1228915 V. Description of the invention (6) The daytime data of the image is displayed on the screen (step 402), and the pixel data corresponding to the image of the area is obtained from this daytime data (step 403), and the daytime data The elementary data is temporarily stored in the image temporary storage module (step 404), and then the obtained elementary data is displayed on the display screen (step 405) with a fixed display of the elementary daylighting. When the device of this digital zoom method is aimed at the scene to take a photo (not shown in the figure), the scope of the scene obtained by the lens can be converted into valid daylight data that can be processed by this device after processing by this device. It is temporarily stored and displayed through a fixed pixel display on the display. This device can be set to display all the valid pixel data or part of the valid day pixel data when the device is turned on. This valid day pixel data already includes the entire range of the scene that can be obtained by the lens. The number of CCD or CMOS sensors is related. For example, assuming that the effective pixels of this device are 3 5 2 * 2 8 8, the number of sensors will be slightly larger than 3 5 2 * 2 8 8. Therefore, in this case, the scene obtained by the lens will be temporarily stored in an image temporary module with the effective pixel data of 3 5 2 * 2 8 8 and fixed at the beginning according to the preset settings. The pixel display screen displays all the valid pixel 3 5 2 * 2 8 8 data or some valid day pixel data. In the above example, you can first assume that the fixed display of the display is 176 * 220, and assume that the built-in setting is to display all valid pixel data on the display when it is turned on. At this time 3 5 2 * 2 8 The diurnal data of 8 must be processed by the central processing module, so that the 3 5 2 * 2 8 8 diurnal data can be completely displayed on the display screen that can only display 1 7 6 * 2 2 0 diurnal data, of which The processing method may include a drop point and the like. In general, the display on a device may not be fully displayed

Page 10 1228915 V. Description of the invention (7) The scene data of size 3 5 2 * 2 8 8 may only show 1 7 6 * 2 2 0 due to the built-in camp screen display setting. So if you want to display 3 5 2 * 2 8 8 pixel data on this display screen, you can only display a part of the area of this pixel data, not the entire pixel data. Software-assisted methods must be used to enable the complete scene range to be displayed on the Xiaodisu display screen. The software-assisted method includes the aforementioned drop-point method. When the zoom image key is pressed (zoom i η), the central part of the previous image is displayed on the monitor screen, and the image range is smaller, but the relative scene becomes larger, so it has the effect of enlarging the image. The process is: when the zoom-in image key is pressed (ζ ο 〇mi η), the central processing module controls to obtain a pixel of a certain size from the center of the daytime data of 3 5 2 * 2 8 8; for example, 2 3 4 * 1 9 2 celestial element but the same appears on the display that can only display 176 * 2 2 0 celestial element, so there will be an effect of magnifying the foreground object when viewing. Similarly, if the enlarged image key is pressed again (ζ 〇om i η), the central processing module will obtain a smaller day element from the center of the day element data of 2 34 * 1 9 2, such as 187 * 1 5 The daylight element of 3 is displayed on the display screen, so that it has the effect of enlarging the image. On the other hand, when the image reduction button is pressed (ζ ο 〇m 〇ut), the display will show a larger image than the image displayed on the display, but the scene inside will become smaller. The pixel data needs to be obtained from the effective pixel data for processing. In this example, it is 3 5 2 * 2 88 daylight data, so the area of daylight pixels that can be obtained to reduce the image can only be less than 3 5 2 * 2 8 8 pixel area, so the range of objects that can be displayed by pressing the image reduction button cannot exceed the range of objects that can be obtained by the original lens, but it must be larger than the image pixels displayed on the monitor. As shown on the display
