The reflecting mirror 205 is not arranged at the third position when arranged in the position. That is, the half mirror 201 and the reflection mirror 205 are moved together to move to the first position, the third position, the second position, and the fourth position, respectively.

  When the half mirror 201 is arranged at the first position, the luminous flux of the subject incident through the photographing lens 101 is guided to the half mirror 201, and the luminous flux of the light reflected by the half mirror 201 is the focusing screen. The light that has been guided to the photographer's eyes through 202, the pentaprism 203, and the eyepiece lens 204, and transmitted through the half mirror 201 is guided to the distance measuring sensor 206 through the reflection mirror 205. The half mirror 201, the focusing screen 202, the pentaprism 203, and the eyepiece 204 function as an optical viewfinder.

  Here, the first position is a position where the half mirror 201 is disposed obliquely with respect to the optical axis in the photographing optical path (position shown in FIG. 1), and the second position is a photograph of the half mirror 201. This is the position to be retracted out of the optical path. The third position is a position of the reflecting mirror 205 that guides the light transmitted by the half mirror 201 to the distance measuring sensor 206 when the half mirror 201 is disposed at the first position ( The position shown in FIG. 1 and the fourth position are positions where the reflecting mirror 205 is retracted out of the photographing optical path.

  Here, the focusing screen 202 is a mat for forming an image of the light flux of the subject. The focusing screen 202 has a plurality of AF frames engraved and the focused AF frame emits light. . For example, a liquid crystal may be provided on the focusing screen 202 so that the AF frame emits light, and the focused AF frame may emit light. Here, it is assumed that the liquid crystal can emit a plurality of colors. The AF frame light emission is performed by the AF frame light emission drive unit 209 in accordance with a control signal from the CPU 215. Here, the color includes not only colors such as red and blue, but also black and white.

FIG. 2 shows an example of a subject image that can be seen when the photographer looks into the eyepiece lens 204.
FIG. 2A shows a state of a subject image that can be seen when AF processing is not performed, and FIG. 2B shows a state of a subject image that can be seen when AF processing is performed. It is.

  Referring to FIG. 2A, since the AF process is not performed, it can be seen that a plurality of AF frames 11 stamped on the focusing screen 202 are simply displayed. When the AF process is performed, FIG. As shown in B), it can be seen that the focused AF frame 11 emits light. Here, for convenience, it is assumed that the issued AF frame 11 is indicated by diagonal lines.

  The distance measuring sensor 206 includes a pair of light receiving elements, and an image of light transmitted through the half mirror 201 and incident through the reflecting mirror 205 is formed by the pair of light receiving elements of the distance measuring sensor 206 to measure the distance. The circuit 207 detects the amount of deviation of the image formed by the pair of light receiving elements of the distance measuring sensor 206 by the phase difference method, and measures the distance to the subject.

  Here, the distance measuring sensor 206 includes a pair of light receiving elements that form an image of the subject in each AF frame 11 stamped by the focusing screen 202, and the distance measuring circuit 207 includes each AF frame 11. The amount of deviation of the image formed by the pair of light receiving elements that form the image of the subject within the AF frame 11 is detected, and the distance to the subject (subject distance) within each AF frame 11 is measured. The measured subject distance of each AF frame 11 is sent to the CPU 215.

  A shutter 210 is disposed behind the half mirror 201 and is driven by a drive circuit (not shown). This drive circuit drives the shutter 210 in accordance with a control signal from the CPU 215. A CCD 211 is disposed behind the shutter 210.

  When the half mirror 201 and the reflection mirror 205 are arranged at the second position and the fourth position, respectively, the luminous flux of the subject incident through the photographing lens 101 is guided to the shutter 210, and the shutter 210 is In the open state, light is incident through the taking lens 101 and the shutter 210 and the light of the subject is guided to the CCD 211.

  The CCD 211 has a Bayer color filter and is driven by a driver 212 to photoelectrically convert the intensity of light of each RGB value of the subject image and output it to the unit circuit 214 as an imaging signal. The operation timing of the driver 212 and the unit circuit 214 is controlled by the CPU 215 via the TG 213. Here, the CCD is exemplified as the image pickup device, but it may be a CMOS or the like, and the color filter is not limited to the color filter of the Bayer arrangement, and no color filter may be provided. Good.

  A TG 213 is connected to the unit circuit 214, a CDS (Correlated Double Sampling) circuit that holds the imaged signal output from the CCD 211 by correlated double sampling, and an AGC that performs automatic gain adjustment of the imaged signal after the sampling. An (Automatic Gain Control) circuit and an A / D converter that converts the analog image pickup signal after the automatic gain adjustment into a digital signal, the image pickup signal output from the CCD 211 passes through the unit circuit 214 as a digital signal. Sent to the CPU 215.

  The CPU 215 performs image processing (for example, γ correction processing, white balance processing, generation of luminance color difference signal (YUV data)) on the image data sent from the imaging processing, AF processing, AE processing, and unit circuit of the CCD 211. In addition to performing a process for storing captured image data in the buffer memory (DRAM 218) and recording the image data stored in the buffer memory in the flash memory 219, each part of the digital single-lens reflex camera 1 is provided. It is a one-chip microcomputer to control. The CPU 215 includes a clock circuit and also has a function as a timer.

  Further, the CPU 215 has a function of controlling the light emission of the focused AF frame 11 and a function of controlling the display of the monitor 220.

The key input unit 216 includes a plurality of operation keys such as a shutter button that can be half-pressed and fully pressed, a mode switching key, a cross key, and a SET key, and outputs an operation signal corresponding to the photographer's key operation to the CPU 215.
The memory 217 stores a control program and necessary data necessary for the CPU 215 to control each unit of the digital single-lens reflex camera 1, and the CPU 215 operates according to the program. The memory 217 is a rewritable nonvolatile memory.

The DRAM 218 is used as a buffer memory for temporarily storing image data sent to the CPU 215 after being imaged by the CCD 211 and also as a working memory for the CPU 215.
The flash memory 219 is a recording medium that stores compressed image data.

  The monitor 220 includes a color LCD and its drive circuit, and displays the subject imaged by the CCD 211 as a through image when in a shooting standby state, and displays a recorded image read from the flash memory 219 during reproduction of the recorded image. Display. Note that the screen of the monitor 220 is larger than the screen seen from the optical viewfinder.

B. Operation of Digital SLR Camera 1 The operation of the digital single lens reflex camera 1 in the embodiment will be described with reference to the flowchart of FIG.

  When the photographing mode is set by the user's operation of the mode switching key, the CPU 215 sends a control signal to the mirror driving unit 208, thereby bringing the half mirror 201 into the first position and the reflecting mirror 205 into the third position. Arrange (step S1). Thereby, the user can see the subject through the eyepiece lens 204 when the light of the subject incident through the photographing lens 101 is guided to the eyepiece lens 204, and the AF frame overlaps the subject. 11 is displayed.

  Next, the CPU 215 determines whether or not the shutter button is half-pressed by the user (step S2). This determination is made based on whether or not an operation signal corresponding to the half-press operation of the shutter button is sent from the key input unit 216.

  If it is determined in step S2 that the shutter button is not half-pressed, the process stays in step S2, and if it is determined that the shutter button is half-pressed, the CPU 215 starts driving the monitor 220 (display is turned on), and Is displayed. (Step S3). At this time, portions other than the AF frame are darkened. That is, the display brightness other than the AF frame is lower than the display brightness of the AF frame.

  Further, the AF frame displayed on the monitor 220 is displayed at the same position as the AF frame visible on the optical viewfinder. That is, if image data is captured by the CCD 211 and the captured image data is displayed on the monitor 220, the subject within the AF frame displayed on the optical viewfinder and the AF frame displayed on the monitor 220 are displayed. An AF frame is displayed on the monitor 220 so that the subject inside is the same. In other words, the position of the AF frame 11 visible on the optical viewfinder and the position of the AF frame displayed on the monitor 220 are the same position with respect to the angle of view of the image data to be captured.

  Note that when the viewfinder field ratio is 100%, the angle of view of the image viewed from the optical viewfinder and the angle of view of the image displayed on the monitor 220 are the same. Therefore, the position of each AF frame on the optical viewfinder and the monitor 220 are the same. The position of the upper AF frame is similar.

  Next, the CPU 215 performs AF processing and AE processing (step S4). Here, the AF process is performed based on the subject position of each AF frame 11 measured by the distance measuring circuit 207. Here, the AF processing may be performed so that the AF frame 11 with the shortest subject distance is in focus, or the AF processing is performed so that the AF frame 11 designated by the user is in focus. You may do it. That is, the focus lens 101A is moved based on the subject distance of the AF frame 11 that is the target of AF processing. Here, even if the AF frame 11 is not AF processed so as to be in focus, if it is within the depth of field, the AF frame 11 is in focus.

  In the AE process, an exposure condition (for example, aperture value, shutter speed, gain, etc.) is calculated based on the light intensity measured by a photometric sensor (not shown), and the calculated exposure condition is set.

  Next, the CPU 215 transmits a control signal to the AF frame light emission drive unit 209 to cause the AF frame 11 of the focused focusing screen 202 to emit light (step S5). Here, it is assumed that a subject image as shown in FIG. 2B is visible from the optical viewfinder. In this way, by emitting the focused AF frame 11 (focused region), it is possible to identify the AF frame 11 that is not focused and the focused AF frame 11. Note that the focused AF frame 11 only needs to be identified, and may be identified by other methods.

Next, the CPU 215 identifies and displays the AF frame (focused area) on the monitor 220 corresponding to the focused AF frame 11 (step S6).
FIG. 4 shows an example of the state of the AF frame 12 identified and displayed on the monitor 220.
Here, for convenience, the AF frame 12 on the monitor 220 corresponding to the focused AF frame 11 is identified and displayed by hatching. However, the AF frame 12 is identified and displayed by the color, the thickness of the AF frame 12, or the like. It may be.
Here, when FIG. 2B is compared with FIG. 4, the position of the AF frame 11 emitting light on the optical viewfinder and the AF frame 12 identified and displayed on the monitor 220 are in the same position. Recognize. As a result, the user can easily visually recognize which part is in focus by looking at the monitor 220.
At this time, the display brightness of the AF frame 12 corresponding to the AF frame 11 that is not in focus may be made lower than the display brightness of the AF frame 12 corresponding to the focused AF frame 11. In this case, the display brightness of the AF frame 12 corresponding to the AF frame 11 that is not in focus may be the same as the display brightness of the area other than the AF frame 12, or the display brightness of the area other than the AF frame 12. It may be higher.

  Next, the CPU 215 determines whether or not the user has fully pressed the shutter button (step S7). This determination is made based on whether or not an operation signal corresponding to the full pressing operation of the shutter button is sent from the key input unit 216.

  If it is determined in step S7 that the shutter button is not fully pressed, the process stays in step S7 until it is fully pressed. If it is determined that the shutter button is fully pressed, the CPU 215 turns off the monitor display (step S8). That is, the display is terminated by stopping the driving of the monitor 220.

Next, the CPU 215 sends a control signal to the mirror driving unit 208 to place the half mirror 201 at the second position and the reflecting mirror 205 at the fourth position (step S9). As a result, the half mirror 201 and the reflection mirror 205 are retracted out of the photographing optical path.
Next, the CPU 215 performs still image shooting (step S10). That is, image processing is performed on the image data that is imaged by the CCD 211 under the exposure conditions (aperture value, shutter speed) set in step S4 and automatically gain adjusted by the AGC of the unit circuit 214 according to the gain value set in step S4. And stored in the buffer memory (DRAM 218).
Next, the CPU 215 compresses the captured image data (for example, JPEG compression) and records it in the flash memory 219 (step S11).

  As described above, in the embodiment, the AF frame 11 focused on the optical viewfinder is displayed by light emission, and the AF frame 12 displayed on the monitor 220 at the same position as the AF frame 11 visible on the optical viewfinder. Among them, since the AF frame 12 corresponding to the focused AF frame 11 is identified and displayed, the user can visually recognize the focused AF frame easily and clearly by looking away from the optical viewfinder and looking at the monitor 220. This makes it easier to understand the in-focus area.

  In addition, since the screen of the monitor 220 is larger than that of the optical viewfinder, the focused AF frame can be easily recognized by looking at the monitor 220.

  Further, the drive of the monitor 220 is started after the shutter button is half-pressed (display is turned on), and the drive of the monitor 220 is stopped (display is turned off) after the shutter button is fully pressed, so that power consumption can be suppressed. At the same time, it is possible to suppress the display (brightness) of the monitor 220 from getting in the way when looking into the optical viewfinder.

  Further, since the area other than the AF frame 12 is displayed on the monitor 220 so as to be darker than the brightness of the AF frame 12, the power consumption can be suppressed and the screen of the monitor 220 is dazzling, and the optical viewfinder and the monitor 220 are displayed. It is possible to prevent the harmful effect that it is difficult to see. Further, since the AF frame 12 is brighter than the surroundings, the AF frame is easy to see.

[Modification]
C. The above-described embodiment can be modified as follows.

(01) In the above embodiment, the AF frame 12 on the monitor 220 corresponding to the focused AF frame 11 is simply identified and displayed. However, the AF frame 12 is identified and displayed according to the degree of focus. It may be changed.
The AF frame 12 corresponding to the AF frame 11 having a higher focus evaluation value indicating the degree of focus may be displayed brighter or the color of the AF frame 12 may be displayed darker. The AF frames 12 may be displayed by ranking in descending order. For example, the AF frames 11 are ranked so that the AF frame 11 with the highest focus evaluation value is number 1 and the AF frame 11 with the next highest focus evaluation value is number 2, and the AF frame 11 corresponds to the AF frame 11. The order may be displayed on the AF frame 12 on the monitor 220, may be ranked by changing the color, or may be ranked by brightness, color intensity, or the like. Also good.
The focus evaluation value sets the focus evaluation value of the AF frame 11 that is the target of the AF processing to be the highest, and uses the subject distance of the AF frame 11 that is the target of the AF processing as a reference distance. The focus evaluation value is increased for the AF frame 11 whose subject distance is closer to the reference distance.
Thus, it is possible to easily recognize in an easy-to-understand manner which area is in focus, and it is also possible to easily recognize in an easy-to-understand manner how much the area is in focus.

  (02) In the above embodiment, the drive of the monitor 220 is started (display is turned on) after half-pressing the shutter button. However, the drive of the monitor 220 may be started after the AF processing is completed. Thereby, power consumption can be further suppressed.

(03) In the above embodiment, the monitor 220 displays the AF frames 12 corresponding to the plurality of AF frames 11 visible on the optical viewfinder regardless of the focused AF frame 11. Only the AF frame 12 corresponding to the focused AF frame 11 may be displayed. That is, the AF frame 12 corresponding to the AF frame 11 that is not in focus is not displayed.
Further, only the focused AF frame 11 may be displayed on the optical viewfinder. In this case, the AF frame 11 focused by the liquid crystal provided on the focusing screen 202 is displayed without imprinting the AF frame 11 on the focusing screen 202.
Thereby, the in-focus area can be visually recognized easily and easily, and the intelligibility of the in-focus area can be improved.

(04) In the above embodiment, the through image may be captured by the CCD 211, and the captured through image may be displayed on the monitor 220. That is, both the through image and the AF frame 12 are displayed on the monitor 220. In this case, the subject image and the AF frame are displayed on both the optical viewfinder and the monitor 220, but the screen of the monitor 220 is larger than the optical viewfinder. 12 can be easily visually recognized.
In this case, the contrast method is employed in which the light that has passed through the half mirror 201 is directly captured by the CCD 211 without the reflection mirror 205, and the AF processing is performed based on the image data captured by the CCD 211.

(05) In the above embodiment, the finder in the claims is described as an optical finder. However, an electronic finder or a liquid crystal monitor may be used instead of the optical finder, and the information that indicates the subject image and the in-focus area is essential. As long as it can display.
In the case of the electronic viewfinder, the through image may be displayed on the CCD 211, the through image and the AF frame 11 may be displayed on the electronic viewfinder, and only the AF frame 12 may be displayed on the monitor 220, or the electronic viewfinder and the monitor 220 may be displayed. In both cases, a through image and an AF frame may be displayed.
Similarly, in the above embodiment, the display means in the claims has been described as the monitor 220. However, instead of the monitor 220, an optical finder or an electronic finder may be used. Any display that can display the focal area is acceptable.

(06) In the above modification examples (04) and (05), when the CCD 211 captures a through image and performs the AF process by the contrast method based on the captured image data, the AF frame that is the target of the AF process The focus lens 101A is moved to the lens position (focusing lens position) where the high frequency component of the image data 11 is the highest, thereby focusing.
Here, as in the modification (01), the identification display of the AF frame 12 may be changed according to the degree of focus. The focus evaluation value in this case is determined based on the high-frequency component of each AF frame 11 when the focus lens 101A is at the focus lens position. That is, the focus evaluation value increases as the high frequency component increases.

(07) In the above embodiment, the AF frame 12 is identified and displayed on the monitor 220 to indicate the focused area. However, the AF frame 12 is not displayed and the focused area is displayed. May be identified and displayed by other methods. For example, the in-focus area may be filled and displayed, the image of the subject in the in-focus area may be enlarged, or the in-focus area may be indicated by text or the like.
Even when the finder is an electronic finder, the focus area may be identified and displayed by another method without displaying the AF frame 11.

  (08) In the above embodiment, the subject image and the AF frame 11 are displayed on the finder, and the monitor 220 displays the AF frame 12 without displaying the subject image. The aspect may be reversed. That is, the AF frame 12 is displayed on the finder without displaying the subject image, and the subject image and the AF frame 11 are displayed on the monitor 220. In this case, it is necessary to move the half mirror 201 to the second position and the reflection mirror 205 to the fourth position, respectively.

  (09) In the above embodiment, if it is determined in step S7 in FIG. 3 that the shutter button is not fully depressed, the shutter button remains in step S7 until it is fully depressed. If it is determined that it is not fully pressed, the process may return to step S4. That is, the AE and AF processes may be continuously performed, and the AF frame 11 may be emitted in step S5 and the AF frame 12 may be identified and displayed in step S6.

  (10) In the above embodiment, the digital single-lens reflex camera 1 has been described. However, a digital camera such as a compact digital camera that cannot exchange lenses may be used.

  (11) The above embodiment may be an embodiment in which the above modifications (01) to (10) are arbitrarily combined.

(12) The above embodiments of the present invention are merely examples as the best embodiments, and are described in order to better understand the principle and structure of the present invention. And is not intended to limit the scope of the appended claims.
Therefore, it should be understood that all the various variations and modifications that can be made to the above-described embodiments of the present invention are included in the scope of the present invention and protected by the appended claims.
