There is provided parallax correction means for correcting a parallax for each area calculated by parallax calculation means in accordance with the magnitude of a motion vector for the area detected by motion vector detection means in order to prevent the three-dimensional effect of a conversion video from greatly differing depending on an input video when the MTD method and the CID method are simultaneously used. When a depth estimate is converted into a parallax, the depth estimate is subjected to distance scale conversion in order to suppress the distortion of the conversion image, to find a tentative target phase for each parallax calculation area, and a dynamic range in which a phase difference between the parallax calculation areas is within a distortion allowable range is searched for and is subjected to distance scale conversion, to find a tentative target phase, which operations are repeated.

An abnormality detection apparatus for detecting an event where a monitored object in a room has lapsed into an abnormal state. The apparatus includes an image pickup system for picking up an image of a scene in the room, and feature-quantity extraction devices for extracting an image feature quantity from the image picked up by the image pickup devices. The apparatus also includes judgment devices for determining whether the monitored object in the room has lapsed into the abnormal state or not based on the time-variations of the image feature quantity extracted by the feature-quantity extraction devices, and outputting an alarm that responds to the determination of the occurrence of the abnormal state.

Abnormality detection apparatus and method

A video camera including an optical zoom mechanism and an electronic zoom circuit which is used at a time that a magnification of the optical zoom mechanism reaches a limit thereof or a time that a picture stabilization is to be performed. If a magnification of an electronic zoom is smaller than &ldquo;1.2&rdquo; at a timing when a stabilization switch is turned-on, a microcomputer not only gradually increases an electronic zoom magnification up to &ldquo;1.2&rdquo; and but also gradually decreases an optical zoom magnification. If the magnification of the electronic zoom is smaller than &ldquo;1.2&rdquo; at a timing when the stabilization switch is turned-off, the microcomputer gradually decreases the electronic zoom magnification to an electronic zoom magnification of a timing when the stabilization switch is turned-on, and gradually increases the optical zoom magnification. Thus, a sudden change of a view angle due to a change of the electronic zoom magnification is suppressed.

A method of converting two-dimensional images into three-dimensional images by producing from a two-dimensional image signal a first image signal which forms a basis and a second image signal delayed by a predetermined number of fields from the first image signal and taking one of the signals as a left eye image signal and the other as a right eye image signal. It is judged whether or not a scene represented by the two-dimensional image signal is changed. When it is judged that the scene is changed, delay indicating how many fields are there from a field corresponding to the first image signal to a field corresponding to the second image signal is set to a predetermined value, for example, zero.

Method of converting two-dimensional images into three-dimensional images

A left eye image signal and a right eye image signal which constitute a three-dimensional image are produced from a two-dimensional image signal. The horizontal phase of the produced left eye image signal is shifted, and the horizontal phase of the produced right eye image signal is shifted. Character signals are respectively mixed with the left eye image signal and the right eye image signal. A composite image comprising the three-dimensional image and the character signal is displayed on the basis of the left eye image signal with which the character signal is mixed and the right eye image signal with which the character signal is mixed.

Three-dimensional image display device

In the present invention, two-dimensional images are converted into three-dimensional images by producing from a two-dimensional image signal a main image signal and a sub-image signal delayed from the main image signal. A field delay indicating how many fields are there from a field corresponding to the main image signal to a field corresponding to the sub-image signal is changed depending on the speed of the horizontal movement of the main image signal. The upper limit of the field delay is determined on the basis of vertical components of motion vectors detected from the main image signal. The field delay is so determined that it is not more than the determined upper limit.

A stereo-graphic apparatus has first and second imaging devices to provide a first image and a second image, respectively. The first and the second imaging device are spaced from each other to define a predetermined convergence angle. A distance detecting apparatus detects distance from the first and the second imaging device to an object for imaging. A first electric zooming apparatus receives a signal from the first imaging device and extracts image data of a predetermined area from the first image. A second electric zooming apparatus receives a signal from the second imaging device and extracts image data of a predetermined area of image. A control device controls the extraction of image data according to the distance information. According to the distance information, the extracting area is moved so that the focused object is located on the center of each of the provided images. As a result, the convergence angel is substantially changed according to the distance between the object and the imaging device.

The present invention relates to a method of judging the back-and-forth positional relationship between subjects. Amounts of horizontal movement of the subjects which are detected for detecting areas set in an image area constituting a 2D image are compared after being assigned plus or minus signs depending on the direction of the movement, thereby to classify all the detecting areas into two types of detecting areas in such a manner that the detecting areas where a relatively large amount of horizontal movement is detected are taken as first detecting areas, while the detecting areas where a relatively small amount of horizontal movement is detected are taken as second detecting areas. A target area is set in a peripheral portion in the image area, to judge which of the total number of first detecting areas existing in the target area and the total number of second detecting areas existing in the target area is larger. It is judged that the subjects in all the detecting areas whose total number existing in the target area is judged to be larger are positioned behind the subjects in all the detecting areas whose total number existing in the target area is judged to be smaller.

The present invention relates to a method of converting 2D images into 3D images by producing from a 2D image signal a main image signal and a sub-image signal delayed from the main image signal. In the present invention, a temporary field delay from the main image signal to the sub-image signal is found on the basis of data related to the movement in the current field of the main image signal (a first step). A target field delay is then found on the basis of the temporary field delay found in the first step (a second step). A true field delay used in the succeeding field is found on the basis of the target field delay found in the second step and the true field delay used in the current field (a third step).
