Image processing apparatus, image processing method, and image processing system

An image processing apparatus comprising:

• an encoding processing unit that generates a plurality of encoded streams of different display sizes with respect to each of a plurality of picture contents, encodes the picture contents in units of predetermined blocks using the encoded streams, and generates an encoded stream of a multi-picture reproduction image to display the plurality of picture contents at the same time,
• wherein, when parameters regarding encoding of an original block that is a block of the picture contents corresponding to the predetermined block, which are included in the encoded streams of the picture contents, are prohibition parameters prohibited in the encoded stream of the multi-picture reproduction image, the encoding processing unit decodes the encoded streams of the original block, reencodes the streams, and sets the obtained encoded streams as the encoded streams of the predetermined block, and when the parameters of the original block are not the prohibition parameters, the encoding processing unit sets the encoded streams of the original block as the encoded streams of the predetermined block,
• wherein when the parameters of the original block are not the prohibition parameters and include a motion vector corresponding to a reference pixel, the encoding processing unit updates the motion vector on the basis of a change of display positions of the picture contents forming the multi-picture reproduction image, and sets the encoded streams of the original block in which the motion vector is updated as the encoded streams of the predetermined block, and
• wherein, when there are the picture contents based on the updated motion vector in a screen of the multi-picture reproduction image, the encoding processing unit sets the encoded streams of the original block including the motion vector as the encoded streams of the predetermined block, and when the picture contents based on the updated motion vector are not in the screen of the multi-picture reproduction image, the encoding processing unit decodes the encoded streams of the original block corresponding to the motion vector, reencodes the streams, and sets the obtained encoded streams as the encoded streams of the predetermined block.

An image processing system comprising a server device and a client device,

• wherein the server device includes an encoding processing unit that generates a plurality of encoded streams of different display sizes with respect to each of a plurality of picture contents, encodes the picture contents in units of predetermined blocks using the encoded streams, and generates an encoded stream of a multi-picture reproduction image to display the plurality of picture contents at the same time, and a transmitting unit that transmits the encoded stream of the multi-picture reproduction image generated by the encoding processing unit to the client device,
• when parameters regarding encoding of an original block that is a block of the picture contents corresponding to the predetermined block, which are included in the encoded streams of the picture contents, are prohibition parameters prohibited in the encoded stream of the multi-picture reproduction image, the encoding processing unit decodes the encoded streams of the original block, reencodes the streams, and sets the obtained encoded streams as the encoded streams of the predetermined block, and when the parameters of the original block are not the prohibition parameters, the encoding processing unit sets the encoded streams of the original block as the encoded streams of the predetermined block, and
• the client device includes a receiving unit that receives the encoded stream of the multi-picture reproduction image transmitted by the transmitting unit, and a display control unit that displays the multi-picture reproduction image on a predetermined display unit on the basis of the received encoded stream of the multi-picture reproduction image.
