General traditional scanning The lamp sources used in the device are mainly cold cathode tubes (c〇h Cathode FU〇rescent Lamp; CCFL). 'Although the cold cathode tube has the advantages of high degree of shell, low power consumption, long service life ... The main disadvantage is that every time the user restarts the scanner, it takes 1 warm-up time to allow the brightness of the lamp to slowly increase to a stable level. ^ Sadness, then start the picture. The work of tracing 'therefore needs to take some time to wait for the light source to warm up at (step 1 1). Under the condition of normal temperature, this warm-up time is about 1-3 minutes, however, for some cold zones For countries, users need to wait for a longer period of time. The scanner can only be used after time, causing considerable inconvenience to the user, and some users even mistakenly believe that the long waiting time is the reason of the system crash and request the return processing. Therefore, in the increasingly competitive environment of this product, How to reduce the waiting time of the traditional scanner before the cold scan is an important issue.

Description of the invention (5) Scanning this second reference whiteboard 40 with the redundant pixel reduction units (Dummy Pixel s) on both sides of the image sensing element of the optical-mechanical module 20 to measure the γ direction The brightness of each position, when the brightness detection of the entire Y direction is completed, the change of the brightness of the entire Y direction can be obtained. In this way, the image sensing element can be used to scan the AFE data obtained from the whiteboard 30 and the second reference whiteboard 40, respectively, and the γ-direction luminance change 'can be corrected by software to obtain normal digital image data. Therefore, after the optical-machine module 20 scans in the Y direction for the first time, the AFE data and the change in the Y-direction luminance can be used to simulate the state of the lamp source after warming up (that is, when the lamp source brightness is stable). Perform an immediate preview or scan. You don't need to wait for the brightness of the entire light source to stabilize before you can start the preview or scan to greatly reduce the waiting time before the cold scan. In addition to scanning the second reference whiteboard 40 with the redundant sensing units on both sides of the image sensing element to obtain the Y-direction luminance change, an additional photodiode can be set on one side of the optical machine module 20 The second reference white board 40 is scanned by the photodiode to measure the luminance at each position in the Y direction, and the luminance change in the entire Y direction can also be obtained. Then, the normal digital image data can also be obtained by using the obtained AFE data and the change in luminance in the Y direction through software compensation and correction.
