Description

  The present invention relates to an imaging apparatus, and more particularly to an imaging apparatus provided with a small display device used for composition adjustment at the time of shooting.

  Today, imaging devices represented by digital cameras and digital video cameras are in widespread use. Many of these imaging devices include a color image sensor, which converts a still image or a moving image captured by the image sensor into a digital image signal, and records and holds it on a recording medium such as a flash memory or a magnetic tape device. In addition, the recorded data can be taken into an image processing device such as a personal computer, and can be freely viewed and processed. .

  By the way, such an imaging apparatus is provided with a small display device, except for some low-priced products, and it is possible to perform composition adjustment at the time of photographing and confirmation of a photographed image using this display device. For example, in the case of a digital camera equipped with a small (1.5 or 2 inch) liquid crystal display on the camera body, a live view image is displayed on the liquid crystal display and the image display is used instead of the viewfinder. Thus, composition adjustment can be performed.

  However, in an imaging apparatus including a small display device as described above, display parameters (such as a luminance level, a contrast level, and a color level) of the display device are exclusively suitable for appearance and suitable for small image display. For example, if you try to manually adjust the exposure or white balance while looking at the displayed image, the difference from the actual subject image is too large. There was a problem of going to.

  The reason for setting the emphasis on appearance is as follows. That is, in the case of a small display device, even if it is set to a display parameter with good reproducibility that is close to the actually visible subject image due to its small display area, the gradation and color of the human eye are This is because it is difficult to discriminate the difference, and the image quality tends to be perceived as poor, and the user cannot appeal to the user for good image quality unless the gradation and color development are intentionally emphasized. Therefore, in many imaging equipment manufacturers, in order to ensure the superiority of their products in the market and to withstand the image quality comparison of display devices at stores, etc., gradation and color development are intentional. This is because it must be emphasized and set to emphasize the appearance.

  Therefore, the present invention is capable of sufficiently withstanding the image quality comparison of display devices in stores or the like in an imaging apparatus equipped with a small display device, and has good reproducibility close to an actually visible subject image. An object of the present invention is to provide an imaging apparatus that can display an image, and can appropriately perform manual adjustments such as exposure and white balance by using an image display with good reproducibility.

The present invention provides an image pickup apparatus including an image sensor that generates an image signal of a subject and a display device that displays the image signal, and includes a parameter switching unit that switches an operation parameter of the display device according to a shooting mode. The parameter switching means can be switched at least between a first parameter that emphasizes the appearance of image display by the display device based on the image signal generated by the image sensor and a second parameter that emphasizes the reproducibility of the image display. It is comprised by these.
In a preferred aspect of the present invention, the parameter switching unit switches to the second parameter in a manual shooting mode in which shooting conditions of the imaging apparatus are manually adjusted. In this aspect, when manual adjustments such as exposure and white balance are performed, a highly reproducible image suitable for the confirmation is displayed on the display device.
In a preferred aspect of the present invention, the parameter switching means switches to the first parameter in a shooting mode with flash emission, and sets the second parameter in a shooting mode without flash emission. It is characterized by switching.

According to the present invention, the parameter for changing the image quality of the image displayed on the display device is switched to at least one of emphasis on appearance and reproducibility. Therefore, if the emphasis is on appearance, it can sufficiently withstand image quality comparison at the display device store, etc., and if emphasis is placed on reproducibility, display an image that is close to the subject image that is actually visible, Manual adjustments such as exposure and white balance can be performed properly.
Alternatively, according to a preferred aspect, when performing manual adjustment such as exposure and white balance, an image with good reproducibility suitable for the confirmation is displayed on the display device. Therefore, it is possible to manually adjust the exposure, white balance, etc. while checking the reproducible image, and avoid inappropriate adjustment.

And an RGB matrix unit 34k for generating a B signal.

  Here, the illustrated color process circuit 34 is not particularly limited, but is an IC chip mounted component, and some of the operation parameters inside the circuit can be set from the outside. For example, “Va”, “Vb”, and “Vc” shown in the figure are external parameter setting values, which are a luminance level setting value (Va), a contrast level setting value (Vb), and a color level setting value (Vc), respectively. ).

  The parameter setting circuit 35 shown in FIG. 4 is a circuit for generating these setting values (Va to Vc). That is, the parameter setting circuit 35 includes an RC integration circuit for each set value, and the first integration circuit including the fixed resistor 35a and the capacitor 35b is a period of the luminance level control periodic signal Da output from the CPU 40.

The voltage is output to the color process circuit 34 as a contrast level setting value (Vb). Further, similarly, the third integrating circuit composed of the fixed resistor 35e and the capacitor 35f accumulates an integrated voltage in the capacitor 35f according to the period length Tc of the color level control periodic signal Dc output from the CPU 40, and integrates the integrated voltage. The voltage is output to the color process circuit 34 as a color level setting value (Vc).

  According to the parameter setting circuit 35 having such a configuration, by changing the cycle length of each control periodic signal output from the CPU 40, a large voltage close to the amplitude (+ 3V in the figure) of each control periodic signal can be obtained. The integration voltage can be variably set in a stepless manner up to a small voltage equivalent to 0 V, and the brightness level, contrast level, and color level parameters of the color process circuit 34 can be individually controlled.

Next, the operation will be described.
FIG. 5 is a flowchart showing an overall outline of a control program executed by the control system 22. This program starts executing when the power is turned on (when the power switch 9 in FIG. 1 is turned on). First, initial setting such as operation check is performed in step S1, and then REC / PLAY is performed in step S2. The operation of determining the set operation mode (recording mode and reproduction mode) of the key 14 and executing a branching process (recording mode process in step S3 and reproduction mode process in step S4) according to the determination result is repeated. Although there are other operation modes such as a system setting mode, they are omitted here for simplicity of explanation.

FIG. 6 is a flowchart of the recording mode processing program.
When this flowchart is started, first, in step S11, a CCD image, that is, an image signal from the image generation system 16 is read. Next, in step S12, it is determined whether or not the shooting mode is the manual shooting mode.

  Here, the manual photographing mode is a mode in which exposure, white balance, and the like can be manually adjusted according to the user's preference. If the manual shooting mode is set, the determination result in step S12 is “YES”. If not, that is, if the automatic shooting mode is set to automatically set exposure, white balance, etc., the process proceeds to step S12. The determination result is “NO”. Next, in accordance with the determination result in step S12, a setting value regarding how the through image displayed on the liquid crystal display 43 is seen is changed. Specifically, when the auto shooting mode is set, in step S13, the display condition (the above-mentioned “through image”) of the screen of the liquid crystal display 43 displaying the through image (hereinafter referred to as “monitor screen”) is displayed. In the case of the manual shooting mode, the display condition of the monitor screen is set to “emphasis on reproducibility” in step S14.

  The above terms (emphasis on appearance and reproducibility) are defined as follows. First, emphasis on appearance is to avoid poor visual image quality (brightness level, contrast level, color level, etc.) caused by the small display area when an image is displayed on the liquid crystal display 43 having a small display area. Therefore, it means intentionally enhancing the brightness level, contrast level, color level, etc. In short, it means that necessary processing is performed so as to obtain a good image that can withstand comparison with other digital cameras. . For this purpose, for example, a setting that is recognized as a good image quality by many subjects may be found by trial and error, and set as a setting value of “appearance-oriented”. On the other hand, reproducibility emphasis refers to an object image that is actually visible, for example, an image that is closest to an object image that is visible through a direct-view object image or an optical viewfinder. A setting that can be recognized as an image quality close to the actual subject image as seen from the subject may be found by trial and error and set as a setting value of “emphasis on reproducibility”.

  When the display condition of the monitor screen is set in this way, the image signal read from the image generation system 16 is displayed on the image display system 19 in step S15. This display image is a through image, and the display condition is “appearance-oriented” in the auto shooting mode, and “reproducibility priority” in the manual shooting mode. The user adjusts the composition while viewing the through image, or adjusts the exposure, white balance, and the like using the through image that emphasizes “reproducibility” when the manual shooting mode is set.

  Thereafter, when half-pressing of the shutter key 5 is detected in step S16, the aperture of the optical system 28 is fixed at the exposure according to the brightness of the subject at that time in step S17 (in the case of the auto photographing mode). In the case of manual shooting mode, the user setting value is fixed.) When full depression of the shutter key 5 is detected in step S18, the CCD image at that time is compressed and recorded (captured) in the flash memory 39 in step S19. .

  As described above, in step S15, the through image displayed on the liquid crystal display 43 is “focus on appearance” in the auto shooting mode and “emphasis on reproducibility” in the manual shooting mode. The setting is performed as follows.

  First, the CPU 40 executes either step S13 or step S14 according to the determination result of step S12. When step S13 is executed, the CPU 40 sets the values of the period lengths (Ta to Tc) of the various periodic signals for control (Da to Dc) to be given to the parameter setting circuit 35 to “value-oriented” (described in the gist of the invention). Corresponding to the first parameter). Alternatively, when step S14 is executed, the CPU 40 sets the “reproducibility-oriented” value (the value of the invention) to the set value of the cycle lengths (Ta to Tc) of the various control periodic signals (Da to Dc) to be given to the parameter setting circuit 35. (Corresponding to the second parameter described in the abstract).

  The parameter setting circuit 35 receives various control periodic signals (Da to Dc) set with emphasis on appearance or reproducibility, and has a luminance level setting value having a potential corresponding to the period length (Ta to Tc) of each signal ( Va), a contrast level setting value (Vb), and a color level setting value (Vc) are generated, and each part of the color process circuit 34, that is, a pedestal clamp brightness adjustment unit 34d, a contrast adjustment unit 34c, and a color control unit 34f. The image quality of the YUV signal (R / G / B image signal) taken out from the color process circuit 34 is set to “priority in appearance” or “emphasis on reproducibility”.

  Therefore, according to the above-described embodiment, in the case of the auto shooting mode, the through image displayed on the liquid crystal display 43 can be “importantly looking”, regardless of the small display area. Displaying through-images with good visual quality to ensure superiority in the market, providing technology that can withstand image quality comparison with other products in stores, etc., and manual shooting In the case of the mode, the through image displayed on the liquid crystal display 43 can be made “emphasizing reproducibility”, so that it is possible to accurately adjust the exposure and white balance, which is a unique effect that does not exist in the prior art. Obtainable. Of course, the setting of the parameters is “emphasis on appearance” and “emphasis on reproducibility”, but the present invention is not limited to this, and a plurality of set parameters (such as the third parameter, the fourth parameter, etc.) may be switched. Needless to say.

In addition, for example, the determination result of whether or not the flash photography is performed is made in the determination in step S12. If the flash photography (strobe light emission), “YES” is determined. In step S14, the monitor screen is set to a bright setting of “focus on appearance” and the flash photography is performed. If there is no (no flash emission), “NO” is set, and the monitor screen is set to “emphasis on reproducibility” that is close to the actual subject image in step S13. By doing this, it was difficult to determine the composition because it was dark and it was difficult to see the subject when shooting with a normal flash, but it was difficult to determine the composition by setting “Focus on the appearance” to determine the composition. Can be easily done.
Further, in the above embodiment, the display condition of the monitor screen is set as “importance of appearance” in step S13 and “emphasis of reproducibility” in step S14, but when the through display in step S15 is set, the user Now, it is possible to improve the usability by displaying the current display conditions superimposed on the through display so that the current display conditions are superimposed on the through display so that the display conditions can be seen at a glance.

In addition, this invention is not limited to said embodiment, Of course, various modifications are included in the range of the technical thought.
For example, in the setting mode, the quality of the through image (emphasis on appearance / emphasis on reproducibility) may be freely changed.
FIG. 7A is a diagram showing a main part flowchart of the setting mode processing program. In this setting mode processing, various setting values according to the specifications of the digital camera 1 such as various setting value changes relating to the operation of the digital camera 1, such as the definition of the recorded image, on / off of autofocus, and the shooting time of moving image shooting. Although the value is changed, this modification is particularly characterized in that it has a routine for changing a set value related to the appearance of the through image displayed on the liquid crystal display 43 as shown in step S6 in the figure.

  That is, in this step S6, first, the setting change of the display condition (the above-mentioned “setting value relating to the appearance of the through image”) of the screen (monitor screen) of the liquid crystal display 43 displaying the through image is performed. It is determined whether or not to perform (step S6a). This determination may be made, for example, by detecting a pressing operation of the menu key 8 or the like. In this case, if the pressing operation of the menu key 8 or the like is not detected (determination result is “NO”), other setting processing is performed, but if the pressing operation of the menu key 8 or the like is detected (determination result is “YES”). ), A predetermined setting screen is displayed on the liquid crystal display 43 (step S6b), the user selection is awaited, and the display condition selected by the user is held (step S6c). Of course, a plurality of display conditions selected by the user are possible and can be held.

  FIG. 7B is an example of the setting screen 50 displayed on the liquid crystal display 43 in step S6b. The setting screen 50 has a display area 50a for a predetermined operation guidance character string ("Please select the display condition of the monitor screen" in the figure) and two selectable objects 50b and 50c. Each of the objects 50b and 50c is given a title character string that appropriately represents the display conditions that can be set. Specifically, the first object 50b has a title character string of “emphasis on appearance”. The second object 50c is given a title character string “emphasis on reproducibility”.

  The user selects the first object 50b (touch operation on the touch panel 44) when he / she wants to emphasize the appearance of the through image displayed on the liquid crystal display 43, while he / she wants to emphasize the reproducibility. Selects the second object 50c. In response to the selection operation of the first object 50b, the CPU 40 looks at the set values of the cycle lengths (Ta to Tc) of the various control periodic signals (Da to Dc) to be given to the parameter setting circuit 35, and sets the values as important values. In addition, the set values of the cycle lengths (Ta to Tc) of various control periodic signals (Da to Dc) given to the parameter setting circuit 35 in response to the selection operation of the second object 50c are emphasized. Hold as a value.

  Therefore, according to this modification, when the first object 50b is selected in the setting mode, the through image displayed on the liquid crystal display 43 can be set to “appearance-oriented” thereafter, and the display area of the display object can be reduced. Regardless of the size, it is possible to provide a technology that can display a through image with a good image quality to ensure superiority in the market and can withstand image quality comparison with other products in stores. On the other hand, when the second object 50c is selected in the setting mode, the through image displayed on the liquid crystal display 43 can be set to “emphasis on reproducibility” thereafter, which is different from the actually visible subject image. The merit that it is possible to eliminate the sense of incongruity by reducing the amount of the image is obtained.

  In the above description, by controlling the operation parameters of the color process circuit 34, the quality of the through image displayed on the liquid crystal display 43 is switched between the emphasis on appearance and the emphasis on reproducibility. However, the present invention is not limited to this embodiment. . In short, it is only necessary that the image quality of the through image finally changes. For example, the operation parameters of each part of the image display system 19, that is, the digital video encoder 42, or the operation parameters of the liquid crystal display 43 are directly operated. You may do it.
