Abstract

PROBLEM TO BE SOLVED: To accurately correct the image jitter by discriminating whether the movement of a camcorder is due to a camera shake or the one intended by a photographer. SOLUTION: A vertical gyrosensor 1 detects an angular velocity corresponding to the extent of vertical movement of the camcorder to generate a vertical movement extent detection signal S1. A horizontal gyrosensor 2 detects an angular speed corresponding to the extent of horizontal movement of the camcorder to generate a horizontal movement extent detection signal S2. A comparator 3 compares the signal S1 with a vertical reference voltage V1 and amplifiers the signal S1 to output a vertical jitter detection signal S3. A comparator 4 compares the signal S2 with a horizontal reference voltage V2 and amplifiers this signal S2 to output a horizontal jitter detection signal S4. A/D converters 21 and 22 perform A/D conversion of signals S3 and S4. A jitter correction control part 23 uses vertical and horizontal jitter detection signals subjected to A/D conversion to decide whether the movement of the camcorder is caused by a camera shake or is intended by the photographer, and an image processing part 30 is controlled in accordance with the decision result.

えない。Generally, the output signal of the gyro sensor in response to the periodical movement of the camcorder has a low frequency as shown in FIG. The output signal of the gyro sensor, on the other hand, has a large change in the magnitude of the output signal at the start portion and the end portion of the movement of the camcorder as shown in FIG. Further, the output signal of the gyro sensor in response to the intentional movement of the camcorder has a high frequency only at the end portion of the movement of the camcorder as shown in (C). When the camcorder intentionally moves by the photographer and the camcorder moves due to camera shake, a typical output waveform of the gyro sensor has a symmetrical shape as shown in (D). At this time, the same method is applied to determine whether the movement of the camcorder is a camera shake or the intention of the photographer by using the output signals of the horizontal gyro sensor and the vertical gyro sensor. Further, the movement direction of the gyro sensor does not affect whether the movement of the camcorder is a camera shake or the intention of the photographer.

A method of correcting an image jitter of a camcorder according to the present invention will be described in detail with reference to FIGS. First, the vertical and horizontal movement amounts are detected through the movement amount detection unit 10 shown in FIG. That is, the vertical movement amount detection signal S1 generated through the vertical gyro sensor 1 and the vertical reference voltage V1 are compared and amplified by the comparator 3 to generate the vertical jitter detection signal S3, and the horizontal movement generated through the horizontal gyro sensor 2 is generated. Quantity detection signal S2 and horizontal reference voltage V
The horizontal jitter detection signal S4 is generated by comparing and amplifying 2 through the comparator 4. The vertical and horizontal jitter detection signals S3 and S4 thus generated indicate the vertical and horizontal movement amounts of the camcorder (step 100).

After the vertical and horizontal jitter detection signals S3 and S4 are converted into digital signals through the analog-digital converters 21 and 22, the jitter correction control unit 23 detects the frequency using the digitally converted values ( 110).

することになる（１４０段階）。Next, the jitter correction control unit 23 determines whether the detected frequency is within the range of the correction frequency. On this occasion,
It is desirable that the correction frequency range be 0 to 29 hz.
At this time, it is preferable to remove a frequency component of 30 hz or more by using a hardware filter or a programmed soft filter in the jitter correction controller 23 (step 120). If it is determined that the frequency of the detection signal is out of the predetermined frequency range due to the intentional movement of the camcorder, whether the change in the magnitude of the vertical and horizontal jitter detection signals is within the predetermined frequency range due to the intentional movement of the camcorder. To judge. When there is a motion of the camcorder due to a momentary impact, it is difficult to judge whether the motion of the camcorder is intentional by using the frequency. Therefore,
In this case, whether or not the camcorder is intentionally moving is determined based on the change in the magnitude of the vertical and horizontal jitter detection signals (step 140).

を判断する（１６０段階）。If it is determined in step 140 that the change in size is not caused by the intentional movement of the camcorder, image jitter due to camera shake is corrected (step 150).
If it is determined in step 120 that the frequencies of the vertical and horizontal jitter detection signals are out of the correction frequency range, it is determined whether they are within the correction range. In step 130, it is determined that the frequencies of the vertical and horizontal jitter detection signals are within a predetermined frequency range due to the intentional movement of the camcorder, or in step 140, the change in the magnitude is the intention of the camcorder. If it is determined that the vertical and horizontal jitter detection signals are within the correctable range, it is determined (step 160).

できないほどに決定される（１７０段階）。If it is determined in step 160 that the correction is possible, the image jitter due to camera shake is corrected by performing step 150. On the other hand, if it is determined that the correction cannot be performed in step 160, the image jitter correction is stopped and the centering operation is performed. At this time, the centering operation means an operation for returning the image data to the reference value (the value in the middle of the screen) because the image data in the state where the correction is stopped has the maximum value of the correctable range. At this time, the amount and speed of retrieving the image data at the center are determined by an internal program of the jitter correction control unit 23 so that they cannot be recognized by a person (step 170).
