    • A digital camera having a plurality of adjustable memory card fullness icons to visually indicate the amount of memory space that is available for storage in a plurality of corresponding removable memory cards insertable into the digital camera is disclosed. The digital camera includes an arrangement for capturing and digitizing image data, a display, and a processor for constructing the memory card fullness icon on the display. Each memory card fullness icon includes an inner portion that can be adjusted to graphically display the relative amount of memory space that is available for storage in its corresponding removable memory card. The digital camera further includes circuitry for transferring the digitized image data into a selected removable memory card. The processor determines the relative amount of available memory space in the selected memory card and modifies the adjustable inner portion of the memory card fullness icon on the display to visually indicate in graphic format the present relative amount of available memory space in the selected memory card.
    • 公开了具有多个可调节存储卡充满度图标的数字照相机,用于可视地指示可插入到数字照相机中的多个相应的可拆卸存储卡中可用于存储的存储器空间量。 数字照相机包括用于捕获和数字化图像数据的装置,显示器和用于在显示器上构建存储卡充满度图标的处理器。 每个存储卡充满度图标包括内部部分,其可以被调整以图形地显示可用于存储在其相应的可移动存储卡中的存储器空间的相对量。 数字照相机还包括用于将数字化图像数据传送到所选择的可移动存储卡的电路。 处理器确定所选择的存储卡中的可用存储器空间的相对量,并且修改显示器上的存储卡充满度图标的可调节内部部分,以图形格式指示所选择的存储卡中的可用存储器空间的当前相对量。

    • A technique for automatically focusing the lens of an electronic still camera employs a full frame image sensor 20 and a mechanical shutter 24. The image sensor 20 itself is operated first in a "fast flush" mode to focus a lens 22, and then in a normal readout mode to obtain the final still image. To focus the lens 22, the shutter 24 is opened, and an image is integrated on the sensor 20. The average contrast of a central region 66 of the image is used to determine how well the image is focused. The portion of the image surrounding the central region 66 is rapidly read out and discarded, using "fast flush" clocking where the vertical and horizontal registers are continuously clocked. The process is repeated numerous times with the shutter remaining open as the lens focus is adjusted until the maximum average contrast is obtained. At this point, the shutter is closed, and the entire sensor is cleared using "fast flush" clocking. The shutter is again opened to capture the final image, and closed while the final image is read out.
    • 用于自动聚焦电子静物照相机的技术采用全帧图像传感器20和机械快门24.图像传感器20本身首先以“快速冲洗”模式操作以聚焦透镜22,然后在 正常读出模式获得最终静止图像。 为了聚焦透镜22,打开快门24,并且将图像集成在传感器20上。图像的中心区域66的平均对比度用于确定图像的聚焦程度。 使用垂直和水平寄存器连续计时的“快速刷新”时钟,快速地读出并丢弃围绕中心区域66的图像的部分。 当调整透镜焦点直到获得最大平均对比度时,该过程重复多次,快门保持打开。 此时,快门关闭,并且使用“快速冲洗”时钟清除整个传感器。 再次打开快门以捕获最终图像,并在读取最终图像时关闭。
