Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display technique for simultaneously displaying a plurality of images obtained by bracket photographing.

[0002]

2. Description of the Related Art There is a so-called bracket photographing in which photographing conditions such as an exposure condition are changed little by little to continuously photograph. This means that, for example, when it is difficult to determine the shooting conditions due to complicated light conditions, etc., the shooting conditions are automatically changed little by little and shooting is performed a plurality of times, from among the obtained shooting images, This is a photographing method in which a photographed image that is the same as or similar to that intended by the user is freely selected.

[0003] In the bracket photographing, generally, photographing conditions, steps (change amounts) of the photographing conditions, and the number of steps can be arbitrarily set. For example, an exposure condition is set as a shooting condition, and 0.6E
When V is set and the number of steps is set to 3, and bracket shooting is performed, the exposure condition is set to -0.6 EV,
Three photographed images photographed at 0 EV and +0.6 EV are obtained, and the user can select a photographed image that is the same as or close to the intended one.

The function of performing bracket photographing (hereinafter, simply referred to as a bracket photographing function) has been widely used in silver halide cameras in the past. However, with the spread of electronic cameras in recent years, it has been widely adopted in electronic cameras. It became so.
In particular, electronic cameras have a feature that silver halide cameras do not have, in which captured images can be freely deleted, so even if a large number of captured images are obtained by bracket shooting, unnecessary captured images can be easily deleted later. This is one of the functions that are more easily used than silver halide cameras.

In general, an electronic camera is provided with a liquid crystal display section on the back of the camera, and the liquid crystal display section can display a captured image for each frame or for a plurality of frames (for example, 3 × 3 frames). It is configured. Further, in an electronic camera having a bracket photographing function, a plurality of photographed images obtained by bracket photographing are configured to be simultaneously displayed, for example, a plurality of photographed images obtained by bracket photographing using exposure conditions and white balance conditions as parameters. When the captured image is displayed on the liquid crystal display unit, it is arranged and displayed so that the exposure condition in the horizontal direction and the white balance condition in the vertical direction are sequentially different. Such a display method is a display method that allows a user to simultaneously compare a plurality of photographed images having different photographing conditions and to more easily select a photographed image intended by the user.

[0006]

However, depending on the subject to be photographed and the step (degree of change) of the photographing conditions set at the time of bracket photographing, the difference between a plurality of photographed images displayed on the liquid crystal display unit is slight. In this case, there is a problem that it is difficult for the user to determine the shooting conditions. In view of the above, there is a method in which a character or the like indicating a photographing condition (exposure condition, white balance condition, or the like) is superimposed on each photographed image and displayed, but in this case, the character or the like hinders confirmation of the photographed image. There is a problem that it is difficult for the user to compare the captured images. In particular, since the liquid crystal display unit provided in the electronic camera is small, each captured image displayed on the liquid crystal display unit is small,
It is remarkable that characters and the like superimposed on it obstruct the confirmation of the photographed image.

) 12 is an interface for connecting the bus line 9 to each other.
Data can be exchanged with the SFDC 12.

The SSFDC 12 is a so-called smart media (smart media is a registered trademark of Toshiba Corporation). In this embodiment, a plurality of image data obtained by bracket photographing with an electronic camera is recorded. The I / F 6 provides an interface function for outputting image data and the like to an external device connected to the external output terminal 13, for example, a TV (television) or the like, and outputs image data and the like to the external device. Perform processing. still,
The output image data and the like are, for example, digital signals or NTSC (National Television S

When displaying the multi-image based on the image data of the multi-image on which the frame data is superimposed, a frame is attached around each image of the multi-image as an identification mark corresponding to the shooting condition ( This is data to be provided and displayed. Accordingly, the image data of the multi-image on which the frame data is superimposed is used to simultaneously display a plurality of images obtained by the bracket shooting and to provide an identification mark corresponding to the shooting condition for each of the plurality of images for display. Data.

Next, an example of the operation processing of the display device 1 having such a configuration will be described. This processing is executed by the CPU.
2 is executed by executing a control program provided therein. In this example, an example will be described in which nine image data recorded in the SSFDC 12 and obtained by bracket shooting are displayed on the LCD display 11 in 3 × 3 frames. It is assumed that the bracket photographing was performed by changing the exposure condition and the white balance condition in three steps.

First, when the SSFDC 12 is mounted by the user and the multi-display instruction of the nine image data obtained by the bracket photographing recorded on the SSFDC 12 is performed via the input instruction unit 10, the instruction is performed based on the instruction. Start display processing. The shooting conditions for bracket shooting at this time are, for example, three exposure conditions (+ 0.3E
V, 0 EV, -0.3 EV) and three white balance conditions (red shift, center, blue shift).

In the display processing, first, one image data is read out from the nine image data recorded in the SSFDC 12, and the photographing conditions are obtained from the photographing information added to the image data. Subsequently, a process of expanding the read image data by the JPEG processing unit 4 is performed, and a process of resizing the expanded image data by the image processing unit 8 is performed. To perform the image processing according to. In the resizing process, for example, when the display size of the LCD display 11 is 400 × 300 pixels, the image data is resized to about 123 × 90 pixels.

The processing for performing such expansion processing, resizing processing, and image processing relating to color and the like is also performed on the remaining eight image data, and the nine image data that have been subjected to these processing are moved to a predetermined position. Arrange to create image data of multiple images. Here, based on the shooting conditions of each image data acquired earlier, the exposure conditions are arranged in the horizontal direction so as to be sequentially different, and the white balance conditions are arranged so as to be sequentially different in the vertical direction. Create image data for the image. Subsequently, frame data is created based on the shooting conditions of each of the previously acquired image data, and the frame data is superimposed on the image data of the above-described multi-image. Output to 11 When the multi-image based on the image data of the multi-image on which the frame data is superimposed is displayed on the liquid crystal display 11, the frame data is composed of colors and brightness corresponding to shooting conditions around each image of the multi-image. It is created so that a frame to be displayed is provided and displayed.

As a result, a multi-image (3 × 3 frames) based on the nine image data obtained by the bracket photographing is displayed on the LCD display 11, and
A frame composed of colors and brightness corresponding to the shooting conditions is provided and displayed around each image.

FIG. 2A shows an example of the display screen of the liquid crystal display 11 at this time. Also,
FIG. 2B is a diagram showing shooting conditions corresponding to each image of the multi-image shown in FIG. In FIG. 1A, for convenience of explanation, the frame numbers (1 to 9) are shown at the upper left of each frame, but they are not actually displayed.

As shown in FIGS. 3A and 3B, the multi-image based on the image data of the multi-image on which the frame data is superimposed has the same white balance condition in the horizontal row direction. The exposure conditions are arranged so as to be different in order. The display conditions are displayed in 3 × 3 frames arranged so that the exposure condition is the same and the white balance condition is different in order in one column direction. A frame composed of the corresponding color and brightness is provided and displayed. For example, in the first frame, a frame 21 composed of colors and brightness corresponding to shooting conditions is provided around the image 20 and displayed.

However, in FIG. 3A, all the frames provided and displayed around each image are shown in the same manner due to space limitations. The brightness is displayed differently according to the shooting conditions. For example, the color of the frame of the image (first frame to third frame) of the +1 step (slightly reddish) white balance condition is displayed in red, and the image of the ± 0 step (center value) (the first frame) ~
The color of the frame of the third frame is displayed in green, and the color of the frame of the -1 step (slightly bluish) image (the seventh to ninth frames) is displayed in blue. When the exposure condition is +0.
The frame of the 3EV image (the first, fourth and seventh frames) is displayed with a bright frame brightness, and the ± 0EV image (the second, fifth and eighth frames)
Is displayed in the middle of the frame brightness, -0.3EV
(3rd, 6th, and 9th frames) are displayed with darker frame brightness. Therefore, for example, the frame of the third frame is displayed in dark red, the frame of the fifth frame is displayed in green of intermediate brightness, and the frame of the seventh frame is displayed in blue of bright brightness. .

Thus, even if the difference between the nine images displayed on the liquid crystal display 11 and obtained by the bracket photographing is slight, the color and brightness of the frame displayed around the image can be improved. Confirmation (see)
This makes it possible to determine the shooting conditions. Further, in this case, since characters or the like corresponding to the shooting conditions are not superimposed on each image, it does not hinder image confirmation.

On the other hand, FIG. 3C shows another display example. In FIG. 9C, the frame numbers (1 to 9) are shown at the upper left of each frame for convenience of explanation, but they are not actually displayed. In FIG. 6A, a frame is provided around each image as an identification mark corresponding to the shooting condition, and in FIG. 8C, bands are formed above and below each image as the identification mark corresponding to the shooting condition. It is provided and displayed. For example, in the first frame, bands 22 and 23 corresponding to shooting conditions of the image 22 are provided and displayed above and below the image 22. The bands corresponding to the shooting conditions of these images are obtained by creating band data instead of the frame data in the image processing unit 8.

In FIG. 3C, as in FIG. 3A, the upper and lower bands of each image are shown in the same manner due to space limitations. And the brightness are displayed differently according to the shooting conditions, and displayed so that the user can determine the shooting conditions by checking the upper and lower bands of each image. For example, when the white balance condition is +1 step (slightly reddish), the upper and lower bands of the image (first to third frames) are displayed in red, and the image is ± 0 step (center value). The colors of the upper and lower bands of the (first to third frames) are both displayed in green, and the upper and lower bands of the -1 step (slightly blue) image (the seventh to ninth frames) are displayed. Both colors are displayed in blue. However, when the exposure condition is an image (1, 4,
In the upper band of the (7th frame), the brightness of the band is displayed brightly,
The upper band of the image of ± 0 EV (the second, fifth and eighth frames) is displayed at an intermediate brightness level, and the upper band of the −0.3 EV image (the third, sixth and ninth frames) is the band. Appears dark. Therefore, for example, the upper band of the third frame image is displayed in dark red, the lower band is displayed in red, and the upper band of the fifth frame image is green having an intermediate brightness. , The lower band is displayed in green, the upper band of the image of the seventh frame is displayed in bright blue, and the lower band is displayed in blue. That is, the user can confirm the exposure condition by the band displayed on the upper side of each image, and can confirm the white balance condition by the band displayed on the lower side of each image.

As described above, even when a band is displayed instead of a frame as an identification mark corresponding to a photographing condition, the user determines the photographing condition of each image by checking the color and brightness of the band. be able to. In FIG. 9C, the same band (having the same color and brightness) as the upper band may be displayed as the lower band of each image. Alternatively, only the upper band may be displayed. Or
The upper and lower bands may be provided on the left and right sides of the image and displayed.

In the present embodiment, the form in which a frame or a band corresponding to the photographing condition is provided and displayed on the outside of each image has been described, but it is provided so as to cover the inside of the image or the outside and the inside. May be displayed. Further, in the present embodiment, a frame or a band is applied as an example of the identification mark. However, any other shape may be used as long as it does not hinder image confirmation. In addition, although the identification mark is displayed so that the color and brightness are different according to the shooting conditions, the identification mark may be displayed so that the shape of the identification mark differs according to the shooting conditions. The identification mark may be displayed so that the combination of the shape, color, and brightness of the identification mark is different depending on the condition.

Further, in this embodiment, a mode in which a plurality of images obtained by bracket photographing using both the exposure condition and the white balance condition as parameters are displayed, but either one of the exposure condition and the white balance condition is displayed. The present invention may be applied to a case where a plurality of images obtained by bracket photographing using only parameters as a parameter are displayed.

In this embodiment, the multi-display mode is shown in which the exposure conditions are arranged in the horizontal direction so as to be sequentially different and the white balance conditions are sequentially arranged in the vertical direction so as to be different. Alternatively, the display may be arranged so that the white balance conditions are sequentially different in the horizontal direction, and may be arranged so that the exposure conditions are sequentially different in the vertical direction so as to perform multi-display. Although the number of images to be multi-displayed is shown by nine,
The number of images is not limited to this.

In this embodiment, the multi-image image data in which the frame data (or the band data) is superimposed is output to the liquid crystal display 11, but this is connected to the external output terminal 13. External device (for example, T
V, etc.) and may be displayed on the display screen of the external device.
