AI Technical Summary

Problems solved by technology

[0007] However, in this way, because the overall volume of the image processor 12 is limited to a certain extent, the storage buffer 13 must be built externally, and cannot be installed inside the image processor 12.
This result cannot effectively reduce the manufacturing cost of the system manufacturer

Embodiment Construction

[0033]The inventive spirit of the present invention is further illustrated by taking the structure shown in FIG. 1 as an example. If the image sensor 11 is a CMOS image sensor that can originally belong to the image frame of the RGB image signal format, output the image frame of the YCbCr image signal format through hue conversion processing, and the image processor 12 with DSP function is designed as The image frame needs to be compressed into image compression data in the form of JPEG. When performing the JPEG compression algorithm, the image block with the size of 16×16 or 8×8 is usually used as the operation object for the subsequent execution of the sub-sampling algorithm (sub-sampling) rule, which means that the image processor 12 at least It is necessary to read 16 columns or 8 columns of image signals from the memory buffer 13 to complete the sub-sampling calculation rule. Based on this concept, if the storage capacity of the storage buffer register 13 can be reduced ...

Abstract

The method includes following steps: a) provides image signal temporary storage area containing at least two memories; each capacity of memory is less than 1 / 2 total pixels of image frame, and more than or equal to the total pixels of a group of image signals; b) the multi groups of image signal are inputted in turn to the two memories and are made image processing; when one of two memories only stores one group of image signals, the other groups of image signals in the image frame, which are not inputted into the temporary storage area, are inputted by turns, and covers the image signals in the temporary storage area, which has completed image process.

Description

technical field [0001] The invention relates to a method for processing an image frame, in particular to a method for processing an image frame which reduces the storage capacity of a memory buffer (memory buffer) used for processing the image frame. Background technique [0002] As the current digital image processing technology is becoming more and more advanced and developed, the related applications are becoming more and more popular, for example, discussing web cameras, network digital cameras, cellular and picture phones, personal digital assistants (PDA) ), multimedia computers and other technologies related to digital image processing are in the ascendant. The present invention is an invention related to the digital image processing technology. [0003] The digital image processing technology used in the above-mentioned related products usually uses at least an image sensor 11, an image processor 12 with a digital signal processing (DSP) function, and a storage buff...
