[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a technique used in an electronic camera, and more particularly to a technique for increasing the degree of freedom of the size of a recorded image.
[0002]
[Prior art]
In recent years, there has been a remarkable spread of electronic cameras called digital cameras. This electronic camera generally captures a subject image and records image data representing an image of the subject image on a recording medium such as a memory card.
[0003]
Many electronic cameras have different image quality modes that combine the number of vertical and horizontal pixels of the image to be recorded or the size of the image and the compression ratio of the data compression applied to the image data representing the image. The image quality of the recorded image can be selected by the user selecting the image quality mode.
[0004]
FIG. 4 is a diagram illustrating an example of an image quality mode prepared for a certain electronic camera. In this electronic camera, there are four types of image quality modes that are broadly named TIFF, SHQ, HQ, and SQ. The figure will be described below.
The TIFF mode is an image quality mode for recording image data in a format according to an image format called TIFF (Tagged Image File Format). When this mode is selected, data compression is not performed on the image data. In this electronic camera, the user can select the number of pixels of the recorded image from the five types shown in the figure in the image recording in the TIFF mode. In the TIFF mode, data compression is not performed on the image data, so that although the image can be recorded with good image quality, the amount of image data representing one image is very large.
[0005]
Both the SHQ mode and the HQ mode are image quality modes for recording image data representing an image composed of all 2048 × 1536 pixels included in the image sensor provided in the electronic camera. Is a mode in which the data amount of the image data is compressed to about 1/3, and the HQ mode is a mode in which the data amount of the image data is compressed to about 1/8. Due to the difference in data compression rate, the image quality of the recorded image in the SHQ mode is better than the recorded image in the HQ mode.
[0006]
The SQ mode is an image quality mode in which the user can select the number of pixels of the recorded image and the compression rate of data compression applied to the image data. The user selects the number of pixels of the recorded image from the four types shown in FIG. Further, the compression rate of the data compression applied to the image data can be selected from about 1/3 or about 1/8, which is the same as in the SHQ / HQ mode.
[0007]
In the selection of the image quality mode, for example, when printing is premised, when an image recording with a high image quality is required, an image quality mode with a large number of pixels and a low data compression rate or no data compression is selected. On the other hand, an image quality mode with a small number of pixels and a high data compression rate is generally selected when image recording with a small amount of data is desired, such as when transmitting image data over a communication line with a small communication capacity. is there.
[0008]
[Problems to be solved by the invention]
In the conventional electronic camera, the aspect ratio of the recorded image, that is, the aspect ratio of the recorded image is a predetermined ratio regardless of the number of pixels of the selected image or the size of the image, for example, 3 in the aspect ratio: aspect ratio : The ratio is fixed to 4 or there is only a degree of freedom that the user can select from a few aspect ratios prepared, and an image can be recorded with an arbitrary aspect ratio with an electronic camera. There wasn't. For this reason, in order to obtain an image with a desired aspect ratio, the user has performed operations such as trimming a recorded image obtained by shooting after shooting.
[0009]
Further, in order to perform the trimming process on the recorded image data, there is an inconvenience that it is necessary to prepare a PC and image processing software as processing tools, and there is a financial burden for preparing these.
In view of the above problems, it is an object of the present invention to provide an electronic camera that can capture and record an image with an arbitrary aspect ratio.
[0010]

[0033]
The electronic camera in this embodiment includes the above-described components.
It is assumed that the image quality mode shown in FIG. 4 is prepared for this electronic camera, similar to the conventional electronic camera.
Next, FIG. 2 will be described. This figure shows an example of a screen displayed on the LCD display 16 provided in the electronic camera shown in FIG. Hereinafter, each screen shown in FIG. 2 will be described.
[0034]
(A) is an example of a setting screen displayed when the operation mode of the electronic camera is set to the shooting operation setting mode. This screen is displayed when “free size” that allows the user to arbitrarily set the number of vertical and horizontal pixels of the image is selected when the TIFF mode or SQ mode in the image quality mode described above is set for this electronic camera.
[0035]
In the figure, the number indicated by (1) is the remaining number of shootable images, which is a numerical value indicating how many more images can be recorded on the recording medium 11. The remaining possible number of shots is a value determined by the free capacity of the recording medium 11, the image quality mode, and the number of pixels of the screen to be recorded. A method for obtaining this value will be described later.
[0036]
(2) is a display showing the image quality mode when image recording is currently set for this electronic camera, and this screen shows that the SQ mode is selected.
(3) is a display showing the degree of data compression performed on the image data when image recording is performed in the SQ mode. In this electronic camera, for example, about 1/8 data compression is applied to the photographed image data. The character “standard” is selected when it is selected to be performed, and “high” is selected when image data is selected to be compressed with a lower compression rate than that of “standard”, for example about 1/3. The text “image quality” is displayed in this area.
[0037]
Numerals (4) and (5) indicate the number of pixels of the image currently set for the electronic camera when recording the image, (4) indicates the number of horizontal pixels, and ▲ 5 indicates the number of vertical pixels.
(6) is a display indicating that the number of horizontal pixels when recording an image can now be changed by operating the cross key switch of the input instruction acquiring unit 23. When this display is performed, if the button indicating the up / down direction of the cross key switch is operated, the number of horizontal pixels shown in (4) is increased or decreased according to the operation. If the button indicating the right of the cross key switch is operated here, the display of (6) moves from the periphery of the display of (4) to the periphery of the display of (5), and this time the vertical direction shown in (5). It is shown that the number of pixels can be changed. When the display of (6) is displayed around the display of (4), the button indicating the left of the cross key switch is operated, or the display of (6) is performed around the display of (5). If the button indicating the right side of the cross key switch is operated while the image is being displayed, the change of the image quality mode setting or the change of the data compression rate in the SQ mode displayed in (2) or (3) is performed thereafter. You can do this by operating
[0038]
In addition, (7) is an image portion recorded and included in an image having the number of pixels indicated by the numerals (4) and (5) in the current imaging screen displayed by the imaging device 2 displayed on the LCD display 16. This is a display of a colored (for example, blue) and translucent screen for clearly indicating to the user.
[0039]
The size of the entire screen shown in (a) is horizontal 2048 pixels × vertical 1536 pixels, and the aspect ratio of the LCD display 16 in the present embodiment is 3: 4. Is displayed. Here, since the current setting of the number of pixels in (4) and (5) is 1600 pixels in the horizontal direction × 1536 pixels in the vertical direction, both the left and right ends of the screen displayed on the LCD display 16 that are not recorded on the recording medium 11 are displayed. The screen shown in (7) is combined with the image and displayed on the part. If the width of this screen portion is changed immediately in accordance with the change in the number of pixels in (4) and (5), the range of the recorded image area can be recognized immediately, which is convenient.
[0040]
In the following description, when specifying the value of the aspect ratio of an image, a parameter K is used, and this value is indicated by a value obtained as a result of calculation of (vertical pixel count) / (horizontal pixel count). To do.
In (a), since the setting of the number of pixels in (4) and (5) is 1600 horizontal pixels × 1536 vertical pixels, the value of K at this time is 1536/1600 = 0.96.
[0041]
(B) shows a screen displayed on the LCD display 16 when the operation mode of the electronic camera is set to the photographing mode.
If the operation mode is set to the shooting mode when the shooting operation setting of the electronic camera is set as shown in (a), the current captured image (through image) by the imaging device 2 is displayed on the LCD display 16 as shown in (b). Is displayed. At this time, according to the setting shown in (a), the screen shown in (7) is synthesized and displayed for the left and right end portions of the through image that are not recorded. Since this screen is translucent, it is displayed so that the image of this portion of the captured image can be seen through. This screen portion synthesis process can be realized by, for example, a process for transparently synthesizing screen tones composed of single-color dots arranged at a uniform pitch as used in so-called shading.
[0042]
In addition, when the operation mode of the electronic camera is the shooting operation setting mode, if the display of (a) is superimposed on the through image as shown in (b) and displayed, the image recorded while viewing the through image This is convenient because the area range can be set.
(C) shows the screen display when the aspect ratio K of the recorded image determined by the number of pixels set in (4) and (5) of (a) is less than 0.75. Yes, at this time, the screen portion as shown in (7) of (a) is displayed as superimposed on the upper and lower ends of the through image.
[0043]
(D) shows that the electronic camera reads out image data recorded on the recording medium 11 and reproduced and displayed on the LCD display 16 when the shooting operation setting is set as shown in (a). The reproduced image is shown. In the present embodiment, when the aspect ratio of the LCD display and the recorded image does not match, priority is given to reproducing and displaying all of the recorded image, and a non-existent portion of the recorded image is monochromatic like a so-called blue background. The screen is filled with the display.
[0044]
(E) is a so-called LCD display 16 in which the electronic camera reads a plurality of images of image data that have been shot and recorded on the recording medium 11 when the shooting operation setting is set as shown in (a). A screen for displaying an index is shown. As shown in (e), the image (index image) displayed on the index display screen is such that the reproduced image of the entire display screen of the LCD display 16 shown in (d) is reduced.
[0045]
(F) is a through image display screen similar to (c), but when the through image is dark, that is, when the average of the luminance data of the pixels in the image data is small, the screen color of (7) is changed. For example, a bright color such as white, yellow, or pink is shown to improve the visibility of the presence or absence of a screen.
[0046]
Note that the screen (7) shown in FIGS. 2 (a), (b), (c), and (f) is set to the number of vertical and horizontal pixels and (4) and (5) in the original through image. When the number of vertical and horizontal pixels in the images match, that is, when the aspect ratios of the two match, they are not displayed on the LCD display 16 but are displayed when the aspect ratios of the two differ. In this way, the user can easily recognize that the electronic camera is set to record an image with an aspect ratio different from the normal one.
[0047]
Next, an example of a method for obtaining the remaining number of shootable images indicated by (1) in FIG.
When the image quality mode of the electronic camera is the TIFF mode, first, the following formula is calculated.
[0048]
n = (free capacity) / (number of pixels × 3 + header capacity)
Here, the free capacity and the number of pixels of the recording medium 11 are the number of pixels constituting the recorded image (the number of vertical pixels of the image × the number of horizontal pixels). “3” indicates that each pixel is expressed by RGB 3-byte data. The header capacity is a capacity of header information attached to the image data file recorded on the recording medium 11.
[0049]
The maximum natural number not exceeding the value n obtained by this equation is the remaining number of shootable images.
As a numerical example, when the free capacity of the recording medium 11 is 16777216 bytes (16 Mbytes), the number of pixels constituting the image is 2000 pixels vertically, 1000 pixels horizontally, and the header capacity is 15000 bytes, 2 <n (approximately 2 79) <3, and the remaining number of images that can be shot is calculated to be 2.
[0050]
When the image quality mode of the electronic camera is set to SHQ, HQ, or SQ mode and image data is subjected to data compression processing by the JPEG method, the following formula is first calculated.
n = (free space) / (number of pixels × 2 × compression rate + header capacity)
Here, “2” indicates that, in the image data after the data compression processing by the JPEG method, the luminance and the hue are expressed at a rate of 2 bytes of data for each pixel. The compression rate indicates the compression rate of data compression that can be set in the data compression processing by the JPEG method. In this electronic camera, when recording an image with “standard” image quality, 1/8, “high image quality”. A value of 1/3 is used when image recording is performed.
[0051]
The maximum natural number not exceeding the value n obtained by this equation is the remaining number of shootable images.
As numerical examples, the free space of the recording medium 11 is 16777216 bytes (16 Mbytes), the number of pixels constituting the image is 2000 pixels vertically, 1000 pixels horizontally, the header capacity is 15000 bytes, and an image with “high image quality” When recording, 12 <n (approximately 12.4) <13, and the remaining number of shootable images is calculated to be 12.
[0052]
Note that in the image data compression process, the image data is not necessarily compressed to the extent that the compression rate setting value is actually satisfied. You should do it.
The number of remaining shots that can be taken is obtained as described above.
[0053]
Hereinafter, control processing performed by the CPU 17 of the electronic camera shown in FIG. 1 will be described.
FIG. 3 is a flowchart showing the contents of the control process performed by the CPU 17. A series of processes shown in the figure is realized by the CPU 17 executing a control program stored in advance.
[0054]
FIG. 3A shows the contents of the shooting operation setting mode process. This process is started when the operation mode of the electronic camera is switched to the shooting operation setting mode by an operation performed on the input instruction acquisition unit 23, and then the operation mode is changed to a mode other than the shooting operation setting mode. Exit when switched.
[0055]
First, in step S101, an instruction is given to the display processing unit 14, and image processing for synthesizing (1) to (6) in the shooting operation setting screen shown in FIG. The composite image obtained by the processing is displayed on the LCD display 16.
[0056]
In S102, the operation content to the cross key switch of the input instruction acquisition unit 23 is acquired, and an instruction to change the display of the shooting operation setting screen to that based on the operation content is given to the display processing unit 14.
In S103, it is determined whether the image quality mode is instructed to be the TIFF mode or the SQ mode according to the operation content acquired in the previous step. If the determination result is Yes, the process proceeds to S104. If the determination result is No, the process proceeds to S109. Proceed with each.
[0057]
In S104, it is determined whether or not the setting when the image quality mode of the electronic camera is TIFF mode or SQ mode is set to “free size”. If the determination result is Yes, the process proceeds to S105. If the determination result is No, the process proceeds to S109. , Go on each.
[0058]
In S105, whether or not the aspect ratio K at the time of image recording obtained by setting the number of pixels acquired by the operation content acquired in S102 matches a predetermined ratio K0 (for example, 0.75). If the determination result is Yes, the process proceeds to S106, and if the determination result is No, the process proceeds to S109.
[0059]
In S106, it is determined whether or not the brightness (luminance) of the current through image, which can be grasped from the data obtained from the AF / AE / AWB data acquisition unit 19, is darker than a predetermined value. If Yes, the process proceeds to S108, and if No, the process proceeds to S107.
[0060]
In S107, as shown in (b) or (c) of FIG. 2, an instruction to perform image processing for superimposing and synthesizing the screen (7) on the through image is given to the display processing unit 14, and is performed in accordance with the instruction. The composite image obtained by the image processing is displayed on the LCD display 16 as a through image. After the completion of this process, the process returns to S101, the process of synthesizing (1) to (6) in FIG. 2 (a) is performed on this through image, and then the above-described process is repeated.
[0061]
In S108, as shown in FIG. 2 (f), the display processing unit 14 is instructed to perform image processing for superimposing and synthesizing the screen (7) using bright colors such as white, yellow, and pink. The composite image obtained by the image processing performed in response to the instruction is displayed on the LCD display 16 as a through image. After the completion of this process, the process returns to S101, the process of synthesizing (1) to (6) in FIG. 2 (a) is performed on this through image, and then the above-described process is repeated.
[0062]
In S109, the through image is directly displayed on the LCD display 16 without being subjected to image processing by the display processing unit 14. After the completion of this process, the process returns to S101, the process of synthesizing (1) to (6) in FIG. 2 (a) is performed on this through image, and then the above-described process is repeated.
[0063]
The above processing is the shooting operation setting mode processing.
Next, FIG. 3B will be described. The flowchart shown in the figure shows the processing contents of the shooting mode processing. This process is started when the operation mode of the electronic camera is switched to the shooting mode by an operation performed on the input instruction acquisition unit 23, and then the operation mode is switched to a mode other than the shooting mode. To finish.
[0064]
First, in S201, it is obtained by any one of S107, S108, and S109 in the shooting operation setting mode process of FIG. 3A, which is executed based on the current setting state of the shooting operation of the electronic camera. The display processing unit 14 is instructed to perform image processing for creating a through image similar to that to be displayed, and a composite image obtained by the image processing is displayed on the LCD display 16 as a through image.
[0065]
In S202, it is determined whether or not a first release, that is, a so-called half-press operation has been performed on the release button of the input instruction acquisition unit 23, and until this determination result is Yes, that is, until the first release is detected. The determination process in S202 is repeated.
[0066]
In S203, an instruction is given to the drive control unit 20, the drive motor 21 is controlled based on the data acquired by the AF / AE / AWB data acquisition unit 19, the position of the focusing lens 1 is moved, and the image sensor 2 is moved. AF control processing for appropriately forming a subject image formed on the light receiving surface is executed.
[0067]
In S204, an AE control process for giving an instruction to the imaging control unit 22 to control the imaging device 2 based on the data acquired by the AF / AE / AWB data acquisition unit 19 and appropriately setting the exposure is executed. .
In S205, it is determined whether or not a 2nd release, that is, a so-called full-press operation has been performed on the release button of the input instruction acquiring unit 23, and until this determination result is Yes, that is, until this 2nd release is detected. The determination process in S205 is repeated.
[0068]
In S <b> 206, a photographing process for recording image data representing a subject image formed on the light receiving surface of the image sensor 2 on a recording medium is executed.
In S207, an instruction is given to the AWB and γ correction processing unit 6, and automatic white balance processing based on the data acquired by the AF / AE / AWB data acquisition unit 19 is executed. Then, after the photographing process is completed, the process returns to S201, and the above-described process is repeated.
[0069]
The above processing is the shooting mode processing.
When the CPU 17 executes the control process shown in FIG. 3, the electronic camera shown in FIG. 1 can check an image with an arbitrary aspect ratio at the time of shooting and can take an image with the aspect ratio. It becomes like this.
[0070]
In addition, this invention is not limited to the Example mentioned above, A various improvement and change are possible.
For example, in the electronic camera described above, an instruction for the number of vertical and horizontal pixels for an image to be recorded on the recording medium 11 is obtained. Instead, the number of vertical and horizontal pixels constituting the image is changed as shown in FIG. The selection result selected by the user from the predetermined setting value as shown in FIG. 5 and the aspect ratio specification result of the image arbitrarily specified by the user can be acquired, and the vertical and horizontal pixels of the selected predetermined value are acquired. It is also possible to record on the recording medium 11 a partial image obtained by trimming from an image configured with the aspect ratio specified and including the widest area of the image before trimming.
[0071]
In addition, it is possible to specify an instruction for the number of vertical and horizontal pixels for an image to be recorded on the recording medium 11 beyond the number of pixels of the image obtained from the image sensor 2, and when such specification is made, interpolation processing between the pixels is performed. It is also possible to increase the number of pixels constituting the image and resize the image by the resize processing unit 7.
