The display size of the continuous shot image data for the number exceeding the predetermined number 100 is adjusted so as to display a list on the display screen.
In the case of adjusting the display sizes of the third and fourth continuous shot image data, if the number of the plurality of continuous shot images is larger than a predetermined number, for example, 100, the image size adjusting unit 33-2 displays the liquid crystal display. The display size of each image data of the continuous shot image data is adjusted to a display size equal to each length obtained by dividing the lengths of 11 display screens in the vertical and horizontal directions by a predetermined integer.

Fifth, the image size adjustment unit 33-2 displays a plurality of continuous shot image data in a list on the display screen of the liquid crystal display 11 in the unfolded display mode, respectively, in the vertical and horizontal directions on the display screen of the liquid crystal display 11. A first display is performed in which a plurality of continuous-shot image data is arranged and displayed by quantity. In other words, the image size adjustment unit 33-2 arranges (N × N) a plurality of continuous shot image data of N pieces in the vertical direction and N pieces in the horizontal direction on the display screen of the liquid crystal display 11. indicate. In this case, N is an arbitrary integer. Thereby, on the display screen of the liquid crystal display 11, a plurality of continuous shot image data such as N × N = 3 × 3, 4 × 4 and the like are arranged and displayed in the vertical and horizontal directions.
Further, the image size adjustment unit 33-2, when displaying a plurality of continuous shot image data as a list on the display screen of the liquid crystal display 11 in the expanded display mode, is predetermined in the vertical direction on the display screen of the liquid crystal display 11. A second display is performed in which a plurality of continuous image data of a certain quantity are arranged and a plurality of continuous image data of a quantity smaller than a predetermined quantity are arranged and displayed in the horizontal direction. In other words, the image size adjustment unit 33-2 has a plurality of M pieces of continuous shot image data in which the number N in the vertical direction on the display screen of the liquid crystal display 11 is smaller than the number N in the vertical direction by an arbitrary number K in the horizontal direction. Are arranged (N × M) and displayed. In this case, K and M are arbitrary integers, and K is smaller than N and M. Thereby, on the display screen of the liquid crystal display 11, a plurality of continuous shot image data such as N × M = 3 × 2, 4 × 2, and 5 × 3 are arranged and displayed in the vertical and horizontal directions.
Further, the image size adjusting unit 33-2 displays a plurality of continuous shot image data in a list on the display screen of the liquid crystal display 11 in a development display mode, and displays a predetermined quantity in the vertical direction on the display screen of the liquid crystal display 11. A third display is performed in which a plurality of continuous shot image data is arranged and a plurality of continuous shot image data of a quantity smaller than a predetermined quantity is arranged and displayed in the horizontal direction.

That is, the image size adjustment unit 33-2 arranges a plurality of continuous shot image data of M pieces which are smaller by an arbitrary quantity K than N pieces in the vertical direction on the display screen of the liquid crystal display 11 and N pieces in the horizontal direction (M × N) and display. Thereby, on the display screen of the liquid crystal display 11, a plurality of continuous image data such as M × N = 2 × 3, 4 × 5, and 5 × 7 are arranged and displayed in the vertical and horizontal directions.

  The apparatus includes a battery 42 and a power supply circuit 43. The battery 42 can be charged and discharged, for example. The power supply circuit 43 supplies power from the battery 42 to each section in the apparatus, that is, the image pickup device 31, the image pickup circuit 32, the CPU 33, the AE circuit 35, the AF circuit 36, the image processing circuit 37, the removable memory 38, and the display drive circuit. 40, the built-in memory 41, and the liquid crystal display 11.

Next, the operation of the apparatus configured as described above will be described.
First, according to the camera basic operation flowchart shown in FIG. 3, when the power SW 22 is operated and the power is turned on, after the various settings in step S1, in step S2, the power SW 22 is operated again and turned off. Judge whether or not. As a result of this determination, when the power SW 22 is operated again, the power is turned off.

If the power SW 22 is not operated again, the CPU 33 determines in step S3 whether or not the camera mode of the shooting mode or the playback mode is selected by operating the mode dial 12, for example. As a result of this determination, if the shooting mode is selected, the CPU 33 moves to step S4, sets the shooting mode, and takes a series of continuous shootings, for example, shooting a single frame for each frame or continuous shooting. And so on. Thereafter, in step S5, the CPU 33 determines whether or not to end the shooting mode.
On the other hand, if the camera mode is selected as a result of the determination of the camera mode, the CPU 33 moves to step S6, sets the playback mode, and executes a playback mode flowchart shown in FIG. Thereafter, in step S7, the CPU 33 determines whether or not to end the reproduction mode.

Next, the operation in the reproduction mode will be described with reference to the reproduction mode flowchart shown in FIG.
When the reproduction mode is set, the CPU 33 designates the latest image in step S10, and displays the designated image data on the liquid crystal display 11 in one frame in the next step S11. For example, if the latest image is one image D ₉ acquired by normal single shooting as shown in FIG. 18, the CPU 33 reads the image D ₉ from, for example, the removable memory 38 and passes it through the display drive circuit 40. One frame is displayed on the display screen of the liquid crystal display 11. Further, if the continuous image D ₅ latest images are acquired by continuous shooting, as shown in FIG. 19, CPU 33 is one representative image, for example, removable memory representing the continuous image D ₅ 38 Is displayed on the display screen of the liquid crystal display 11 through the display drive circuit 40.

Next, in step S12, the CPU 33 determines whether or not to end the reproduction mode. If it is not the end of the reproduction mode, the CPU 33 proceeds to step S13 and determines whether or not the designated latest image is a continuous shot image. The result of this determination, if it is determined that the latest image is, for example, continuous image D ₅ is continuous image is selected, CPU 33 moves to step S14, the display mode folding display mode continuous image D ₅ or It is determined whether the display mode is expanded.
Here, the continuous shooting index displaying the display image D _5-1 to D _5-7 of the display is, for example, deployed in example 7 Like the continuous shooting image D ₅ as shown in FIG. 20 on the screen of the liquid crystal display 11 If it is a display, the CPU 33 proceeds to step S15 and determines whether or not an instruction for the folding display mode is received by operating the wide / tele button 1 or the mode dial 12, for example. As a result of the determination, when an instruction for the folding display mode is received, the process proceeds to step S16, and the continuous shooting folding display of one frame as shown in FIG. 20 is performed. If the instruction for the folding display mode is not received, the CPU 33 proceeds to step S19.

On the other hand, if the display on the display screen of the liquid crystal display 11 is, for example, one frame continuous folding display as shown in FIG. 20, the CPU 33 moves from step S14 to step S17, for example, the wide / tele button 1 or It is determined whether or not an instruction for the expanded display mode has been received by operating the mode dial 12. The result of this determination, when receiving an instruction to expand the display mode, proceeds to step S18, for example, an image _D 5-1 _{to D 5-7} expand continuous shooting image _{D 5} example of seven as shown in FIG. 20 The displayed continuous shooting index is displayed.

  If the result of determination in step S13 is not a continuous-shot image, the CPU 33 moves to step S19 and determines whether or not an instruction for frame advance or frame return for each frame has been received. For example, when receiving an instruction for frame advance or frame return for each frame, the CPU 33 moves to step S20 and performs frame advance or frame return for each frame.

Next, the frame advance or frame return operation for each frame will be described with reference to the one frame advance / return flowchart shown in FIG.
In step S30, the CPU 33 determines whether, for example, the right button 20 has been operated. If the right button 20 is operated as a result of this determination, the CPU 33 moves to step S31 and designates the next one frame image data arranged on the right side. For example, when the right button 20 in a state in which the representative image data of one representative of continuous shots image D ₅ as shown in FIG. 20 is 1 frame display is operated, CPU 33 is of continuous images D ₅ One piece of representative image data representing the continuous shot image D ₆ arranged on the right side is displayed on the display screen of the liquid crystal display 11 as one frame.

Next, in step S32, the CPU 33 determines whether, for example, the left button 19 has been operated. If the left button 19 is operated as a result of this determination, the CPU 33 moves to step S33 and designates the previous frame image data arranged on the left side. For example, a state in which one representative image data representing the continuous shooting image D ₅ as shown in FIG. 20 is displayed in full-frame when the left button 19 is operated, CPU 33 is of continuous images D ₅ The image D ₄ arranged on the left side is displayed as a single frame on the display screen of the liquid crystal display 11.

Next, in step S34, the CPU 33 determines whether, for example, the upper button 17 has been operated. If the upper button 17 is operated as a result of this determination, the CPU 33 proceeds to step S35 and designates the image data of the first frame arranged on the upper side. For example, when the upper button 17 in the state in which the representative image data of one representative of continuous shots image D ₅ as shown in FIG. 20 is 1 frame display is operated, CPU 33 is of continuous images D ₅ an image D ₂ which is arranged on the upper side to one frame displayed on the display screen of the liquid crystal display 11.

Next, in step S34, the CPU 33 determines whether, for example, the down button 18 has been operated. As a result of this determination, when the lower button 18 is operated, the CPU 33 proceeds to step S36 and designates the image data of one frame at the rear end arranged on the lower side. For example, when the down button 18 in a state in which the representative image data of one representative of continuous shots image D ₅ as shown in FIG. 20 is 1 frame display is operated, CPU 33 is of continuous images D ₅ The image D ₈ arranged on the lower side is displayed on the display screen of the liquid crystal display 11 as one frame.

Next, the continuous shooting index display when receiving the instruction of the expansion display mode (step S18) will be described with reference to the first continuous shooting expansion display flowchart shown in FIG.
In step S40, the image size adjustment unit 33-2 compares the predetermined number of continuous shots for determination, for example, 5 with the number of continuous shot images. The number of continuous shot images is obtained, for example, by counting a plurality of continuous shot image data stored in the removable memory 38 or the built-in memory 41.

  As a result of the comparison between the number of continuous shots for determination and the number of continuous shots, if the number of continuous shots is 5 or less, the image size adjustment unit 33-2 The number of divisions on the display screen is determined to be “4”, and each piece of image data of a plurality of continuous shot image data is displayed in four divisions on the display screen of the liquid crystal display 11 with an image size corresponding to the division number “4”. In this case, the image size adjustment unit 33-2 displays all of the plurality of continuous shot image data simultaneously on the display screen of the liquid crystal display 11.

For example, when the continuous image data D ₃ having _three continuous images is selected and the development button 5 is operated in a state where the normal index display is performed as shown in FIG. 9, for example, the image size adjustment unit In 33-2, since the number of continuous shot images ₃ included in the continuous shot image data D3 is 5 or less, the process proceeds to step S41, and the number of divisions on the display screen of the liquid crystal display 11 is set to “3”. 4 ”, and three continuous shot images D _{3-1 to} D _3-3 are displayed on the display screen of the liquid crystal display 11 with an image size corresponding to the division number“ 4 ”. That is, if the number of continuous shot images is 5 or less for determination, the number of divisions on the display screen of the liquid crystal display 11 is any number of 1 to 4 continuous shot images. Is determined to be “4”. Accordingly, if the number of continuous shot images is any one of 1 to 4, the image size of the continuous shot image data is an image size corresponding to the division number “4”.

Next, if the number of continuous shot images is 5 or more, the image size adjustment unit 33-2 moves to step S42, and sets a predetermined number of continuous shots for determination, for example, 10 and the number of continuous shot images. Compare For example, a state that the ordinary index displayed as shown in FIG. 10, when the expand button 5 continuously shot image data D ₅ is selected having, for example, seven continuous images of the operation, the image size adjustment unit 33-2, since the number seven continuous image including the continuously shot image data D ₅ is not more than 10 sheets for continuous shooting count determination, the routine goes to step S43, the number of divisions of the display screen of the liquid crystal display 11 " 9 ”, and seven continuous shot images D _{5-1 to} D _5-7 are displayed on the display screen of the liquid crystal display 11 with an image size corresponding to the division number“ 9 ”. That is, similarly to the above, if the number of continuous shot images is 10 or less for determination, the display screen of the liquid crystal display 11 can be used regardless of the number of continuous shot images from 5 to 10. The upper division number is determined to be “9”. Thus, if the number of continuous shot images is any number from 5 to 10, the image size of the continuous shot image data is an image size corresponding to the division number “10”.

Next, if the number of continuous shot images is 10 or more, the image size adjustment unit 33-2 proceeds to step S44, and sets a predetermined number of continuous shots for determination, for example, 17 and the number of continuous shot images. Compare For example, a state that the ordinary index display as shown in FIG. 11, when the expand button 5 continuously shot image data D ₆ is selected to have a 16 sheets continuous images of example is operated, the image size adjustment unit 33-2, since the 16 sheets the number of continuously shot image including the continuous image D ₆ is below continuous number 17 sheets for determination, the routine goes to step S45, "16 division number on the display screen of the LCD 11 , And sixteen continuous shot images D _{6-1 to} D _6-16 are displayed on the display screen of the liquid crystal display 11 with an image size corresponding to the division number “16”.

Similarly, for example, if the number of continuous shot images is 91 or more, the image size adjustment unit 33-2 compares the predetermined number of continuous shots for determination, for example, 100 with the number of continuous shot images. To do. For example, a state that the ordinary index displayed as shown in FIG. 12, when the expand button 5 continuous image D ₈ is selected with 95 sheets continuous images of example is operated, the image size adjustment unit 33 -2, since 95 Like the number of continuously shot image including the continuous image D ₈ is below 100-sheet continuous count determination, the flow proceeds to step S46, the number of divisions of the display screen of the liquid crystal display 11 "100" determined, the continuous shooting display index on the display screen of the division number "100" of 95 sheets of image size in accordance with the continuous image _D 8-1 _{to D 8-95} LCD 11 a.
In the first continuous shooting expansion display, a predetermined number of continuous shots for determination, for example, 5, 10, 17, etc., is set. However, the present invention is not limited to this, and the setting can be arbitrarily changed. is there.

Next, another method for determining the number of divisions on the display screen of the liquid crystal display 11 by the image size adjusting unit 33-2 will be described with reference to a second continuous shooting expansion display flowchart shown in FIG.
First, the image size adjustment unit 33-2 in step S50, obtains the number _{N 1} of the continuous image.
Then, the image size adjusting section 33-2, in step S51, calculates the square root of _{N 2} number _{N 1} of a plurality of continuously shot image as shown in the equation (1).
Then, the image size adjusting section 33-2, in step S52, obtains the value N obtained by rounding up the first place of the square root of the value _{N 2} decimals.

Then, the image size adjusting section 33-2, in step S53, the number of divisions vertical and horizontal directions on the display screen of the liquid crystal display 11 the value N obtained by rounding up the first place of the square root of the value N ₂ decimal N × N And the display screen of the liquid crystal display 11 is divided and displayed in N × N.
For example, when the number N ₁ of continuous shot images is “5”, the value N ₂ of the square root of N ₁ = “5” is about “2.2”. When the first decimal place of the square root value N ₂ (= 2.2) is rounded up, the value N becomes “3”. Therefore, the display screen of the liquid crystal display 11 is divided and displayed in N × N (= 3 × 3).

Next, divided display on the display screen of the liquid crystal display 11 by the image size adjustment unit 33-2 will be described with reference to a third continuous shooting expansion display flowchart shown in FIG.
For example, a state that the ordinary index displayed as shown in FIG. 13, for example, four expansion button 5 continuous image D ₃ is selected to have a continuous shooting image is operated, the image size adjustment unit 33 -2 compares the predetermined number of continuous shots for determination, for example, seven in step S60 with the number of continuous shot images of four. As a result of the comparison, since the number of continuous shot images is 4 or less, the image size adjustment unit 33-2 moves to step S61 and sets the division number on the display screen of the liquid crystal display 11 to “6”. The four continuous shot images D _{3-1 to} D _3-4 are displayed on the display screen of the liquid crystal display 11 with the image size corresponding to the division number “6”. That is, if the number of continuous shot images is 7 or less, the number of divisions on the display screen of the liquid crystal display 11 regardless of the number of continuous shot images from 1 to 6. Is determined to be “6”. As a result, if the number of continuous shot images is any one of 1 to 6, the image size of the continuous shot image data is an image size corresponding to the division number “6”.

Next, if the number of continuous shot images is 7 or more, the image size adjusting unit 33-2 moves to step S62, and sets a predetermined number of continuous shots for determination, for example, 13 and the number of continuous shot images. Compare For example, a state that the ordinary index displayed as shown in FIG. 14, when the expand button 5 continuous image D ₅ is selected having, for example, seven continuous images of the operation, the image size adjustment unit 33 -2, since the number seven continuous image including the continuous image D ₅ is not more than continuous number 13 sheets for determination, the flow proceeds to step S63, the number of divisions of the display screen of the liquid crystal display 11 "12" And seven continuous shot images D _{5-1 to} D _5-7 are displayed on the display screen of the liquid crystal display 11 with an image size corresponding to the division number “12”. That is, as described above, if the number of continuous shot images is 13 or less for determination, the display screen of the liquid crystal display 11 can be used regardless of the number of continuous shot images from 7 to 12. The upper division number is determined to be “12”. As a result, if the number of continuous shot images is any of 7 to 12, the image size of the continuous shot image data is an image size corresponding to the division number “12”.

Next, if the number of continuous shot images is 13 or more, the image size adjustment unit 33-2 proceeds to step S64, and sets a predetermined number of continuous shots for determination, for example, 21 and the number of continuous shot images. Compare For example, when the continuous image D ₆ having 16 continuous images is selected and the development button 5 is operated while the normal index is displayed as shown in FIG. No.-2, since the number of continuous-shot images 16 included in the continuous-shot image D ₆ is 21 or less for continuous-shot images for determination, the process proceeds to step S65, and the division number on the display screen of the liquid crystal display 11 is set to “20”. The 16 continuous shot images D _{6-1 to} D _6-16 are displayed on the display screen of the liquid crystal display 11 with the image size corresponding to the division number “20”.

Similarly, for example, if the number of continuously shot images is 28, the image size adjustment unit 33-2 determines the number of divisions on the display screen of the liquid crystal display 11 to be “30”. 28 sheets of continuous image _D 8-1 _{to D 8-28} in image size for continuous shooting index display on the display screen of the liquid crystal display 11 in accordance with the ".
For example, if the number of continuously shot images is 91 or more, the image size adjusting unit 33-2 compares a predetermined number of continuous shots for determination, for example, 100 with the number of continuously shot images. If as a result of this comparison example continuous image D ₈ continuous shooting number is continuous sheets 100 sheets or less for the determination of the image including the image size adjustment unit 33-2, the division number on the display screen of the LCD 11 _Is determined to be “100”, and 95 continuous shot images D _{8-1 to} D _8-95 are displayed on the display screen of the liquid crystal display 11 with an image size corresponding to the division number “100”.
Note that in the third continuous shooting expansion display, a preset number of continuous shots for determination, for example, seven, thirteen, twenty-one, etc., is set, but the present invention is not limited to this, and the setting can be changed arbitrarily. is there.

In this case, the image size adjustment unit 33-2, for example, 100 sheets of the continuous image _D 9-1 _{~D 9-100} as shown in Figure 17 continuous shooting display index on the first page, it exceeds 100 sheets The continuous shooting image data for the number of sheets, for example, seven continuous shooting images D _{9-100 to} D _9-107 are displayed on the second page as a continuous shooting index. In this case, the image size adjustment unit 33-2 simultaneously displays the continuous shooting image data for the number of sheets exceeding 100 on the second page at the same time. Further, the image size adjusting unit 33-2 sets the display size of the continuous image data for the number exceeding 100 to any one of the first to third continuous shooting expansion display flowcharts shown in FIGS. This is determined according to one continuous shooting development display flowchart.

  Further, if the number of the plurality of continuous shot image data is larger than a predetermined number, for example, 100, the image size adjusting unit 33-2 sets each length in the vertical and horizontal directions of the display screen of the liquid crystal display 11 to a predetermined integer. You may adjust the display size of each image data of continuous-shot image data to the display size equal to each divided length.

Further, the image size adjusting unit 33-2 displays a plurality of continuous shot image data in the vertical and horizontal directions on the display screen of the liquid crystal display 11 when a plurality of continuous shot image data is displayed as a list on the display screen of the liquid crystal display 11 in the expanded display mode. The number of sheets may be set as follows.
For example, the image size adjustment unit 33-2 sets a plurality of continuous shot image data in a list in a vertical and horizontal direction on the display screen of the liquid crystal display 11 when displaying a plurality of continuous shot image data in a list on the display screen of the liquid crystal display 11.
