An image capturing apparatus includes: an encoding unit configured to perform encoding processing on an image output from an image capturing unit for obtaining an image; a communication unit configured to receive designation of a resolution of the encoding unit from an information processing apparatus; an obtaining unit configured to obtain a resolution which is associated with the resolution set for the image capturing unit, and is settable for the encoding unit; a determination unit configured to determine whether the designated resolution is the resolution obtained by the obtaining unit and settable for the encoding unit; and a transmission unit configured to transmit an error response to the information processing apparatus, if the determination unit determines that the designated resolution is not the resolution obtained by the obtaining unit and settable for the encoding unit.
