Abstract
Reduction in power consumption is not considered in the prior art documents. Provided is an encoding method for encoding image information and having: a step in which image information is input; an analysis step in which the characteristics of the input image information are analyzed; a bit depth output step in which the bit depth for video encoding is determined and output; and an encoding step in which the bit depth output in the bit depth output step is used and the input image information is encoded. The encoding method is characterized by the output bit depth being switched in the bit depth output step, on the basis of the analysis results from the analysis step.
Claims14
An encoding method comprising:
- a step in which an image information is inputted;
- an analysis step of analyzing a feature of the inputted image information;
- a bit-depth output step of determining and outputting a bit-depth with respect to video encoding;
- and
- an encoding step of performing an encoding process on the inputted image information using the bit-depth output in the bit-depth output step,
- wherein, in the bit-depth output step, a bit-depth to be output is switched based on an analysis result in the analysis step.
An encoding device comprising:
- an input unit to which image information is inputted;
- an analysis unit that analyzes a feature of the image information inputted to the input unit;
- a bit-depth output unit that determines and outputs a bit-depth with respect to video encoding;
- and
- an encoding unit that performs an encoding process on the image information inputted to the input unit using the bit-depth output from the bit-depth output unit,
- wherein the bit-depth output unit switches a bit-depth to be output based on an analysis result of the analysis unit.
An encoding device comprising:
- an input unit to which image information is inputted;
- and
- an encoding unit that performs an encoding process on the image information inputted to the input unit,
- wherein the encoding unit performs the encoding process with a first bit-depth B when image information having a first feature amount is inputted to the input unit, and
- the encoding unit performs the encoding process with a second bit-depth A, different from the first bit-depth B, when image information having a second feature amount, different from the first feature amount, is inputted to the input unit.
