BACKGROUND OF THE INVENTION
The present invention relates to an image reproducing apparatus having a multi-screen display function for displaying a plurality of still images side by side on the same screen. and Image recording device to which this device is applied In place Related.
[0002]
[Prior art]
In recent years, a subject image is imaged on a solid-state image sensor such as a CCD two-dimensional image sensor by an imaging optical system and converted into an electrical signal, and image data of a still image obtained thereby is converted into a semiconductor memory or a magnetic disk. A so-called electronic camera for recording on a recording medium is becoming widespread. Since this electronic camera is equipped with a display device such as an LCD and can view an image immediately after shooting, it is very convenient to use.
[0003]
In addition to the increase in the capacity of the memory used as a recording medium and the improvement in image processing speed, not only still image shooting, but also continuous shot images consisting of a plurality of still images that are substantially continuous in time are used as moving images. Electronic cameras having a so-called continuous shooting function for taking pictures have also been developed. Recently, many of them have a multi-screen display function that displays a plurality of still images side-by-side on a display device. Therefore, this multi-screen display function is used for still images in continuous shots taken with the continuous shooting function. Display, it is possible to represent the flow of movement of the subject image on the same screen, and it can be used for, for example, a form check during a golf swing.
[0004]
[Problems to be solved by the invention]
By the way, in the conventional electronic camera, when displaying a still image in a continuous shot image captured by the continuous shooting function using this multi-screen display function, a predetermined range from the first still image to the last still image is predetermined. Since the images are displayed at intervals, there is a problem that the multi-screen display desired by the user cannot always be obtained. This problem will be specifically described with reference to FIGS.
[0005]
For example, as shown in FIG. 10, it is assumed that continuous shot images at the time of golf swing are taken for 15 seconds. It is assumed that the swing starts at this time after 10 seconds have passed since the start of imaging (swing time is 3 seconds). In this case, assuming that the electronic camera captures 30 still images per second, 300 still images having substantially the same address posture are captured.
[0006]
Here, it is assumed that 15 still images in this continuously shot image are displayed in 3 × 3 (3 rows and 3 columns) sections, that is, displayed on a multi-screen at intervals of 0.5 seconds. Then, as shown in FIG. 11, in the first multi-screen display, still images having substantially the same address posture are displayed in all the sections. Therefore, the user switches the multi-screen display until the desired still image appears, and after the desired still image appears, the user switches the multi-screen display until all the desired still images have been viewed. It will be.
[0007]
That is, for example, it is very difficult to obtain a multi-screen display in which a subject image with an address posture is arranged in the first section and a subject image with a finish posture is arranged in the last section. It was impossible to obtain a multi-screen display in which the interval from the intermediate zone to the arbitrarily selected intermediate zone and the interval from the middle zone to the final zone were different.
[0008]
The present invention has been made in consideration of such circumstances, and an image reproducing apparatus that can easily obtain a multi-screen display composed of still images extracted from a specific portion in a continuous shot image. and Image recording device to which this device is applied Place The purpose is to provide.
[0009]
[Means for Solving the Problems]
In order to achieve the above-described object, the present invention provides an image reproducing apparatus having a multi-screen display function for displaying a still image different from other sections in each of a plurality of sections created by dividing a display area. A plurality of still images extracted from continuous shot images composed of a plurality of continuous still images are displayed in the section. When the still image to be displayed in the first section of the multi-screen is switched to any continuous image other than the first image in the continuous image, the switched still image is The still images extracted from the continuous shot images so that the interval from the still image after switching to the remaining sections other than the final section to the final still image is approximately equal in time. Multi-screen display control means for displaying It is characterized by comprising.
[0010]
More specifically, when a still image to be displayed in the first section is selected, the still image displayed in the last section from the still image in the selected first section is arranged at approximately equal intervals in time. When a still image to be displayed in each section is extracted, and when a still image to be displayed in the last section is selected, the time period from the still image displayed in the first section to the still image in the selected last section is temporally determined. Still images to be displayed in the respective sections are extracted so as to have substantially equal intervals.
[0011]
In the present invention, since it is possible to easily obtain a multi-screen display composed of still images extracted at a substantially equal interval in time from a specific portion in a continuous shot image, for example, in a continuous shot image obtained by shooting a golf swing When performing multi-screen display for still images, it is possible to easily obtain a multi-screen display in which a subject image with an address posture is placed in the first section and a subject image with a finish posture is placed in the last section. Become.
[0012]
Furthermore, according to the present invention, when a still image displayed in an intermediate section other than the first and last sections is selected, the time from the still image displayed in the first section to the still image in the selected intermediate section is temporally omitted. A still image to be displayed in each section is extracted so that the interval between the still image in the selected intermediate section and the still image being displayed in the last section is approximately equal in time. It is a thing.
[0013]
In the present invention, for example, a multi-screen display can be obtained in which the interval from the first segment to the arbitrarily selected intermediate segment and the interval from the intermediate segment to the final segment can be obtained. For multi-screen display where the subject image in the address posture is placed in the first section and the subject image in the finish posture is placed in the last section, for example, the number of sections from the address posture to the impact posture, conversely, The number of sections from the impact posture to the finish posture can be easily changed.
[0014]

Based on the cumulative addition value, the subject An AE evaluation value corresponding to the brightness of the image is obtained.
[0021]
The AF processing unit 19 receives the digitized pixel signal output from the A / D converter 17 and extracts, for example, a high-frequency component of the pixel signal for one screen by a high-pass filter, and performs cumulative addition or the like on this. An AF evaluation value corresponding to the contour component amount on the high frequency side is calculated by performing arithmetic processing.
[0022]
The image processing unit 20 generates a color image signal of a predetermined format by performing auto white balance, color signal separation, and other processes on the pixel signal.
[0023]
The color image signal generated by the image processing unit 20 is temporarily stored in a buffer memory 21 composed of, for example, a DRAM. The color image signal read from the buffer memory 21 is guided to the display processing unit 22 where it is converted into a form suitable for display output, and then supplied to a color liquid crystal display (LCD) 23 such as a TFT system and displayed as an image. Is done.
[0024]
A compression / decompression processing unit 24 is further connected to the buffer memory 21, and a recording / reproduction processing unit 25 is connected to the compression / decompression processing unit 24. The recording / reproduction processing unit 25 performs processing for recording image data and accompanying data on the recording medium 26 and reproducing image data and accompanying data from the recording medium 26. As the recording medium 26, a memory card composed of a semiconductor memory such as a card type flash memory is generally used. However, the recording medium 26 is not limited to the memory card, and a magnetic recording medium such as a hard disk or a floppy disk. Etc., various forms can be used.
[0025]
The compression / decompression processing unit 24 reads the image signal stored in the buffer memory 21 and performs a compression (encoding) process, thereby forming a compression processing unit suitable for recording on the recording medium 26, An expansion processing unit that reads out image data recorded on the recording medium 26 and performs expansion (decoding) processing. As the compression processing method, for example, the JPEG method is used, but is not limited thereto. The decompressed image signal is temporarily stored in the buffer memory 21 and appropriately displayed on the color liquid crystal display 23 via the display processing unit 22.
[0026]
The external interface unit 27 reads out an image signal stored in the buffer memory 21 and converts it into a form suitable for printing, and then outputs the image signal to an externally connected printer, thereby executing image formation by the printer. Is done.
[0027]
The system controller 28 controls each unit based on the processing results of the AE processing unit 18 and the AF processing unit 19 and a command from the operation unit 30, and is configured using a CPU. Specifically, the system controller 28 includes an image processing unit 20, a buffer memory 21, a display processing unit 22, a compression / decompression processing unit 24, a recording / playback processing unit 25, an external interface unit 27, an AF motor 13 and an aperture motor 14. The motor drivers 41 and 42 to be driven are controlled.
[0028]
That is, the system controller 28 controls the motor driver 52 based on the AE evaluation value obtained by the AE processing unit 18, controls the amount of light by controlling the diaphragm 12 via the diaphragm motor 14, and further controls the CCD. An automatic exposure (AE) process is performed by controlling the charge accumulation time of the CCD 15 via the driver 16. Further, the system controller 31 controls the motor driver 51 based on the AF evaluation value obtained by the AF processing unit 19 and moves the imaging lens 11 in the optical axis direction via the AF motor 13 to perform automatic focus adjustment (AF ) Perform processing.
[0029]
The operation unit 30 generates command signals for performing various operations based on operations by the user of the camera and transmits them to the system controller 28. Specifically, the operation unit 30 is provided with a release switch 31 as a switch for shooting instructions. The release switch 31 is for instructing to capture a still image or a moving image.
[0030]
In addition, the operation unit 30 is instructed with a camera mode switch 32 for instructing an operation mode of the electronic camera such as a photographing mode and a reproduction mode, and a photographing mode of the electronic camera such as a still image mode and a moving image mode. A shooting mode switch 33, a display changeover switch 34 for switching the playback mode of the electronic camera, such as a multi-screen mode or a single frame mode, a confirmation switch 35 for confirming a section selection at the time of multi-screen display, A cross key switch 36 is provided for selecting sections and images when displaying a multi-screen.
[0031]
Referring to FIG. 1, the release switch 31 is a switch that is turned on when the release button 4 is pressed. When the release switch 31 is turned on, recording of an image is instructed by the control of the system controller 28, and the recording medium is recorded. 26, the compressed image data is recorded.

[0037]
In addition to the various types of control described above, the system controller 28 is also a control unique to the present invention, such as multi-screen display control for adjusting a time interval and displaying specific portions in a continuous shot image side by side on one screen. It has the function to perform. Hereinafter, the multi-screen display control will be briefly described.
[0038]
Here, as described above, as shown in FIG. 10, a still image in a continuous shot image at the time of a golf swing photographed for 15 seconds from 10 seconds before the start of the swing to 2 seconds after the completion of the swing is 3 × 3 (3 An example will be described in which a multi-screen display is performed in each section of the three columns.
[0039]
In this multi-screen display control, when an image reproduction is instructed by operating the camera mode button 5 and a multi-screen display is instructed by operating the display switching button 8, first, as an initial state, The first still image is displayed in the first section, the last still image is displayed in the last section, and the remaining sections are displayed at approximately equal intervals from the first still image to the last still image. The still image extracted in such a way is displayed. At the same time, the time interval between adjacent still images on the multi-screen display is also displayed. A display example at this time is shown in FIG. In the example of FIG. 3, it can be seen that the interval between each still image is 1.875 seconds.
[0040]
In the continuous shot image in this example, since the still image has an address posture of 10 seconds from the head in 15 seconds, that is, 2/3 from the head, the address from the head section to the sixth section in the multi-screen display is the address. Occupied by still image of posture. Therefore, in order to switch the still image to be displayed in the first section, the user operates the cross key button 9 to select the first section, operates the confirm button 8 to confirm this selection, and then again presses the cross. The key button 9 is operated to switch the still image to be displayed in the first section. Here, it is assumed that the still image after 10 seconds has been switched. Along with this switching, in this multi-screen display control, the still image after the switching is displayed again in the first section, and the still image after switching to the remaining sections other than the last section is changed to the final still image. The extracted still images are redisplayed so that the time until is approximately equal in time. A display example at this time is shown in FIG. In the example of FIG. 4, it can be seen that the interval between each still image is 0.625 seconds. Note that the grid selection frame a displayed in the upper left section in the multi-screen display shown in FIG. 4 is a guide display for allowing the user to identify the selected section, and the cross key button 9 is pressed. To move between sections.
[0041]
In the continuous shot image in this example, since it is a still image in the finish posture for 2 seconds from the last of 15 seconds, when the still image displayed in the top section is switched to the still image after 10 seconds, 2/5 from the last is obtained. The finishing posture is established, and the final posture in the multi-screen display to the four compartments are occupied by this finishing posture. Therefore, the user next operates the cross key button 9 to select the final section and the confirm button 8 to confirm the selection in order to switch the still image to be displayed in the final section. The cross key button 9 is operated again to switch the still image to be displayed in the last section. Here, it is assumed that the image is switched to a still image after 13 seconds. Along with this switching, in this multi-screen display control, the still image after this switching is displayed again in the last section, and the still image after switching from the first still image to each remaining section other than the first section. The extracted still images are redisplayed so that the time until is approximately equal in time. A display example at this time is shown in FIG. In the example of FIG. 5, it can be seen that the intervals between the still images are 0.375 seconds.
[0042]
As described above, according to this multi-screen display control, a still image with an address posture is displayed in the first section and a still image with a finish position is displayed in the last section. It becomes possible to easily obtain a multi-screen display composed of still images extracted at approximately equal intervals in time from the portion.
[0043]
Next, the user wanted to display the still image (assuming that it is a still image after 12 seconds) displayed in the seventh section more finely than the multi-screen display shown in FIG. The case will be described.
[0044]
In this case, the user operates the cross key button 9 to select, for example, the fourth (middle left) section, operates the confirm button 8 to confirm this selection, and then operates the cross key button 9 again. Then, the still image displayed in the fourth section is switched to the still image after 12 seconds. Along with this switching, in this multi-screen display control, the switched still image is displayed again in the fourth section, and after switching from the first still image to the remaining sections other than the first and last sections. The extracted still images are displayed again so that the still images are substantially equally spaced in time, and the switched still image to the final still image are approximately equally spaced in time. A display example at this time is shown in FIG. In the example of FIG. 6, the interval between the still images in the fourth segment from the first segment is 0.67 seconds, and the interval between the still images in the last segment from the fourth segment is 0.2 seconds. I understand that.
[0045]
Thus, according to this multi-screen display control, for a multi-screen display in which a still image with an address posture is displayed in the first section and a still image with a finish position is displayed in the last section, For example, the number of partitions from the address posture to the impact posture, conversely, the interval from the top partition to the arbitrarily selected intermediate partition, such as easily changing the number of partitions from the impact posture to the finish posture, It becomes possible to easily obtain a multi-screen display in which the interval from the intermediate section to the final section is different.
[0046]
In an electronic camera having a continuous shooting function, the number of pixels of a still image obtained by single shooting is different from the number of pixels of a still image obtained by continuous shooting. Therefore, in this electronic camera, the number of pixels is set as shown in FIG. 7 in consideration of multi-screen display of still images in continuous shot images. That is, the number of pixels (320 × 240) of still images obtained by continuous shooting is set to an integer of the number of pixels (1280 × 960) of still images obtained by single shooting. This makes it possible to simplify recording of images displayed on a multi-screen.
[0047]
Next, the procedure of multi-screen display control in the electronic camera of this embodiment will be described using the flowcharts shown in FIGS. These operations are controlled by the system controller 28.
[0048]
In this electronic camera, first, the operation mode of the electronic camera is set by the camera mode switch 32 (step A1 in FIG. 8). Here, when the shooting mode is set (NO in step A1 in FIG. 8), an image shooting process is executed (step A2 in FIG. 8).
[0049]
On the other hand, when the playback mode is set (YES in step A1 in FIG. 8), the playback mode of the electronic camera is set by the changeover switch 34 (step A3 in FIG. 8). Here, when the single frame mode is set (NO in step A3 in FIG. 8), single frame mode processing for displaying one still image on the LCD 23 is executed (step A4 in FIG. 8). .
[0050]
When the multi-screen mode is set (YES in step A3 in FIG. 8), first, the presence / absence of a display number change instruction by the cross key switch 36 is checked (step A5 in FIG. 8). In the case (YES in step A5 in FIG. 8), designation of the display number is accepted (step A6 in FIG. 8). This display number designation processing is advanced when the user presses the cross key button 8 in response to the guide display on the LCD 23. The initial setting is 3 × 3, for example, 4 × 4, 2 × 2, etc. Select.
[0051]
Next, when a continuous image to be displayed on a multi-screen is selected from all the continuous images recorded on the recording medium 26 by the cross key switch 36 (step A7 in FIG. 8), this selection is made as an initial state. The first still image in the continuous shot image is displayed in the first section, the last still image is displayed in the last section, and the time from the first still image to the last still image is displayed in each remaining section. The extracted still images are displayed so as to be substantially equally spaced (step A8 in FIG. 8).
[0052]
Then, after a multi-screen image editing process to be described later by the confirmation switch 35 and the cross key switch 36 (step A9 in FIG. 8), recording on the recording medium 26 is instructed by the cross key switch 36 (step in FIG. 8). (YES in A10), the image data of the image displayed on the multi-screen is recorded in association with the continuous-shot image on the recording medium 26 on which the continuous-shot image is recorded (step A11 in FIG. 8).
[0053]
When the print output is instructed by the cross key switch 36 (YES in step A12 in FIG. 8), the print data of the image displayed on the multi-screen is directed to the printer connected externally via the external interface unit 27. Output (step A13 in FIG. 8).
[0054]
In the multi-screen image editing process, first, it is checked whether or not there is an instruction to move the grid selection frame a by the cross key switch 36 (step B1 in FIG. 9), and if there is (YES in step B1 in FIG. 9), the cross key switch. The grid selection frame a is moved and fixed according to the operation of 36 and the confirmation switch 35 (step B2 in FIG. 9). Next, it is checked whether or not there is a still image change instruction from the cross key switch 36 (step B3 in FIG. 9), and if there is (YES in step B3 in FIG. 9), it is checked whether or not the grid selection frame a is the first section. (Step B4 in FIG. 9).
[0055]
If the grid selection frame a is the first section (YES in step B4 in FIG. 9), the still image in the grid selection frame a is changed according to the operation of the cross key switch 36 (step B5 in FIG. 9). Still images obtained by extracting still images of all the sections other than the last section so that the still images in the grid selection frame a that is the first section to the still images of the last section are approximately equally spaced in time. The image is changed (step B6 in FIG. 9).
[0056]
If the grid selection frame a is the last section (NO in step B4 in FIG. 9 and YES in step B7 in FIG. 9), the still image in the grid selection frame a is changed according to the operation of the cross key switch 36. (Step B8 in FIG. 9), the images of all the sections other than the head section are temporally abbreviated from the still image of the head section to the still image in the grid selection frame a which is the last section. It changes to the extracted still image so that it may become equal intervals (step B9 of FIG. 9).
[0057]
Further, if the grid selection frame a is an intermediate section other than the first and last (NO in step B4 in FIG. 9 and NO in step B7 in FIG. 9), the grid selection frame a is set in accordance with the operation of the cross key switch 36. 9 (step B10 in FIG. 9), the images of all the sections other than the first section and the last section are displayed in the grid selection frame a that is an intermediate section from the still image of the first section. To the still image extracted in such a manner that the still image in the grid selection frame a which is the middle section is substantially equidistant in time, and the still image in the last section from the still image in the middle section is approximately equidistant. Change (step B11 in FIG. 9).
[0058]
As described above, according to the multi-screen display control of the electronic camera, it is possible to easily obtain a multi-screen display composed of still images extracted at substantially equal intervals in time from a specific portion in the continuous shot image. In addition, it is possible to easily obtain a multi-screen display in which the interval from the first division to the arbitrarily selected intermediate division and the interval from the intermediate division to the final division are different.
[0059]
In this embodiment, an example in which the multi-screen display control of the present invention is applied to an electronic camera has been described. However, the present invention is not limited to this. For example, an image recording apparatus or a recording medium for recording an image on a recording medium It is also possible to apply to an image forming apparatus for forming an image recorded on the paper on a sheet, which is useful.
[0060]
【The invention's effect】
As described above in detail, according to the present invention, when a still image to be displayed in the first section is selected, the time period from the selected still image in the first section to the still image displayed in the last section is temporally changed. When still images to be displayed in each section are extracted so as to be approximately equally spaced, and when a still image to be displayed in the last section is selected, the selected last section is selected from the still images displayed in the first section. Since still images to be displayed in each section are extracted so that the time until the still images are approximately equal to each other in time, for example, when performing a multi-screen display for still images in a continuous image obtained by shooting a golf swing In addition, a subject image with an address posture is placed in the first section, and a subject image with a finish posture is placed in the last section, and is extracted at approximately equal intervals in time from a specific portion in the continuous shot image. It becomes possible to a obtain easily multi-screen display comprising a static image.
[0061]
Furthermore, when a still image displayed in an intermediate section other than the first and last sections is selected, the still image currently displayed in the first section and the still image in the selected intermediate section are approximately equally spaced in time. And, since the still image displayed in each section is extracted so that the still image being displayed in the final section from the still image of the selected intermediate section is approximately equally spaced in time, For example, when performing a melch screen display on a still image in a continuous image obtained by shooting a golf swing, a subject image in an address posture is disposed in the first section, a subject image in a finish posture is disposed in the last section, The number of partitions from the address posture to the impact posture, or conversely, from the top partition that easily changed the number of partitions from the impact posture to the finish posture. And distance to the middle section of the chosen, it is possible to obtain a multi-screen display having different and spacing to the final section of the compartment of the intermediate easier.
