Abstract: An information processing apparatus is disclosed, including a detection part, a change part, and a determination part. The detection part detects a change of a first color temperature of an external environment. The change part changes a second color temperature of a display part at a predetermined speed to a targeted value corresponding to the first color temperature after the change in response to a detected change of the first color temperature. The determination part determines whether brightness of an image is changed, in response to a switch of the image on the display part. When it is determined that the brightness of the image on the display part is changed during the change of the second color temperature of the display part, the change part changes the second color temperature of the display part at a different speed from the predetermined speed.

Abstract: The invention provides encoded moving image data having good image quality even in a scene having a high difficulty level. A unit counts a number of pictures to determine a break between scenes. A unit encodes block by block in an inputted picture. A unit calculates a block distortion between a decoded picture and a picture before being encoded. A unit calculates a surplus encoded data amount with respect to an encoded data amount equally allocated to each scene from the encoded data amount of each picture and a preset sequence target bit rate. A target encoded data amount is calculated based on an average block distortion of a scene and the surplus encoded data amount. The encoded data amount of the first picture of a scene is compared with a threshold, and the initial parameter is corrected to determine the parameter for encoding the second and subsequent pictures.

Abstract: The invention generates encoded data that properly conforms to pre-specified image quality and suppresses a large change in image quality. An encoding unit encodes pictures block by block according to a parameter. A distortion amount calculation unit calculates a picture distortion amount between a decoded picture and a picture before being encoded. A scene distortion amount calculation unit calculates a scene encoding distortion amount from the picture distortion amounts of a plurality of pictures having been encoded. A distortion bit rate conversion unit calculates a corrected bit rate by calculating a difference between a target distortion amount and the calculated scene encoding distortion amount, and multiplying the calculated difference by a coefficient. A target bit rate calculation unit calculates a bit rate for a picture subsequent to a picture of interest by adding a current target bit rate to the corrected bit rate, and sets it as the parameter.
