摘要

PPROBLEM TO BE SOLVED: To provide a camera hand shake detecting device which can easily be incorporated in a small unit and to provide a camera hand shake detecting method and a hand shake influence relieving device relieving influence of hand shake with a simple constitution. PSOLUTION: A subtraction circuit 3 detects a differential value of each pixel between a plurality of frames obtained at a prescribed time interval and image data displayed by the differential value is obtained. A blocking part 4 divides image data displayed by the differential value into a plurality of blocks. A binarization part 5 binarizes the blocked data to "1" or "0" by a size of the differential value against a first reference value. An estimation part 6 counts the number of the blocks where the pixels whose values are "1" exist among a plurality of the blocks based on binarized image data. A hand shake judging part 7 judges presence or absence of hand shake according to whether the number of the counted blocks exceeds a prescribed second reference value or not. PCOPYRIGHT: (C)2004,JPO

要解决的问题：提供一种可以容易地并入到小单元中的照相机手抖动检测装置，并且提供一种以简单的构造来减轻手抖动的影响的照相机手抖动检测方法和手抖动影响缓解装置。。

解决方案：减法电路3检测以预定时间间隔获得的多个帧之间的每个像素的差分值，并且获得由该差分值显示的图像数据。块部分4将通过差分值显示的图像数据划分为多个块。二值化部分5通过将差分数据相对于第一参考值的大小二值化为“ 1”或“ 0”。估计部6基于二值化后的图像数据，对多个块中存在值为“ 1”的像素的块数进行计数。握手判断部7根据计数的块数是否超过规定的第二基准值来判断是否存在握手。
