Abstract

The invention discloses a color interpolating system and method. A spatial convolution unit receives output of an image sensor and carries out spatial convolution operation to generate convolution output. The color interpolation operation is carried out on the convolution output through the color interpolating unit to generate color interpolation output. A spatial deconvolution unit carries out spatial deconvolution algorithm on the color interpolation output by using inverse operation of the spatial convolution operation so as to generate a pre-treatment image. Although the structure of the system and the color interpolation operation are simple, more image resolution can be reserved, the proportion of color interpolation errors is reduced and the image quality is improved, particularly, the invention has better effect on image edges.

Description

technical field [0001] The invention relates to a digital image processing, in particular to a color interpolation system and method for image pre-processing. Background technique [0002] An imaging device, such as a digital camera or a digital video camera, converts image light into electronic signals through an image sensor (eg, a charge-coupled device (CCD) or a complementary metal-oxide-semiconductor (CMOS) image sensor). However, each photosensor of the image sensor is usually only used to capture one color, so the signal sensed and output by the photosensor array is not a complete picture that can be viewed by human eyes. Therefore, it is generally necessary to convert it into an image signal through color interpolation technology, which is generally called image pre-processing. [0003] There are many color interpolation methods for image pre-processing. Some methods are simple but will sacrifice image resolution, reduce contrast, and even cause image noise. Althou...
