Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image signal obtained by an image pickup device such as an image pickup tube or a CCD, which can visualize the image pickup data, for example, NTSC-RG.
The present invention belongs to the technical field of an image reproducing method and an image reproducing apparatus for converting into B or the like.

[0002]

2. Description of the Related Art Conventionally, in an image reproducing apparatus such as a television camera using an image pickup device such as a CCD, the same impression can always be obtained regardless of the aging change of the image pickup device or the color filter or the change of the illumination light source. In order to obtain a reproduced image that is as faithful as possible, or to obtain an image data that is as faithful as possible, it is common practice to determine some of the image reproduction parameters from the imaged data during the image reproduction process. There is. The image reproduction parameters include, for example, color temperature and reproduction brightness level, and the image reproduction parameters are used when correcting the color temperature and setting the reproduction brightness level. In the correction of the color temperature, specifically, so-called light balance adjustment is performed, and an object that should be white is adjusted so that it looks white. Then, this color temperature correction is generally judged and performed based on the imaged image data. That is, an object that should appear white is extracted from the image data, and the white balance coefficient that is a part of the image reproduction parameter is determined from this. In white balance adjustment, the white balance coefficient is used to correct gains by applying gains to the multiple color component signals that make up the video signal output by the image sensor. The output levels of the signals of the respective color components forming the signal are adjusted to be equal.

The reproduction brightness level is set by calculating the brightness distribution from the imaged data, setting the optimum reproduction brightness level (range), and adjusting the parameters so that a reproduced image can be obtained in that range.

[0004]

However, in the method of adjusting the color tone of the image by the white balance adjustment described above, when the image signal obtained from the image pickup device or the like has a sufficient amount of an object (subject) that should appear white. Is effective, but in certain situations, there may be no object (subject) that should appear white in the image signal, or there may be very few. Even in such situations, the color balance may be adjusted by white balance adjustment. Adjustment is impossible in principle. Generally, in such a situation, in order to avoid this state, the image pickup signals of the entire image pickup data may be averaged for each color component, and the white balance adjustment may be performed using the average value. Then, the color shown in the obtained average value is not always white (color of the light source), and white balance adjustment cannot be performed accurately.

As described above, in the conventional image reproducing apparatus, when the image reproducing process is performed in order to obtain the optimum reproduced image, if the image reproducing parameter is determined from the image pickup data, the parameter can be set accurately. There was a problem that I could not.

Further, in setting the reproduction brightness level,
When the luminance reproduction parameter is determined for each individual image data, the luminance correlation between a plurality of image data to be compared is lost when performing image comparison and the like, or when performing image combining processing, etc. There is a problem in that it may be difficult to make a comparison, or inconvenience may occur in the reproduced synthetic image such that the connection of the luminance becomes unnatural.

[0007] For example, in view of the shooting area, the above-mentioned problem becomes apparent when a plurality of image pickup data are obtained by dividing an image of a subject that should be imaged on the same screen.

That is, since the reproduced image obtained by using the image reproduction parameter obtained from the image information can obtain the individual image reproduction parameter for each image pickup data, as in the case of obtaining the physical property information or the like by the brightness information, It is not possible to obtain a reproduced image used for extracting information between images by comparing and analyzing a plurality of images. Alternatively, when the reflectance of the subject gradually changes spatially, there is a difference in the brightness level (range) in the individual image data obtained by dividing the image, and this When the image is reproduced by optimizing it for each imaged data, it is reproduced as an image in which the correlation of the brightness originally in each imaged region is lost. Therefore, the images captured in each imaged region are combined to form one image. Then, there is a problem that an unnatural synthetic image in which the correlation of luminance is lost is obtained.

The present invention has been made to solve such problems, and an object of the present invention is to provide an image reproducing method and an image reproducing apparatus capable of performing desired accurate image reproduction.

[0029]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of an image reproducing apparatus according to the present invention.

Reference numeral 10 denotes a color image pickup unit such as a digital camera, which picks up an image of a subject and outputs the subject image data as two-dimensional digital image pickup data (hereinafter, simply referred to as "image pickup data") to the image pickup data memory unit 20. To do. Then, the imaged data memory unit 20 includes the color image pickup unit 10
The image pickup data sent from is stored and saved.

The color image reproduction processing unit 30 performs a predetermined image reproduction process on the image pickup data stored and saved in the image pickup data memory unit 20, and, for example, digitized N.
It is converted into TSC-RGB data and output to the color image reproduction display unit 40 and the reproduction image data memory unit 50.

The color image reproduction display section 40 is provided with, for example, a color video board and a monitor, receives the color image signal output from the color image reproduction processing section 30, or receives the color image signal from the reproduction image data memory section 50. Is read out and displayed as a color image on the monitor.

The reproduced image data memory section 50 stores the image data reproduced in the color image reproduction processing section 30, and the stored image data is sent to the color image reproduction display section 40 as needed. It is displayed as a color image.

More specifically, the color image reproduction processing section 30 selects an image pickup data from the image pickup data holding mechanism 31 for holding the digital image pickup data from the image pickup data memory section 20 and the image pickup data memory section 20. The captured image data selection mechanism 33 that outputs the captured image data to the captured image data storage mechanism 31, the captured image data selection instruction unit (instructing means) 34 that indicates conditions for the captured image data selection unit 33 to select the captured image data, and the captured image data. The image reproduction of the imaged data held in the imaged data holding unit 31 is performed by using the image reproduction parameter determined by the image reproduction parameter determination unit 32 which determines the image parameter using the imaged data selectively held in the holding unit 31. And an image reproduction processing unit 35 for controlling the color image reproduction processing unit 30 and a control unit 36 for controlling each unit of the color image reproduction processing unit 30. To have.

The image reproduction parameters determined by the image reproduction parameter determination unit 32 are, for example, color temperature, white balance coefficient, color component gain amount, white point information, black point information, gamma coefficient, gradation characteristic, gradation conversion. Curve, gradation conversion lookup table, knee point, dynamic range, color gamut, illumination light source information, color coordinate conversion matrix coefficient, spatial frequency characteristic, black balance coefficient, S / N ratio, autocorrelation coefficient, Wiener spectrum, intensity Examples thereof include parameters indicating (density) distribution, luminance distribution, etc., or parameters obtained directly or indirectly from these information.

The picked-up image data selection instructing section 34 selects from a plurality of picked-up image data stored in the picked-up image data memory section 20.
In order to handle the imaged data satisfying a certain condition as a group of imaged data, it is possible to instruct a condition for selectively extracting. The instruction condition is, for example, the color temperature information obtained from the image pickup data, the condition for the composition of the image pickup subject, or information associated with the image pickup data, that is, the image pickup time, the image pickup mode, the image pickup place, the EV value, the aperture value, and the subject distance. , Shutter speed, use of strobe, presence of optical low-pass filter, etc.

FIG. 2 is a flow chart showing the image processing procedure of the image reproducing apparatus of this embodiment. This program is executed in the color image reproducing processing section 30. Further, it is assumed that the imaging data memory unit 20 already stores and holds a plurality of imaging data captured by the color image capturing unit 10.

When the flow chart shown in FIG. 2 starts, the control unit 36, which executes it, first checks the content of the image data selection instruction (step S1) of the image data selection instruction unit 34, and selects the image data selection instruction. Send to section 33. Next, based on the selection instruction content instructed by the imaging data selection instructing section 34, the imaging data selection section 33 selects the imaging data corresponding to the selection instruction content from the imaging data stored in the imaging data memory section 20. The data is selected and output to the imaging data holding unit 31 (S2). In addition,
This program is not executed when the number of pieces of image pickup data applicable to the selection instruction content is one or less, and when the number of pieces of selection image pickup data is one, the image pickup data is converted into image data by a normal image reproduction process. When there is no selected image pickup data, an instruction to that effect is issued, and a series of processing ends.

The image data holding section 31 temporarily holds the image data selected and output from the image data memory section 20 (S3).

The image reproduction parameter determining section 32 uses the image pickup data temporarily held in the image pickup data holding section 31,
After analyzing the imaged data and obtaining light source information (for example, color temperature or chromaticity of the light source) at the time of image pickup of the imaged data necessary for white balance adjustment, for example, an image reproduction parameter based on the light source information. Is determined (S4). That is, the image reproduction parameter determination unit 32 determines the image reproduction parameter by using the plurality of image pickup data selected and held as the image pickup data group, and sends the image reproduction parameter to the image reproduction processing device mechanism 35.

The image reproduction processing section 35 uses the decided image reproduction parameters to convert the image pickup data forming the image pickup data group held by the image pickup data holding section 31 into image data (S5).

Next, the conditions for selecting image pickup data, which should be treated as a series of image pickup data from a plurality of image pickup data, will be listed.

Information obtained from the analysis of the imaged data itself includes color temperature information and the composition of the imaged subject. It may be necessary to treat a plurality of image data whose color temperature is within a certain range as a group of correlated image data.
Especially when the number of sample points used for the color temperature estimation is small, the estimation accuracy can be improved by performing the color temperature estimation again using a plurality of imaging data in which the estimated color temperature is within a certain range. Therefore, the image can be reproduced with high accuracy.

When the composition of the imaged subject is the same or very similar, there is a high possibility that the images were taken under the same imaging conditions. Therefore, the reproduction parameters can be treated as the same or the same within a certain accuracy range. In such a case, if the reproduction parameter is obtained from a plurality of image data, the reproduction parameter can be obtained with high accuracy, and the composition of the imaged subject is the same.
Alternatively, it may be useful to handle image data that are very similar to each other in a series of image data sets.

Information useful for grasping the correlation of the image pickup data includes, for example, image pickup time (date), image pickup mode, image pickup location, EV value, shutter speed, aperture value, subject distance, use of strobe, and optical low pass. Whether there is a filter or not. When these pieces of information are given as information accompanying the image pickup data, it is possible to generate a series of image pickup data groups by analyzing this information.

For example, when the imaging time is within a certain range, it is obviously effective to treat it as a series of imaging data groups. It is also clear that it is effective to handle a series of imaged data whose image capturing mode is continuous shooting mode as one group. Information on whether or not a strobe is used, for example, information on a shooting light source when a strobe is used largely depends on the characteristics of the strobe light, so it is useful to collectively handle a plurality of image pickup data shot by using a strobe as an image pickup data group. is there.

The EV value, shutter speed, aperture value,
The information such as the subject distance greatly depends on the shooting conditions, and is a strong constraint condition in determining the reproduction parameters.
Therefore, if the image pickup data whose values are in a certain range is treated as one image pickup data group, it becomes very efficient when performing image reproduction.

The information about the shooting location is information that makes the characteristics of the subject image the same, and is very effective in accurately reproducing the subject. Furthermore, when considered in combination with information such as the shooting time (date), it is clear that information on changes in the imaging conditions and the like can be obtained, and the usefulness thereof is increased.

In the above example, the conditions for individual information are mainly mentioned, but it is obvious that the combination of the above conditions may be more effective in some cases.

Further, as a processing condition, for example, there is a case where a plurality of image data having spatial continuity are designated to obtain a composite image, as shown in FIG. In such a case, it is necessary to maintain spatial continuity as a composite image. Therefore, it is very effective to perform image reproduction processing by treating the above plurality of image pickup data as a series of image pickup data groups. Becomes

Alternatively, as shown in FIG. 4, in the case of image pickup data which has temporal continuity and can be determined to be almost the same in the subject image based on the photographing location information and the composition information obtained by analyzing the image pickup data, According to the image reproducing method and apparatus of the present invention, a reproduced image with temporal continuity can be obtained by treating it as a series of captured image data.

For example, if the image data is obtained outdoors, it is possible to reproduce the image while holding the image capturing time, that is, the continuous change due to the change of the sunshine condition. In particular,
Regarding the image data of the image data group consisting of a plurality of image data whose subject images are almost the same, by continuously changing the image reproduction parameters according to the information of the image capturing time, it is possible to have temporal continuity. A reproduced image can be obtained. As a result, it is possible to correct the disturbance that has occurred in a part of the imaged data due to a sudden change in the condition and to reproduce the image, so that it is possible to obtain a temporally natural image.

Further, as shown in FIG. 5, there is continuity in time and continuity in the order of imaging, that is, the shooting mode is continuous shooting mode or spatial continuity. By treating the image pickup data as a series of image pickup data groups, it is possible to exclude the different conditions occurring in the individual pieces of image pickup data, so that it is possible to reproduce the images with continuity.

The method of grouping the imaged data, that is, a series of imaged data groups, using the color temperature information, which is the information obtained from the analysis of the imaged data itself, will be described in detail below. FIG. 6 shows a flowchart thereof.

The conditions given by the image pickup selection instructing section 34 are the correlated color temperature (A (K)) and the selected range color temperature (±
dA (K)). The correlated color temperature range may be directly and numerically input by the user, or information related to the correlated color temperature, for example, day, evening, sunset, cloudiness, words of incandescent lamp, color, etc. By inputting information that can be assumed by the user about the temperature, it is also possible to call it from the storage unit that has previously defined and stored the color temperature range corresponding to them on the system side and use it. Is also possible (step S1 in FIG. 6).
1). It is also possible to use adjectives such as red and pale, which can assume the color temperature, and specifically use chromaticity values, color difference values, and the like.

By instructing the above conditions, the correlated color temperature, which is information unique to the image pickup data, can be specified using, for example, the chromaticity diagram shown in FIG.

[0058]

[Equation 1]

The above conditions are sent to the image pickup data selection section 33 and used as grouping conditions.

The image pickup data selection section 33 sequentially reads the image pickup data stored in the image data memory section 20 (S12), analyzes the image pickup data and extracts information on the color temperature (S13), and the previously designated group. It is determined whether or not the conversion condition is satisfied (S14), and if the condition is satisfied, the image pickup data is sent to the image pickup data holding unit 31 (S15).

[0061]

[Equation 2]

Next, a method of grouping the imaged data when the composition of the imaged subjects is instructed as a grouping condition will be described. FIG. 9 shows an example of the flowchart.

When the composition is designated as a grouping condition, the imaging data selection section 33 reads the imaging data stored in the image data memory section 20 (steps S21 and S22 in FIG. 9) to confirm the composition. Simple reproduction is performed to some extent (S23), and simple reproduction image data is obtained. The simple reproduction may be a reproduction process that allows the composition to be confirmed. For example, pixels may be thinned out from the imaged data to suppress the data amount and then reproduced as luminance data.

Next, the grouping judgment is made using the simple reproduction image data (S29). In determining the similarity of images, the subjective judgment is generally effective, but the subjective judgment method is also used in the present invention. That is, in the grouping judgment, when a judgment instruction from the user can be expected, a series of simple reproduction image data is displayed on a monitor or the like (S25), and a means for the user to select an image to be grouped is provided and selected by the user. The captured image data corresponding to the captured images are sequentially captured by the captured image data holding unit 3.
1 and is held there (S26, S30).

For example, when the grouping determination is automatically performed, the following procedure is performed. That is, edge image data in which edge components are extracted from the simple reproduction image data is formed, and the identity, similarity, etc. of the spatial relationship of edges are detected by applying image processing technology (S27, S28). Then, the spatial correlation obtained from the analysis of the identity, the similarity, etc. is examined, and the image having a strong correlation is judged as an image satisfying the grouping condition, and is sent to the imaging data holding unit 31 and held there. (S29, S30). Next, a method of grouping the imaged data using information attached to the imaged data will be described. FIG. 10 shows a flowchart showing the operation example.

When the information attached to the image pickup data and the condition therefor are given to the image pickup data selection instructing section 34 as a condition for grouping, the image pickup data selecting section 33 stores the information in the image data memory section 20. It is checked whether or not the information corresponding to the condition is added to the captured image data, and the captured data to which the information is added is sequentially read (steps S31 and S32 in FIG. 10). Then, it is checked whether or not the associated data satisfies the grouping condition (S33, S34).

The condition for grouping is, for example, if the information can be set numerically such as the image pickup time, EV value, aperture value, subject distance, shutter speed, etc., the range indicated numerically The condition is whether or not there is the information value. Shooting mode, shooting location, use of strobe,
The condition when using information that is difficult to be shown numerically, such as information about the presence or absence of an optical low-pass filter, is, for example, whether or not the place name, the mode name, and the presence or absence thereof match.
Alternatively, grouping information according to the image capturing mode (the same mark is attached to the image capturing data taken in the series of continuous shooting modes) or grouping information according to the image capturing location (for the data captured at the same location, (The same mark is given), etc., is given as ancillary data,
The condition is that the given marks match. The image pickup data satisfying the conditions are sequentially sent to the image pickup data holding unit 31 (S3
5, S36), and held there.

Next, at the time of image reproduction, for example, Japanese Patent Laid-Open No. 7-1
For the purpose of expanding the dynamic range disclosed in Japanese Patent No. 31796 to obtain a composite image, or for example, from a plurality of imaging data disclosed in Japanese Patent Laid-Open No. 5-183789, a wide-angle captured image is obtained. When obtaining a composite image by the method of panorama image composition,
A method of grouping image pickup data will be described. In such a case, it is desirable that the captured data for obtaining a certain composite image be added as the accompanying information at the time of capturing. In such a case, in the present embodiment, the image pickup data forming the image pickup data group is selected and grouped on the basis of the accompanying information. Alternatively, by using the composition information, the imaging data is simply reproduced as shown at the time of grouping the imaging data, the grouping judgment is performed,
Imaging data can be grouped. Further, in the process of obtaining the composite image, all the data in the image data memory unit 20 may be selected in advance as the imaged data to be treated as a group when the process is executed. In such a case, the present invention treats all the image pickup data in the image data memory section 20 as a series of image pickup data and reproduces the image.

As can be seen from the above-described embodiments, the gist of the present invention is to convert the image data into image signals.
A plurality of image pickup data satisfying a certain condition are treated as a series of image pickup data groups, the image reproduction parameters are obtained from the series of image pickup data groups, and the image pickup data belonging to the image pickup data groups are imaged using the image reproduction parameters. It is about converting to data. Therefore, various sequence processes can be considered without departing from the gist of the present invention. These sequence processes can be applied, for example, as hardware or a device that is logicalized or softwareized, or is algorithmized within the scope of the gist of the present invention, and operates according to this algorithm.

[0070]

As described above, according to the present invention,
A plurality of image pickup data satisfying a certain condition are treated as a series of image pickup data groups, the image reproduction parameters are obtained from the series of image pickup data groups, and the image pickup data belonging to the image pickup data groups are imaged using the image reproduction parameters. Since the data can be converted into data, if the image reproduction parameters are to be decided from the imaged data as in the conventional image reproduction processing method, the conditions for parameter determination are generally not satisfied, and the parameters can be obtained accurately. The present invention can cope with such a problem that the image data cannot be obtained, and the image data can be converted into the image data by using a more accurate image reproduction parameter, and the image can be reproduced accurately. Further, it is possible to prevent the disappearance of the correlation between the imaged data caused by performing the reproduction process using different image reproduction parameters for each image (imaged data), and the information and the correlation between the images are retained. Since the captured data can be converted into image data using a more accurate image reproduction parameter, a natural and accurate image can be reproduced.
