Problems solved by technology

However, such buying and selling is based on the image of the product displayed on an electronic display device obtained through the Internet or CD-ROM, etc., which raises a problem that the viewer may have a different impression of the color of the product depending on the display device used. is the diversity of display devices as described above
[0005] Also, although the colors of the image data can be reliably reproduced under certain conditions, objects in the image data may appear differently when viewed under different conditions

[0074] The present invention will be described in detail below in conjunction with the accompanying drawings. In a preferred embodiment of the present invention, as figure 1 As shown, the image processing apparatus 1 is connected to a plurality of client devices 3a, 3b through an electronic communication network 2 .

[0075] The image database 11 of the image processing apparatus 1 stores image data to be supplied to the client device 3 via the electronic communication network 2 and test image data to be used to obtain information on the display state of the client device 3 . The test image data includes a plurality of test pattern images for determining luminance characteristics as color expression characteristics, and for determining display luminance characteristics of respective primary colors as color balance characteristics. These test patterns include a first test pattern and a second test pattern. The first test pattern consists of arrayed pattern elements that vary ...

[0134] The image processing apparatus in the second preferred embodiment of the present invention is a stand-alone personal computer. In short, the image processing apparatus 20 in this embodiment includes a central processing unit 21, a random access memory 22, a read-only memory 23, a hard disk 24, a CD-ROM drive, a mobile device 26, an operating part 27, and a display driver 28, all of which are interconnected by a bus, such as Figure 17 shown. The image processing apparatus 1 is connected to a display 30 through a display driver 28 . The operation section 27 may include a keyboard and a mouse.

[0135] The central processing unit 21 mainly determines a color range, estimates color representation characteristics based on the obtained display state information, estimates color balance, and corrects image data based on the estimation. The above processing procedure will be described below.

[0136] The random access memory 22 serves as a job memory of the CPU 21 and temp...

Abstract

An even harmonic mixer comprises an antiparallel diode pair unit (11) including a first series unit in which a first diode (1a) and a first resistor (10a) are connected in series and a second series unit in which a second diode (1b) and a second resistor (10b) are connected in series, the first and second series units being connected in parallel so that the first and second diodes are opposite in polarity. <IMAGE>

Description

technical field [0001] The present invention relates to an image processing device for providing color image data to a remote client device for display by the client device, and more particularly to providing image data according to the color representation of the client device when displayed. Background technique [0002] With the recent development of Internet-related technologies, a technique of accessing a web server from a client device such as a personal computer to obtain color image data for display has become very common. Also, with the diversification of client devices, it is possible to access a web server even from a mobile phone or the like, so currently a portable phone equipped with a liquid crystal display capable of displaying a color image is often used to display image data. [0003] However, although there are various types of personal computer image display devices, the displayable color range of so-called "full-color display" will vary depending on the ...
