(Embodiment 1)

  1 is an external view of a camera according to the first embodiment, FIG. 2 is a cross-sectional view of a lens unit 12 and an AF auxiliary light projecting unit 16, and FIG. 3 is a front view showing an arrangement of the AF auxiliary light projecting unit 16. It is.

  The camera 10 of this embodiment is configured as a digital camera including a camera body 11 and a lens unit 12 provided inside the camera body 11. The electrical configuration of the imaging unit and the like will be described later.

  A shutter button 13 and a main switch 14 are disposed on the upper surface of the camera body 11, and the lens unit 12, the strobe flash unit 15, and the AF auxiliary light projecting unit 16 are disposed on the front surface. A liquid crystal monitor 17 is disposed on the back side.

  The lens unit 12 is an assembly part including an optical member (lens) that refracts incident subject light to form a subject image on the exit side. The lens unit 12 of the present embodiment is configured as a lens unit in which the lens does not protrude from the camera body 11 during shooting.

  The shutter button 13 is an operation member operated by the photographer, and the subject image is recorded as image data when the photographer presses it down with a finger or the like. The shutter button 13 has two states: half-pressed and fully-pressed. When the photographer turns on the power of the camera 10, the captured subject image is displayed on the liquid crystal monitor 17 as a live view image. In this state, when the photographer presses the shutter button 13 halfway, photometry for exposure control, distance measurement for focus adjustment, and lens driving are performed, and the exposure and focus position are determined. When the photographer fully presses the shutter button 13, the image data of the subject image picked up at that time is read out and recorded in a memory card to be described later. The above-described exposure control and focus adjustment determination methods and procedures are merely examples, and the present invention is not limited to these examples.

  The main switch 14 is an operation member operated by the photographer, and is a switch for turning on / off the power of the camera 10.

  The stroboscopic flash unit 15 is a stroboscopic device that emits stroboscopic light for illuminating a subject at night or indoor shooting. The stroboscopic flash unit 15 controls light emission and non-light emission automatically or by user settings.

  The AF auxiliary light projecting unit 16 is a light projecting device that illuminates when the luminance or contrast of the subject is low and irradiates the subject with AF auxiliary light (hereinafter referred to as “light” as appropriate). The light emitted from the AF auxiliary light projector 16 is reflected by the subject, and the focus of the lens is adjusted by detecting this with the camera 10.

  Here, the structure of the AF auxiliary light projector 16 will be described. As shown in FIG. 2, the AF auxiliary light projecting unit 16 is irradiated from the light projecting window 16a fitted in the front surface of the camera body 11, a light emitting element 16b serving as a light source of AF auxiliary light, and the light emitting element 16b. And a reflector 16c that guides the reflected light toward the light projection window 16a. Since this AF auxiliary light projector 16 is provided in the vicinity of the lens unit 12, when the photographer's finger 18 enters the imaging area of the lens unit 12 as an obstacle, the AF auxiliary light projector The 16 light projection windows 16 a are covered with at least a part of the finger 18. When AF auxiliary light is irradiated from the AF auxiliary light projecting unit 16 in this state, a part of this light is reflected by the finger 18 and the reflected light enters the lens unit 12. For this reason, when the subject image incident from the lens unit 12 is captured, the finger 18 illuminated by the AF auxiliary light is reflected in a part of the image.

  The AF auxiliary light projector 16 is provided in the vicinity of the lens unit 12 and in an area where an obstacle such as the photographer's finger 18 is easily accessible. Specifically, as shown in FIG. 3, the center (optical axis) of the lens unit 12 as viewed from the subject side at the camera position when the photographer takes a horizontally long image with the optical axis A of the lens unit 12 being horizontal. It is provided in a region on the right side of (A) (shaded portion in the figure).

  The AF auxiliary light projecting unit 16 in the present embodiment irradiates the AF auxiliary light in order to detect the above-described function of irradiating the AF auxiliary light when the brightness and contrast of the subject are low and the finger catch at the time of shooting. It has a function as an optical part. Of these, AF auxiliary light is automatically emitted when the luminance and contrast of the subject are low, and AF auxiliary light for detecting finger catching is emitted every time the shutter button 13 is half-pressed during shooting.

  Note that if the finger catches when the luminance or contrast of the subject is low, the AF auxiliary light may not reach the subject correctly, and accurate focus adjustment may not be possible. However, when a finger catch is detected, a warning is given to the photographer by a buzzer sound as will be described later. Therefore, the finger catch is avoided by removing the finger from the AF auxiliary light projector 16. At the same time, the AF auxiliary light is normally irradiated.

  The liquid crystal monitor 17 is a display device that displays a still image of a subject image captured by an imaging unit, a live view image, icons indicating various modes and menus, and the like.

  In addition to the above, the camera 10 is provided with various operation members such as dials, levers, switches, etc., but their illustration and description are omitted.

  FIG. 4 is a block diagram showing an electrical configuration of the camera 10. Hereinafter, each part will be described.

  The lens unit 12 includes a lens 12a that is an optical member. The subject light incident on the lens unit 12 is refracted by the lens 12a, and a subject image is formed on the light receiving surface of the imaging unit 21 on the exit side. The lens 12a shown in FIG. 4 schematically shows a lens group composed of a plurality of lenses. In the bent optical lens unit in which the lens 12a does not protrude from the camera body 11 during shooting, a lens group is arranged in the Y direction in FIG. 1 (the lens arrangement is different from that in FIG. 2).

  The imaging unit 21 includes a plurality of solid-state imaging elements (not shown) arranged in a plane. The subject image formed by the lens 12a is imaged on the light-receiving surface of the solid-state imaging element at a predetermined sampling period, and is converted into an image signal. The image is converted and output to the image processing unit 22.

  The image processing unit 22 is a circuit that performs processing such as noise removal, A / D conversion, color correction processing, size change, and encoding on the image signal output from the imaging unit 21 to create digital image data. is there.

  The imaging unit 21 and the image processing unit 22 function as an imaging unit that electronically captures the subject image formed by the lens unit 12 and outputs the image as image data.

  The EEPROM 23 is a non-volatile memory that retains stored information even when the power of the camera 10 is turned off, and stores input information such as user settings and custom settings.

  The ROM 24 stores not only programs necessary for the operation and control of the camera 10, but also initial values and setting values necessary for executing the programs.

  The DRAM 25 is a volatile memory from which information stored when the power of the camera 10 is turned off is erased, and data necessary mainly when the image processing unit 22 and the control unit 29 perform processing is temporarily stored. Is done. The image data and the like are stored in the DRAM 25. That is, the DRAM 25 functions as a storage unit that stores image data acquired from the imaging unit.

  The memory card I / F (interface) unit 26 is a writing / reading device having a function of recording captured image data in the memory card 30 and reading out the image data recorded in the memory card 30. A memory card 30 is detachably mounted in a memory card slot (not shown) of the memory card I / F unit 26. Note that, when the memory card 30 is not attached to the camera 10, image data captured in a built-in memory (not shown) is recorded.

  The power supply circuit 27 is a circuit that supplies electric power output from a power supply device (not shown) according to the operating state of each unit. The power supply by the power supply circuit 27 is controlled by the control unit 29.

  The warning unit 28 is a circuit that issues a buzzer sound to warn the photographer when a finger catching on the lens unit 12 is detected. The buzzer sound may be stopped after being sounded for a predetermined time, or may be sounded a predetermined number of times.

  The control unit 29 is a circuit that controls the operation of the entire camera 10 and is configured by a microprocessor. Various signals and data transmitted from operation members such as the shutter button 13 and the main switch 14 are input to the control unit 29.

  Further, the control unit 29 acquires image data of a detection area, which will be described later, set in the imaging area when the AF auxiliary light projecting unit 16 is turned on and off, and the luminance data included in the acquired image data. Based on the difference (difference value), it functions as detection means for detecting the approach of an obstacle such as a photographer's finger. Here, when the AF auxiliary light is turned on and off, the average luminance in the detection area is obtained from the luminance data included in the acquired image data, and the luminance difference between the average luminances is calculated. If the luminance difference is less than a preset threshold value, it is determined that there is no finger hold, and if it is equal to or greater than the threshold value, it is determined that there is a finger hold.

  In the present embodiment, when the control unit 29 detects a finger catch, the warning unit 28 sounds a buzzer to warn the photographer.

  Further, when the power of the camera 10 is turned on, the control unit 29 displays the captured subject image on the liquid crystal monitor 17 as a live view image. When the shutter button 13 is half-pressed in this state, photometry for exposure control, distance measurement for focus adjustment, and lens driving are performed to determine the exposure and focus position. Further, when the shutter button 13 is fully pressed, the image data of the subject image captured by the imaging unit 21 at that time is read and recorded in the memory card 30 as the imaging process.

  Next, a processing procedure for detecting finger touch at the time of shooting in the control unit 29 will be described with reference to the flowchart of FIG. The processing by this routine starts when the camera 10 is turned on.

  First, when half-pressing of the shutter button 13 is detected in step S101, in step S102, the control unit 29 turns on the AF auxiliary light projecting unit 16 and irradiates AF auxiliary light (hereinafter referred to as AF auxiliary light). Is appropriately referred to as “lighting of AF auxiliary light”). Next, in step S103, the control unit 29 performs photometry for exposure control based on the image data of the subject imaged by the imaging unit (the imaging unit 21 and the image processing unit 22). Subsequently, in step S104, distance measurement (and lens driving) for focus adjustment is performed based on the imaged image data.

  In step S105, luminance data (1) included in the image data of the detection area set in the imaging area is acquired from the image data captured at the time of lighting. In the subsequent step S106, the AF auxiliary light projecting unit 16 is turned off and the AF auxiliary light is not irradiated (hereinafter, non-irradiation of the AF auxiliary light is appropriately referred to as “off of the AF auxiliary light”). In step S107, luminance data (2) included in the image data of the detection area set in the imaging area is acquired from the image data captured when the light is turned off.

  Here, the luminance data (1) and (2) will be described. 6A and 6B are explanatory diagrams showing detection areas and finger catches set in the imaging area. In FIGS. 6A and 6B, a solid line range indicated by reference numeral 100 is an imaging area, and a broken line range indicated by reference numeral 100a indicates a finger catching detection area. In this embodiment, when the subject direction is viewed from the photographer side, an area that is on the upper left side of the imaging area 100 is set as the detection area 100a. That is, when the photographer holds the camera 10, the finger of the photographer's left hand can easily approach the lens unit 12, and an area corresponding to this area on the upper left side of the photographing area 100 is set as the detection area 100 a. is doing.

  As shown in FIG. 6A, when the AF assist light is irradiated with the photographer's finger 18 entering the detection area 100a, the finger 18 is illuminated with the AF assist light and becomes brighter. For this reason, the average brightness | luminance of the brightness | luminance data contained in the image data of the detection area | region 100a becomes high. On the other hand, as shown in FIG. 6B, when the AF assist light is not irradiated while the photographer's finger 18 enters the detection area 100a, the finger 18 is not illuminated by the AF assist light. The average luminance of the luminance data included in the image data of the same detection area 100a is lower than (a). In particular, when the penetration of the finger is large, the finger portion becomes a shadow, so the average luminance is lower than (a). Therefore, when the finger 18 enters the detection area 100a, there is a large difference in the average luminance of the luminance data included in the image data of the detection area 100a between when the AF auxiliary light is irradiated and when the finger is not irradiated. It will be.

  On the other hand, in a state where nothing enters the detection area 100a, the average luminance of the luminance data included in the image data of the detection area 100a is almost changed between when the AF auxiliary light is irradiated and when it is not irradiated. Will not occur.

  Returning to the description of the flowchart of FIG. 5 again, in step S108, the control unit 29 calculates the luminance difference between the luminance data (1) and (2) acquired in steps S105 and S107 as a difference value. In step S109, it is determined whether the difference value is less than a preset threshold value. If the difference value is greater than or equal to the threshold value, it is determined that there is a finger and the process proceeds to step S110. In step S110, as a warning process, a buzzer is sounded to give a warning to the photographer.

  On the other hand, if the difference value is less than the threshold value in step S109, it is determined that there is no finger and no warning process is performed. Subsequently, when the full press of the shutter button 13 is detected in step S111, in step S112, the control unit 29 reads image data of the subject image captured at that time as an imaging process. In step S113, the read image data is recorded in the memory card 30 as a recording process, and the process according to this routine ends.

As mentioned above, according to Embodiment 1, there exist the following effects.
(1) Since the image data of the detection region is acquired when the AF auxiliary light is turned on and off, and the finger catching is detected based on the luminance difference of the luminance data included in the image data. Complex arithmetic processing is not required. For this reason, it is possible to quickly determine the finger catch. Further, since it is not necessary to store a pattern image for comparison, the capacity of the storage medium can be used effectively.
(2) It is not necessary to provide a special mechanism such as a movable infrared transmission filter and can be realized with an existing configuration, so that an increase in cost can be avoided.
(3) The AF auxiliary light projector 16 is positioned on the right side of the center of the lens unit 12 when viewed from the subject side at the camera position when the photographer shoots a horizontally long image with the optical axis A of the lens unit 12 being horizontal. Therefore, more AF auxiliary light can be applied to the photographer's finger on the lens unit 12. According to this, since the photographer's finger can be effectively illuminated, the luminance difference between when the AF auxiliary light is turned on and when it is turned off can be increased. For this reason, it is possible to more accurately determine finger catching.
(Embodiment 2)

  The second embodiment is characterized in that the AF auxiliary light is turned on and off continuously for a predetermined number of times. The control unit 29 in the present embodiment obtains the luminance difference of the luminance data included in the acquired image data of the detection region 100a every time the AF auxiliary light projecting unit 16 is turned on and off, and stores it in the DARM 25. It functions as a detecting means for detecting the approach of an obstacle based on the average value of the luminance differences stored for a predetermined number of times. In the second embodiment, the average luminance in the detection region 100a (see FIG. 6) is obtained from the luminance data, and the luminance difference between the average luminance when the light is on and when the light is off is calculated. If the average value of the luminance difference for a predetermined number of times is less than a preset threshold value, it is determined that there is no finger hold, and if it is equal to or greater than the threshold value, it is determined that there is a finger hold. Note that the number and interval of continuous AF auxiliary light turning on and off can be set as appropriate.

  The timing at which the AF auxiliary light is turned on and off needs to be synchronized with the sampling period of the imaging unit 21. This is because, if not synchronized, when switching on / off, there is a possibility that the captured luminance value cannot be used for judgment, and for example, data for several frames of the CCD output must be deleted. However, by synchronizing the turn-on / off timing with the sampling period of the imaging unit 21, it is possible to minimize unusable data, thereby shortening the processing sequence.

According to the second embodiment, the AF auxiliary light is turned on and off continuously for a predetermined number of times. Therefore, when a photographer's finger enters the photographing area instantaneously, it is not detected as a finger hook. become. Accordingly, it is possible to improve the detection accuracy of finger catching.
(Embodiment 3)

  The third embodiment is characterized in that the AF auxiliary light is continuously turned on and off a predetermined number of times. That is, in the AF auxiliary light projecting unit 16, the time interval from turning on and turning off the AF auxiliary light and the time interval from turning off to the next lighting are set to be aperiodic, and this is continuously performed a predetermined number of times. (Lighting / lighting time can be the same).

According to the third embodiment, since the AF auxiliary light is continuously turned on and off a predetermined number of times, for example, the luminance change of the subject in which a flashing light or the like exists in the background, and the photographer Can be accurately determined. In other words, since the blinking of lights installed outdoors is periodic, if this cycle matches the cycle of turning on / off the AF auxiliary light, the background brightness change will be used as an indicator. It may be judged. However, in the present embodiment, since the lighting and extinguishing of the AF auxiliary light is aperiodic, the possibility that the cycle of turning on / off the AF auxiliary light coincides with the cycle of the flashing light is extremely low. Therefore, by calculating the luminance difference of the average luminance between when the AF auxiliary light is turned on and off, and calculating the average value of the luminance difference for a predetermined number of times, it becomes less susceptible to the luminance change of the flashing light. Therefore, it is possible to accurately determine the luminance change of a subject in which a flashing light or the like exists in the background and the photographer's finger hold.
(Embodiment 4)

  The fourth embodiment is characterized in that finger catching is determined based on a luminance difference between color components included in image data. The control unit 29 in the present embodiment obtains the average luminance of each of the R, G, and B color components included in the image data of the detection area 100a when the AF auxiliary light is turned on and off, and the luminance of the R color component If the difference is greater than or equal to a preset threshold value and the luminance difference between the G and B color components is less than the preset threshold value, it is determined that there is a finger hold, and otherwise it is determined that there is no finger hold. ing.

  In the present embodiment, since the AF auxiliary light is red, it is a requirement for determination that the luminance difference in the R color component is equal to or greater than a preset threshold. However, light of other colors is emitted. In this case, the luminance difference between the color components including the color is used as a determination requirement.

According to the fourth embodiment, the determination of the finger hold is performed based on the luminance difference between the color components included in the image data. Therefore, the determination of the finger hold can be performed without being affected by the brightness or the luminance change of the background. It can be performed. Therefore, it is possible to detect finger catch more accurately.

However, the projecting unit of the present invention is in the vicinity of the lens unit 12. Further, any light source may be used as long as it is provided in an area where an obstacle is easily approached at the time of photographing and has a function of irradiating light toward the subject side when it is turned on. For example, an existing red-eye reduction lamp or a self-timer lamp can be used. These lamps may be used together with the AF auxiliary light projector 16 or may be provided alone. Moreover, you may provide the lamp | ramp used as the exclusive light projection part for detecting a finger hook.

(2) In the above embodiment, when a finger catch is detected, the warning unit 28 sounds a buzzer sound. However, a warning may be issued by other methods.

Further, an icon or a message for notifying the finger hold on the liquid crystal monitor 17 may be displayed. These display warnings may be used in combination with a buzzer or may be combined as appropriate.

(3) When a finger catch is detected, an operation by fully pressing the shutter button 13 may be invalidated, and a finger catch warning may be issued by a buzzer sound or display in a state in which shooting is not possible. In addition, a finger warning may be issued by a buzzer sound or display after shooting, not before shooting. As described above, the method of issuing a warning after shooting is effective when utilizing a part of information included in the shot image, and the photographer can shoot without missing a photo opportunity.
