Embodiment Construction

[0016] Certain terms are used throughout the description and claims to refer to particular components. It should be understood by those skilled in the art that hardware manufacturers may refer to the same component by different terms. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. "Includes" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". In addition, the term "coupled" here includes any direct and indirect electrical connection means. Therefore, if it is described in the text that a first device is coupled to a second device, it means that the first device can be directly electrically connected to the second device. second device, or indirectly electrically connected to the second device through other devices or connection means.

Abstract

The invention provides a pixel processing method. The method comprises the following steps: determining a first dispersion according to the difference between a preset color component value of a target pixel and a preset color component value of a peripheral pixel on a first direction; determining a second dispersion according to the difference between the preset color component value of the target pixel and a preset color component value of a peripheral pixel on a second direction; generating a first judgment value according to the preset color component values of a plurality of pixels on the first direction and the first dispersion; generating a second judgment value according to the preset color component values of a plurality of pixels on the second direction and the second dispersion; and selecting a plurality of specific pixels according to the first judgment value and the second judgment value to calculate a target color component value.

Description

technical field [0001] The present invention relates to a pixel processing method, in particular to a pixel processing method for reconstructing a missing color component in a pixel. Background technique [0002] In a conventional image processing system, when an image sensor senses an external image, the image sensor will transmit the color component value of each pixel to a line buffer ( Line Buffer), and temporarily stored in the line buffer, where each pixel contains only one color component value of one color, such as figure 1 shown. figure 1 Shown is a color filter array 10 generated by the image sensor of the conventional image processing system sensing the external image. Each row of the color filter array 10 is composed of different color component values ​​of each pixel (pixel) arranged alternately. For example in figure 1 In the above, the first line of the color filter array 10 stores the color component value of each pixel in the form of red and green (ie RG...
