PURPOSE: A temperature bad condition test system and a frost blocking window included in the same are provided to test the performance of an electronic appliance under the temperature of bad conditions such as high temperature or low temperature. CONSTITUTION: A chamber controls temperature of inside. A frost blocking window is installed at one side of the chamber. The frost blocking window comprises a main chassis(210), a penetrated hole(215), a front glass(221), and a back glass(223). The main chassis forms a window frame. A first coupling part and a second coupling part are formed in the inner surface of the main chassis. The front glass and the back glass are fixed to the first coupling part and the second coupling part of the main chassis while maintaining regular interval each other.

PURPOSE: A test chart set and a test system for testing a wide-area backlight correcting function of a digital photographing device are provided to perform a test of a wide-area backlight correcting function of an image photographing device in a quite bright surrounding background such as a case being instantaneously exposed to strong and bright lights. CONSTITUTION: A test chart set for testing a wide-area backlight correcting function of a digital photographing device comprises a normal test chart(100), a high brightness test chart(200), and a low brightness test chart(300). The normal test chart comprises a normal basis and normal annulus patterns. The normal basis is colored with colors of medium-brightness. A plurality of normal annulus patterns in which colors having gradual brightness are colored is arranged in an annulus shape in the normal annulus pattern. The high brightness test chart comprises a high brightness basis and high brightness annulus patterns. The high brightness basis is colored with colors having the brightness brighter than the medium-brightness. The low brightness test chart comprises a low brightness basis and low brightness annulus patterns.

PURPOSE: A camera test system for testing shading and color balancing is provided to enable test at various color temperatures and angels like practical circumstance using a color temperature filter and a lamp. CONSTITUTION: A camera test system for testing shading and color balancing comprises an integrated booth(100), an irradiation device(300), and a setter lens(SLZ). The integrated booth forms a dark room inside. The irradiation device is installed inside the integrated booth. The irradiation device comprises a color temperature filter(FTC) and a lamp(LP). The color temperature filter transmits the light ray of specific color temperature. The lamp emits the light ray of the specific color through the color temperature filter.
Abstract:
PURPOSE: A semiconductor package test system is provided to effectively check the presence of a semiconductor package in a test socket. CONSTITUTION: A semiconductor package test system comprises a test block(100), a photographing block(200), an image storing block(300), and an analyzing and determining block(400). The test block comprises a test tray and a package setting unit. The test tray comprises a plurality of sockets in which a semiconductor package is accepted. The package setting unit loads the semiconductor package in the test tray. The test block unloads the semiconductor package from the test tray. The photographing block takes a picture of the plurality of sockets of the test tray and creates a photographing image. The image storing block stores a reference image. The analyzing and determining block compares similarity of the reference image and the photographing image and creates existence information showing accepting state of the semiconductor package in a test socket. [Reference numerals] (100) Test block; (110) Test tray; (120) Package setting unit; (200) Photographing block; (300) Image storing block; (400) Analyzing and determining block; (500) Feedback block
Abstract:
PURPOSE: A display test system in which an unfavorable temperature condition test is facilitated is provided to perform an unfavorable temperature condition test of a display in the state that a test operator is not exposed to an extreme temperature environment. CONSTITUTION: A display test system in which an unfavorable temperature condition test is facilitated comprises a chamber(100), a selectively filtering membrane(200), a measuring device(300). Regulating temperature in the inside of the chamber is possible and a display setting member(110) is installed in the inside of the chamber. The display setting member sets a test display(TDS) being tested, thereby controlling the test display to generate images. The selectively filtering membrane is formed in one side of the chamber and a plurality of transmitting windows(WTR) are arranged in the selectively filtering membrane. The plurality of penetration windows transmits the images of the test display to the outside of the chamber. The measuring device is installed in the outside of the chamber and measures the images of the test play being transmitted through the transmitting window of the selectively filtering membrane.
