Abstract
A hardware implemented method for interpolating missing colors is provided. In this method, the missing colors of a raw image received from an image capture device are interpolated using a first interpolation algorithm if the raw image is to be displayed on a display panel. It should be appreciated that the raw image is obtained through a color filter array. However, if the raw image is destined for output to a host, the missing colors of the raw image are interpolated using a second interpolation algorithm. An apparatus and a display controller for interpolating missing colors are also described.
Claims21
A hardware implemented method for interpolating missing colors, comprising method operations of:
- interpolating the missing colors of a raw image received from an image capture device using a first interpolation algorithm if the raw image is to be displayed on a display panel, the raw image being obtained through a color filter array;
- and
- interpolating the missing colors of the raw image using a second interpolation algorithm if the raw image is destined for output to a host.
A display controller for interpolating missing colors, comprising:
- a first interpolation module configured to convert a raw image to a red, green, and blue (RGB) format using a first interpolation algorithm, the raw image being obtained through a color filter array;
- and
- selection circuitry in communication with the first interpolation module, a display buffer, and an image capture device interface, the selection circuitry being configured to output the raw image received from the image capture device interface to the display buffer or to output the converted image in RGB format received from the first interpolation module to the display buffer based upon a selection signal received by the selection circuitry.
An apparatus for interpolating missing colors, comprising:
- a display controller including,
- circuitry for converting a raw image to a red, green, and blue (RGB) format using a first interpolation algorithm if the raw image is to be displayed on a display panel, the raw image being obtained through a color filter array,
- circuitry for outputting the converted image in RGB format to a display buffer if the raw image is to be displayed on the display panel or outputting the raw image to the display buffer if the raw image is destined for output to a host, and
- circuitry for converting the raw image stored in the display buffer to the RGB format using a second interpolation algorithm;
- a central processing unit (CPU) in communication with the display controller;
- the display panel in communication with the display controller for displaying the converted image in RGB format using the first interpolation algorithm;
- and
- an image capture device in communication with the display controller.
