Description

  The present invention relates to a photographing apparatus and a focus information display control method.

  There is known an imaging apparatus capable of displaying information indicating a focused state on a display unit. For example, Patent Document 1 describes a specific configuration of this type of photographing apparatus.

  The imaging apparatus described in Patent Document 1 acquires the focus rate (a value indicating the degree of focus) of a subject in each predetermined confirmation area for an image that is focused by autofocus, and the focus rate is greater than or equal to a reference value. By displaying the focus frame and the focus rate for a certain confirmation area, it is possible to notify the user how much the subject in which part of the photographing area has been focused.

JP 2009-88722 A

  In some photographing apparatuses including the photographing apparatus described in Patent Document 1, focus can be adjusted not only by autofocus but also by manual operation. Thus, for example, consider a case in which focus adjustment is performed by manual operation after autofocusing in the photographing apparatus described in Patent Document 1. In this case, according to the result of autofocus, the focus frame and the focus rate are displayed on the display screen of the photographing apparatus for the confirmation area where the focus rate is equal to or higher than the reference value. However, even if the focus is subsequently changed by a manual operation, information notifying the fact is not displayed on the display screen. Therefore, a problem is pointed out that it is difficult for the user to grasp that the focus has been changed by manual operation since autofocus.

  Therefore, an imaging apparatus according to an embodiment of the present invention is based on a focus state detection unit that detects a focus state of a subject captured in a shooting region for a plurality of areas, and a detection result by the focus state detection unit. Display control means for displaying information relating to the in-focus state on a subject on a predetermined display unit, and manual focus means for changing the focus of the photographing optical system in accordance with a predetermined manual operation by the user. The configuration. When the focus of the photographic optical system is changed by manual operation, the display control means changes the focus information for the area having a high focus level before the focus is changed to the focus level after the focus is changed. Regardless, it is displayed in a distinguishable manner before the focus is changed.

  An imaging apparatus according to an embodiment of the present invention includes an autofocus unit that automatically focuses on a subject by driving and controlling the imaging optical system based on a detection result by the focus state detection unit. Also good. In this case, when the focus is adjusted to the subject by the autofocus means, the display control means displays information on the focus in the area of the focused subject, and the focus adjusted by the autofocus means is changed by manual operation. If so, the display of information on the in-focus state may be updated according to the changed focus.

  In one embodiment of the present invention, when the auto-focus means focuses on two or more areas, the display control means displays the two or more areas as in-focus candidate areas. When the candidate area with the highest degree of focus is displayed so as to be distinguishable from other candidate areas, and the focus adjusted by the autofocus means is changed manually, the focus of the two or more candidate areas is changed. A configuration may be adopted in which the candidate area with the highest degree of focus is displayed so as to be distinguishable from other candidate areas later.

  In one embodiment of the present invention, the display control means displays information on the in-focus state at the time of focusing on the subject by the autofocus means, erases the display of the information, and then performs a manual operation. In addition, information regarding the focus state that was displayed at the time of the final focusing by the autofocus unit may be displayed again.

  In one embodiment of the present invention, the autofocus means may be configured to automatically focus on the subject by driving and controlling the photographing optical system when a predetermined autofocus operation is performed by the user. The display control means may be configured to display information related to the in-focus state in accordance with execution of the autofocus operation.

  In one embodiment of the present invention, the display control means displays information relating to the in-focus state from the start time or end time of the autofocus operation, and when the first time has elapsed since the display was performed. The display is erased, information about the in-focus state is displayed from the time of manual operation, and the display is erased when a second time longer than the first time has elapsed since the display was performed. It is good also as composition to do.

  Further, in one embodiment of the present invention, the display control means may be configured to display information regarding the in-focus state in different ways depending on whether the autofocus operation is performed or the manual operation is performed. .

  Further, in one embodiment of the present invention, the display control means, as information about the in-focus state, for the target area, the color of the frame indicating the area, the line width of the frame, the line type of the frame, the hue of the area In addition, one having a combination of one or two or more of saturation, chromaticity, brightness, and a character string, pattern, figure to be overlaid in the area may be displayed. In this case, the display form of the target area may be different when the autofocus operation is performed and when the manual operation is performed.

  The imaging apparatus according to an embodiment of the present invention further includes a holding unit that holds information on an area with a high degree of focus when the subject is focused on by the autofocus unit after a predetermined starting point. It is good also as a structure. In this case, when the manual operation is performed, the display control unit refers to the holding unit, and when the autofocus unit focuses on the subject after the predetermined starting point, the display control unit uses the autofocus unit. After displaying information related to the focus state in the area where the degree of focus was high at the time of the final focus, the display of the information related to the focus state is updated according to the focus after being changed by manual operation. Thereafter, when focusing on the subject by the autofocus means is not performed, information regarding the in-focus state may be displayed for all areas with a high degree of focus.

  In addition, a focus information display control method according to an embodiment of the present invention relates to a step of detecting a focus state of a subject captured in a shooting region for a plurality of areas, and a focus state based on a detection result. When the information is superimposed on the subject and displayed on a predetermined display unit, the step of changing the focus of the photographing optical system according to a predetermined manual operation by the user, and the focus of the photographing optical system is changed by the manual operation, the focus is changed. Including a step of displaying information relating to focusing on an area having a high degree of focus before being changed regardless of the degree of focus after the focus is changed, so as to be distinguishable from before the focus is changed. .

The apparatus may be replaced with another type of apparatus having a photographing function.

[Configuration of the photographing apparatus 1]
FIG. 1 is a block diagram showing a configuration of the photographing apparatus 1 of the present embodiment. As shown in FIG. 1, the photographing apparatus 1 includes a system controller 100, an operation unit 102, a drive circuit 104, a photographing lens 106, a diaphragm 108, a shutter 110, a solid-state image sensor 112, a signal processing circuit 114, an image processing engine 116, A buffer memory 118, a card interface 120, an LCD (Liquid Crystal Display) control circuit 122, an LCD 124, and a ROM (Read Only Memory) 126 are provided. Although the photographing lens 106 has a plurality of lenses, it is shown as a single lens for convenience in FIG.

  The operation unit 102 includes various switches necessary for the user to operate the photographing apparatus 1, such as a power switch, a release switch, and a photographing mode switch. When the user operates the power switch, power is supplied from the battery (not shown) to the various circuits of the photographing apparatus 1 through the power line.

  The system controller 100 includes a CPU (Central Processing Unit) and a DSP (Digital Signal Processor). After supplying power, the system controller 100 accesses the ROM 126, reads out a control program, loads it into a work area (not shown), and executes the loaded control program to control the entire photographing apparatus 1.

  When the release switch is operated, the system controller 100 is measured by, for example, a photometric value calculated based on an image captured by the solid-state image sensor 112 or an exposure meter (not shown) built in the photographing apparatus 1. The diaphragm 108 and the shutter 110 are driven and controlled via the drive circuit 104 so that proper exposure can be obtained based on the photometric values. More specifically, drive control of the aperture 108 and the shutter 110 is performed based on an AE function designated by a shooting mode switch such as a program AE (Automatic Exposure), shutter priority AE, aperture priority AE, and the like. Further, the system controller 100 performs AF (Autofocus) control together with AE control. An active method, a phase difference detection method, a contrast detection method, or the like is applied to the AF control. The AF mode includes a central single-point ranging mode using a single central ranging area, a multi-point ranging mode using a plurality of ranging areas, and the like. The system controller 100 controls driving of the photographing lens 106 via the driving circuit 104 based on the AF result, and adjusts the focus of the photographing lens 106. Since the configuration and control of this type of AE and AF are well known, detailed description thereof is omitted here.

  The light flux from the subject passes through the photographing lens 106, the diaphragm 108, and the shutter 110 and is received by the light receiving surface of the solid-state image sensor 112. The solid-state imaging device 112 is a single-plate color CCD (Charge Coupled Device) image sensor having a Bayer pixel arrangement. The solid-state imaging device 112 accumulates an optical image formed by each pixel on the light receiving surface as a charge corresponding to the amount of light, and generates R (Red), G (Green), and B (Blue) image signals. Output. The solid-state image sensor 112 is not limited to a CCD image sensor, and may be replaced with a CMOS (Complementary Metal Oxide Semiconductor) image sensor or other types of imaging devices. The solid-state image sensor 112 may also have a complementary color filter mounted thereon.

  The signal processing circuit 114 performs predetermined signal processing such as clamping and demosaicing on the image signal input from the solid-state imaging device 112 and outputs the processed signal to the image processing engine 116. The image processing engine 116 performs predetermined signal processing such as matrix operation, Y / C separation, and white balance on the image signal input from the signal processing circuit 114 to generate a luminance signal Y and color difference signals Cb and Cr. , And compressed in a predetermined format such as JPEG (Joint Photographic Experts Group). The buffer memory 118 is used as a temporary storage location for processing data when the image processing engine 116 executes processing. Further, the storage format of the captured image is not limited to the JPEG format, and may be a RAW format in which only minimal image processing (for example, black level correction) is performed.

  A memory card 200 is detachably inserted into a card slot of the card interface 120.

  The image processing engine 116 can communicate with the memory card 200 via the card interface 120. The image processing engine 116 stores the generated compressed image signal (captured image data) in the memory card 200 (or a built-in memory (not shown) provided in the image capturing apparatus 1).

  Further, the image processing engine 116 buffers the generated luminance signal Y and color difference signals Cb and Cr in a frame memory (not shown) in units of frames. The image processing engine 116 sweeps the buffered signal from each frame memory at a predetermined timing, converts it into a video signal of a predetermined format, and outputs it to the LCD control circuit 122. The LCD control circuit 122 modulates and controls the liquid crystal based on the image signal input from the image processing engine 116. Thereby, the photographed image of the subject is displayed on the display screen of the LCD 124. The user can view a real-time through image (live view) photographed with appropriate exposure and focus based on the AE control and AF control through the display screen of the LCD 124.

  When the user performs a reproduction operation of the photographed image, the image processing engine 116 reads the photographed image data designated by the operation from the memory card 200 or the built-in memory, converts it into an image signal of a predetermined format, and the LCD control circuit 122. Output to. The LCD control circuit 122 performs modulation control on the liquid crystal based on the image signal input from the image processing engine 116, so that a captured image of the subject is displayed on the display screen of the LCD 124.

[Focus information display processing]
FIG. 2 shows a flowchart of the focus information display process executed by the system controller 202 in an embodiment of the present invention. The focus information display process in FIG. 2 is started when, for example, an AF operation (half-pressing the release switch or pressing the AF button) is performed.

[S11 in FIG. 2 (Display of Focusing Area Frame)]
When the AF operation is performed, the photographing lens 106 is driven and controlled in an AF mode in which the focus state of the subject in the photographing region is detected for a plurality of areas, and the subject in at least one area is focused. . Note that in this specification, a subject (area) that is in focus may be rephrased as a subject (area) within the depth of field or a subject (area) with a high degree of focus.

  In this processing step S11, at least one area that is a through image displayed on the display screen of the LCD 124 and is in focus in the AF mode (hereinafter referred to as “AF focusing area”) is focused. Area frames are displayed overlapping. In this processing step S11, the focusing area frame is displayed in a color (for example, green) indicating that focusing has been performed by AF.

  Regardless of whether there are two or more in-focus area frames (in other words, whether there are two or more in-focus candidate areas), all the candidate areas may be displayed in green. The candidate area having the highest value may be displayed so as to be distinguishable from other candidate areas. Illustratively, the focus area frame of the candidate area having the highest focus degree among the two or more candidate areas is displayed in green, and the focus area frames of the other candidate areas are displayed in yellow.

[S12 in FIG. 2 (Maintaining AF Focus Area)]
In this processing step S12, information about the AF in-focus area is held in a predetermined storage area such as the buffer memory 118. Note that the information on the AF in-focus area held here disappears when the power of the photographing apparatus 1 is turned off. In other words, the information on the AF in-focus area acquired after the power is turned on is held in the predetermined storage area, and the information on the AF in-focus area acquired before that is not stored.

[S13 in FIG. 2 (determination of AF operation)]
In this process step S13, it is determined whether or not the AF operation is continued. When it is determined that the AF operation is not continued (the AF operation is ended) (S13: NO), the focus information display process in FIG. 2 is ended. In this case, in order to notify the user that the execution of the detection process of the in-focus state has stopped, the in-focus area frame is changed, for example, in red or is not displayed.

[S14 in FIG. 2 (determination of focus ring operation)]
This processing step S14 is executed when it is determined in processing step S13 (determination of AF operation) that the AF operation is continuing (AF operation is being performed) (S13: YES). In this processing step S14, it is determined whether or not the focus ring provided around the lens barrel of the photographing lens 106 has been operated. If it is determined in step S14 that the focus ring is not operated (S14: NO), the focus information display process in FIG. 2 returns to step S13 (determination of AF operation).

[S15 in FIG. 2 (Focus State Determination of AF Focus Area)]
This process step S15 is executed when it is determined in process step S14 (determination of the focus ring operation) that the focus ring has been operated (S14: YES). In this processing step S15, whether or not each AF in-focus area held in processing step S12 (holding the AF in-focus area) is in an in-focus state with the focus being changed by the focus ring operation (not yet). Whether or not it is in focus (within depth of field).

[S16 in FIG. 2 (First Determination of Focusing Operation)]
This processing step S16 is executed when it is determined in processing step S15 (determination of the focusing state of the AF focusing area) that each AF focusing area is in a focusing state (S15: YES). In this process step S16, it is determined whether or not the focus ring operation is a focus ring operation performed for the first time after the execution of the focus information display process of FIG. Such determination processing is performed using a predetermined flag (a flag that is reset at the start or before the start of the focus information display processing in FIG. 2). If it is determined in step S16 that the focus ring operation is not the focus ring operation performed for the first time after the execution of the focus information display process of FIG. 2 is started (S16: NO), the focus information display process of FIG. Then, the process returns to step S13 (determination of AF operation).

[S17 in FIG. 2 (Updating Display of Focusing Area Frame)]
This processing step S17 is performed when it is determined in the processing step S16 (first determination of the focus ring operation) that the focus ring operation is the first focus ring operation performed after the execution of the focus information display process of FIG. S16: YES). In this processing step S17, in order to notify the user that the focus is still in focus in each AF focus area, but the focus has been changed by manual operation (focusing operation) from the time of AF focus. The display of the focus area frame is updated. After execution of this processing step S17, the focus information display processing of FIG. 2 returns to processing step S13 (determination of AF operation).

  Here, display update examples (display update examples 1 and 2) of the in-focus area frame in this processing step S17 will be described.

・ Display update example 1
FIG. 3 is a diagram for explaining a display update example 1 of the focus area frame. In the example of FIG. 3, there is one focusing area frame. The focused area frame F1 displayed in green by the execution of the processing step S11 (display of the focused area frame) is changed to yellowish green by the execution of this processing step S17. Thereby, the user can grasp that the focus is still in focus in the AF focus area indicated by the focus area frame F1, but the focus has been changed by manual operation from the time of AF focus. it can.

・ Display update example 2
FIG. 4 is a diagram illustrating a display update example 2 of the focus area frame. In the example of FIG. 4, there are two in-focus area frames. In the example of FIG. 4, by executing the processing step S11 (display of the focus area frame), the focus area frame F2 of the candidate area with the highest focus degree is displayed in green, and other candidates. The focus area frame F3 of the area is displayed in yellow. Then, when the focus is changed by a manual operation, the candidate area of the focus area frame F3 has a higher degree of focus than the candidate area of the focus area frame F2. Therefore, by executing this processing step S17, the focus area frame F3 of the candidate area with the highest focus degree is changed from yellow to green, and the focus area frame F2 of other candidate areas is green. Will be changed to yellow. As a result, although the user is still in focus in the two AF in-focus areas indicated by the in-focus area frames F2 and F3, the user is in focus because the focus has been changed by manual operation from the time of AF in-focus. It can be visually recognized that the candidate area having the highest degree has changed. Display update example 2 is effective when the user wants to manually change the area that the user wants to focus on most from among a plurality of candidate areas.

[S18 in FIG. 2 (Updating Display of Focusing Area Frame)]
In this processing step S18, the AF in-focus area is not in the in-focus state in the processing step S15 (determination of the in-focus state of the AF in-focus area). It is executed when it is determined that the information is not in a state (S15: NO). In this processing step S18, the display of the focus area frame is updated according to the focus changed by manual operation from the AF focus. For example, the focus area frame of the AF focus area that is in focus after manual operation is changed to yellow-green, and the focus area frame of the AF focus area that is no longer in focus after manual operation is changed to red Or hidden.

  Here, a display update example (display update examples 3 and 4) of the in-focus area frame in this processing step S18 will be described.

・ Display update example 3
Display update example 3 will be described with reference to FIG. In the display update example 3, the focus area frame F1 is changed from green to red (or not displayed) by executing this processing step S18. Thus, the user can grasp that the focus is not achieved in the AF focusing area indicated by the focusing area frame F1 by manual operation.

・ Display update example 4
Display update example 4 will be described with reference to FIG. In the display update example 4, similarly to the display update example 2, when the processing step S11 (display of the focus area frame) is executed, the focus area frame F2 of the candidate area with the highest focus degree is displayed in green. In addition, the focus area frame F3 of the other candidate areas is displayed in yellow. In the display update example 4, since the focus is changed by a manual operation, the focus cannot be achieved in the candidate area of the focus area frame F2. Therefore, by executing this processing step S18, the in-focus area frame F3 of the candidate area with the highest focus degree is changed from yellow to green, and the in-focus area of the candidate area that is out of focus. The frame F2 is changed from green to red (or not displayed). As a result, the user can grasp how the focus in the AF in-focus area has changed as a result of the manual operation.

  The above is the description of the exemplary embodiments of the present invention. Embodiments of the present invention are not limited to those described above, and various modifications are possible within the scope of the technical idea of the present invention. For example, the embodiment of the present invention also includes contents appropriately combined with embodiments or the like clearly shown in the specification or obvious embodiments.

  In the above embodiment, the display of the focus area frame displayed on the display screen of the LCD 124 is controlled, but the present invention is not limited to this. In another embodiment, the display of a distance measuring point in the optical viewfinder provided in the photographing apparatus 1 may be controlled. FIG. 5 shows an example of display control of distance measuring points in the optical viewfinder. As illustrated in FIG. 5, when an AF operation is performed, an in-focus area (ranging point) is lit and displayed by an LED (Light Emitting Diode) or the like, and is superimposed on a subject reflected in the optical viewfinder. Is displayed. Of the ranging points that are candidates for focusing, the ranging point with the highest degree of focusing is lit in red, and the other ranging points are lit in green. Next, when the focus point with the highest degree of focus is changed to another focus point by changing the focus by manual operation, the emission color of the focus point is changed accordingly.

  In the above embodiment, the green focus area frame is displayed for the AF focus area until the AF operation is stopped after the focus is achieved, but the present invention is not limited to this. In another embodiment, some information related to the in-focus state is displayed from a predetermined time point (the start time or end time of the AF operation), and when the focus is adjusted after that, the green focus area is compared to the AF focus area. A frame may be displayed. In this case, the green focus area frame may be displayed until the AF operation is stopped, and is erased when a first time elapses from a predetermined time (the start time or end time of the AF operation). You may make it do.

  Thereafter, when the manual operation is performed, the focus area frame that was displayed at the time of the final AF focusing may be displayed again from a predetermined time (the start time or the end time of the manual operation). In this case, the display of the in-focus area frame is updated when the focus is changed by the manual operation from the AF in-focus state, and the first time is longer than the predetermined time (the start time or the end time of the manual operation). It may be deleted when the second time elapses.

  To supplement the explanation, since the manual focus adjustment is manually performed by the user, it may take longer than the automatic focus adjustment by the AF operation. In view of this, the focus area frame prevents manual display from being erased during manual operation, and suppresses power consumption due to continuation of unnecessary display (for example, power consumption due to unnecessary lighting of a distance measuring point (LED)). During the operation, the display is continued for a second time longer than the first time during the AF operation.

  Further, in the above embodiment, the information regarding the in-focus state (in the above embodiment, the in-focus area frame) is displayed by different methods during the AF operation and during the manual operation. Specifically, during AF operation, an in-focus area frame is displayed when focus is achieved, but during manual operation, when the operation is performed (that is, at the first stage), focusing at the time of AF in-focus is performed. An area frame is displayed. Thereby, the user can visually grasp whether automatic focus adjustment is performed according to the AF operation or manual focus adjustment is performed according to the manual operation.

  In the above embodiment, the focus status can be distinguished by the color of the focus area frame, but the present invention is not limited to this. Instead of the focus area frame color, for example, the focus area frame line width, line type, AF focus area hue, saturation, chromaticity, brightness, character string and pattern to be displayed in the focus area frame overlay The in-focus status may be distinguished by displaying a combination of one or more of the drawings. By displaying a completely different form between the AF operation and the manual operation, the user can determine whether the focus is automatically adjusted according to the AF operation or the manual focus is adjusted according to the manual operation. Can be clearly understood.

  In the above embodiment, the user is notified of the in-focus status by controlling the display screen of the LCD 124 and the display of the optical viewfinder, but the present invention is not limited to this. For example, it may be possible to notify the user of the in-focus status by playing a predetermined sound. In this case, the volume of the reproduced sound and the type of the reproduced sound are changed according to the status to be notified.

  In the above embodiment, the case where the manual operation is performed after the AF operation is performed after the predetermined starting point (after power-on) has been described. However, the AF operation is performed after the predetermined starting point (after power-on). There is also a case where a manual operation is performed without being interrupted. In this case, the in-focus state is detected for all the areas in the shooting area, and the in-focus area frame is displayed in the focused area. The user can easily grasp which area is in focus as compared with the conventional manual operation in which the focus adjustment is performed while visually confirming the captured image.
