Abstract: An information processing apparatus is configured to acquire detection target sizes at individual positions in an image, set a plurality of detection regions for the image, and detect a detection target in each detection region from the image acquired. At the time of setting the detection regions, based on the detection target sizes at the individual positions, sizes of the detection regions at the individual positions in the image and overlapping ranges between adjacent detection regions are set.

Abstract: An accessory apparatus switches between a first communication mode where a signal for performing flow control is transmitted via a signal line CS each time a frame of data is transmitted via a signal line DATA and a second communication mode where the signal for performing the flow control is received via the signal line CS each time a predetermined number of blocks of data is transmitted via the signal line DATA.

Abstract: An imaging apparatus to which an accessory apparatus is attachable includes a camera controller configured to communicate with the accessory apparatus. The camera controller receives first information on a data size receivable by the accessory apparatus, performs a setting for a data size to be transmitted to the accessory apparatus based on the first information, and communicate with the accessory apparatus based on the setting.

Abstract: An imaging apparatus to which a plurality of accessory apparatuses are attachable includes a camera communicator configured to provide a communication path with each of the plurality of accessory apparatuses, and a camera controller configured to communicate with the plurality of accessory apparatuses via the camera communicator. The camera controller transmits a first request to the plurality of accessory apparatuses, receives first information corresponding to whether or not to stop a communication with the imaging apparatus from each of the plurality of accessory apparatuses that have received the first request, and controls a communication with each of the plurality of accessory apparatuses according to the first information.
