A photographing apparatus has two binocular stereoscopic modes. In two-take photography mode, a 3D image file is generated from left and right monocular images acquired by performing monocular photographing twice, and the 3D image file thus generated is recorded. In one-take photography mode, a 3D image file is generated from left and right monocular images acquired by performing binocular photographing once, and the 3D image file thus generated is recorded. When the 3D image file is recorded, a homogeneity tag is recorded in 3D metadata, as tag information of the header data portion of the 3D image file. The homogeneity tag is information about the homogeneity of the two monocular images and describes whether the two monocular images have been acquired in the one-take photography mode in which monocular images highly homogeneous are provided, or in the two-take photography mode in which monocular images not so homogeneous are provided.

An image quality/rate control portionconfirms whether a predictive code amount Ci is a target code amount Rt or less. When the predictive code amount Ci is the target code amount Rt or less, the predictive code amount Ci is output to a base layer coding portion. Then, a switchis turned off. When the predictive code amount Ci exceeds the target code amount Rt, the target code amount Rt is output to the base layer coding portion. Then, the switchis turned on and (predictive code amount Ci&#x2212;target code amount Rt) is output to an enhancement layer coding portion. A bufferstores coded data of the base layer coding portionand the enhancement layer coding portion In this manner, while performing fixed bit rate coding using a single transmission path, image quality of a moving image is made constant so as to prevent deterioration of image quality.

A stereoscopic image processing method capable of preventing occurrence of undesirable cutout of image when a stereoscopic combined image is printed out is provided. A stereoscopic combined image can be created and recorded using a digital still camera. This stereoscopic combined image is a single image formed by arranging a plurality of view-point images. At first, left view-point image data and right view-point image data are stored in a memory by performing photographing twice. Then, the data of the two images are arranged laterally into a single image. Through this processing, original stereoscopic combined image data is created. Padding areas (dummy areas) are added to the original stereoscopic combined image data at the upper and lower sides thereof. Namely, a processed image containing the original stereoscopic combined image is created.

An operation unit switches the operating mode between a 3D display output mode in which the images of the 3D image file are displayed as a stereoscopic images and a 2D display output mode in which one of the images of the 3D image file is displayed as an ordinary planar image. The 3D image file is composed of stereoscopic image data which represents a plurality of monocular images constituting a multi-ocular stereoscopic image and information which is added to the stereoscopic image data and which indicates that the data is stereoscopic data. In the 2D display output mode, a control unit makes an output unit display an image of the 3D image file read from a medium by a media reader and also display a mark on the same screen, indicating that the image displayed in the 2D display output mode is based on the 3D image file.

An image converter () creates image data in the format designated by the presence/absence of reduction and the presence/absence of joining. A 3D information creator () creates 3D information necessary for displaying the image as a 3-dimensional image by formatting the presence/absence of reduction, the presence/absence of joining and 2D select. A multiplexer () converts image data and 3D information in a predetermined format and outputs them to the outside. In this way, it is possible to make the image data for 3-dimensional display versatile and select an arbitrary viewpoint image efficiently.

A controller, based on the positional information of the display image, selects whether the 3-dimensional image data decoded by a decoderis displayed stereoscopically (in 3-dimensional display mode) or planarly (in 2-dimensional display mode) and gives notice of the selected display mode to a display portion. Specifically, the input positional information=display address is monitored, and if no temporal change occurs, namely if the displayed position of the image data does not change, 3-dimensional display mode is selected as the display mode. On the other hand, if there is a temporal change, namely if the displayed position of the image data varies by scrolling, 2-dimensional display mode is selected as the display mode. Thus, an image data display apparatus which can efficiently display image data on a display when display of 3-dimensional image data is scrolled is provided.

The image data is generated by interpolation and output to an image synthesizer (), in which a plurality of images data is synthesized in a form suitable for encoding. An encoder () encodes the image data and transfers it to a network (). The client () receives the encoded image data, decodes the data through a decoder () and outputs the decoded image data to an image processor (), where it is converted into a stereoscopic display format and displayed on a display unit (). The client () includes an input unit () for changing the viewpoint, and transmits the request information of viewpoint alternation to the network () by a request output unit ().

Disclosed herein is a 3-D image display unit that can be controlled flexibly to protect the user from eyestrain and operated easily. The 3-D image display unit includes measuring means for measuring a display time of a 3-D image, parallax adjusting means for instructing 3-D image forming means to adjust the parallax of the 3-D image. In the case where the 3-D image display time measured by the measuring means exceeds a predetermined time, the parallax adjusting means instructs the 3-D image forming means to reduce the parallax of the 3-D image to be formed, thereby the display means comes to display a 3-D image having a small parallax. The user can thus be protected from eyestrain.
