Further, the control unit 40 includes a memory for work of the CPU and a flash memory storing each control program executed by the CPU.

Here, a detailed configuration of the control unit 40 will be described. FIG. 5 shows a control unit 40 realized by the CPU.
FIG. 2 is a block diagram showing a functional configuration of the embodiment.

As shown in FIG. 5, the control section 40 is a control mechanism of the general digital camera 1 and has a luminance determination section 4 for setting an exposure control value (shutter speed (SS)).
01, shutter speed setting unit 402, and scene determination unit 4
03, a memory 404, and an image determination unit 405.

The luminance judging section 401 judges the brightness of a subject in an imaging standby state by using an image captured by the CCD area sensor 303 every 1/30 second. That is, the luminance determination unit 401 determines the brightness of the subject using the image data sequentially and renewedly stored in the image memories 209a and 209b.

The luminance judging unit 401 is provided with an image memory 209
Each of the storage areas a and 209b is divided into nine blocks, and luminance data representing each block is calculated using pixel data of a G (green) color component included in each block.

The shutter speed setting unit 402 sets a shutter speed (integration time of the CCD area sensor 303) SS based on the result of the brightness determination by the brightness determination unit 401. The shutter speed setting unit 402 has a table relating to the shutter speed SS.

The shutter speed SS is initially set to 1/128 second when the camera is started, and in a shooting standby state,

Further, the control unit 40 sets "short luminance scene", "medium luminance normal scene", "medium luminance scene" in order to set an appropriate shutter speed SS, perform γ correction, and perform filtering correction described later in accordance with the shooting scene. A scene determination unit 403 that determines four types of shooting scenes, a “luminance backlight scene” and a “high brightness scene”, is provided. "Low brightness scene"
Normally, this is a scene that requires auxiliary light using a flash, such as indoor shooting or nighttime shooting. A “medium-luminance normal scene” is one in which illumination light (including natural light and artificial light) for the main subject is normal and This is a scene that can be photographed without auxiliary light because its brightness is appropriate. The “medium brightness backlight scene” is a scene in which the overall brightness is appropriate, but the flash light is preferable because the illumination light for the main subject is backlight, and the “high brightness scene” is, for example, a clear sea scene. It is a very bright scene like shooting at a ski resort. Then, the determination result in the scene determination unit 403 is stored in the memory 404.

Further, the control unit 40 determines that the captured image is a normal photographed image of a landscape, a person, or the like (hereinafter, such a captured image is referred to as a natural image). (Hereinafter, an image similar to a binary image of this type is referred to as a character image).

The image determination unit 405 is provided with an image memory 209
a, a histogram of the luminance data at each pixel position is created based on the pixel data constituting the captured image stored in 209b, and the content of the captured image is determined based on the histogram. In general, a histogram of luminance data of a captured image is a so-called one-peak distribution having a single peak value with a small deviation of the luminance distribution in the case of a natural image. In the case of a character image, the luminance distribution is biased in each of a white background portion and a black character portion, resulting in a two-peak distribution. Therefore, the image determination unit 40
Reference numeral 5 indicates whether the captured image is a natural image or a character image by determining whether the histogram of the luminance data of the captured image has a single-peak distribution but a two-peak distribution. Then, this determination result is stored in the memory 404.

Further, the reproduced image generation unit 409 sequentially generates reproduced images according to index numbers described later, and causes the display unit 10 to display the reproduced images.

The filter unit 406 corrects the image quality of the contour by correcting a high frequency component of an image to be recorded by applying a predetermined digital filter. The filter unit 406 includes five types of digital filters, a digital filter that performs standard contour correction, and two types of digital filters that enhance the contour and two types of digital filters that weaken the contour with respect to the standard contour correction. It has.

The recording image generation unit 407 is provided in the image memory 20

A thumbnail image is generated and recorded on the memory card 8.

The recording image generation unit 407 reads out all pixel data from the image memories 209a and 209b, and applies a predetermined compression to these pixel data by a JPEG method such as two-dimensional DCT (discrete cosine transform) and Huffman coding. Processing is performed to generate image data of the compressed image, and the compressed image data is recorded in the image area of the memory card 8.

In the photographing mode, when the photographing is instructed by the shutter button 9 in the photographing mode, the control unit 40 displays the thumbnail image of the image taken into the image memory 209a (or 209b) after the photographing instruction and the compression setting slide switch 1
When the compression mode is set in step 2, a compressed image compressed by the JPEG method is generated. Then, both images are stored together with information such as a file name, tag information related to a captured image, a frame number, an exposure value, a shutter speed, compression / non-compression, a shooting date, flash on / off data at the time of shooting, scene information, and an image determination result. The data is stored in the memory card 8.

FIG. 6 is a diagram showing a memory map relating to information stored in the memory card 8.

In other words, it is possible to perform a print preview when performing index printing based on the index print information. Also,
Since the index number included in the index print information is a number indicating the arrangement order in the index print, if the captured images are displayed in the order of the index numbers, the arrangement order of the captured images in the index print can be confirmed. Become.

The reproduced image generation unit 409 displays the captured images in the order of the index numbers by outputting the captured images to the VRAM 210 based on the index numbers included in the index print information. Therefore,
Before the print data generation unit 411 outputs the print data for the index print, the user can check the print contents in the index print (especially, check the arrangement order in the index print).

The index numbers are determined according to the order in which the user has selected the photographed images for performing the index print. Further, the user can change the index number later. The user selects an image or changes the index number by operating the operation unit 2.

When numbers are assigned to the rightmost divided portion, the process moves down by one stage and numbers are similarly assigned from the left end to the right end. As a result, the number u of the divided portion at the lower right corner is a value obtained by subtracting 1 from the square value of the number of divisions d of each side.

In step S32, the horizontal position Sx and the vertical position Sy of the divided portion are obtained, and the horizontal length m and k of the k-th page are obtained as shown in FIG.
The vertical length n of the page is obtained. The position Sx in the horizontal direction of the divided part can be determined by obtaining the remainder obtained by dividing the number u of the divided part by the number of divisions d, and the position Sx in the vertical direction can be determined.
y can be determined by obtaining a quotient obtained by dividing the number u of the divided portion by the number of divisions d. The lengths m and n of the k-th page in the vertical and horizontal directions can be obtained from the print size of the print information stored in the memory card 8.

In step S33, a bitmap image in a predetermined range in the horizontal and vertical directions is stored in the image memory 209a on the k-th page of the print content. When this step S33 is first executed, since the division number d = 1, the entire first page (the number of pixels P in the horizontal direction and the number of pixels Q in the vertical direction) is the display range as shown in FIG. It is determined as a bitmap image and stored in the image memory 209a.

In step S34, the bitmap image stored in the image memory 209a is reproduced and displayed. The bitmap image within the range determined in step S33 is displayed on the display unit 10, and a print preview is performed. be able to. The details of this process will be described later.

In step S35, it is determined whether or not the UP switch 6 has been pressed, and if "YES", the flow proceeds to step S351 shown in FIG.
If "O", the process proceeds to step S36. In step S36, it is determined whether or not the DOWN switch 7 has been pressed. If “YES”, the process proceeds to step S361 shown in FIG. 12, while if “NO”, the process proceeds to step S3.
Go to 7.

In step S351, it is determined whether or not the FL mode setting switch 11 has been pressed when the UP switch 6 has been pressed.
On the other hand, if “NO”, the process proceeds to step S353.
Proceed to.

When the process proceeds to step S352, the process for enlarged display of the content displayed on the display unit 10 is performed. In step S352, the number of divisions d is incremented by one, and the divisional part number u is set to 0. That is, the process of step S352 is a process for increasing the enlargement ratio of the image portion to be displayed by increasing the number of divisions d, thereby performing the enlarged display of the image portion on the display unit 10.

When the process proceeds to step S353,
This is a process for performing scroll display of a display portion or scroll display of a page. In step S353, the number of divisions d
Is determined to be 0, and if “d = 0”, steps S357 to S35 are performed to perform page scrolling.
9 is performed. If “d = 0” is not satisfied, the processing of steps S354 to S356 is performed in order to scroll the enlarged image portion to another portion.

In step S361, it is determined whether or not the FL mode setting switch 11 has been pressed when the DOWN switch 7 has been pressed. If "YES", the process proceeds to step S362, while if "NO", the process proceeds to step S362. Step S3
Proceed to 64.

When the process proceeds to step S362, the process for reducing the content displayed on the display unit 10 is performed. In step S352, it is determined whether or not the number of divisions d is 0. If "d = 0", there is no need for reduction, and the process returns to step S35. If "d = 0", reduction display is performed. In order to perform this, the value of the number of divisions d is decremented by 1 and the number u of the divided parts is set to 0. That is, the process of step S363 is a process for reducing the enlargement ratio of the image portion to be displayed by reducing the number of divisions d, thereby performing reduced display of the image portion on the display unit 10.

When the process proceeds to step S364,
This is a process for performing scroll display of a display portion or scroll display of a page. In step S364, the division number d
Is determined to be 0, and if “d = 0”, steps S368 to S37 are performed to perform page scrolling.
0 processing is performed. If “d = 0” is not satisfied, the processing of steps S365 to S367 is performed in order to scroll the image part displayed in an enlarged manner to another part.

Therefore, when the print preview image is displayed on the display unit 10, the contents of the screen displayed by the user performing a predetermined operation are enlarged or the enlarged display part is moved to another part. You can do it.

That is, if the user presses the UP switch 6 without pressing the FL mode setting switch 11 after previewing the entire page, the setting is changed so that the next page is preview-displayed, and in step S32 The lengths of the next page in the horizontal and vertical directions are obtained, the bitmap image of the next page is stored and saved in the image memory 209a in step S33, and the reproduction and display processing of the next page is performed in step S34. It is. If the same operation as described above is performed after the preview display of the last page, the first page is preview-displayed.

After previewing the entire page, the user presses the FL mode setting switch 11
When the OWN switch 7 is pressed, the setting is changed so that the previous page is preview-displayed, the horizontal and vertical lengths of the previous page are obtained in step S32, and the previous page is determined in step S33. The bitmap image is stored in the image memory 209a, and the reproduction and display processing of the previous page is performed in step S34. If the same operation as described above is performed after the first page is preview-displayed, the last page is preview-displayed.

When the user presses the UP switch 6 while pressing the FL mode setting switch 11 after previewing the entire page, the setting is changed so that the page is enlarged and displayed, and the image is enlarged in step S33. The display range of the page is determined, and the bitmap image of the display range is stored and stored in the image memory 209a. And
In step S34, the bitmap image within the display range is enlarged and displayed. Each time the above operation is performed once, the number of divisions of the horizontal and vertical sides of the page is increased by one as shown in FIG. 17, and the number of divisions of the page is increased from one division to four divisions, nine divisions, and sixteen divisions. Divide and increase. And
By displaying one divided part at the upper left corner of the page on the display unit 10 on the full screen, the part is enlarged and displayed. Therefore, each time the number of divisions increases, the upper left corner of the page is enlarged and displayed.

When the user presses the DOWN switch 6 while holding down the FL mode setting switch 11 after previewing the entire page, the setting is changed so that the page is reduced and displayed, and the page is reduced in step S33. The display range of the page is determined, and the bitmap image of the display range is stored and stored in the image memory 209a. Then, the bitmap image within the display range is displayed in step S34. Each time the above operation is performed once, the number of divisions of the horizontal and vertical sides of the page is reduced by one as shown in FIG. 17, and the number of divisions of the page is reduced from 16 divisions to 9 divisions, 4 divisions, and 1 division. Divide and decrease. And
By displaying one divided portion at the upper left corner of the page on the display unit 10 on the full screen, a reduced display is performed. It should be noted that the display in a further reduced size than the state shown in FIG. 17D is not performed because it is rather difficult to confirm the print contents.

When the UP switch 7 is pressed without pressing the FL mode setting switch 11 after the enlarged preview of the divided portion of the page, not the entire page, the right divided portion is set to be previewed. Step S
At 33, the display range of the divided portion on the right side is obtained, and the bitmap image is stored in the image memory 209a. At step S34, the reproduction display process with the display range enlarged is performed. If the same operation as described above is performed after the rightmost divided portion is enlarged and previewed, the leftmost divided portion one line below is previewed. Furthermore, if the same operation as described above is performed after the preview of the divided portion at the lower right corner of the page is enlarged, the divided portion at the upper left corner of the page is previewed.

When the DOWN switch 6 is pressed without pressing the FL mode setting switch 11 after the enlarged preview of the divided portion of the page, not the entire page, the setting is made so that the divided portion on the left side is previewed. In step S33, the display range of the divided portion on the left side is obtained, and the bitmap image is stored in the image memory 209a.
In step S34, a reproduction display process in which the display range is enlarged is performed. When the same operation as described above is performed after previewing the leftmost divided portion, the rightmost divided portion on one line is previewed. Further, when the same operation as described above is performed after previewing the upper left corner of the page, the lower right corner of the page is previewed.

When the shutter button 9 is pressed after the end of the reproduction display processing in step S34, the print preview processing ends as shown in step S37, and the process exits from this processing routine.

Next, the process of reproducing and displaying the bitmap image in the image memory 209a in step S34 will be described with reference to the flowchart of FIG.

First, in step S400, the number P of pixels in the horizontal direction and the number Q of pixels in the vertical direction of the bitmap image stored in the image memory 209a are obtained, and the number of pixels in the horizontal direction that can be displayed on the display unit 10 is obtained. The number of pixels S and the number of pixels T in the vertical direction are obtained. For example, when the bitmap image stored in the image memory 209a is an image as shown in FIG. 20, P, Q are set as the number of pixels in the horizontal and vertical directions according to the print size.
To get. Also, the display unit 10 composed of an LCD or the like.
Since the number of pixels in the horizontal direction and the vertical direction that can be displayed is known as shown in FIG. 21, the number of pixels S and T in each direction can be easily obtained.

In step S401, the number of horizontal pixels P of the bitmap image is larger than the number of horizontal pixels S of the display unit 10, or the number of horizontal pixels Q of the bitmap image is It is determined whether the number of pixels is larger than the number T of pixels in the horizontal direction. If both the number of pixels in the horizontal direction and the number of pixels in the vertical direction of the bitmap image are smaller than the number of pixels in the horizontal direction and the vertical direction of the display unit 10, the process proceeds to step S413, and the bitmap image shown in FIG. The entire image is displayed on the display unit 10, and this routine ends. On the other hand, if either the horizontal direction or the vertical direction of the bitmap image is larger than the display unit 10, it means that the size of the bitmap image exceeds the image size that can be displayed on the display unit 10. The image compression is performed to the image size that can be displayed by the above processing.

The image size is compressed by, for example, extracting grid points using a grid. The grid interval is the same in the horizontal and vertical directions.

In steps S402, S403, and S404, the grid interval G is set so that the compressed image does not protrude beyond the displayable range on the display unit 10. That is, in step S402, it is determined whether the ratio of the number of pixels of the bitmap image to the displayable range on the display unit 10 is larger in the horizontal direction or the vertical direction, and it is determined that the ratio in the horizontal direction is larger. In step S403, the grid interval G is set so that the horizontal direction of the bitmap image falls within the displayable range of the display unit 10. On the other hand, if it is determined that the vertical direction is larger, the process proceeds to step S404. , So that the vertical direction of the bitmap image falls within the displayable range of the display unit 10.
Is set.

FIG. 22 is a diagram showing the concept of the reproduced image generation processing. By setting the grid interval G, FIG.
As shown in FIG. 22B, grid points with a grid interval G are set for the 0 bitmap image.

Next, in step S405, FIG.
As shown in (a), the display unit 10 is stored in the image memory 209b.
An image area having the number of pixels in the horizontal direction and the vertical direction in is secured. The image area of the image memory 209b is
An image area for generating a bitmap image to be displayed on the display unit 10.

Here, the color model of each bitmap image is an RGB color model, and the color value (R, G, B) = (r, g, b) at each pixel is represented by RGB (r, g, b).
b).

Each pixel included in the image area secured in the image memory 209b has RGB (0, 0,
(0,0) is set to black. In other words, step S
Step 405 corresponds to storing a bitmap image in which each pixel value is black in the image memory 209b.

Next, in steps S406 to S411, as shown in FIG. 22, grid points at the grid interval G are sequentially extracted from the bitmap image in the image memory 209a and overwritten on the bitmap image in the image memory 209b. The color information about the last grid point is stored in the image memory 209.
When writing to the corresponding pixel of b, the image memory 209a
Has been generated in the image memory 209b for the bitmap image stored in the image memory 209b.

The pixels not overwritten in the image memory 209b remain as they are in the compressed bitmap image as black as shown in FIG. Therefore,
Even when the compressed bitmap image is displayed on the display unit 10, the part that has not been overwritten is displayed as black.

Finally, in step S412, the compressed bitmap image generated in the image memory 209b is displayed on the display unit 10, and this routine ends.

As described above, the digital camera 1 according to the present embodiment is configured to be able to output print data based on a photographed image, and to output a print image based on the set print contents. In addition to being able to be displayed on the display unit 10 as a preview image, it is realized so that the preview image displayed on the display unit 10 can be enlarged and displayed. For this reason, even if the resolution gap between the display unit 10 and the printer device is large, it is possible to check in advance the detailed image portion when printing by enlarging the display content. In addition, for example, even when a print preview in which a plurality of similar images are arranged is displayed in an enlarged manner, the similar images can be easily distinguished from each other.

Further, the digital camera 1 has an operation section 250 formed by a plurality of switches as operation input means. Based on input information inputted by the user via the operation section 250, the enlargement ratio of the preview image is increased. Is changed so that the preview display can be performed at a magnification desired by the user.

When the print content covers a plurality of pages, the digital camera 1 is configured to continuously generate a preview image for each page and sequentially display the preview images on the display unit 10. The operation for displaying the preview image is simplified, and the print contents can be easily and quickly confirmed.

Further, since a page to be displayed as a preview image is changed based on input information input by the user via the operation unit 250, a preview display of a page desired by the user can be performed. It is realized as follows.

Next, referring to the flowcharts of FIGS. 14 to 16, a detailed processing procedure in the case of performing not the print preview but the reproduction and display processing of the photographed image (step S5) in the flowchart of FIG. 9 will be described. When the CPU functioning as the control unit 40 performs the following processing, the function as the above-described reproduced image generation unit 409 is realized.

First, in step S51, a selection screen is displayed on the display unit 10 of the digital camera 1. As an option,
"1: Frame number order, 2: Index print order, 3:
Back "is displayed. The frame number order is a playback display in which images are displayed in the order of frame numbers from among a plurality of captured images stored in the memory card 8, and the index print order is a playback display in which images are displayed in the order of the index numbers of the index print. is there. Note that when the user presses the shutter button 9, one of these options is determined. In the initial state, the frame number order is selected.
By pressing the OWN switch 6, an arbitrary option can be set to a selected state.

Then, in step S52, it is determined whether or not the shutter button 9 has been pressed in a state where "order by frame number" has been selected, and if "YES", the process proceeds to step S53.
After performing the frame number order image reproduction and display processing at, the process exits this routine.

Also, in step S54, when the "index print order" is selected, the shutter button 9
It is determined whether or not has been pressed, and if "YES", the index print order image reproduction and display processing is performed in step S55, and then this routine is exited.

Further, in step S56, it is determined whether or not the shutter button 9 has been pressed with "return" selected, and if "YES", the process exits this routine. On the other hand, if there is no input, step S51
Returns to the state of waiting for input from the user, and loops steps S51, S52, S54, S56.

Next, the details of the frame number order image reproduction / display processing will be described with reference to the flowchart of FIG. The reproduction display process is a process of sequentially displaying captured images in accordance with the image capturing order.

First, in step S531, it is determined whether or not one or more photographed images are stored in the memory card 8. If no photographed image exists in the memory card 8, it means that photographing has not been performed yet, and since there is no image to be reproduced and displayed, this processing routine is exited. On the other hand, if at least one image is stored in the memory card 8, the process proceeds to step S532 to continue the reproduction display process.

In step S532, the frame number t of the image to be reproduced and displayed is initially set to "0". Further, the maximum frame number L is obtained by checking all the tag information recorded on the memory card 8.

Then, in step S533, it is searched whether or not the image of the frame number t is stored in the memory card 8. If the image is stored, the reproduction and display processing of "image t" is performed in step S534. At 10, a captured image corresponding to the file name "image t" is reproduced and displayed. on the other hand,
If the frame number has not been stored, the process proceeds to step S538 to increment the frame number by one, and repeats the processing from step S533 for the frame number (t + 1).

When the user presses the UP switch 7 after the end of the reproduction display processing in step S534, the process proceeds to step S534.
Proceeding to 538, the frame number is incremented by one,
Similar processing is repeated for the image whose frame number has been increased by one from step S533. The frame number L whose frame number t is the maximum by the increment in step S538
If it has become larger, the flow advances to step S543 to set the frame number t to 0. That is, the UP switch 7 functions as an operation switch for changing the captured image reproduced and displayed in the order of increasing frame numbers. Is pressed, there is no captured image having a frame number higher than that, and the captured image corresponding to the first frame number 0 is reproduced and displayed.

When the user presses the DOWN switch 6 after the end of the reproduction display processing in step S534,
Proceeding to step S540, the frame number is decremented by one, and the same processing is repeated for the image whose frame number has been reduced by one from step S533. Step S540
If the frame number becomes smaller than 0 due to the decrement in the above, the frame number is set to the maximum frame number L in step S542.

When the shutter button 9 is pressed after the end of the reproduction display processing in step S534, this routine is exited.

Next, the details of the index print order image reproduction / display processing will be described with reference to the flowchart of FIG. The reproduction display process is a process of sequentially displaying captured images in accordance with the order of index numbers assigned to index print information.

First, in step S551, it is determined whether or not one or more photographed images are stored in the memory card 8. If no photographed image exists in the memory card 8, it means that photographing has not been performed yet, and since there is no image to be reproduced and displayed, this processing routine is exited. On the other hand, when at least one image is stored in the memory card 8, the process proceeds to step S552 to continue the reproduction display process.

In step S552, the index number i of the image to be reproduced and displayed is initialized to "0". That is, the image to be reproduced and displayed first is the image assigned to the index number 0 of the index print information included in the print information in the memory card 8. Further, by checking the print information recorded on the memory card 8, the maximum index number L
To get.

Then, the flow advances to a step S553 to search whether or not the image assigned to the index number i is stored in the memory card 8, and if the image is stored, the process proceeds to a step S553.
At 554, the frame number t of the image is checked, and step S5
At 55, a reproduction and display process of the image t is performed, and a captured image corresponding to the file name “image t” is displayed on the display unit 10. On the other hand, if the image corresponding to the index number i does not exist in the memory card 8, the index number is incremented by one in step S559, and in step S5
The same process is repeated for the image assigned to the index number (i + 1) from 53.

When the user presses the UP switch 7 after the end of the reproduction display processing in step S555, the process proceeds to step S555.
Proceeding to 559, the index number i is incremented by one, and the same processing from step S553 is repeated for the image assigned to the index number (i + 1) increased by one. If the index number i becomes larger than the maximum index number L due to the increment in step S559, step S559
At 561, the index number i is set to 0.

When the DOWN switch 6 is pressed after the end of the reproduction display processing in step S555, the processing proceeds to step S56.
At 2, the index number i is decremented by one,
The same processing from step S553 is repeated for the image assigned to the reduced index number. If the index number is less than 0 due to the decrement in step S562, step S56
4, the index number i is changed to the maximum index number L
To

When the shutter button 9 is pressed after the end of the reproduction display processing in step S555, this routine is exited.

The procedure of the reproduction and display processing of the image t in step S534 in FIG. 15 and the procedure of the reproduction and display processing of the image t in step S555 in FIG. 16 are the same as those in the reproduction and display processing shown in FIG. Can be applied. In this case, the image memory 2 shown in FIG.
09a corresponds to the memory card 8. Then, by applying the reproduction display processing of FIG. 13, the captured image can be displayed on the display unit 10 on the full screen. That is, in the present embodiment, when the captured image is reproduced and displayed, the captured image is displayed on the full screen so that the user can easily confirm the content of the captured image.
