[Configuration example of previewing means]
The camera includes a continuous shooting condition setting unit 111, an imaging unit 112, a condition value increasing / decreasing unit 113, and a combining display unit 114. In a preview mode, a subject image is continuously captured by a single shutter operation while changing shooting conditions. Then, the captured images are compared with the imaging conditions, and one image is displayed for each imaging condition value. Further, continuous shooting can be performed by changing the depth of field, the color, and the like. The previewing means 110 may be constituted by a hardware circuit, but in the present embodiment, it is constituted by a program, and a ROM (or a flash memory 5) is used.
1). Each of the above means (module)
May be configured by a hardware circuit, and the other may be configured by a program.

When the preview mode is selected, the continuous shooting condition setting means 111 displays a shooting condition, an initial shooting condition value and an increase / decrease value thereof on the selection screen to urge the user to make a selection. The photographing condition value A0 and the number of continuous shots (or increase / decrease value) are temporarily stored in the RAM of the control unit 20, and the width D of the value of the photographing condition and the number of continuous shots C
From the above, the increase / decrease value B = D / C is obtained and stored in the RAM. In this case, the initial shooting condition value may be automatically selected (however, the number of continuous shootings is selected by the user).

Note that a preview (continuous shooting) is performed under the selected shooting conditions.
With respect to the image selected by the user from the images obtained, the photographing conditions of the image can be fixed, and further another photographing condition can be selected. Further, for an image selected by the user from images previewed (continuously shot) under the selected shooting condition, the same shooting condition can be further selected using the shooting condition of the image as an initial condition. The increase / decrease value in this case is a value obtained by dividing the previous photographing increase / decrease value by the newly selected number of continuous shootings. For example, assuming that the aperture value of the selected image = 6, the previous increase / decrease value = 2, the current number of continuous shots = 4, the current increase / decrease value =
0.5, and aperture value = 2, 2.5, 3,
The 3.5 image is continuously shot.

When the shutter button 38 is operated, the imaging means 112 transmits the photographing condition value Ai-1 (i = 1,..., N) temporarily stored in the RAM to the optical system 11 or the signal converter 12. And sequentially stores the captured image in one of the image buffers 61-1 to 61-n of the DRAM, and stores the address (or number 1 to n) of the image buffer and the photographing condition value in the RAM. And temporarily store them.

The condition value increasing / decreasing means 113 counts the number of continuous shootings, and when the count value does not exceed the set number of continuous shootings C, increases or decreases the previous shooting condition value Ai temporarily stored in the RAM by the increase / decrease value B. , The current photographing condition value Ai + 1 is calculated and temporarily stored in the RAM, and the process proceeds to the image pickup means 112.
When the count value exceeds the set number of continuous shootings C, the process proceeds to the combining display unit 114.

The composite display means 114 sequentially displays the images stored in the image buffer of the DRAM 14 on the display unit 40. In this case, the photographing condition code and the photographing condition value corresponding to the displayed image are extracted from the RAM, converted into characters, and superimposed on the displayed image.

[Display Example] In FIG. 5, (a) shows an object viewed through the finder, (b) shows a selection screen, and (c) shows an example of an image obtained by continuously photographing by changing the aperture value. In the example, continuous shooting is performed in the preview mode using the shutter speed as a shooting condition, an image with a shutter speed of 1/800 is selected, and “aperture” is selected as the next shooting condition, and the number of continuous shots is set to four. It is a display example of a case. In (c), the shooting conditions and the increased / decreased condition values 71-1,..., 71-4 are superimposed and displayed for each of the images 70-1,. The user can scroll the continuous image vertically or horizontally by operating a scroll button (not shown).

[Operation Example] Hereinafter, the user operates a function button to select a preview mode (S0), and steps S1 to S1 are performed.
11 shows an operation example in which continuous shooting is performed in the preview mode with the shutter speed as a shooting condition, an image with a shutter speed of 1/800 is selected, and further the next shooting condition is selected.

After the transition from S11, the continuous shooting condition setting means 111 is activated again and the shooting condition code "01" of the shutter speed stored in the RAM and the shooting speed stored in the RAM other than the shutter speed value 1/800 are stored. The condition value and the image buffer address (or buffer number) are deleted, and the photographing condition, the initial photographing condition value, and the increase / decrease value thereof are displayed on the selection screen (FIG. 5B) to prompt the user to make a selection (S1).

When the user selects “aperture” as the shooting condition and “4” as the number of continuous shootings, the shooting condition code “02”
Number of continuous shots = 2 and shooting condition value A0 = 4 (initial aperture value)
Is temporarily stored in the RAM. Also, the photographing condition value A0 = 4
(Initial aperture value) and aperture width = 11-3 = 8, increase / decrease value = 8
/ 4 = 2 is calculated and temporarily stored in the RAM (S2).

When the shutter button 38 is operated (S
3) The shutter speed 1/800 and the aperture value 4 temporarily stored in the RAM are compared with the optical system 11 or the signal converter 1.
2 (S4), one image is captured (S5), the captured image is temporarily stored in the image buffer 61-1 of the DRAM, and the address of the image buffer (or buffer number = 1) is stored in the RAM. And the aperture value = 4 are temporarily stored in association with each other (S6).

The condition increasing / decreasing means 113 counts the number of continuous shootings, compares the count value with the selected number of continuous shootings 4, and when the count value exceeds the set number of continuous shootings 4, the combining display means 114 (S7). If the count value does not exceed the set number of continuous shootings 4, the current aperture value Ai + 1 is calculated by adding the increase / decrease value 2 to the previous aperture value temporarily stored in the RAM, and is stored in the RAM. This operation is temporarily stored, and the process returns to the imaging unit 112 to repeat this operation until the count value exceeds the continuous shooting number 4 (S8).

By the above operation, the image buffers 61-1 to 61-1
61-n stores image data captured with aperture values of 4, 6, 8, and 10, and the RAM stores a shooting condition code “0”.
In addition to "1", shutter speed 1/800, shooting condition code "02" and aperture values 4, 6, 8, and 10 are temporarily stored.

In step S7, when the count value exceeds the set number of continuous shootings 4, the images stored in the image buffer 61-1 are sequentially displayed on the display unit 40. In this case, R
The shooting condition code and the aperture value (shooting condition value) corresponding to the displayed image are extracted from the AM, converted into characters, and superimposed on the displayed image (FIG. 5C) (S
9).

When the user operates a scroll button (not shown) to display the next image, the process returns to S9 to superimpose the images in the image buffers 61-2 to 61-4 and the corresponding aperture values. Display sequentially. In this case, the reverse direction (61
-1 → 61-4 → 61-3 → 61-2) can also be displayed (S10).

In step S10, if there is no scroll image display operation, it is determined whether the function selection button 35 has been pressed.
If the button is pressed, the process returns to S1 assuming that the next shooting condition has been designated (S11).

If the function selection button 35 is not pressed in S11, it is checked whether the recording button (not shown) has been pressed. If the function button 35 has been pressed, the process goes to the recording means 120 and the image currently displayed is displayed. (For example, an image with an aperture value of 6) is recorded in the flash memory 51, and if the record button is not pressed, the preview mode processing ends (S12, S1).

This is a display example in which continuous shooting is performed in the preview mode, an image with a shutter speed of 1/800 is selected, and “aperture” is selected as the next shooting condition, and the number of continuous shooting is set to 4. In (b), the photographing condition and the condition value after increase / decrease are superimposed and displayed for each of the images 81-1,..., 81-4.
If the number of continuous shots is 5 or more and four or more reduced images cannot be displayed on the screen, the user can scroll the reduced images vertically or horizontally by one frame by operating the scroll buttons.

[Operation Example] Hereinafter, the user operates the function buttons to select the preview mode (T0), and steps T1 to T
An operation example in which continuous shooting is performed in the preview mode using the shutter speed as a shooting condition at 14, an image with a shutter speed of 1/800 is selected, and further the next shooting condition is selected is shown.

After the transition from T14, the continuous shooting condition setting means 111 is activated again and the shooting condition code "01" of the shutter speed stored in the RAM and the shooting speed stored in the RAM other than the shutter speed value 1/800 are stored. The condition value and the image buffer address (or buffer number) are deleted, and the photographing condition, the initial photographing condition value, and the increase / decrease value thereof are displayed on the selection screen (FIG. 5B) to prompt the user to make a selection (T1).

When the user selects “aperture” as the shooting condition and “4” as the number of continuous shootings, the shooting condition code “02”
Number of continuous shots = 2 and shooting condition value A0 = 4 (initial aperture value)
Is temporarily stored in the RAM. Also, the photographing condition value A0 = 4
(Initial aperture value) and aperture width = 11-3 = 8, increase / decrease value = 8
/ 4 = 2 is calculated and temporarily stored in the RAM (T2).

When the shutter button 38 is operated (T

(T7). If the count value does not exceed the set number of continuous shootings 4, the current photographing condition value Ai + 1 is calculated by adding the increase / decrease value = 2 to the previous aperture value temporarily stored in the RAM. Temporarily stored in a RAM,
The operation is repeated until the count value exceeds 2 and the count value exceeds 4 (T8).

By the above operation, the image buffers 61-1 to 61-1

In addition to "1", shutter speed 1/800, shooting condition code "02" and aperture values 4, 6, 8, and 10 are temporarily stored.

At T7, if the count value exceeds the set number of continuous shootings 4, the image buffers 61-1 to 61-
4 is sequentially reduced (T9), and the reduced image data is sequentially stored in the reduced image buffers 62-1 to 62-4 (T10).

If the number of repetitions of T9 and T10 exceeds the number of continuous shootings 4, the reduced image buffers 62-1 to 62-4
Is extracted and displayed on the screen of the display unit 40 in a two-dimensional array. In this case, the photographing condition code and the aperture value corresponding to the displayed image are taken out from the RAM, converted into characters, and superimposed on the displayed reduced image (T12).
