (step S4).
6). In step S46, when saving, a save process is performed by instructing a file name or the like (step S47).
If the data is not to be stored, the process proceeds to the next step, and the sequence ends to exit (step S48).

As described in the above embodiment, the pre-scanned image of the object captured under each of a plurality of different conditions is first displayed as a rough image of the first resolution, and is displayed at a higher resolution than the first resolution. When the main scan is performed at the high second resolution, the best / desired image is confirmed from the pre-scanned images, and the desired image is automatically designated on the display by operating the mouse 104 or the like as the selecting means. The shooting conditions for that image are set in the image, and you can capture the image under the conditions you want to capture without having to set the capture conditions again. Can be.

In the image capturing device of the present embodiment, the AF
It is also possible to substitute the AE function with a line sensor. The imaging conditions can be changed intentionally,
Any electronic imaging camera having a display unit capable of displaying a plurality of captured images for each set condition can be applied not only to a scanning camera using a line sensor. Also, the same condition setting and display method as in the present embodiment can be easily applied to an image reading scanner or the like that reads an original or the like instead of a camera.

In the present embodiment, as shown in FIG. 3, a plurality of prescanned images are partially overlapped and displayed. However, a display method such as arranging the prescanned images so as not to overlap is not limited to this.

The form of the image display content is not limited to the present embodiment, and it is sufficient that the captured image is associated with the imaging condition and can be recognized without displaying each information at the same time.

Also, it is possible to set in advance the capturing conditions (focus, aperture value, integration time correction value, etc.) and automatically capture a plurality of prescanned images according to each setting.
