Abstract
In order to facilitate evaluation of each of two or more to-be-measured objects individually, in the two-dimensional image processing apparatus, image data representing a two-dimensional image is acquired and two or more to-be-processed regions are set in the two- . One or more to-be-processed regions are selected from two or more to-be-processed regions, and processing conditions to be applied to the selected one or more to-be-processed regions are set. Either or both of the color data and the luminance data in one or more areas to be processed are acquired from the image data and processed.
Description
The present invention relates to a two-dimensional image data processing device, a two-dimensional color intensity meter, a two-dimensional image data processing method, and a two-dimensional image data processing program.
Flat panel displays (FPDs) include liquid crystal displays, plasma displays, and organic electroluminescent (EL) displays. When these FPDs are evaluated, a two-dimensional color luminance meter is used to evaluate luminance unevenness or color unevenness in the display screen. When an FPD is evaluated using a two-dimensional color luminance meter, there are times when one FPD is measured and a plurality of FPDs are measured at a time.
When a plurality of FPDs are measured at one time, a plurality of FPDs are arranged on the same plane, and a two-dimensional color luminance meter is provided apart from the arranged plurality of FPDs. Then, image data (two-dimensional image data) expressing a two-dimensional image in which a plurality of FPDs are picked up is generated. Chromaticity data or luminance data is acquired from the two-dimensional image data. Chromaticity data or luminance data is mapped to a pseudo color scale, and a pseudo color representation of a two-dimensional distribution of chromaticity or luminance is drawn. Other processing may be performed. Conventionally, the processing conditions for the evaluation values of a plurality of FPDs picked up in one two-dimensional image are uniform, and the same processing has been performed for all the two-dimensional image data. Therefore, for example, when processing conditions applied to each of a plurality of FPDs are different, a portion corresponding to each of a plurality of FPDs must be cut out from the two-dimensional image data, and from each of the cut- Chromaticity data or luminance data is obtained. Thus, by separating the two-dimensional image data corresponding to a plurality of FPDs, processing conditions unique to each of the FPDs can be applied to process chromaticity data or luminance data.
In the two-dimensional color system of
In the conventional two-dimensional color luminance meter, it is not possible to individually evaluate each of the plurality of FPDs captured at the same time. For example, the user needs to separately separate the data of the FPD area in the two-dimensional image and evaluate them individually. This problem occurs even when the measured object is other than the FPD.
An object of the present invention is to facilitate evaluation of each of two or more objects to be measured simultaneously captured.
The present invention relates to a two-dimensional image data processing apparatus.
In order to realize the above object, in a two-dimensional image data processing apparatus according to an aspect of the present invention, image data is acquired. Two-dimensional image data represents a two-dimensional image. Two or more areas to be processed are set in the two-dimensional image. At least one to-be-processed region is selected without leaving at least one to-be-processed region from two or more to-be-processed regions. Processing conditions to be applied to the selected one or more processed regions are set. The processing conditions are applied so that either or both of the color data and the luminance data in one or more areas to be processed are acquired and processed from the two-dimensional image data.
The present invention can also be applied to a two-dimensional color intensity meter, a two-dimensional image data processing method, and a two-dimensional image data processing program.
The two-dimensional image data processing apparatus according to an embodiment of the present invention and the two-dimensional color intensity meter, the two-dimensional image data processing method, and the two-dimensional image data processing program according to another embodiment, Can be evaluated individually.
These and other objects, features, aspects and advantages of the present invention will become more apparent from the following detailed description of the present invention when considered in conjunction with the accompanying drawings.
