Patent ID: 7984346

Claim:
An integrated apparatus for testing image devices having a transmission side and a receiving side, comprising: an image level measuring means which is connected with a video signal path and receives a video signal from the transmission side of the image devices and detects a level of a corresponding video signal in the video signal path; an A/D converter which converts a signal detected by the image level measuring means into a digital signal provided by in accordance with a control signal; a communication test means which measures whether a data communication between the transmission side and the receiving side of the image devices is normally performed or not through a wired data transmission path; a text display circuit which is connectable with the video signal path between the transmission side and the receiving side and inserts a certain text data into a corresponding signal in accordance with a text control signal or detects an inserted text data provided to an image input circuit: a monitor which displays a text inserted or detected through the text display circuit or a text generated by the text control signal which controls the text display circuit; a key pad with which a worker or a user inputs a certain command or a text; and a main controller which checks and judges a certain error during a flow of a signal through the communication test circuit based on a user's request inputted through the key pad, evaluates a detection signal inputted through the A/D converter based on a previously set standard, and displays a result of a test and other test states on the monitor by controlling the text display circuit.
