    • An image processing apparatus processes image data stored in a memory to thereby display an image on a display screen of a display unit under a control of a central processing unit (CPU). In one aspect of the invention, source data read from a source area of the memory are subjected to a rotation process and a logical operation and then converted to transfer data which will be written in a destination area of the memory by every word. In addition, first and last words within one line on the display screen are masked in accordance with predetermined first and second mask data. In another aspect of the invention, one of a wait mode and a not-wait mode is selected by wait control data outputted from the CPU. In the wait mode, the CPU is subjected to a wait state even in a memory read cycle. In the not-wait mode, the CPU is not subjected to the wait state normally in the memory read cycle. However, the CPU is subjected to the wait state in the not-wait mode while a reading operation of the memory has not been completed.
    • 图像处理装置处理存储在存储器中的图像数据,从而在中央处理单元(CPU)的控制下在显示单元的显示屏上显示图像。 在本发明的一个方面,从存储器的源区域读取的源数据经受旋转处理和逻辑运算,然后被转换为传送将被写入每个字的存储器的目的地区域中的数据。 此外,根据预定的第一和第二掩模数据,屏蔽显示屏上的一行内的第一个和最后一个字。 在本发明的另一方面,通过从CPU输出的等待控制数据来选择等待模式和不等待模式之一。 在等待模式下,即使在存储器读周期中,CPU也受到等待状态。 在不等待模式下,CPU在存储器读取周期中不会正常等待状态。 然而,在存储器的读取操作尚未完成的情况下,CPU在不等待模式下受到等待状态。

    • An image processing apparatus sequentially reads image data corresponding to an area to be displayed from an image memory by use of an access address. This image memory stores the image data corresponding to the display area and other image data for other uses. The access address for the image memory is determined by the image processing apparatus such that the access address is increased from the predetermined start address in response to a scanning of a display screen. When the access address reaches at a predetermined boundary address representative of an address of the last image data corresponding to the display area of the image memory, the access address jumps to a predetermined jump destination address (such as the start address). Hence, the display will be started from the jump destination address, whereby the other image data can be prevented from being used for the display or from being destructed.
    • 图像处理装置通过使用访问地址从图像存储器顺序地读取与要显示的区域相对应的图像数据。 该图像存储器存储对应于显示区域的图像数据和用于其他用途的其他图像数据。 图像存储器的访问地址由图像处理装置确定,使得响应于显示屏幕的扫描,访问地址从预定起始地址增加。 当访问地址到达表示与图像存储器的显示区域对应的最后图像数据的地址的预定边界地址时,访问地址跳转到预定的跳转目的地地址(例如起始地址)。 因此,显示将从跳转目的地地址开始,从而可以防止其他图像数据被用于显示或被破坏。

    • An image processing apparatus designed to interface with different monitors which processes image data read from a video random access memory (VRAM) so as to display an image corresponding to the image data on a screen of a display unit under a control of a central processing unit (CPU). The image processing apparatus at least provides a plurality of registers and a memory for storing several kinds of reference data for several kinds of predetermined modes. When one mode is selected from the predetermined modes, one of a color display and a monochromatic display is selectively performed on a screen of one of a color monitor and a monochromatic monitor or a screen of one of moniters each having different standard. The reference data corresponding to the selected mode are read from the memory and stored in the registers. When the selected mode is changed, reference data stored in requisite registers selected by newly selected mode are automatically rewritten by the reference data selected by the newly selected mode without exchanging programs of the CPU.
    • 一种图像处理装置,被设计成与处理从视频随机存取存储器(VRAM)读取的图像数据的不同监视器接口,以便在中央处理单元的控制下在显示单元的屏幕上显示与图像数据相对应的图像 (中央处理器)。 图像处理装置至少提供多个寄存器和用于存储几种预定模式的几种参考数据的存储器。 当从预定模式中选择一个模式时,有选择地在彩色监视器和单色监视器之一的屏幕上显示彩色显示器和单色显示器之一,或者每个显示器具有不同标准的监视器之一。 对应于所选模式的参考数据从存储器读取并存储在寄存器中。 当所选择的模式被改变时,由新选择的模式选择的所需寄存器中存储的参考数据将被新选择的模式所选择的参考数据自动重写,而不用交换CPU的程序。

    • A detecting unit detects any image area corresponding to a subject from the first image which is reduced resolution of an image that captured by an image capturing unit. With no image area detected as corresponding to the subject, a first control unit deems that an image area corresponding to the subject is absent in the image that captured by the image capturing unit. On the other hand, when the detecting unit detects an image area corresponding to the subject, a first determining unit determines whether or not the image area that detected by the detecting unit is an image area corresponding to the subject. If the area is determined to correspond to the subject, a second control unit deems that an image area corresponding to the subject is present in the image that captured by the image capturing unit.
    • 检测单元从第一图像检测与被摄体相对应的任何图像区域,该图像区域由图像捕获单元捕获的图像的分辨率降低。 在没有检测到与对象对应的图像区域的情况下,第一控制单元认为在由图像捕获单元捕获的图像中不存在与被摄体对应的图像区域。 另一方面,当检测单元检测到与被摄体对应的图像区域时,第一确定单元确定由检测单元检测到的图像区域是否是与被摄体对应的图像区域。 如果确定该区域对应于被摄体,则第二控制单元认为与被摄体对应的图像区域存在于由图像拍摄单元拍摄的图像中。
