Information processing apparatus, computer-readable non transitory storage medium storing image transmission program, and computer-readable storage medium storing image display program

An information processing apparatus for generating a plurality of images to be displayed on a display of a terminal device connected to the information processing apparatus via a network and transmitting the plurality of images to the terminal device, the apparatus comprising:

• an image memory configured to store the plurality of images;
• and
• a processor configured to execute a plurality of instructions, the instructions comprising:
• a first transmission instruction configured to transmit the plurality of images to the terminal device;
• an area determination instruction configured to determine an area in which frequency of change between frames of the plurality of images exceeds a threshold value;
• a second transmission instruction configured to compress the determined area at a frame rate higher than that of the first transmission instruction and transmitting the area to the terminal device;
• and
• a management instruction configured to manage synchronization between an image transmitted by the first transmission instruction and an image transmitted by the second transmission instruction, generate a drawing time of each image according to detection of a move of the area determined by the area determination instruction, and add the drawing time to the image transmitted by the first transmission instructions and the image transmitted by the second transmission instruction,
• wherein the drawing time is a time point when the frequency of change between frames exceeds the threshold and the drawing time includes information of a move destination position or a size of the area determined by the area determination instruction.
