• creating, as learning data, from a broadcast program in which the sponsorship credit display has been detected, a still image with the sponsorship credit display and a still image without the sponsorship credit display;
• using the created learning data to learn a parameter to be applied to a detection model for detecting a sponsorship credit display in a broadcast program;
• and
• using the detection model to which the learned parameter has been applied to detect a sponsorship credit display in a recognition target broadcast program.

A computer program causing a computer to function as the sponsorship credit display detection device, the device comprising:

• a learning data creator configured to create, as learning data, from a broadcast program in which the sponsorship credit display has been detected, a still image, wherein the sponsorship credit display is displayed and a still image where the sponsorship credit display is not displayed;
• a learner configured to, using the learning data created by the learning data creator, learn a parameter to be applied to a detection model for detecting a sponsorship credit display in a broadcast program;
• and
• a sponsorship credit display detector configured to, using the detection model to which the parameter learned by the learner, detect a sponsorship credit display in a recognition target broadcast program.
