    • Object brightness color information is recorded on a recording medium such as a photographic film at the time of taking an object image. In making a photoprint, the brightness information or color information is read from the photographic film, and is used for the calculation of a print exposure amount. The brightness information is used to convert photometric values at respective measurement points within a frame into brightness information. The color information is used to obtain the actual color of an object at respective measurement points. In one embodiment, effective measurement points are determined in accordance with the value of brightness information at respective measurement points, and characteristic values to be used for the calculation of a print exposure amount are derived by using the effective measurement points. In another embodiment, scene type is judged in accordance with the maximum value of the brightness information, and the print exposure amount is determined in accordance with the judged scene type. In yet another embodiment, scene type information is recorded on a photographic film, the scene type being discriminated in accordance with brightness values obtained by measuring the scene at respective divisional areas. To make a photoprint, the scene type information is read to determine a print exposure amount for the discriminated scene. In still another embodiment, the information representative of luminance values obtained through divisional area photometry, and an average luminance of a scene is recorded in a photographic film. A print exposure amount is determined by using the recorded luminance difference.
    • 对象亮度颜色信息在拍摄对象图像时被记录在诸如摄影胶片的记录介质上。 在进行照相印刷时,从摄影胶片读取亮度信息或颜色信息,并用于计算打印曝光量。 亮度信息用于将帧内各测量点的测光值转换为亮度信息。 颜色信息用于在各测量点获得物体的实际颜色。 在一个实施例中,根据各测量点处的亮度信息值来确定有效测量点,并且通过使用有效测量点导出用于计算打印曝光量的特征值。 在另一实施例中,根据亮度信息的最大值判断场景类型,并且根据所判断的场景类型来确定打印曝光量。 在另一个实施例中,场景类型信息被记录在摄影胶片上,场景类型根据通过测量各个分区的场景而获得的亮度值进行区分。 为了进行照相打印,读取场景类型信息以确定用于被识别场景的打印曝光量。 在另一个实施例中,表示通过分区光度测量获得的亮度值的信息和场景的平均亮度被记录在摄影胶片中。 通过使用记录的亮度差来确定打印曝光量。

    • A recording medium such as a photographic film is recorded with an image of a principal object and distance information of the principal object. The distance information is read during a printing operation for calculating a print exposure amount. In calculating the print exposure amount, a scene of an object image is discriminated in accordance with the object distance, and a calculating equation, which is different for each discriminated scene, is selected for use. Finer discrimination may be conducted by using flash emission data and object brightness data in addition to the distance information. Effective measurement points may be selected from all measurement points within a frame by taking the distance information into consideration, to calculate a print exposure amount by using the selected effective measurement points. A print exposure amount also may be calculated so as to use the distance information of a background image at each divisional frame area, together with the distance information of a principal object image. A characteristic value for each divisional frame area to be used for the calculation is weighted in accordance with a difference between the principal image distance and background image distance.
    • 用主体的图像和主要对象的距离信息记录诸如摄影胶片的记录介质。 在用于计算打印曝光量的打印操作期间读取距离信息。 在计算打印曝光量时,根据对象距离来辨别对象图像的场景,并且选择不同于每个被辨别场景的计算方程。 除了距离信息之外,还可以通过使用闪光发射数据和对象亮度数据来进行更好的辨别。 可以通过考虑距离信息来选择在帧内的所有测量点的有效测量点,以通过使用所选择的有效测量点来计算打印曝光量。 还可以计算打印曝光量,以便与主要对象图像的距离信息一起使用每个分割帧区域的背景图像的距离信息。 根据主图像距离和背景图像距离之间的差,对用于计算的每个分割帧区域的特征值进行加权。

    • A camera comprises an exposure frame for defining an exposure aperture in the camera body, an automatic film winding device incorporated in the camera body, and a light emitting element disposed at the exposure frame. The light emitting element is controlled to emit light to which a loaded film is exposed as the film is advanced by the automatic film winding device. The film provided by the camera, after development, shows a visible image of various line marks produced by the light emitting element which indicate that the film or a portion of frames on the film have been exposed under a certain mode of operation of the camera. The line mark is detected when picture images on the film are magnetically recorded on a magnetic sheet. The magnetic sheet is transferred to a reproducing apparatus in order to display the picture image on a TV screen in one of a variety of ways according to the line marks.
