KR100248039B1 - Video camera apparatus with the function of shaking compensation - Google Patents

Abstract

As described above, the present invention is composed of a screen comparing means, a change amount detecting means, and a timing control means to compensate for the shaking of the image caused by the movement of the subject and the user. In particular, the image recorded by detecting and correcting the shake amount is recorded. The present invention relates to a camcorder image stabilization device for providing a clear picture during playback.

Description

Video camera device with image stabilization

1 is a screen configuration diagram according to the present invention,

2 is a block diagram of the present invention,

3 is a timing diagram according to the operation of the present invention.

The present invention relates to a video camera apparatus having a function of compensating for shaking of an image due to a movement of a subject and a user, and more particularly, a video camera apparatus for providing a clear screen when playing a recorded image by detecting and compensating for the amount of shaking. It is about.

Camcorders and video recording apparatuses that are not equipped with the conventional image compensating apparatus are shaken to record the image recorded by the movement of the subject and the user's movement at the time of shooting and because of this, a clear screen is not provided when the recorded image is reproduced. There was a problem to use a fixing device such as.

Accordingly, an object of the present invention is to provide an image signal picked up from a conventional image pickup means as a TV signal in a signal processing means and to have a video compensation device for compensating for a shaken screen in a video camera apparatus for recording on a recording medium. By compensating and recording, the present invention provides a clear screen during image playback.

The video camera device of the present invention according to the above object allows the screen to be moved by vertical and horizontal gate timing signals at predetermined intervals in the vertical and horizontal directions with the outer surface of the CCD region in the actual CCD region so as to be able to compare the variation of the screen. And a change amount detection point for detecting a change amount changed by the movement of the user and the subject on the formed screen to detect the change amount changed by the movement of the user and the subject, and detect the change amount by the changed detection amount. Screen comparison means for comparing the formed image signal changed by the movement of the user and the subject within the reference screen, and shaking the motion of the screen to detect the amount of motion between the screen by comparing the processed image signal in units of screens Detection means according to the detected shake amount It consists of a timing control means for compensating for horizontal and vertical timing of the unit.

An embodiment of the video camera device of the present invention according to the above configuration will be described in detail with reference to FIGS. 1, 2, and 3.

1 is a diagram showing the relationship between a real screen set in the original CCD region and a clock for forming horizontal and vertical gate timing clocks and change detection points for carrying out the present invention, and FIG. 2 is a configuration of a video camera device according to the present invention. 3 is a timing diagram according to an operation.

In FIG. 1, FIG. 2, and FIG. 3, it consists of a CCD (solid-state image sensor) etc. which convert the image of the subject on the real screen 12 set in the original CCD area 11 into an electrical signal. The signal generated by the image pickup device 21 is signal processed by the signal processing means 22 and the processed video signal is recorded in the recording device 23. The recorded video signal is formed between the signal processing means and the recording apparatus, and is formed by the horizontal and vertical movement amount detecting point clocks 32 and 36 in the screen comparing means 24 for comparing the current input screen with the previous screen. The two change amounts 34 and 38 of the horizontal plane and the vertical plane of the compared screen are detected by the change amount detecting means 25 for detecting the change amount. The detected amount of change is input to timing control means 26 for controlling the horizontal and vertical gate timings 31 and 35 for displaying one screen area according to the present invention, and the timing control means controls the movement of the user and the subject. Thereby, two timing clocks 39 and 40 are generated, which are compensated by the amount of change. By the two compensated timing clocks, the next screen inputted to the signal processing means is matched with the previous screen, and the compensated screen is driven as a reference screen and compared with the next input screen.

As described above, the present invention comprises a screen comparing means, a change amount detecting means, and a timing control means, and thus, a remarkable effect of providing a clear screen when reproducing the recorded image by detecting and compensating for the shake amount of the image caused by the movement of the subject and the user. There is.
