Claim of US Patent No. 9,288,451

1. An image processing apparatus for transmitting image data of a plurality of frames to a client, comprising:
a memory;
a processor coupled to the memory which executes the following:
detecting an object in a frame;
determining that a first object detected in a first frame should be unidentifiable at the client if the first object satisfies
a predetermined condition;

determining whether second and third objects detected in a second frame after the first frame are divided from the first object
detected in the first frame;

determining whether the second object detected in the second frame is an abandoned object in accordance with whether the second
object stays in a predetermined range for a predetermined period of time;

determining that the second object detected in the second frame should be identifiable at the client if the second object
is not determined to satisfy the predetermined condition and that the third object detected in the second frame should be
unidentifiable at the client if the third object is determined to satisfy the predetermined condition and the second object
does not satisfy a condition to determine the second object as an abandoned object;

determining whether the second and third objects are detected in a third frame after the second frame;
determining whether the second object detected in the third frame is an abandoned object in accordance with whether the second
object stays in the predetermined range for the predetermined period of time; and

determining that the second object detected in the third frame should be identifiable at the client if the second object is
not determined to satisfy the predetermined condition and that the third object detected in the third frame should be identifiable
at the client if the second and the third objects are divided from the first object and the second object stays in the predetermined
range for the predetermined period of time.
