Abstract:
PURPOSE: An infrared thermal imaging device and a method for processing an image signal using the same are provided to improve a contrast ratio by performing image processing in only a user interested areaon a specific area, thereby precisely displaying an image of the user interested image of a desired area. CONSTITUTION: An infrared detector(100) detects an infrared ray emitted from a thingsource. The infrared detector detects an image signal. An image signal processor(200) performs signal processing. The contrast ratio about of an image signal of a partial pixel area is improved through the signal processing. An image output unit(300) outputs the image signal in on which signal processing is performed.
Abstract:
PURPOSE: A simulation image projection device and a detection simulation system using the same are provided to exclude a cooling configuration which is normally applied to sensing devices, thereby improving the convenience of management and costs due to an overall infrared simulation test. CONSTITUTION: A simulation image projection device (100) includes a simulation image projection device (110) and a sensing device (120). The simulation image projection device includes an image generator (112), an LCD beam projector (114), a collimator (116), and a sync separator (118). The image generator generates image signals for transmission and transmits the same to the LCD beam projector. The LCD beam projector generate images for transmission corresponding to the image signals for transmission and makes beams corresponding to the images for transmission incident to the collimator. The collimator transmits the beams having frequencies of a visible band among the beams incident from the LCD beam projector and projects the transmitted beams to the sensing device. The sync separator separates synchronizing signals from the image signals for transmission and transmits the same to the sensing device. The sensing device includes a detection sensor (122) and a signal processor (124). The sensing sensor senses visible rays which are incident from the LCD beam projector by using the synchronizing signals transmitted from the simulation projection device and detects the visible rays. The signal processor processes the image signals sensed by the sensing sensor.
