    • A method of transferring encoded data and an imaging device executing the method thereof are disclosed. The image signal processor according to an embodiment of the present invention has an encoding unit, which generates encoded image data by encoding, in accordance with a predetermined encoding method, image data corresponding to an electrical signal inputted from an image sensor, and a data output unit, which temporarily stores the image data encoded by the encoding unit and transfers the stored encoded image data to a receiving part. The data output unit can input a skip command, which makes the process of a following frame skip, to the image sensor or the encoding unit in case input start information of the following frame is inputted from the image sensor or the encoding unit while a preceding frame is processed by the encoding unit, the skip command. Therefore, it becomes possible to increase the process efficiency of the back-end chip and to reduce the power consumption.
    • 公开了传送编码数据的方法和执行其方法的成像装置。 根据本发明的实施例的图像信号处理器具有编码单元,其通过根据预定编码方法通过编码来生成与图像传感器输入的电信号相对应的图像数据和数据输出的编码图像数据 单元,其临时存储由编码单元编码的图像数据,并将存储的编码图像数据传送到接收部分。 在从图像传感器或编码单元输入下一帧的输入开始信息的情况下,数据输出单元可以向图像传感器或编码单元输入跳过命令,跳过命令使后续帧跳过, 帧由编码单元处理,跳过命令。 因此,可以提高后端芯片的处理效率并降低功耗。
