    • High-order bits to be utilized for current-frame display data and previous-frame display data, and low-order bits to be utilized for the current-frame display data alone are stored in independently controllable memory areas. For reading the current-frame display data from a frame memory, data of the high-order bits and data of the low-order bits are read. For reading the previous-frame data, the high-order bits alone are read. Thus, since a period during which the data of the low-order bits that is not utilized for the previous-frame display data is stored in the memory is shortened, a required memory capacity can be reduced. The data transfer time can be reduced by the time required for memory read for the data of the low-order bits that is not utilized for the previous-frame display data.
    • 用于当前帧显示数据和前一帧显示数据的高位数,以及仅用于当前帧显示数据的低位比特存储在独立可控存储区域中。 为了从帧存储器读取当前帧显示数据,读取高位数据和低位数据的数据。 为了读取前一帧数据,只读取高位。 因此,由于缩短了对前一帧显示数据未被利用的低位数据的数据存储在存储器中的时段,所以可以减少所需的存储器容量。 数据传输时间可以减少对于未用于前一帧显示数据的低位的数据的存储器读取所需的时间。

    • A radiation-image photographing apparatus is provided with a voltage controlling switch 52 for switching voltage which is applied from a power source 53 to a detector 10, a high-voltage generator 62 for supplying high voltage HV to a radiation source 61, and a control section 70 for controlling a light-source control section 40. When a generator switch 63a is on, the high-voltage generator 62 generates high voltage HV. The control section 70 senses that a signal S1 has gone low and makes a signal C2 high, whereby dc voltage is applied to the detector 10. After tp1 has elapsed since the signal C2 was made high, the control section 70 makes a signal C1 low, thereby causing the light-source control section 40 to be in a preexposure mode. After tp3 has elapsed since the emission of preexposure light P was started, the control section 70 makes a signal C3 high, thereby causing the radiation source 61 to emit radiation R. After te3 has elapsed since the emission of radiation R was started, the control section 70 causes the signal C2 to be in a high impedance state, thereby stopping the application of voltage to the detector 10.
