Sony patents video coding that adjusts resolution in steps
Sony describes a method for processing moving images by changing the resolution of frames in multiple steps rather than all at once. The system shrinks the image to a smaller size, places it within a standard frame, and encodes the result into a single data stream.
In the filing’s own words
The present disclosure relates to image processing apparatus and method that enable a reduction in subjective image quality to be suppressed. A moving image of a predetermined frame size is controlled so that a resolution of a frame image is changed in multiple steps, a reduced image is generated by reducing a size of the frame image of the moving image in accordance with the control, a position of the reduced image to be arranged in a frame of the frame size is set, and the moving image of the frame size including the frame in which the reduced image is arranged at the set position is coded as a single sequence to generate a bitstream. The present disclosure can be applied to, for example, an image processing apparatus or an image processing method.
What exactly they claim (claim 1)
1. An image processing apparatus, comprising: a resolution change control unit that performs control on a moving image of a predetermined frame size so that a resolution of a frame image is changed in multiple steps; an image reduction unit that generates a reduced image by reducing a size of the frame image of the moving image in accordance with the control of the resolution change control unit; a position setting unit that sets a position of the reduced image to be arranged in a frame of the frame size; and a coding unit that codes the moving image of the frame size including the frame in which the reduced image is arranged at the set position as a single sequence to generate a bitstream.
