Abstract
An image processing apparatus includes the following elements. An obtaining unit obtains a first still image, a first difficulty level indicating a complexity of the first still image, a second still image, and a second difficulty level indicating a complexity of the second still image. A combining unit combines the first and second still images at a combination ratio which is changed along a time axis to generate a moving image. An encoding unit encodes the moving image. A moving-image difficulty-level calculating unit calculates a moving-image difficulty level indicating a complexity of the moving image according to the first and second difficulty levels and the combination ratio changed along the time axis. A control unit controls a characteristic of a process of encoding the moving image according to the combination ratio changed along the time axis and the moving-image difficulty level.
