1. An image processing apparatus comprising:
a processor comprising hardware, wherein the processor is configured to:
continuously receive first image information signals, where each of the first image information signals corresponds to one of a plurality of input frames;
output a second image information signal, based on one of the first image information signals corresponding to a first input frame of the plurality of input frames, to at least a first route;
continuously output third image information signals, where each of the third image information signals is based on a corresponding one of the first image information signals, to a second route;
apply a predetermined analysis to the second image information signal and output a result of the predetermined analysis; and
generate and continuously output fourth image information signals, where each of the fourth image information signals corresponds to one of a plurality of output frames,
wherein each of the fourth image information signals is based on a corresponding one of the first image information signals,
wherein, where a period of each of the plurality of input frames is f, output of the each of the fourth image information signals is delayed relative to the receipt of the corresponding one of the first image information signals by xf, where x is less than 1,
wherein one of the fourth image information signals is based on one of the third image information signals based on the one of the first image information signals corresponding to the first input frame, and
wherein a subsequent one of the fourth image information signals outputted is based on a subsequent one of the third image information signals with information based on the result of the predetermined analysis superimposed thereon, with superimposition of the information based on the result of the predetermined analysis being started in the generation of the subsequent one of the fourth image information signals and the generation of the subsequent one of the fourth image information signals is delayed relative to the receipt of the one of the first image information signals by yf, where y is greater than 1.
