Abstract

(57) [Summary] (Modified) [Problem] With a camera equipped with a self-photographing mode in which the photographer shoots himself, usually many right-handed photographers themselves hold the camera with their left hand to shoot. Also, in the camera hold position, it is normal to tighten the side of the arm to shoot and make it difficult to cause camera shake, but in self shooting mode, extend one hand and press the release button to perform the release operation I was shooting, and it often resulted in camera shake. When a photographer sets a mode for photographing himself, the photographing mode changing means includes a shutter release delay means for performing a photographing operation after a predetermined time after pressing a shutter release button. The shutter release delay mode is automatically set to prevent camera shake.

The shutter control of No. 3 is performed. Photometry of the object is performed by a photometry circuit 104, and a photometry output is sent to the microcomputer 101 under the control of the microcomputer 101. Then, the microcomputer 101 performs A / D conversion on the sent photometric output, and uses it for calculating exposure conditions (aperture, shutter speed). Reference numeral 106 denotes a distance measuring circuit block which receives a control signal from the microcomputer 101, and a light projecting circuit (not shown) projects a signal light of a predetermined light amount and a predetermined wavelength to a subject by a light projecting element. A light receiving sensor (not shown) forms an image of reflected light from a subject on a sensor such as a multi-segmented silicon photocell (SPC) or a semiconductor position detecting element (PSD). Further, a distance measurement calculation circuit (not shown) calculates an output from the light receiving sensor and transmits the output to the microcomputer 101 as a subject distance.

Reference numeral 106 denotes a feeding circuit for controlling a feeding motor, which feeds a film (not shown) (winding and rewinding) according to a control signal of the microcomputer 101. 1
Reference numeral 07 denotes a lens drive circuit including a motor for moving the photographing lens based on the result of the distance measurement operation circuit 106.

Reference numeral 108 denotes a limiting resistor for limiting the current of the display LED, and reference numeral 109 denotes an AF display LED for notifying the photographer of the completion of distance measurement and a short distance warning. Reference numeral 110 denotes a limiting resistor for limiting the current of the display LED. Reference numeral 111 denotes an LLT display LED that blinks or turns on when the microcomputer 101 determines that the luminance is low based on the output of a photometry circuit (not shown). 112 and 1
A switch 13 is linked to the release button. When the switch 13 is pushed down to the first stroke, the switch 13 is turned on, and a shooting preparation operation such as AF or photometric calculation is started. In the camera of the present embodiment, the release button is configured as a two-stage press-in type,
The switch 112 is turned on when the first step is pressed, and the switch 113 is turned on when the second step is pressed. The switch 114 is a switch for setting a self-photographing mode. The switch 115 is an automatic shutter release delay release switch, and the switch 116 is a self-timer time setting switch in the self-photographing mode.

Next, the operation will be described. FIG. 2 is a flowchart mainly showing a control sequence by the microcomputer 101. Hereinafter, the operation of the camera will be described with reference to FIG. In addition, in each of the following flows, each step is indicated by “S”.

First, the microcomputer 101 initializes various flags and the like (S201). Then, the process proceeds to the next step, and it is determined whether or not the self-photographing mode is set by the self-photographing mode setting switch 114 (S2).
02). When the self-photographing mode is set in S202, the self-timer photographing as shutter release delay means is automatically set (S203).

In the next step S204, it is determined whether or not the switch SW1 (switch 112) is turned on. If not, the process stands by in this step. Thereafter, when SW1 (switch 112) is turned on, the process proceeds to S205, the microcomputer 101 performs a battery check, and when the battery is insufficient for performing the next operation,
A series of operations ends. If the battery is sufficient, the process proceeds to S206, where the microcomputer 10
Numeral 1 instructs a light emitting circuit (not shown) to emit light at a predetermined light amount and a predetermined wavelength, and a light emitting element (not shown) starts emitting light. This projection light is projected onto a subject and is imaged on a light receiving sensor (not shown). The light receiving sensor outputs a signal in accordance with the image forming position, converts the signal into a signal corresponding to a subject distance by a distance measurement operation circuit, and transmits the signal to the microcomputer 101 to perform a distance measurement operation. In step S207, the photometric circuit is driven to perform a photometric operation.
At 208, the lens drive circuit 107 adjusts the focus of the photographing lens based on the distance measurement information obtained by the distance measurement device.

In the next step S209, it is determined whether or not the switch SW2 (switch 113) is on. If not, the process waits at this step. SW2 (switch 11)
If 3) is on, the countdown of the self-timer shooting starts in S210.

In step S211, the shutter control circuit 102 is driven to perform an exposure operation. Subsequent S212
In, the film is wound by the feeding circuit 106,
A series of operations ends.

If the self-photographing mode is not set in step S202, the process advances from step S204 to step S212 to end a series of operations.

FIG. 3 is a flowchart of the camera according to the second embodiment of the present invention. First, the microcomputer 101 initializes various flags and the like (S30).
1). Then, the process proceeds to the next step, and it is determined whether or not the self-photographing mode is set by the self-photographing mode setting switch 114 (S302). When the self-photographing mode is set in S302, it is determined whether or not to set the self-timer photographing (S303). If the operation of the shutter release delay unit is prohibited in S303, the automatic shutter release delay release switch 115 shown in FIG. 1 is operated (ON) to release the self-timer shooting, and it is determined whether or not SW1 is ON in S305. Make a decision.
If the self-timer shooting is set in S303, the countdown time of the self-timer is set arbitrarily by the self-timer time setting switch 116 in S304, and the process proceeds to S305. Hereinafter, the same operations as in FIG. 2 are performed from step 305 to step 313, and a series of operations is completed.

The above is the correspondence between each component of the present invention and each component of the embodiment. However, the present invention is not limited to the configuration of these embodiments. Although the self-timer setting means is described as the delay means, it is also possible to use the remote control setting means as the release delay means, so long as the function described in the claims or the function of the configuration of the embodiment can be achieved. It goes without saying that any kind of object may be used.

[0023]

As described above, according to the present invention,
In a camera equipped with a mode in which the photographer takes a picture of himself / herself, when the self-portrait mode is set, the shutter release is automatically delayed, self-timer photography or remote control photography is performed, and the release operation is performed a predetermined time after the release button is pressed. By doing so, it is possible to eliminate camera shake photos caused by pressing the release button.

The self-timer in the self-photographing mode can be arbitrarily set for the predetermined time, so that a camera having a self-photographing mode that is easy to use can be provided.

Further, in the self-photographing mode, when the self-timer photographing is unnecessary, it can be canceled, thereby improving the usability of the photographer.
