    • An accessory unit is mounted on an electronic camera, and a printer connects to the electronic camera via a SCSI terminal of the accessory unit. An image signal is captured from a CCD in response to the releasing operation, and the image signal is analog-to-digital converted before being transferred to the accessory unit. The accessory unit converts the image signal into RGB data suitable for the printer, and outputs the RGB data to the printer so that the captured image can be simultaneously with the image-capturing. Moreover, during sequential image-capturing, captured image data is sequentially stored in an uncompressed state in a frame memory of the accessory unit. After sequential image-capturing is completed, the image data is transferred to the camera in an order in which it is stored, and compressed. Further, a background image is recorded in a memory card in advance, and an image is composed from the background image and a captured image (or a reproduced image) in the accessory unit. The composite image data is then transferred to the printer.
    • 附件单元安装在电子照相机上,打印机通过附件单元的SCSI端子连接到电子照相机。 响应于释放操作,从CCD捕获图像信号,并且图像信号在被传送到附件单元之前被模数转换。 附件单元将图像信号转换成适合于打印机的RGB数据,并将RGB数据输出到打印机,使得捕获的图像可以与图像捕获同时进行。 此外,在顺序图像捕获期间,捕获的图像数据以未压缩状态顺序地存储在附件单元的帧存储器中。 在顺序图像捕获完成之后,图像数据按照其被存储的顺序被传送到相机并被压缩。 此外,预先将背景图像记录在存储卡中,并且从附件单元中的背景图像和捕获图像(或再现图像)构成图像。 然后将合成图像数据传送到打印机。

    • An image-capturing EV is obtained when a shutter button is half pressed, and whether to flash an electronic flash for a subject of low luminance is determined according to the image-capturing EV. If it is determined that the electronic flash should be flashed for the subject of low luminance, a white balance is adjusted according to an electronic flash light. If it is determined that the electronic flash should not be flashed for the subject of low luminance, color information relating to a plurality of areas divided from an entire image plane is acquired, and the number of areas belonging to a shade determination frame, which indicates a color distribution range corresponding to the shade, is found according to the acquired color information. Then, whether a type of the light source is the shade or the daylight is determined according to the obtained image-capturing EV and the number of areas belonging to the shade determination frame. The white balance is adjusted according to the determined type of the light source.
    • 当按下快门按钮时获得图像拍摄EV,并且根据图像拍摄EV确定是否为低亮度的被摄体拍摄电子闪光。 如果确定电子闪光灯应该以低亮度的对象闪光,则根据电子闪光灯调节白平衡。 如果确定对于低亮度的对象不应该闪烁电子闪光,则获取与从整个图像平面划分的多个区域有关的颜色信息,以及指示颜色确定框的区域的数量,其指示 根据获取的颜色信息找到与色调相对应的颜色分布范围。 然后,根据获得的图像拍摄EV和属于色度确定帧的区域的数量,确定光源的类型是阴影还是日光。 根据确定的光源类型调整白平衡。
