Abstract
To improve an image recognition rate by quickly changing a parameter in a proper manner without being affected by a transmission delay of an image encoding stream in an image receiving device that recognizes a decoded image obtained by decoding the received image encoding stream. The image receiving device includes a data receiving unit, a parameter changing unit, a decoding unit, and an image recognition unit. The data receiving unit receives an image encoding stream including image encoding data and the parameter. The parameter changing unit changes the parameter received by the data receiving unit, that is, the parameter specified for encoding performed by a sender, to a value suitable for image recognition performed in the subsequent stage. The decoding unit generates the image decoding data by decoding the received image encoding data according to the changed parameter. The image recognition unit performs image recognition on the image decoding data.
