Abstract: The present invention relates to an image processing apparatus, an image processing method and a program, and a recording medium that allow for setting information allowing for easily controlling the granularity in trick play.A setting unit sets Supplemental Enhancement Information (SEI) about the encoded data of pictures. The SEI includes the reference layer information indicating layers of the reference relationship among the pictures. The present invention can be used, for example, for a recording device that encodes the video data in a High Efficiency Video Coding (HEVC) scheme in the Blu-ray (registered trademark) Disc (BD) standard.

Abstract: An optical axis or a diameter of light of even a light beam having a non-uniform intensity distribution is stably obtained. An outer shape of a range of a light intensity having a specified ratio with respect to a total light intensity on a cross-section of a light beam is obtained. An approximate circle is obtained from this outer shape. For example, the approximate circle is calculated by using the least-squares method. An optical axis and/or a diameter of light of the light beam is obtained on the basis of this approximate circle.
