Embodiment Construction

[0014] Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0015] refer to figure 2 , the essence of the present invention is: for the image data of the odd field 10 and the even field 20 output by the imaging device of the Frame Readout CCD, make it every adjacent two fields, that is, the nth field and the n+1th field image data all form a The complete image of the frame is displayed, where n is any integer greater than or equal to 1, such as figure 2 The first and second fields shown in make up the first frame, the second and third fields make up the second frame, the third and fourth fields make up the third frame, and so on. Except for the image data of the first field and the last field, the image data of other fields are used twice, that is, they are all displayed twice. Counting from the start of image acquisition, except for the first and second field images, it needs to wait for two In addition to ou...

Abstract

The invention discloses a processing method for high-resolution pictures. By adopting the processing method of the invention, for the image data of the odd field and the even field output by the image pick-up device of the Frame Readout CCD, the image data of every two neighboring fields, namely the 'n' field and the 'n plus 1' field, form a frame of complete image to be displayed, wherein 'n' is an arbitrary integer which is bigger or equal to 1. During the dynamic image processing course, except the data of the first field and the last field, data of other fields are used for two times, that is, data of other fields are displayed for two times; calculating from the beginning of collecting images, the images of the first and the second field need to wait for a two-field period for outputting a frame of image, while the images of other fields only need to wait for a one-field period for outputting and displaying a frame of complete image, thus the longer the time for collecting images is, the more approaching to the field rate output by Frame Readout CCD the frame rate is, which is two times of the frame rate of the traditional processing method.

Description

technical field [0001] The invention relates to an image processing method, in particular to a high-resolution image processing method. Background technique [0002] Frame Readout CCD is a kind of interlaced scanning (interline transfer) CCD, and its complete image data of one frame is divided into odd field image data and even field image data for output. The data is synthesized into a complete frame of image data and then displayed. [0003] At present, most of the popular digital cameras on the market, especially the low-end digital cameras, use Frame Readout CCD. These products use a small resolution when recording dynamic images, but in some other applications, such as digital microscopes, they are not Larger or even full-resolution dynamic images are required, and some of the popular camera devices on the market use the more expensive Progressive Scan CCD, while the camera devices using the Frame Readout CCD use the first and second scenes One frame of image is forme...
