Abstract: Where a highly accurate image analysis is required, for example, only RAW images selected according to specified conditions are selected and transmitted to a server. There are provided an imaging unit that is mounted on a movable device, an image signal processor that generates a color image by signal processing of the RAW image which is an output of an imaging element of the imaging unit, an image analysis unit that executes analysis processing of the color image, a transmission necessity determination unit that determines transmission necessity of the RAW image to the server, and a transmission unit that transmits the RAW image to the external server according to a determination result. The transmission necessity determination unit decides the transmission necessity of the RAW image on the basis of a transmission timing control at constant intervals, imaging and signal processing parameters, an image analysis result, device information, or the like.
