Abstract
There is provided an image processing apparatus including a model-based processing unit that executes model-based processing for converting resolution and converting an image on the basis of a camera model and a predetermined model having aligning, with respect to a high-resolution image output one frame before, and a prediction operation unit that performs a prediction operation on a pixel value of a high-resolution image to be output, on the basis of parameters stored in advance, an observed low-resolution image that is an input low-resolution image, and an image obtained by executing the model-based processing.
Claims9
An image processing apparatus comprising:
- a central processing unit operable to:
- generate an estimated low-resolution image from a first high-resolution image output one frame before, wherein the estimated low-resolution image is generated by performing motion compensation on the first high-resolution image;
- and
- predict a pixel value for a second high-resolution image to be output based on the estimated low-resolution image, an observed low-resolution image, first parameters stored in advance and second parameters stored in advance,
- wherein the pixel value for the second high-resolution image is predicted based on summation of products of the first parameters and corresponding pixel values of the observed low-resolution image, and products of the second parameters and corresponding pixel values of the motion compensated first high-resolution image.
An image processing method comprising:
- in a central processing unit:
- generating an estimated low-resolution image from a first high-resolution image output one frame before, wherein the estimated low-resolution image is generated by performing motion compensation on the first high-resolution image;
- and
- predicting a pixel value for a second high-resolution image to be output based on the estimated low-resolution image, an observed low-resolution image, first parameters stored in advance and second parameters stored in advance,
- wherein the pixel value for the second high-resolution image is predicted based on summation of products of the first parameters and corresponding pixel values of the observed low-resolution image, and products of the second parameters and corresponding pixel values of the motion compensated first high-resolution image.
A non-transitory computer-readable storage medium having stored thereon, a computer program having at least one code section for image processing, the at least one code section being executable by a computer for causing the computer to perform steps comprising:
- generating an estimated low-resolution image from a first high-resolution image output one frame before, wherein the estimated low-resolution image is generated by performing motion compensation on the first high-resolution image;
- and
- predicting a pixel value for a second high-resolution image to be output based on the estimated low-resolution image, an observed low-resolution image, first parameters stored in advance and second parameters stored in advance,
- wherein the pixel value for the second high-resolution image is predicted based on summation of products of the first parameters and corresponding pixel values of the observed low-resolution image, and products of the second parameters and corresponding pixel values of the motion compensated first high-resolution image.
