Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an imaging apparatus, and more particularly, to an imaging apparatus that performs imaging by analyzing output information of imaging means that images a subject.
[0002]
[Prior art]
Conventionally, when setting an imaging area, an imaging apparatus such as a still camera or a video camera generally sets an imaging area of a subject via a monitor provided with a small finder window provided in the imaging apparatus.
[0003]
[Problems to be solved by the invention]
However, this type of image pickup apparatus has a drawback that the line of sight of the photographer faces the monitor or the like and does not face the subject, so that the line of sight cannot be matched with the subject.
[0004]
In addition, it is necessary to lift the camera unit close to the face when shooting, and this makes the camera shooting action aware of both the photographer and the person to be photographed. The trick was necessary.
[0005]
On the other hand, due to the progress of recording technology, the downsizing of the image information recording apparatus is remarkable, but the finder portion is not improved, and only the finder portion becomes relatively disproportionately large, which is not preferable in terms of operability and design. There was a problem.
[0006]
In addition, while miniaturization of recording media and further power saving by electronic technology are progressing, as the popularity of camera-integrated video cameras with large color liquid crystal display units has increased, an easy-to-use finder system has been pursued. There is a problem that power consumption of the entire apparatus has increased in the process.
[0007]
Accordingly, an object of the present invention is to solve such a problem and to provide an imaging apparatus that can reduce the burden of a photographing operation and can photograph a subject with a simple configuration.
[0008]
[Means for Solving the Problems]
An image pickup apparatus according to the present invention includes: subject An image pickup system including an image pickup means for picking up images, an image recognition means for analyzing output information of the image pickup means, and an image pickup control means for controlling the image pickup system based on the recognized image are provided. In this case, image information in the imaging area determined by the controlled imaging system is recorded.
[0011]
Furthermore, in the present invention, there are provided imaging mode setting means for setting the imaging ratio of the subject, and means for setting the recording area in the optimum aspect determined according to the information set by the imaging mode means. An imaging system is controlled based on the determined subject information and the set imaging mode, and image information in the recording area of the optimum aspect is recorded. In this case, the imaging system is controlled so that the ratio of the subject to the recording area determined by the image recognition unit becomes the imaging ratio set by the imaging mode setting unit.
[0012]
In the embodiment of the present invention, there is provided light projecting means capable of projecting a target light beam substantially parallel to the extension line of the optical axis of the imaging system, and this index light beam (pointer) is projected onto a desired subject. The orientation of the imaging device is adjusted so that the index light beam is located approximately at the center of the subject. In this state, an image signal having a desired subject substantially in the center is obtained from the image pickup means provided in the image pickup system. The image signal is analyzed by the image recognition means, the boundary line of the subject is detected, and the subject region is recognized. The imaging angle of view is controlled so that the ratio between the recognized subject area and the imaging area matches a predetermined value or a ratio set by the photographer using the imaging mode setting means. The imaging angle of view is mainly adjusted by an optical zoom unit, but an electronic zoom unit is also used if necessary. When the imaging field angle is set to a desired state, information on a recording area in the imaging signal is recorded. In this case, the recording area can be set to an optimum aspect ratio (aspect ratio) corresponding to the imaging mode.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings.
[0014]
[overall structure]
FIG. 1 is a block diagram illustrating the basic configuration of an imaging apparatus according to an embodiment of the present invention. The imaging apparatus includes an imaging unit 11, an imaging region setting unit 12, a pointing unit 13, an image analysis unit 14, and a manual operation unit 15. The photographer operates the manual operation means 15 to give a power-on or standby instruction to the apparatus. Upon receiving this instruction, the pointing means 13 projects a visible ray (index ray) substantially parallel to the optical axis of the optical system of the imaging means 11 toward the subject 10. The imaging means 11 photoelectrically converts the image of the subject 10 and outputs it as an imaging signal (video signal). The image analysis unit 14 detects the area of the subject image by image recognition processing based on the imaging signal, and the imaging area setting unit 12 captures information on the subject area obtained from the image analysis unit and the imaging set by the manual operation unit. An imaging area (and recording area) is determined based on information such as the mode.
[0015]
[Detailed configuration of each means]
2 to 4 show more detailed configurations of the respective means. The operation key switch detection means 27 has switches SW1 and SW2. When the photographer turns on the switch SW1, the operation key switch detection means 27 detects this, and gives a light emission instruction to the index generator 24 constituting the pointing means 13. Output. In response to a light emission instruction, an index light beam from a light emitting member such as a semiconductor laser provided in the index generator 24 is projected onto the subject 10 through the light projecting optical system 21. As shown in FIG. 3, this is performed by the semiconductor laser 24a in the index generator 24 being driven by the laser driver 24b in response to the control signal, so that the visible light from the semiconductor laser 24a is reflected by the subject 10. Will be flooded.
[0016]
In this case, the orientation of the image pickup apparatus is manually adjusted so that the index light is emitted to the approximate center of the desired subject 10. Although not shown, it is also possible to provide driving means such as a motor and automatically control the orientation of the imaging apparatus by a servo mechanism.
[0017]
The subject image onto which the index light is projected is imaged on an image sensor (for example, CCD) 25 via the imaging optical system 22. A signal output from the image sensor 25 is output as an image signal or a video signal by the video camera system signal processing circuit 28 and input to the electronic zoom means 31.
[0018]
When recording is started, the light emission is stopped so that the pointer light by the visible light is not imaged.
[0019]
The image pickup system has various general characteristic adjustment functions, and various adjustments are performed via the optical system control means 35 by signals from the signal processing circuit 28. For example, one of them is an automatic focus adjustment function based on a so-called TV-AF method using information of the video camera system signal processing circuit 28. As shown in FIG. 3, the automatic focus control circuit 35a of the optical system control means 35 receives the signal from the video camera system signal processing circuit 28 and the focus adjustment optical system of the imaging optical system 22 via the drive signal C3. The focus adjustment of 22a is performed.
[0020]
Further, an automatic exposure adjustment function based on the so-called video AE method based on similar information is performed. In this case, the automatic exposure control circuit 35b of the optical system control means 35 controls the opening of the incident light amount adjusting member (iris or the like) 22b of the imaging optical system 22 via the drive signal C2 to perform optimum exposure.
[0021]
Further, as will be described later, the optical zoom control circuit 35 of the optical system control means 35 driven by an instruction from the system control circuit 30B based on the image analysis by the pattern recognition processing means 32 (image analysis means 14) is a drive signal C1. Is supplied to the variable magnification optical system 22c of the image pickup optical system 22, and zoom magnification adjustment (field angle adjustment / focal length adjustment) is performed.
[0022]
Further, the output of the video camera system signal processing circuit 28 is input to the electronic zoom means 31, where an imaging area is extracted, so-called electronic trimming processing is performed to set a recording area. The pattern recognition processing means 32 detects the subject area based on the information subjected to the trimming process from the electronic zoom means 31, calculates the area ratio of the subject area, and is determined by a predetermined value indicating the photographing magnification or the imaging mode. The imaging system and the recording area are set by controlling the optical system control unit 35 and the electronic zoom unit 31 through the system control circuit 30B so as to obtain a predetermined magnification.
[0023]
FIG. 4 shows a detailed configuration of the pattern recognition processing means 32. The pattern recognition processing unit 32 includes an edge detection processing unit 32a, a color area detection processing unit 32b, a frequency discrimination (detection) processing unit 32c, a motion detection processing unit 32d, a pattern recognition unit 32e, and a comparison unit 32f.
[0024]
The edge detection processing means 32a detects the change point of the image area based on the horizontal and vertical differential coefficients based on the signal from the electronic zoom means 31, and determines the continuity of the change point to determine the subject area. It has a function to discriminate.
[0025]
The color area detection processing unit 32b has a function of discriminating a subject area by grouping color information for each predetermined range based on a signal from the electronic zoom unit 31 and determining the continuity of the belonging range of each color.
[0026]
The frequency discrimination processing unit 32c has a function of discriminating the subject region by judging the continuity of the spatial frequency. As a specific example, as a characteristic unique to camera shooting, when the depth of field is shallow, there is a high possibility that the high-frequency component of only the desired subject is increased by the automatic focusing means. This makes it possible to distinguish the main subject from the background.
[0027]
The motion detection processing unit 32d has a function of discriminating a subject area by using the fact that a desired subject is likely to have a motion pattern different from that of another person or background. The actual configuration of the apparatus can also be used when the area resolution capability of the image motion detection means used in recent video camera shake correction apparatuses and the like is more than a predetermined value.
[0028]
The pattern recognizing unit 32e comprehensively uses the information preprocessed in these detection processes to determine the area of the subject, and calculates the ratio of the subject area in the current imaging area (subject area ratio). . The comparison unit 32f compares this value with a predetermined value set in advance or a set value that can be set by the shooting magnification set by the photographer. The optical system control unit 35 and the electronic zoom unit 31 are controlled according to the comparison result, and the imaging system is set to the imaging magnification set by the photographer.
[0029]
In this way, when the imaging system is adjusted to the imaging magnification set by the photographer and the switch SW2 is turned on by the photographer, this is detected by the operation key switch detection means 27, and the system control circuit 30A shown in FIG. Is transmitted to. In response to this, the system control circuit 30A performs information compression processing on the captured image information subjected to trimming processing supplied from the electronic zoom means in the image compression means 33, and converts the compressed image information into image information. Store in the storage memory 34. In this case, the final angle of view is adjusted as necessary in accordance with the operation of the switch SW2.
[0030]
In the image information compression processing performed by the image compression means 33, in addition to conventional methods such as sub-sampling and nonlinear quantization, each of the current mainstream methods based on DCT including so-called JPEG In addition, a compression method using image recognition classified as fractal coding or intelligent coding, or hierarchical coding such as pyramid coding is used. When the capacity of the arithmetic processing device is sufficient, it is preferable that the pattern recognition processing and the image compression processing are performed by the same arithmetic processing device (microprocessor). Further, in the case of direct conversion type image compression, it is preferable in terms of processing efficiency and image quality deterioration prevention to perform the trimming process and the image compression process in a series of arithmetic processing procedures.
[0031]
The storage memory 34 is, for example, a semiconductor memory such as an S-RAM, D-RAM, EEPROM, or flash memory, a magnetic recording medium such as a magnetic tape or a hard disk, or an MO (magneto-optical disk) or PD (phase-change disk). ) And other magneto-optical effect type recording media.
[0032]
[Operation sequence]
Next, an operation sequence of the imaging apparatus configured as described above will be described with reference to a flowchart shown in FIG.
[0033]
First, as shown in step S1 as a main routine, the trimming means is initialized, and the optical system control means 35 and the electronic zoom means 31 are initialized to the wide end.
[0034]
Subsequently, in step S2, it is determined whether or not the switch SW1 is pressed. When the photographer turns on the switch SW1, the operation key switch detection unit 27 detects the depression of the switch SW1, and turns on the pointer in step S3. By this operation, a control signal is generated in response to an imaging standby instruction, and in response to this, the semiconductor laser 24a in the index generator 24 is driven by the laser driver 24b to generate visible light that serves as an index. The visible light is projected through the light projecting optical system 21 so that the optical axis is substantially parallel to the imaging optical system 22 and an object at infinity.
[0035]
The subject image on which the index light is projected is an imaging optical system 22 including a focus adjustment optical system 22a for adjusting the imaging focus, an incident light amount adjustment member 22b such as an iris, and a variable magnification optical system 22c for controlling the imaging magnification. Then, an image is formed on the image sensor 25 such as a CCD or MOS device (FIG. 3). The signal output from the image sensor 25 is processed by the video camera system signal processing circuit 28 and output as a video signal.
[0036]
At this time, a subroutine is called at the same time, and a pointer is irradiated to a desired subject (target) while adjusting the angle of view in the subroutine.
[0037]
In the subroutine, a predetermined value of the screen ratio of the subject is read in step S10. This corresponds to inputting a predetermined value to the comparison unit 32f of the pattern recognition processing unit 32 of FIG. This predetermined value is a numerical value corresponding to the photographing magnification, and P (1) / {P (0) + P when the imaging region is divided into white P (0) and the subject image region is divided into black P (1). (1)}.
[0038]
Subsequently, in step S11, image recognition processing is performed by the following processing using the pattern recognition processing means 32. The image information trimmed by the electronic zoom means 31 is supplied to various processing means such as an edge detection processing means 32a, a color area detection processing means 32b, a frequency discrimination processing means 32c, and a motion detection processing means 32d. By comprehensively using information obtained by each function, the pattern recognition means 32e in the next stage determines the subject area and counts the number of pixels in the subject area (corresponding to P (1)). Also, a predetermined shape surrounding the subject is defined, and this is set as a recording region. Similarly, the number of pixels in the recording region (corresponding to P (0)) is counted, and the subject region in the current imaging region is counted. The occupying ratio is digitized by the ratio of (1) / {P (0) + P (1)} and supplied to the comparison means 32f.
[0039]
The comparison unit 32f compares the digitized value with the predetermined value read in step S10, generates a correction control signal, and controls the imaging angle of view so that they match. That is, based on the comparison result, the optical zoom control circuit 35c controls the image magnification of the variable magnification optical system 22c according to an instruction from the system control circuit 30B, and performs angle of view adjustment (so-called zoom magnification adjustment) (step S12). At this time, if there is a change in the focus or the exposure amount with the adjustment of the angle of view, the focal length adjustment or the exposure control is performed through the automatic focus control circuit 35a and the automatic exposure control circuit 35b as necessary. .
[0040]
That is, the focus adjustment optical system 22a is adjusted by the automatic focus control circuit 35a, and the focus adjustment is performed so as to form a clear image on the image sensor 25. This automatic focus adjustment function is realized by a so-called TV-AF system that uses the information of the video camera system signal processing circuit 28 and controls the focus adjustment optical system 22a so that the high-frequency component in the video signal is maximized. The
[0041]
Further, the automatic exposure control circuit 35b uses the information of the video camera system signal processing circuit 28 to input an appropriate amount of light such as an iris on the image sensor 25 so as to supply an appropriate light accumulation amount that falls within the dynamic range of the image sensor 25. The transmitted light amount characteristic of the light amount adjusting member 22b is controlled.
[0042]
In step S13, the tele (telephoto / enlargement direction) or wide (wide angle / reduction direction) end of the optical system is detected. In step S14, the correction process is continued until each end is reached, and the desired angle of view is driven. If the optical end is detected or if it matches the desired angle of view, the process returns to the main routine.
[0043]
As described above, when the pointer is irradiated to the center of the desired subject and a desired angle of view is obtained (step S4), the photographer operates the switch SW2. When pressing of the switch SW2 is detected in step S5, the subroutine is called again. The subroutine is called at an arbitrary time, and the final optical adjustment (view angle adjustment) is ensured by calling the subroutine again in this way.
[0044]
In step S6, when it is determined in step S13 of the subroutine that the optical end has been reached, the electronic field zoom unit 31 performs final correction of the angle of view. The electronic trimming process by the electronic zoom means 31 controls the enlargement center coordinates, the enlargement / reduction direction (sign plus / minus sign), and the enlargement / reduction ratio as parameters. This control characteristic is shown in FIG. In this example, trimming at a magnification of 16 times is possible with the optical zoom, trimming at a magnification of 2 is possible with the electronic zoom, and a total trimming of 32 times is possible. Here, if the current magnification is low with respect to the set magnification target value, correction is performed in the enlargement direction, and conversely, if the current magnification is high, control is performed in the reduction direction.
[0045]
As described above, the trimming process is performed by the optical process by the optical system control unit 35 and the electronic process by the electronic zoom unit 31, but the initial setting is not performed by the electronic process. First, the optical process is performed and the optical process is performed. The electronic trimming process starts after reaching the zooming limit.
[0046]
In this way, when the imaging angle of view is set to a desired state, in step S7, the pointer is turned off in order to prevent the pointer light from visible light from being imaged, and in step S8, the recording area in the imaging signal is set. Record information. At this time, the system control circuit 30A compresses the image signal from the electronic zoom means set to the desired imaging angle of view by the image compression circuit and stores it in the image information storage memory 34.
[0047]
In this way, the imaging and recording process is performed. If there is no next imaging, the process is terminated.
[0048]
[Other embodiments]
In the embodiment described above, the imaging mode for setting the imaging ratio of the subject is fixed, but examples in which the photographer can select the imaging mode are shown in FIGS. 7 and 8. In this figure, the same parts as those in FIGS. 2 and 4 are denoted by the same reference numerals, and the description thereof is omitted.
[0049]
Regarding the imaging mode selection, the photographer inputs imaging mode selection information to the mode setting means 40 via the manual operation means 15 of FIG. Display information corresponding to the input mode information is generated by the icon pattern generation circuit 41. As an example, a graphical icon pattern that is frequently used in personal computers recently is generated and displayed by icon display means 42 such as a liquid crystal display. As an example of the display of this icon pattern, the image of the magnification of mode 3 in large, medium and small mode-A, mode-B, and mode-C is shown in the frame of the icon display means 42 in FIG. The photographer selects the photographing magnification by this picture display. The photographing magnification set here is input as a numerical value to the comparison unit 32 f of the pattern recognition processing unit 32.
[0050]
In such a configuration, the photographer inputs a desired photographing magnification from the three modes of mode-A, mode-B, and mode-C shown in the mode setting unit 40 or the icon display unit 42. Here, a case where mode-A having the highest photographing magnification is selected will be described. Display information corresponding to the input mode information is generated by the pattern generation circuit 41 and displayed on the icon display means 42, and at the same time, a numerical value corresponding to the set photographing magnification is output to the pattern recognition processing means 32. The numerical value corresponding to this magnification is the ratio of P (1) / {P (0) + P (1)} when the imaging area is divided into white P (0) and the subject image area is divided into black P (1). It is digitized and stored in a form corresponding to each mode, and the corresponding numerical value in this is output to the comparison means 32f of the pattern recognition processing means 32 in accordance with the set imaging mode. The comparison unit 32f generates control signals to the optical system control unit 35 and the electronic zoom unit 31 and sets the ratio of the subject to the imaging area in the imaging mode setting unit, as described in the first embodiment. The imaging angle of view is optically or electronically controlled so that the obtained imaging ratio is obtained.
[0051]
FIG. 9 shows another example of icon display. For each mode, an image diagram of the shooting situation, a mode, an icon, and setting values stored in the memory are shown from the left. . Mode-A is an up-shot and the main subject occupies 70% of the screen, mode-B is a bust shot and 40% of the main subject occupies the mode, and mode-C is a long shot. -It is shown that the main subject occupies 20% of the screen in the shot.
[0052]
In the above example, the method for setting the screen ratio of the subject by selecting several types of imaging modes using icons has been described. However, the present invention is not limited to this, and a numerical value is previously set using a conventional zoom lever type operation member. Of course, it is possible to set a continuous screen ratio by inputting. Furthermore, in response to the operation of the zoom lever type operation member, the size / form of the icon is continuously changed, and a continuous screen ratio can be set in a graphical operation form without using numerical values. Can be possible.
[0053]
In the embodiment described above, since the photographer can select the photographing ratio of the subject in advance, there is no need to adjust while looking through the viewfinder, and the operability is remarkably improved.
[0054]
[Still another embodiment]
In each of the above-described embodiments, the shape of the imaging region is always constant regardless of the shape of the subject, but the aspect ratio of the recording region can also be optimized. As shown in FIG. 10, the aspect ratio is set for each mode. That is, mode-A is an up shot, and 70% of the screen is occupied by the main subject, and the aspect ratio is 1: 1. Mode-B is a bust shot and the main subject occupies 40% of the screen, and the aspect ratio is 4: 3. Mode-C is a long shot and the main subject occupies 20% of the screen. The aspect ratio is 9:16.
[0055]
Mode-A is a mode for up, and the icon indicates a human head and the pixel ratio is registered as 70%. As a result, when the photographer confirms the scene as shown in the upper left diagram of FIG. 10 and presses the switch to turn on SW2, the minimum necessary rectangle is selected by the image recognition processing of the pattern recognition processing means 32, and the vertical and horizontal directions of the screen are selected. A square imaging recording area with an aspect ratio of 1: 1 is determined, and image data corresponding to this area is recorded in the storage memory 34 via the system control circuit 30A.
[0056]
Mode-B is a mode for bust shot, in which the icon indicates the upper body of a person and the pixel ratio is registered as 40%. As a result, when the photographer confirms the scene as shown in the left middle figure and presses the switch to turn on SW2, similarly, the minimum necessary rectangle is selected by image recognition processing, and the aspect ratio of the aspect ratio of the screen is 4 An imaging recording area in which the current television system of pair 3 is set in the vertical position is determined, and image data corresponding to this area is recorded in the memory 34.
[0057]
On the other hand, mode-C is a mode for landscape photography, where the icon indicates the distant view of the mountain and the pixel ratio is registered as 20%. As a result, the photographer confirms the scene as shown in the lower left figure and switches the switch. When the SW2 is turned on by pushing it in, the minimum necessary rectangle is selected by the image recognition process, and an imaging recording area equivalent to the high-definition television system having the aspect ratio of 9 to 16 on the screen is determined. Image data corresponding to this area is similarly recorded in the memory 34.
[0058]
As described above, the icons are square in any mode, but an optimum aspect ratio is selected for each of the imaging and recording areas in accordance with the recording scene. In this case, the area ratio occupied by the subject in the imaging / recording area set with the optimum aspect ratio is controlled to be the above-described setting values.
[0059]
Note that the aspect ratio is not limited to the above example. For example, when mode-B is selected and there is only one subject, a 4: 3 vertical region is set as shown in the center of FIG. However, when there are two subjects, a horizontal 3: 4 region can be set, and when there are three subjects, a 1: 2 region can be set.
[0060]
[Application example]
FIG. 11 is an external view of an example in which the above-described imaging device is applied to, for example, a still camera or a video camera. A light projecting member 51 (pointing means 13) and an imaging lens 52 (imaging means 11) are arranged on the front surface of the camera, and a shutter (trigger) switch 57 (switch) for instructing imaging timing is provided above the imaging apparatus. SW1, SW2) are arranged. When this switch is actuated, the irradiation light 53 is projected toward the subject 10 from the light projecting member 51 substantially parallel to the optical axis of the imaging optical system. Further, the image light beam 54 from the subject enters the imaging lens 52, and imaging becomes possible. Reference numeral 58 denotes an icon display unit (icon display means 42) provided when the imaging ratio is displayed as an icon when setting the imaging ratio.
[0061]
【The invention's effect】
Thus, in the present invention, subject If the shooting ratio is set or selected in advance, it is not necessary to adjust the angle of view while looking through the viewfinder, and the operability during imaging is significantly improved. In this case, the optimum aspect ratio can be set.
[0062]
Furthermore, in the present invention, the finder portion has been improved, and in response to the downsizing of the image information recording apparatus that has been remarkably downsized in recent years, the finder portion can be made power-saving to have a shape that is balanced in design. Can contribute to downsizing
