Description

  The present invention relates to a display device for an electronic camera in which the ISO sensitivity can be changed by changing the output gain of an image sensor.

  Conventionally, as described in JP-A-8-328077, a display device that displays ISO sensitivity information of a film is known. Further, JP-A-8-328077 discloses a method for manually changing the ISO sensitivity.

  Further, as described in JP-A-4-14233, the step number of exposure control values such as exposure correction amount, shutter speed or aperture value can be switched to 1/2 step or 1/3 step. The camera is open to the public.

  In recent years, electronic cameras using semiconductor image pickup devices such as CCD devices have become widespread, but the initial electronic cameras have insufficient image quality, and many silver halide cameras are equivalent to popular devices. However, with the development of semiconductor technology and electronic technology, an electronic camera capable of setting many photographing conditions such as a silver salt single-lens reflex camera has been manufactured.

  Among electronic cameras that can set a large number of shooting conditions, as described in Japanese Patent Application Laid-Open No. 11-331689 and Japanese Patent Application Laid-Open No. 2000-101891, a silver salt camera is obtained by changing the gain of the CCD. There is also an electronic camera that can manually set the ISO sensitivity of the silver salt film used in the above.

  In the case of a conventional silver salt camera, the ISO sensitivity value is determined by the film. The film sensitivity that is generally on sale is set to 1/3 step, such as ISO100, ISO125, ISO160, and ISO200.

  Further, as described in JP-A-8-328077, there is a camera that allows the user himself to change the ISO sensitivity by manual operation. It can be changed in 3 steps.

  As disclosed in Japanese Patent Application Laid-Open No. 4-14233, there is a camera that can switch the exposure control step to a 1/2 step or a 1/3 step, and the ISO sensitivity is changed. Even if the two-step step was set, the change in ISO sensitivity remained at the one-third step in accordance with the film.

  However, as described in Japanese Patent Application Laid-Open No. 11-331689 and Japanese Patent Application Laid-Open No. 2000-101891, in the case of an electronic camera that has become widespread in recent years, the gain of a CCD or the like corresponds to the ISO sensitivity of a silver salt film. To do. In other words, changing the ISO sensitivity only requires changing the gain of the CCD and does not depend on the film as in the case of a silver halide camera. For example, it is possible to change the ISO sensitivity in 1/2 step.

  However, the ISO sensitivity is only displayed in 1/3 step, and there is no ISO display in the case of 1/2 step.

Further, it is possible to calculate a 1/2 level ISO display. In this case, for example, ISO 200 → 283 → 400, which is a number that is unfamiliar to the user, and it is difficult to intuitively understand what the display represents, which causes problems such as confusion.

  Japanese Patent Application Laid-Open No. 11-331689 and Japanese Patent Application Laid-Open No. 2000-101891 do not describe means for solving the above problem.

  An object of the present invention is to solve the above-described problems. When the ISO sensitivity change step in the electronic camera is switched to a 1/2 step, an ISO display (1/2 step step) ( For example, when an ISO value intermediate between ISO 100 and ISO 200 is displayed, an electronic camera that can easily check the ISO sensitivity without being confused by the user is provided.

In order to achieve the above object, an electronic camera according to claim 1 is an image pickup device for picking up an image of a subject, display means for displaying information relating to photographing, ISO sensitivity setting means capable of setting ISO sensitivity, In an electronic camera having a gain adjusting means for adjusting a gain of an output from the imaging means according to the ISO sensitivity set by the ISO sensitivity setting means,
The display means includes a first display area for displaying an integer value of ISO sensitivity, and a second display area for performing a display for assisting the display displayed in the first display area. Accordingly, an ISO display that is an integral multiple of a single step is displayed in the first display area, and when an ISO display at a half step is performed (for example, when an ISO value intermediate between ISO 100 and ISO 200 is displayed), Since the auxiliary display indicating the 1/2 step is performed in the second display area, numbers that are not familiar to the user are not displayed, and the user is not confused.

  The electronic camera according to claim 2 is provided with control means for controlling the display means to display both or one of the first display area and the second display area. In the case of an integral multiple, ISO display is performed only on the first display area, and at the time of half-step ISO display (for example, when an ISO value intermediate between ISO 100 and ISO 200 is displayed), simultaneously with the first display area Since the auxiliary display indicating the 1/2 step is displayed in the second display area, a number that is not familiar to the user is not displayed, and the user is not confused.

  The electronic camera according to claim 3 further comprises resolution changing means for changing the resolution of the ISO value, and the first display area and the second display according to the resolution set by the resolution changing means. Control means for controlling to display both or one of the areas on the display means is provided. Therefore, for example, when the exposure control step is selected to be 1/3 step, the ISO value is displayed only in the first display area as in the past. When the exposure control step is selected to be a 1/2 step step, an ISO value that is an integral multiple of the 1 step step is displayed in the first display region, and a 1/2 step step is displayed in the second display region. Since the auxiliary display indicating the fact is displayed, numbers that are not familiar to the user are not displayed, and the user is not confused.

  As described above, according to the first invention of the present application, for example, when the exposure control step is selected to be 1/3 step, the ISO value is displayed only in the first display area as in the past. In addition, when the exposure control step is selected as a 1/2 step (for example, when an ISO value intermediate between ISO 100 and ISO 200 is displayed), the second display area indicates that it is a 1/2 step. Since the display is performed, numbers that are not familiar to the user are not displayed, and the user is not confused.

It is connected. The MPU 1 sequentially controls the above circuits in a predetermined order.

  Reference numeral 200 denotes a photographic lens, and reference numeral 12 denotes an AF (autofocus) drive circuit, which is constituted by a stepping motor, for example, and focuses the CCD 7 by changing the focus lens position in the photographic lens 200 under the control of the MPU 1.

  Reference numeral 13 denotes an aperture driving circuit, which is configured by, for example, an auto iris, and changes the aperture 2 by changing the MPU 1 to change the optical aperture value.

  A main mirror 4 is a main mirror for guiding a subject image formed by the photographing lens 200 to the pentaprism 3 and transmitting a part thereof to the focus detection sensor 15 through a sub-mirror 5 described later. The mirror drive circuit 14 is configured to be movable between a position where the subject image can be observed with the viewfinder and a retreat position where the subject image is retracted from the optical path of the subject light beam during photographing.

  Reference numeral 5 denotes a sub-mirror for reflecting the subject light transmitted through a part of the main mirror 4 and guiding the subject image to the focus detection sensor 15.

It is configured to be movable to a position for guiding light and to a retreat position for retracting from the optical path of the subject luminous flux during photographing.

  Reference numeral 14 denotes a mirror drive circuit, which includes, for example, a DC motor and a gear train, and drives the main mirror 4 and the sub mirror 5 under the control of the MPU 1.

  An optical member 3 is a penta roof prism that converts and reflects an object image guided by the main mirror 4 into an erect image.

  The subject luminous flux that has passed through the photographing lens 200 passes through the diaphragm 2, is reflected by the main mirror 4, is guided to the pentaprism 3, and the subject image is observed through the eyepiece window 111. Furthermore, it is guided to the photometric sensor 22. The light beam that has passed through the main mirror 4 is reflected by the sub-mirror 5 and re-imaged on the detection surface of the focus detection sensor 15 located at a position substantially equivalent to the CCD 7 surface.

  The optical image is converted into an electrical image signal and supplied to the focus detection circuit 16.

  The focus detection circuit 16 performs accumulation control and readout control of the focus detection sensor 15 according to the signal of the MPU 1 and outputs pixel information to the MPU 1.

  The MPU 1 performs a focus detection calculation by a known phase difference detection method based on the image signal of the subject image from the focus detection circuit 16, and the difference between the imaging surface formed by the photographic lens 200 and a predetermined imaging surface such as a film surface, That is, the defocus amount and the defocus direction are obtained.

  Then, the MPU 1 changes the focus lens position in the photographing lens 200 via the AF driving circuit 12 based on the calculated defocus amount and defocus direction, and drives it to the in-focus position.

  Reference numeral 6 denotes a mechanical shutter device. The front blade group 6a (not shown) that blocks the subject luminous flux during finder observation and retracts from the optical path of the subject luminous flux according to the release signal during imaging, and the optical path of the subject luminous flux during finder observation.

The mechanical shutter device 6 is controlled by a shutter drive circuit 17 that receives a command from the MPU 1.

  In the present embodiment, the case where both the front blade group 6a and the rear blade group 6b are provided is described. However, when exposure is started with only one shielding member, the light beam is retracted from the optical path of the subject luminous flux. However, it may be configured to return to a position where the optical path of the subject light flux is again blocked after the photographing is completed.

  Reference numeral 7 denotes a solid-state image sensor that captures a subject image formed by the photographing lens 200 and converts it into an electrical signal. As the solid-state imaging device, a CCD that is a known two-dimensional imaging device is used. There are various types of imaging devices such as a CCD type, a MOS type, and a CID type, and any type of imaging device may be employed. However, in this embodiment, there are two photoelectric conversion elements (photosensors). An interline CCD image pickup device that is arranged in a dimension and outputs signal charges accumulated in each sensor via a vertical transfer path and a horizontal transfer path is employed.

Reference numeral 8 denotes a clamp / CDS (correlated double sampling) circuit that performs basic analog processing before A / D conversion and can also change the clamp level.
Reference numeral 9 denotes an AGC (automatic gain adjusting device) which is a gain adjusting means, which can perform basic analog processing before A / D conversion and change the AGC basic level. The AGC basic level is set to a value corresponding to the ISO sensitivity setting described later. That is, when the ISO sensitivity value is changed, the basic level of AGC is changed.

  The CCD 7, the clamp / CDS circuit 8, the AGC 9, and the A / D converter 10 constitute an imaging means.

  Reference numeral 11 denotes a video signal processing circuit which takes charge of overall image processing by hardware such as gamma / knee processing, filter processing, and information composition processing for monitor display on the digitized image data of the CCD 7.

  The image data for monitor display from the video signal processing circuit 11 is displayed on the LCD monitor 120 via the LCD drive circuit 25.

  These functions are switched by exchanging data with the MPU 1, and the white balance information of the output signal of the CCD 7 can be output to the MPU 1 as needed. Based on this information, the MPU 1 performs white balance adjustment and gain adjustment. Do.

  Further, it is also possible to store image data in the buffer memory 27 through the memory controller 26 without doing anything in response to an instruction from the MPU 1. The video signal processing circuit 11 also has a function of performing compression processing such as JPEG.

  In the case of continuous shooting, image data is temporarily stored in the buffer memory 27. When processing time is required, unprocessed image data is read through the memory controller 26, and the video signal processing circuit 11 performs image processing and compression processing. It is configured to increase the continuous shooting speed. The number of continuous shots greatly depends on the size of the buffer memory 27.

  In the memory controller 26, unprocessed digital image data input from the video signal processing circuit 11 is stored in the buffer memory 27, and the processed digital image is stored in the memory 28, or conversely from the buffer memory 27 and the memory 28. Image data is output to the video signal processing circuit 11.

  Further, the memory controller 26 can store the video sent from the external interface 29 in the memory 28 and can output the image stored in the memory 28 from the external interface 29. The memory 28 can be removed from the camera body.

  Reference numeral 21 denotes a switch sense circuit which controls each part according to the operation state of each switch.

  Reference numeral 114a denotes a switch SW1 that is turned on by the first stroke of the release button 114. 114b is a switch SW2 that is turned on by the second stroke of the release button 114. When the switch SW2 is turned on, the release operation is started.

  A main electronic dial SW115, sub electronic dial 16, photographing mode selection SW117, AF mode selection SW118, photometry mode selection SW119, and dial resolution setting SW125 are connected, and the state of each SW is transmitted to the MPU1.

  When the dial resolution setting SW 125 is set to the “1/2” side, the amount of change per click when the main electronic dial SW 115 and the sub electronic dial 116 are rotated is set to 1/2 level. When it is set to the “1/3” side, the change amount per click when the main electronic dial SW 115 and the sub electronic dial 116 are rotated is set to 1/3 step.

  Parameters whose resolution is changed are shutter speed, aperture value, exposure correction amount, and ISO sensitivity.

  The MPU1, the switch sense circuit 21, and the dial resolution setting SW 125 constitute a resolution changing means.

  A photometric circuit 23 outputs an output from the photometric sensor 22 to the MPU 1 as a luminance signal for each area in the screen. The MPU 1 performs A / D conversion on the luminance signal and calculates the exposure for photographing.

  A liquid crystal display drive circuit 24 drives the external liquid crystal display device 140 and the in-finder liquid crystal display device 30 in accordance with the display content command of the MPU 1. Further, the liquid crystal display driving circuit 24 can put a specific segment in a blinking display state according to an instruction from the MPU 1.

  The MPU 1, the liquid crystal display driving circuit 24, and the external liquid crystal display device 140 constitute display means.

  A power source 31 supplies power necessary for each IC (integrated circuit) and drive system.

  Next, the ISO sensitivity setting method will be described with reference to FIGS.

  In step S100 in FIG. 5, it is determined whether both the AF mode SW 118 and the AE mode SW 119 are turned on. If it is determined that the power has been turned on, the process proceeds to step S101 to enter the ISO setting mode. At this time, the external liquid crystal display device 140 displays as shown in FIG. 6 or FIG.

  When the resolution setting SW is set to the “1/2” side, a display as shown in FIG. 6 is shown. When the resolution setting SW is set to the “1/3” side, a display as shown in FIG. 7 is shown. Then, when an operation described in detail later is performed, the display changes.

  In step S102, it is determined whether or not the main electronic dial 115 has been input. When input, the process proceeds to step S103. If not, the process proceeds to step S106.

  In step S103, the state of the resolution setting SW 125 is determined. When it is set to “1/2”, the process proceeds to step S104, and when it is set to “1/3”, the process proceeds to step S105.

  In step S104, the display on the external liquid crystal display device 140 is switched in accordance with the input from the main electronic dial 115.

  The display switching in step S140 will be described with reference to FIG.

  FIG. 6A shows an initial state when the ISO change mode is set. 6A shows that the current ISO setting value is ISO200.

  In step S104, for example, when the main electronic dial 115 is rotated by one click in the clockwise direction from the initial state, the ISO sensitivity increases by ½ step, and when rotated in the counterclockwise direction, the ISO sensitivity decreases by ½ step. Change the display as you go.

  FIG. 6B shows a state in which it is rotated clockwise by one click from the initial state (FIG. 6A) (a state in which the ISO has changed by 1/2 step).

In FIG. 6B, “+0.5” is displayed in the second display area 140d. This indicates that it has increased by a half step with respect to ISO 200 (ISO value between ISO 200 and ISO 400).
Further, when rotated by one click clockwise, 140c is displayed as 400, and 140d is displayed as 0. This state indicates that the ISO 400 has been set. That is, it is changed from the initial state of FIG. 6A by one stage (= the main electronic dial 115 is two clicks clockwise).

  Further, when rotated clockwise by one click, the display of 140c remains 400 and 140d displays +0.5. This state shows that it has increased by 1/2 with respect to ISO400. (ISO value intermediate between ISO 400 and ISO 800) In other words, it is changed by 1.5 steps (= main electronic dial 115 is 3 clicks clockwise) from the initial state of FIG. 6A.

  When the main electronic dial 115 is rotated in the counterclockwise direction, the main electronic dial 115 decreases in half steps. For example, when FIG. 6-d is in the initial state, the state changes from FIG. 6-c to FIG. 6-b to FIG. 6-a according to the rotation of the dial.

  In this way, the display of the first display area 140c changes one step at a time, and the half of the display is expressed using the second display area 140d. It is possible to confirm the ISO value.

Therefore, even if an attempt was made to express 1/2 ISO of the 140c display area as in the conventional case, the sensitivity of the silver salt film could not be expressed because there was no 1/2 stage. Although it is possible to calculate 1/2 level, the ISO value in this case is ISO200 → 283 → 400 → 565, which is a number that is unfamiliar to the user, and the meaning of the number is immediately The problem of not being able to understand occurs.

  Returning to FIG. 5, when the resolution setting SW is set to 1/3 in step S103, the process proceeds to step S105.

  In step S105, the display on the external liquid crystal display device 140 is switched in accordance with the input from the main electronic dial 115.

  The display switching in step S105 will be described with reference to FIG.

  FIG. 7A shows an initial state when the ISO change mode is set. FIG. 7A shows that the current ISO setting value is ISO200.

  From this state, every time the main electronic dial 115 is rotated, for example, by one click clockwise, 200 → 250 (FIG. 7B) → 320 (FIG. 7C) → 400 (FIG. 7D). It will increase by 1/3 step.

  Further, when the rotation operation is performed in the counterclockwise direction, the number decreases by 1/3 as 1600 → 1250 → 1000 → 800.

  In the case of the 1/3 step, since there is a display from the time of the silver halide film, it can be expressed only by the display of the first display area 140c, and the user can confirm the ISO value without being confused.

  Returning to FIG. 5, in step S106, it is determined whether or not the AF mode SW118 / AE mode SW119 is turned off. If not, the process proceeds to step S102, and the operations already described are repeated to turn off. When it is determined that the display has been made, the ISO setting mode is terminated and the display state described with reference to FIG. 3 is obtained.
