    • An image pickup apparatus includes an automatic exposure controller automatically controls ISO sensitivity in response to the output signal of an exposure metering circuit, and controls the exposure so that exposure setting is determined based on the brightness values of both the central photometry area and the remaining photometry area of an imaging frame. The automatic exposure controller controls the exposure setting so that when the ISO sensitivity is set to its higher value, the weighting factor of the central photometry area is higher than that of the remaining photometry area. The automatic exposure controller further determines whether or not a light source is behind an object, and, if it is the case, reduces the adjusted exposure setting so as to increase the amount of light incident on the image pickup apparatus.
    • 图像拾取装置包括自动曝光控制器,以响应于曝光计量电路的输出信号自动控制ISO感光度,并且控制曝光,使得基于中央测光区域和剩余测光学的亮度值确定曝光设置 成像框架的区域。 自动曝光控制器控制曝光设置,使得当ISO感光度设置为更高的值时,中央测光区域的加权系数高于其余测光区域的加权系数。 自动曝光控制器还确定光源是否在物体后面,并且如果是这种情况,则减小调整的曝光设置以增加入射在图像拾取装置上的光量。

    • In a system in which an editing server and a plurality of client computers are capable of communicating with one another, an edited image can be generated by the plurality of client computers.When image data is transmitted from the image server to the client computer, the resolution of image data to be transmitted is reduced in correspondence with the resolution of a monitor display device connected to the client computer. Further, the number of colors of an image represented by the image data is decreased in correspondence with the number of colors which can be displayed on the monitor display device. The data quantity of the image data to be transmitted is reduced, so that time required to transmit the image data is shortened.A client computer and a main image server are connected to each other. A user image to be synthesized on a template image is read in the client computer. Image data representing the template image used for the image synthesis and image data representing a mask image are transmitted from the main image server to the client computer. In the client computer, image synthesis processing is performed. Image data representing an area required for image synthesis of the user image used for the image synthesis is extracted. The extracted user image data and synthesis information required for the synthesis are transmitted from the client computer to the main image server. In the main image server, a composite image is printed.
    • 在编辑服务器和多个客户端计算机能够彼此通信的系统中,可以由多个客户端计算机生成编辑的图像。 当图像数据从图像服务器发送到客户端计算机时,与连接到客户端计算机的监视器显示装置的分辨率相对应地减少要发送的图像数据的分辨率。 此外,由图像数据表示的图像的颜色数量与可以在监视器显示装置上显示的颜色数量相对应地减少。 减少要发送的图像数据的数据量,从而缩短发送图像数据所需的时间。 客户端计算机和主映像服务器相互连接。 在客户端计算机中读取要在模板图像上合成的用户图像。 表示用于图像合成的模板图像的图像数据和表示掩模图像的图像数据从主图像服务器发送到客户端计算机。 在客户端计算机中,执行图像合成处理。 提取表示用于图像合成的用户图像的图像合成所需的区域的图像数据。 所提取的用户图像数据和合成所需的合成信息从客户计算机发送到主图像服务器。 在主映像服务器中,打印合成图像。
