    • A timing generator includes a frame rate information receiver, a display control section, and a determination unit. The frame rate information acquisition section is configured to receive information indicating a frame rate of an image sensor. The display control section is configured to output dot clocks in a first cycle to a display which includes a counter being configured to count the number of the dot clocks for a synchronization period, where the dot clocks are a synchronization signal. The determination unit is configured to determine whether or not the number of the dot clocks in the synchronization period is expected to exceed a predetermined number, where length of the synchronization period is based on at least the frame rate of the image sensor. The display control section is configured to switch from the first cycle to a second cycle, if the number of dot clocks is expected to exceed the predetermined number.
    • 定时发生器包括帧速率信息接收器,显示控制部分和确定单元。 帧率信息获取部被配置为接收指示图像传感器的帧速率的信息。 显示控制部分被配置为将第一周期中的点时钟输出到显示器,该显示器包括被配置为对同步周期的点时钟数进行计数的计数器,其中点时钟是同步信号。 确定单元被配置为确定同步周期中的点时钟数是否期望超过预定数量,其中同步周期的长度至少基于图像传感器的帧速率。 如果点时钟的数量预计超过预定数量,则显示控制部分被配置为从第一周期切换到第二周期。

    • A memory controller including: a rectangular area designation register which is used for designating a rectangular area inside a display area; an address generation circuit which generates an address of the memory corresponding to a position of each pixel inside the rectangular area; a color designation register in which designated pixel data is designated; and a bit block transfer control register. When the bit block transfer is enabled, the memory controller writes the designated pixel data in the memory based on the address generated by the address generation circuit corresponding to a bit block transfer rectangular area. When the bit block transfer is disabled, the memory controller writes input pixel data in the memory based on the address generated by the address generation circuit corresponding to an input pixel data transfer rectangular area.
