摘要： A camera having a real-image viewfinder incorporating an optical finder system having the functions of an optical system for automatical focusing or an optical system for automatic exposure. The optical finder system comprises an objective lens having a positive power, an eyepiece, and an optical system such as porro mirror, disposed between the objective lens and the eyepiece and comprising a plurality of mirrors and/or a prism. Some of the mirrors a semitransparent mirrors capable of dividing the incident light for two optical paths. One part of the incident light is transmitted to the eyepiece and the other part of the incident light is transmitted to light receiving elements, which are disposed in substantially conjugate planes with respect to the focal plane of the objective lens, respectively for distance measurement and light measurement.

摘要： A camera accessory is provided which allows a camera to photograph in a pseudo focal length photographing mode. In the pseudo focal length photographing mode, a portion of an image recorded onto a film is reproduced on a print with larger enlargement than a normal image. Therefore, a print can be obtained as if it has been printed from an image recorded on a film which had been photographed by an objective lens having a focal length longer than the actual focal length of the objective lens used. Thus, according to the camera accessory, photographing in the pseudo focal length photographing mode can be possible if used in a camera which is originally incapable of the pseudo focal length photographing mode.
摘要翻译：提供了一种照相机附件，其允许相机以伪焦距拍摄模式拍摄。在伪焦距拍摄模式中，记录在胶片上的图像的一部分在比普通图像更大的放大的打印上再现。因此，可以从被记录在具有比所使用的物镜的实际焦距长的焦距的物镜拍摄的胶片上的图像中进行打印。因此，根据相机附件，如果在原始不具有伪焦距拍摄模式的相机中使用，则在伪焦距拍摄模式下进行拍摄是可能的。

摘要： By constructing a plurality of packs from a first packet including first data having a high bit rate and a second packet including second data having a low bit rate, when the first data and the second data are multiplexed, it is first detected whether a data length of second data is smaller than a maximum data length of second packet or not. Subsequently, when it is detected that the data length of second data is smaller than the maximum data length of second packet, one pack is constructed by a redundancy data packet including redundancy data of a data length which is equal to a difference between the maximum data length of second packet and the data length of second data and the second packet.
