In general, when adjusting the camera mode of the camcorder in the production line, the adjuster manually adjusts the camera to a certain state by monitoring the monitor or measuring device while photographing the test pattern chart corresponding to each adjustment.

That is, FIG. 1 schematically shows a camera adjustment mode adjustment system of such a conventional camcorder, where the camcorder is input through the lens 2 and the CCD 3 while imaging the test pattern 1 at a certain distance. The electrical signal is output to the camera signal through a variety of signal processing in the signal processing and adjusting section 4, the adjuster through the signal processing and adjusting section 4 so as to be in the proper state for each adjustment while watching the monitor or measuring instrument Manually adjusted

Therefore, in the conventional technique as described above, the final output signal processed may vary according to the subject and the imaging state, and thus the accuracy of the adjustment is reduced by the adjustment due to the wrong photographing state, and the adjustment state is changed because the person confirms the adjustment completion state. It can be inaccurate. In addition, since the adjustment must be performed manually by a person, inconvenience has been accompanied, and there is a problem that the adjustment takes a lot of time by manual adjustment.

SUMMARY OF THE INVENTION The present invention has been made to solve this problem, and an object of the present invention is to store test pattern data necessary for each adjustment so as to automatically adjust using this data during adjustment, thereby reducing the misadjustment and adjustment time by manual adjustment.

The test pattern data output unit and the reference data output unit according to a key input of Automatic adjustment of the camera adjustment mode of the camcorder comprising a control unit for controlling the switching of the output unit and the switching unit, and the control unit controlling the signal processing unit and the control unit until the output of the comparison unit of the comparator compares the output of the signal processing unit and the reference data output unit. Is in the device.

The present invention also provides a first step of switching to an adjustment mode when an adjustment selection key for selecting various adjustment modes of the camera is input, and outputting test pattern data corresponding to the adjustment mode selected and switched in the first step. In addition, a second step of signal processing with the adjustment data corresponding to the adjustment mode, a third step of comparing the signal processing output of the second step and the reference data in the case of fine adjustment in each adjustment mode, and the third step If the two values match, the camera adjustment mode automatic adjustment device of the camcorder comprises the fourth step of setting the adjustment data at that time as the final data.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a camera adjustment mode automatic adjustment device of a camcorder according to the present invention, and includes a key input unit 10 having an adjustment selection key for selecting each adjustment mode, and the key input unit 10. Selective switching of the test pattern data output unit 20, the CCD unit 12 output, and the output of the test pattern data output unit 20, which output test pattern data corresponding to each adjustment mode when the adjustment selection key is input from A signal processing and adjusting unit for signal processing the switching unit 30 and the imaging data from the CCD unit 12 and for processing the adjustment data corresponding to the test pattern data output from the test pattern data output unit 20 ( 40), comparing the reference data output unit 50 for outputting the reference data corresponding to each adjustment mode with the output of the signal processing and adjustment unit 40 and the output of the reference data output unit 50; 60 and the test pattern data output unit 20 to control the test pattern data output unit 20 according to the key input of the key input unit 10 to output test pattern data corresponding to the key input. Control the switching of the < RTI ID = 0.0 >), < / RTI > and output the reference data corresponding to the key input from the reference data output unit 50, and the signal output final output of the comparison result signal processing and adjusting unit 30 The control unit 70 controls the signal processing and adjusting unit 30 until the reference data of the reference data output unit 50 matches.

According to the present invention configured as described above, when the camera adjustment mode is selected by inputting the adjustment selection key of the key input unit 10, the controller 70 controls the test pattern data output unit 20 to be selected by the key input unit 10. Output test pattern data corresponding to the adjustment mode. Here, examples of the adjustment mode include color reproducibility adjustment, white balance adjustment, and the like.

The test pattern data stored in the test pattern data output unit 20 is data considering spectroscopic characteristics such as a lens and a CCD used in a camcorder to be adjusted.

On the other hand, the control unit 70 at the same time as the control of the test pattern data output of the test pattern data output unit 20 so that the switching unit 30 is switched to the terminal (b) from the test pattern data output unit 20 The test pattern data to be output is applied to the signal processing and adjusting unit 40, and at the same time, the signal processing and adjusting unit 40 is controlled to adjust corresponding to the test pattern data output from the test pattern data output unit 20. Signal to data.

In addition, the controller 70 controls the reference data output unit 50 to output reference data corresponding to the adjustment mode selected through the key input unit 10.

Accordingly, the comparison unit 60 compares the output data of the signal processing and adjustment unit 40 with the reference data of the reference data output unit 50, and the control unit 70 compares the result of the comparison unit 60. The camera signal is finally output by controlling the signal processing and adjusting unit 40 until the output data of the signal processing and adjusting unit 40 and the reference data of the reference data output unit 50 match. Set the value to the positive adjustment value of the adjustment mode.

On the other hand, the present invention has the meaning of the adjustment of the signal processing and adjusting unit 40 only when the lens unit 11 and the CCD unit 12 has been optimally adjusted. Because the lens unit 11 and the CCD unit 12, which are before the signal processing, receive light and perform a photoelectric conversion, that is, an electric signal. If only the signal processing and adjusting unit 40 is accurately adjusted, the lens unit ( 11) and the CCD 12 are inaccurate when viewed as a whole camera.

Therefore, if a manufacturer experiments with lens performance and CCD performance and presents experimental values, the test pattern data of the test pattern data output unit 20 according to the present invention is also output as data corresponding to the experimental values. Adjusting only the adjuster is equivalent to adjusting the entire camera.

Meanwhile, the present invention will be described with reference to the flowchart of FIG. 3 as follows.

First, if it is determined whether the adjustment selection key is input (S1), and it is determined that there is an input of the adjustment selection key, the control unit 70 switches the switching unit 30 to switch the current mode to the adjustment mode (S2).

Then, the test pattern data output unit 20 is controlled to output the test pattern data A corresponding to the mode selected by the adjustment selection key so as to be signal processed to the corresponding adjustment data B (S3 and S4).

Then, the data C signal-processed and output in step S4 is compared with the reference data D corresponding to the adjustment mode selected by the input of the adjustment selection key (S5).

Then, it is determined whether the two values (C) and (D) coincide, and the signal processing and adjusting unit 40 adjusts and adjusts the data B of the signal processing and adjusting unit 40 when the signal is matched until it matches. Set to normal data (S6-S8).

As described above, the present invention stores data necessary for each adjustment of the camera mode, and automatically adjusts using this data when each adjustment mode is selected, thereby preventing misadjustment caused by errors caused by manual adjustment and the surrounding environment. In addition, it is possible to reduce the inconvenience of adjusting and manually adjusting the adjustment time.
