Description

  The present invention relates to an image recording apparatus, and more particularly, to an image recording apparatus that can eliminate a failed photograph when it is photographed in an automatic photographing mode.

  In recent years, many digital still cameras (hereinafter referred to as digital cameras) and silver salt film cameras have various automatic photographing functions (automatic photographing modes). The automatic shooting mode includes, for example, an interval shooting mode in which shooting is repeated at a preset time interval, a timer shooting mode in which shooting is performed at a preset time, and shooting after a preset time has elapsed since the operation of the operation switch. There are known a self-timer shooting mode in which shooting is performed, a remote control shooting mode in which shooting is performed by remote control, and the like.

The following technologies are related to the automatic shooting mode.
<Prior Art 1> (Auto Bracketing)
This technology automatically changes the exposure in one release operation (pressing the shutter button) and automatically takes multiple pictures. For example, the exposure is set so that the combination of the aperture and the shutter speed is changed so that the exposure is −0.5 EV for proper exposure and +0.5 EV for proper exposure. When a flash is used, it can be changed including the flash emission amount.

<Conventional technology 2>
This is a technique for shooting a predetermined number of images by switching the amount of flash emission for each image in one release operation (for example, Patent Document 1).
<Prior Art 3>
This is a technique that includes a storage medium that records a selected image from a plurality of images that are shot by changing the shooting conditions in one release operation (for example, Patent Document 2). ).

Further, the followings are known as prior art relating to strobes.
The amount of light necessary to obtain proper exposure with strobe light is represented by a numerical value given by the following equation called a guide number (GNo.).
GNo. = F × L
Here, F: F value of the photographic lens, L: distance to the subject, where ISO sensitivity of the film or ISO equivalent sensitivity of the image sensor is 100.

<Conventional technology 4> (Auto strobe system)
When the light emitted from the strobe and reflected by the subject is measured with a photometric sensor provided on the camera body or a strobe device that can be attached to the camera, and the output reaches a specified value (when proper exposure is achieved) ) Is a technology that stops the flash.
<Conventional technology 5> (TTL direct dimming method)
When the light reflected from the flash and reflected by the subject passes through the taking lens and the reflected light on the film surface is measured by the photometric sensor provided on the camera body, and the output reaches a predetermined value (appropriate) This is a technology that stops the flash emission at the time of exposure.

<Conventional technology 6> (Pre-flash method)
When the release operation is performed, the flash is emitted with a small amount of light (pre-flash) at the timing prior to the shooting operation, and the reflected light from the subject at that time is measured by the photometric sensor provided on the camera body, or the image is taken When the means is an image sensor that performs photoelectric conversion, it is a technique for determining the amount of strobe light emission during the main exposure in the photographing operation from the photometric result of the image sensor.

Next, the sequence of the interval shooting operation with the digital camera will be described with reference to FIG.
In the digital camera, it is assumed that the interval shooting mode is selected and set from the menu displayed by the operation of the menu SW (SW6).
The shutter button (release shutter) (SW1) is usually a two-stage mechanical switch. The first stage (half-pressed state) signal is RL1, and the second stage (full-pressed state) signal is RL2.

As shown in FIG. 3, when the release shutter (SW1) is turned on, interval shooting starts. First, the set time (timer) is reset and started (step S1), and one subject is shot (step S1). Step S2).
The shooting is the same as in the normal shooting, and the FOCUS lens (7-2a) is moved based on the distance measurement result of the distance measurement unit (5) to focus, and when the output of the image sensor reaches a predetermined level. The integration operation is completed to complete exposure, and signal processing is performed to obtain image data.

Then, the brightness determination unit (104-1a) determines the brightness of the image from the obtained image data (step S3), and if the brightness of the image is within a predetermined range (for example, −0 for proper exposure). (5 EV to +0.5 EV range) (step S4: YES), the image is recorded in the memory as it is (step S7).
If it is out of the predetermined range (step S4: NO), the photographing condition change instructing section (104-1b) is an element related to exposure (photographing conditions) (aperture, shutter speed, image sensor sensitivity, flash light emission amount, etc.). The re-shooting instruction unit (104-1c) instructs re-shooting under the changed shooting conditions and executes re-shooting (step S6). ).

  As a matter of course, the amount to be changed at this time is determined by the amount corresponding to the difference between the brightness of the image obtained by the first shooting and the target brightness and the brightness of the subject at the second shooting. Then, the second shot image is recorded in the memory.

Next, it is determined whether or not the memory is full (step S8). If there is still space in the memory (step S8: NO), it is determined whether or not the interval shooting stop operation has been performed (step S9). The interval shooting stop operation is, for example, that the OKSW (SW12) is pressed or the power SW (13) is turned off.
If the stop operation has not been performed (step S9: NO), it is next determined whether or not the interval time has passed (step S10). If not (step S10: NO), the interval shooting stop operation has been performed. Returning to the determination of whether it has been performed (step S9), if it has elapsed, the process returns to the timer reset start and the next shooting is performed (step S10: YES).
When the memory is determined (step S8), if there is no space in the memory or a stop operation is performed (step S8: YES), the interval shooting is terminated (step S11).

In FIG. 3, when there is a failed shooting and re-shooting, the image to be recorded is only the one at the time of re-shooting, but when the camera is set to record all the shot images, As shown in FIG. The operation of the step number (for example, step S1) shown in FIG. 4 is the same as the operation of the same step number shown in FIG.
That is, as shown in FIG. 4, the image taken in step 2 is immediately recorded (step S2A), the brightness of the image is determined (step S3), and the same processing as shown in FIG. (Step S4 to Step S11).
3 and 4, the interval shooting is finished when the memory is full or the stop operation is performed. If the number of shots can be set in advance, the set number of shots is finished. Then it will end.

FIG. 5 is a flowchart showing a sequence of the self-timer photographing operation.
In the digital camera, it is assumed that the self-timer shooting mode is selected and set from the menu displayed by the operation of the menu SW (SW6).
As shown in FIG. 5, when the release shutter (SW1) is turned on, self-timer shooting starts (step S21). First, a display that the self-timer shooting is in operation is performed by turning on or blinking the self LED (11). (Step S22). In general, after displaying for about 10 seconds, shooting is performed.

  Next, it is determined whether an operation for canceling the self-timer photographing has been performed (step S23). If it has not been canceled (step S23: NO), it is determined whether a predetermined time has elapsed (step S24). If the predetermined time has not elapsed (step S24: NO), the process returns to the determination of whether or not the self-timer shooting cancellation operation has been performed (step S23). If the predetermined time has elapsed (step S24: YES), shooting is performed. Is performed (step S25). When the operation for canceling the self-timer shooting is performed (step S23: YES), the self-timer shooting is ended (step S32).

  Hereinafter, the procedure from the determination of the brightness of the captured image (step S26) to the end (end) is basically the same as that in FIG. (Step S28). For example, the self-LED (11) is turned on or blinked for about 2 seconds, the photographing condition is corrected and changed (step S29), and photographing is performed (step S30).

FIG. 6 is a flowchart for explaining the remote control photographing operation.
As shown in FIG. 6, the shooting operation is the same as the self-timer shooting operation of FIG. 5 (steps S44 to S50) except that the shooting operation is started by the remote controller (steps S41 to S43 and step S51). Same as step S25 to step S31 in FIG. 5).
In addition, timer shooting, which takes a picture when the set time comes, can be explained in the same way as self-timer shooting, and shooting by remote control regardless of wired or wireless other than the remote control also has a different form of giving the start of the shooting operation Can be explained just like remote control shooting.

In the above description of the operation, the re-photographing warning display is performed by the LED, but other visual methods or sound display (auditory display) by a speaker or the like may be used. Also, a warning may be displayed even during the interval shooting operation of FIG. In this case, it is also effective to display on the LCD monitor other than the above method.
Regarding re-shooting, in the above example, if the brightness of the first shot image is not appropriate, re-shooting is performed and the image is recorded. The determination may be made, and if not appropriate, the image may be taken again.
