Image processing apparatus and method
An image processing apparatus receives a plurality of consecutive images, and regards pixels having the same coordinates in each of the consecutive images as a pixel match. The apparatus determines a range for red values, a range for green values, and a range for blue values in each pixel match, and filters out R, G, and B values which fall outside a corresponding range for the pixel match. In addition, the apparatus calculates an average R value, an average G value, and an average B value for each pixel match according to remaining R values, remaining G values, and remaining B values of the pixel match, and creates a new image by taking the average R value, the average G value, and the average B value of each pixel match as color values of a corresponding pixel in the new image.
1. An image processing method being performed by execution of instructions by a processor of an image processing apparatus, the method comprising:
receiving a plurality of consecutive images of an object captured by an image capturing unit of the image processing apparatus, wherein pixels having the same coordinates in each of the consecutive images represent the same part of the object and are regarded as a pixel match;
reading all red (R), green (G), and blue (B) values of each pixel match from the consecutive images;
analyzing all R, G, and B values of each pixel match to determine a common R value range, a common G value range, and a common B value range of the pixel match, and filtering R values, G values, and B values of the pixel match that respectively fall outside the common R value range, the common G value range, and the common B value range of the pixel match;
calculating an average R value, an average G value, and an average B value for each pixel match according to remaining R values, remaining G values, and remaining B values of the pixel match; and
creating a new image by taking the average R value, the average G value, and the average B value of each pixel match as color values of a corresponding pixel in the new image.
2. The method of claim 1 , further comprising: displaying the new image on a display device of the image processing apparatus.
3. The method of claim 1 , wherein the consecutive images and the new image are stored in a storage device of the image processing apparatus.
4. The method of claim 1 , wherein the image processing apparatus is a digital camera, a digital video, a computer or a mobile phone having image capturing function.
5. A non-transitory medium storing a set of instructions, the set of instructions capable of being executed by a processor of an image processing apparatus to perform an image processing method, the method comprising:
receiving a plurality of consecutive images of an object captured by an image capturing unit of the image processing apparatus, wherein pixels having the same coordinates in each of the consecutive images represent the same part of the object and are regarded as a pixel match;
reading all red (R), green (G), and blue (B) values of each pixel match from the consecutive images;
analyzing all R, G, and B values of each pixel match to determine a common R value range, a common G value range, and a common B value range of the pixel match, and filtering R values, G values, and B values of the pixel match that respectively fall outside the common R value range, the common G value range, and the common B value range of the pixel match;
calculating an average R value, an average G value, and an average B value for each pixel match according to remaining R values, remaining G values, and remaining B values of the pixel match; and
creating a new image by taking the average R value, the average G value, and the average B value of each pixel match as color values of a corresponding pixel in the new image.
6. The medium of claim 5 , wherein the method further comprises: displaying the new image on a display device of the image processing apparatus.
7. The medium of claim 5 , wherein the consecutive images and the new image are stored in a storage device of the image processing apparatus.
8. The medium of claim 5 , wherein the image processing apparatus is a digital camera, a digital video, a computer or a mobile phone having image capturing function.
9. An image processing apparatus, comprising:
a storage device;
