Abstract: An imaging apparatus includes an imaging element that outputs a video signal and to which a processor drive clock is input from an external image processor. The imaging apparatus father includes a clock generation circuit and a memory. The clock generation circuit generates a clock synchronized with the video signal output from the imaging element. The memory stores the video signal output from the imaging element in synchronization with the clock synchronized with the video signal and outputs the stored video signal in synchronization with the processor drive clock.

Abstract: In an image data transmission system, even when encoded serial digital data transmitted from an endoscope to a video processor cannot be decoded due to a shift in a delimiter position as a result of a lack of the serial digital data or the like, a communication transmission section transmits error announcement information to a communication reception section in the endoscope based on a decoding error signal from a decoding error detection section, and a control code insertion section that has received the information instructs an encoding section to insert a control code for synchronization at a timing of occurrence of an error.
