A remote communication apparatus for receiving the image of a remote user captured by an imaging device to show the image to another user includes a zoom controller for controlling a zoom ratio defining the angle of view of the imaging device, and an estimator for estimating a distance between the imaging device and the remote user on the basis of the zoom ratio of the imaging device.

A motion vector searching apparatus to which a reference image, an object image and weight parameters for the reference image are inputted and searches a motion vector based thereon is provides. The motion vector searching apparatus includes an inverse weighting section that generates an inverse weighted object image by performing, on the object image using the weight parameter, a weighting inverse from a weighting performed on the reference image using the weight parameter; an image comparing section that compares the generated inverse weighted object image with the reference image to obtain a comparison value indicating a degree of approximation between the two images; and a determination section that determines an optimum motion vector from the comparison value.

A moving picture coding apparatus divides each frame of a moving picture into parts and assigns the parts to different coding units, which compressively code their respective parts. The coding process includes motion compensation with respect to a reference frame. Each coding unit has its own reference frame memory. To generate reference frame data, each coding unit receives, decodes, and decompresses the coded data generated by at least one other coding unit, as well as decompressing the data it has coded itself. Consequently, only ordinary coded data have to be passed between different coding units, which saves bandwidth and eliminates the need for special coding hardware and development and testing tools.
