Embodiment Construction

[0023] Described here is a computer device that processes data automatically. The device is realized by software or hardware or a combination of software and hardware, and components of the device can be located in and / or realized by a computer system. These computer systems can be networked and may employ different networking technologies, including wire, optical cross-sight, and radio frequency networks. Established network connections may be permanent, session based, or intermittent, eg, packet based. Raw image data, intermediate data resulting from processing the raw data, and final processed image data may similarly reside on these computer systems. Those skilled in the art can understand that the above-mentioned devices can also be applied in other wider environments.

[0024] In some embodiments, the above-mentioned equipment may be an image acquisition system, such as a video camera, a monitor, a digital camera (digital still camera), a digital camcorder, or a PC cam...

Abstract

Image data in a first color space is converted to image data corresponding to a second color space. Image processing of the image data occurs in the second color space. After image processing is complete, the image data is then converted to image data in any one of the following color spaces: the first color space, a third color space, or the second color space but using a conversion method that is different than the conversion method used to convert the image data from the first color space to the second color space.

Description

technical field [0001] The present invention relates to image processing, and more particularly, the present invention relates to image processing in color spaces. Background technique [0002] Current image data processing methods for high-quality images are very expensive. For example, when all image processing occurs in YUV color space, the processing cost and data storage cost are quite high. at YC b C r Image processing in color space also has a higher cost. On the other hand, if all image processing is performed in the RGB raw color space, the storage and processing costs are relatively small. But the quality of the image produced in the RGB primary color space is poor. [0003] To sum up, an efficient method is needed to generate high-quality images. Contents of the invention [0004] One of purpose of the present invention is to provide a kind of processing method of image data, and this processing method comprises: [0005] Process A: converting image data ...
