First Claim
1. An image processing apparatus comprising:
- obtaining means for obtaining 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;
combining means for combining the first still image and second still image obtained by the obtaining means at a combination ratio which is changed along a time axis to generate a moving image;
encoding means for performing an encoding operation to encode the moving image generated by the combining means;
moving-image difficulty-level calculating means for calculating a moving-image difficulty level indicating a complexity of the moving image according to the first difficulty level and second difficulty level obtained by the obtaining means and the combination ratio changed along the time axis; and
control means for controlling a characteristic including an allocated bit rate of the encoding operation performed by the encoding means according to the combination ratio changed along the time axis and the moving-image difficulty level calculated by the moving-image difficulty level calculating means,wherein the control means determines whether the moving image is an I type according to the combination ratio.

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.
