Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to an electronic image pickup apparatus having a function of reproducing a picked-up image and displaying frame-by-frame.

[0002]

2. Description of the Related Art In recent years, electronic imaging devices called digital cameras have become widespread.

[0003] A subject image taken by a digital camera is formed on a CCD element and subjected to photoelectric processing. At present, some CCD elements have more than 1.4 million pixels.
High resolution shooting is now possible.

[0004] The video signal subjected to the photoelectric conversion processing is recorded on a memory card as digital data. The images recorded on the memory card are stored on the LC provided in the digital camera.
It can be played on a D display. As described above, the fact that a captured image can be reproduced on the spot is also a great attraction of a digital camera.

[0005] Further, in a digital camera, a frame can be advanced in order from the latest image while a captured image is displayed on a full screen on an LCD display.
In other digital cameras, a desired image can be selected from an index image from a plurality of reduced images, and the selected image can be displayed on a full screen.

However, reading an image to be displayed on a full screen (hereinafter, referred to as a "full image") requires, for example, several seconds, so that the user of the digital camera must wait while this full image is displayed.

The above-described technique of selecting a desired image from an index image and displaying a full image is a technique developed to minimize such a waiting time.
However, after selecting an image, it is necessary to wait for the reproduction and display of the full image. If it is desired to advance to the next image during the waiting time for displaying the full image, it is necessary to wait until the display of the full image is completed in order to confirm the next image.

In particular, in recent years, as the capacity of a memory card has increased, 200 or 300 images can be photographed with one memory card. Therefore, there is a strong demand for shortening the frame feed access time for each image. .

[0009]

In FIG. 3, the imaging lens system 20 provided in the projection 3 of the camera body 2 is provided with a diaphragm mechanism and a focus adjustment mechanism (not shown). The aperture mechanism and the focus adjustment mechanism are controlled by an aperture / focus control circuit 21. A subject image obtained through the imaging lens system 20 is formed on a CCD 22 (imaging device).

The CCD 22 photoelectrically converts the light intensity of the subject image and supplies the light intensity to the image pickup circuit 24 as image data. The imaging circuit 24 performs various image processing such as gamma correction processing, color separation processing, and white balance processing on the video data from the CCD 22 to convert the video data into a video signal in a predetermined color space.
AE (auto exposure), AF (auto focus), AWB
(Automatic white balance) is sent to the evaluation value generation circuit 25 and the display circuit 33.

This AE, AF, AWB evaluation value generation circuit 2
5 obtains values such as the brightness, focal length, and white balance of the subject image based on the output data from the CCD 22. Note that AE is an abbreviation of Automatic Exposure, which means an exposure mechanism that measures the luminance of a subject and automatically controls exposure. AF is Automatic Foc
The abbreviation for us means a mechanism for automatically controlling focus adjustment by electrical means. AWB is Automati
c Short for White Balance, which means a mechanism that automatically changes sensitivity and adjusts white balance.

The evaluation value by the evaluation value generation circuit 25 is
It is input to a controller (CPU) 26. When the shooting mode is set to auto, the controller 26
Is based on the evaluation value,
1 to obtain an appropriate focus by moving the imaging lens in the focus direction. Also, this controller 26
Calculates an aperture, a shutter speed, and an ISO sensitivity so that an appropriate exposure can be obtained based on the evaluation value.
4 is controlled.

The image data processed as described above is output from the image pickup circuit 24 to the display circuit 33, and is directly reproduced on the display unit 7 as a moving image. Further, based on the depression of the shutter button 12, the recording circuit 30 is activated, and the image from the imaging circuit 24 is divided into a full image and a still image data of a thumbnail image, and is mounted on the card control unit 31. Compress and record on a removable memory card.

(Control System of Image Reproduction and Frame Forward Function) Next, the reproduction function of the digital camera will be described with reference to the reproduction processing procedure shown in the flowcharts of FIGS. It is assumed that the number of images stored in the memory card in the present embodiment is 200. Also, in FIG.
Menu key 8, cross key 9, confirm key 1 shown in FIG.
The input interface 27 collectively includes various input means such as 0.
It is expressed as

When an image reproducing command is input through the input interface 27, the controller 26 operates the reproducing unit 32 shown in FIG. 3 to start a reproducing process (step S1). In this case, the image data recorded on the memory card is temporarily recorded on the built-in memory 34 via the card controller 31. Then, data is sequentially read from the built-in memory 34 to the reproducing unit 32.

In this reproduction process, first, the controller 26 obtains the number of images in the memory card, and assigns frame numbers sequentially from the oldest photographed image (step S2). In the present embodiment, the oldest captured image is assigned a frame number of “1”, and the newest captured image is assigned a frame number of “200”.

Next, the display circuit 33 starts the reproduction process of the thumbnail image with the newest frame number "200" (step S3), and then displays the thumbnail image (step S4). Then, reading of a full image corresponding to the same frame number as the currently displayed thumbnail image is started (step S5).

In the thumbnail image display processing, the thumbnail image data stored in the memory card is stored in the internal memory 34.
In the case where the read data is compressed data, the data is expanded and displayed on the display unit 7 after decompression processing (hereinafter, the processing from reading an image from a memory card to displaying it on the display unit is referred to as “read processing” ). This display is completed in the order of 1/100 second as described above, and a thumbnail image of 1/9 of the full image is displayed on the display section 7 as shown in FIG.
"0". In this case, the thumbnail image can be displayed in any size, not limited to 1/9 the size of the full image.

On the other hand, in order to read out the full image data, decompress it, and display it, a VRAM (video R
AM) takes several seconds to perform the reading process. Steps S6 to S12 are repeated until the reading processing of the full image data ends (step S12).

That is, the controller 26 detects whether or not the left and right keys of the cross key 9 have been operated until the reading of the full image is completed. When the right key is operated (step S6), the controller 26
Issues a command to the reproducing unit 32 to interrupt the reading process of the full image (step S7). Next, the frame number is incremented (the current frame number plus 1 is set as the selected frame number), and the process returns to step S3 (step S8).

That is, if a frame feed command is given during the reading of the full image, the display circuit 33
Immediately stops the reading process of the current full image.
Then, the thumbnail image corresponding to the incremented frame number is displayed (step S4), and the reading process of the full image corresponding to the same number is started (step S5).

When the left key is pressed (step S9), the frame number is decremented by the same procedure as that for the right key, and the process returns to step 3 (step S10).
S11).

On the other hand, if the reading of the full image is completed without operating the left and right keys (step S1).
2) The controller 26 displays a full image instead of a thumbnail image on the display unit 7 (step S1).
3).

Next, the controller 26 detects a predetermined input from, for example, the shutter button 12 or the zoom button 13 through the input interface 27 (see FIG. 4).
Step S14). Then, if there is a predetermined input, a photographing operation or a zoom operation of a displayed full image is performed by a predetermined operation, but the detailed description is omitted because it is not related to the gist of the present invention.

If there is no predetermined input in step S14, the controller 26 continues to display the full image even after the full image is displayed.
It is detected whether the left and right keys of the cross key 9 have been operated (steps S15 and S17). When any key is operated, the controller 26 increments (step S16) or decrements (step S18) the frame number, and returns to step S3 to display the next thumbnail image and read the full image. Start.

In this embodiment, in the frame feed operation,
A thumbnail image is displayed during a time-consuming full image reading operation, and the full image is displayed instead of the thumbnail image when the full image reading process is completed.

If an operation such as frame advance is performed during the reading of the full image, the reading of the full image is stopped at that point, and the thumbnail image corresponding to the frame output signal output last is displayed. To start reading processing of the full image corresponding to the thumbnail image.

According to such a configuration, there is an effect that frame advance can be performed at a high speed, and the user can confirm the image content with the thumbnail image.

In both the thumbnail image display and the full image display, if the image is the last image taken last, a warning is issued by flashing the frame number or changing the color or shape. Is preferred.

(Index Screen Forwarding Function) Next, a reproduction operation for accessing another screen by switching the index screen will be described with reference to FIGS. 5 (a) to 6 (e).

Have been assigned. Therefore, when the lower key of the cross key 9 is operated, the display switching instructing unit 36 detects the operation and controls the display circuit 33, and the display of the display unit 7 is changed to the frame number "as shown in FIG. 14 is switched to the index screen centering on the thumbnail image.

6 (b) to 6 (e) show the index screen (FIG. 5 (b) and FIG. 6 (a)) as the basic screen, and the up, down, left and right keys of the cross key 9. FIG. 9 shows a display after the operation when is operated.

When the right key is operated in a state where the index screen is displayed on the display unit 7 (FIG. 5B and FIG. 6A), the image designation unit 35 sets the image data in FIG. Then, the cursor at the frame number "14" is moved to the frame number "15" as shown in FIG. 6B, so that the thumbnail image of the frame number 15 can be selected. By operating the enter key 10 in this state, the operation after step S3 in FIG. 4 is executed.

When the left key of the cross key 9 is operated, the frame number "1" in FIG.
The cursor at “4” is moved to the frame number “13” as shown in FIG. 6C, and the thumbnail image with the frame number 13 is selectable. By operating the enter key in this state, the operations after step 3 are executed.

Next, when the upper key of the cross key 9 is operated in the state shown in FIG. 6A, the image designating section 35 controls the display circuit 33 as shown in FIG. , An index image excluding the thumbnail images displayed before the operation, and an index image of a plurality of thumbnail images photographed before the thumbnail images. For example, as shown in FIG.
When the index image including the nine thumbnail images of is displayed, these thumbnail images are not included,
Index images, including thumbnail images taken before those thumbnail images. That is, in this example,
As shown in FIG. 6D, index images including thumbnail images of frame numbers 1 to 9 are displayed.

Immediately after switching to the new index image, the thumbnail image with the latest shooting order among the displayed thumbnail images, that is, the thumbnail image with the frame number 9 in FIG. 6D can be selected. State. In this way, the user can use the left and right keys of the cross key 9 to access each thumbnail image included in the index image.

When the lower key of the cross key 9 is operated in the state shown in FIG. 6A, the image designating section 35 controls the display circuit 33, as shown in FIG. An index image excluding the thumbnail images displayed before the operation is displayed, and index images of a plurality of thumbnail images photographed after the thumbnail images are displayed. In this example, an index image including nine thumbnail images of frame numbers 19 to 27 is displayed. When the down key is operated, immediately after switching to the new index image, the thumbnail image whose shooting order is the earliest among the displayed thumbnail images, that is, in FIG. , Is in a selectable state.

According to such a configuration, frame advance is realized in units of index images, so that when a large number of images are recorded on the memory card, a desired image can be reached at a very high speed. effective.

The present invention is not limited to the above embodiment, but can be variously modified without changing the gist of the invention.

For example, in this embodiment, an index screen in which nine thumbnail images of 3 × 3 are arranged is used as an example. However, the user operates the input interface 27 to perform, for example, 2 × 2 = 4 frames. A predetermined number of frames such as 4 × 4 = 16 frames can be designated. In this case, the index image judging section 37 shown in FIG. 3 judges the number of frames and controls the display circuit 33 to display on the display section 7 as an index image display including thumbnail images of a predetermined number of frames. Here, the selection of the full image is the same as in the first embodiment, and a description thereof will be omitted.

In the above embodiment, an embodiment in which a full image and a thumbnail image are displayed on the same screen is not particularly described, but the full image and the thumbnail image are displayed together on the same screen. In this case, the present invention is applicable. In this case, the images displayed on the same screen may be one full image and one thumbnail image, or one full image and a plurality of thumbnail images, and can be appropriately modified according to the situation. .

Although the cross key as the frame selection unit has been described as a part of the digital camera, it may have a remote control function and be removable.
