    • A camera having a learning function which automatically sets data for current photographing in accordance with a tendency of data set in the past (learned data) and takes a photograph in accordance with the data thus set. The camera comprises a light measuring section for measuring a brightness of an object for the photographing, a calculating section for calculating an exposure control value in accordance with the brightness of the object for the photographing, a first setting section for manually setting first data with which the exposure control value is to be corrected, a first correcting section for correcting the exposure control value in accordance with the first data, a second setting section for setting second data in accordance with first data set in the past by the first setting section, a second correcting section for correcting the exposure control value in accordance with the second data, and an exposure controlling section for executing exposure control in accordance with the exposure control value corrected by the first correcting section or the second correcting section.
    • 具有学习功能的相机,其根据过去设置的数据的趋势(学习数据)自动设置当前拍摄的数据,并根据如此设置的数据拍摄照片。 相机包括用于测量拍摄对象的亮度的光测量部分,用于根据拍摄对象的亮度计算曝光控制值的计算部分,用于手动设置第一数据的第一设置部分, 要修正曝光控制值,用于根据第一数据校正曝光控制值的第一校正部分,用于根据第一设置部分过去设置的第一数据设置第二数据的第二设置部分, 第二校正部分,用于根据第二数据校正曝光控制值;以及曝光控制部分,用于根据由第一校正部分或第二校正部分校正的曝光控制值执行曝光控制。
