IX. INSTRUCTIONS: [Technical Field] The present invention relates to a camera mobile communication terminal, and more particularly to a mobile communication terminal capable of eliminating image blur caused by jitter when photographing. [Prior Art] With the development of telecommunications technology, mobile communication terminals such as mobile phones have been rapidly popularized. Most of the current mobile communication terminals are equipped with a lens module to provide a camera function on the mobile communication terminal. Due to the convenience of the mobile communication terminal, the mobile communication terminal is more convenient than taking a photo with a special digital camera. Therefore, it is also deeply loved by people. In addition, with the development of telecommunications technology, video telephony has gradually entered the lives of people. Therefore, it is required to install a lens module for collecting video on a mobile communication terminal. However, when the mobile communication terminal is held, the hand shake may cause blurring of the photograph or the video surface. This phenomenon is caused by the fact that the lens module is constantly changing compared to the orientation of the object being photographed during the exposure, and the image of the object of the image sensor is constantly changing, and occurs when all the image data in the exposure time are superimposed. The phenomenon of blurring. Since the user generally aligns the lens module with the object to be photographed when photographing, even if the optical axis is aimed at the object being photographed, in general, when photographing with a camera mobile communication terminal, the main factor causing image blurring is perpendicular to The translation of the lens module in the direction of the optical axis. This translation causes the image of the same point on the object being photographed to be sensed by different pixel points on the image sensor at different times during the exposure time. In general, when photographing, only the image data 200828955* sensed from the same pixel point on the image sensor is superimposed at different times during the exposure time, so that the same point on the object has a complex image, and these The image overlaps with the image of other points, resulting in blurred images. In view of the above, it is necessary to provide a camera mobile communication terminal that can eliminate image blur due to jitter. SUMMARY OF THE INVENTION A photographable mobile communication terminal capable of eliminating image blur due to jitter will be described below by way of example. A mobile communication terminal includes a main body, a lens module, two acceleration sensors, a processor and a distance measuring module, and the lens module, two acceleration sensors, a processor and a distance measuring module are installed in the Inside the subject. The lens module includes an image sensor. The two acceleration sensors are respectively configured to sense accelerations in two directions perpendicular to the optical axis of the lens module, the two directions being perpendicular to each other. The ranging module is configured to sense a distance between the object to be photographed and the lens module. The processor is configured to process the image data sensed by the image sensor according to the distance and the acceleration signal sensed by the acceleration sensor to eliminate image blur caused by the jitter. A mobile communication terminal comprises a main body, a lens module, two acceleration sensors, a processor and a distance measuring module, wherein the lens module, two acceleration sensing, a processor and a distance measuring module are installed in the office Inside the subject. The lens stack includes an image sensor. The two acceleration sensors are respectively used to sense the acceleration of the lens module in two directions. The ranging module is used to measure the object distance. The processor is configured to process the image sensor according to the object distance and the acceleration signal sensed by the acceleration sensor. The image is processed to eliminate image blur caused by the jitter. Compared with the prior art, the mobile communication terminal uses the acceleration sensor to sense the vibration in two directions perpendicular to the optical axis of the lens module, and senses the signal to the image sensor according to the vibration. The compensation operation is performed, thereby eliminating image blur caused by lens module shake. [Embodiment] Referring to FIG. 1, the mobile communication terminal of the first embodiment includes a main body 10, a lens module 12, acceleration sensors 141 and 142, a processor 16, and a distance measuring module 18.

The processor 16 is respectively connected to the ranging module is, the acceleration sensor 141, the acceleration sensor 142 and the button 1〇2, and the button 102 is used to control whether the processor 16 turns on the anti-shake function. Of course, the button 1〇2 can be omitted, and the processor 16 can be simply turned off. The acceleration sensors 141, 142 can be compressed and accelerometer sensors, capacitive acceleration sensors, torsional pendulum acceleration sensors or tunneled acceleration sensors. The sensing sensor of the acceleration sensor and the acceleration sensor 142 200828955 * is perpendicular to each other, and the sensing direction is perpendicular to the optical axis of the lens module 12, thereby achieving vibration in two directions perpendicular to the optical axis Sensing. It is noted that the direction sensed by the acceleration sensor 141 is the X direction, and the direction sensed by the acceleration sensor 142 is the Y direction. The optical axis of the lens module 12 is located in the z direction. 3 is a schematic view of a piezoresistive acceleration sensor used in the present embodiment, which includes a base body 140, elastic arms 142a, 142b, masses 144a, 144b, and piezoresistive sheets 146a, 146b. The ends of the elastic arms 142a, 142b are respectively connected to opposite sides of the base body 140, and the other ends are respectively connected to the mass blocks 144a, 144b 10, and the piezoresistive pieces 146a, 146b are respectively attached to the elastic arms 142a, 142b. Referring to Figure 4, the piezoresistive plates 146a, 146b are connected to the same Wheatstone bridge circuit as the two arms adjacent to the Wheatstone bridge. When there is an acceleration input, the elastic arms 142a, 142b are deformed under the inertial force of the mass 144&, 1441) respectively, causing the piezoresistive sheets 146a, 146b to be deformed accordingly, and the resistance value is due to the pressure. The resistance changes and changes. The initial resistance values of the piezoresistive sheets 146a and 146b are R1 and R2, respectively, and the deformation causes the resistance value of the sensation to change to ΔΙΙ. Assuming that the resistance of the piezoresistive sheet 146a is increased, the resistance of the piezoresistive sheet 146b is lowered. The resistance of the resistor 146c is R3. The resistance change of the piezoresistive sheets 146a, 146b causes the bridge to lose balance. At this time, the variable resistor 146d is adjusted to rebalance the bridge, and the resistance of the variable resistor 146d is R4. At this time, there is a relationship (R1 + Δ R) / (R2 - ΔR) = R3 / R4. The Δ R can be calculated from the formula (R2xR3-RlxR4)/(R3+R4). Since there is a one-to-one correspondence between Δ R and the deformation of the piezoresistive sheets 146a, 146b, and the deformation is related to the magnitude of the inertial force, the acceleration is proportional to the inertial force, so the magnitude of the input acceleration can be calculated. The advantage of this kind of accelerometer is that the resistance of the two piezoresistive layers of 200828955 is just opposite, and the change is relatively large. Whistler has two ancient films, “146” and the value is relatively sensitive. There is a ^degree of breakage, which means that the acceleration is used in the anti-shake mode. The specific process of the mobile communication terminal is as follows: Assume that the exposure time of the lens module 12 is τ when photographing, In the τ time, the mirror track group 12 has an acceleration due to the application of an external force, and the acceleration thereof constantly changes as the external force changes continuously, and the speed of the lens module 12 in the direction of the αχ is as an example. %, the acceleration in the X direction is at, taking a time interval ^ 〖, as long as it is small enough, its acceleration can be regarded as not changing within Δί, then the speed of the rear lens module 12 is Vt+atxM, At The displacement as occurred in time is (2Vt+atxM)xM/2. Since the initial displacement of the lens module 12 is zero, and the initial acceleration is regarded as zero, the velocity Vt at any time t can be calculated. That is, the displacement Δ$ of the lens module 12 in any Δt can be calculated as φ to, and the total displacement & of the lens module 12 compared to the initial position at time t can also be calculated. The above calculation process is performed by the processor 16. Therefore, the displacement of the lens module 12 jitter during the photographing process can be measured by the processor 16 in real time. Referring to FIG. 5 , it is a schematic diagram of the imaging optical path of the lens module 12 . The image 124 is the image of the object 122 at the start of exposure, and the image 126 is the image of the object 122 at time t, and the displacement of the image 126 compared to the image 124 is (L + image distance) xSt/L. Where l is the object distance and is measured by the ranging module 18. For a designed lens module, the initial image distance is a fixed preset value. After autofocusing, since the mirror 200828955 • the image moves before and after, the image distance will change, so the image distance is the initial value plus/minus - The distance to move when autofocusing. The focus distance is generally calculated by the processor based on the object distance L. Through the above process, the displacement change of the image formed by the lens module 12 during the photographing process can be instantaneously measured. Referring to FIG. 6', when the lens module 12 is displaced in the X direction, the displacement of the image sensor 120 in the X direction is also St, and the displacement of the image of the object ι22 in the X direction is (L+image distance) xSt. /L, that is, taking the pixel point 12〇1 as an example. The image formed at time t should be imaged at the pixel point 1202 when the exposure is started. The pixel point 1202 is shifted to (L + image distance) xSt / L - St compared to the pixel point 12 〇 1 in the χ direction. At time t, the processor superimposes the signal sensed by the pixel point 1202 with the signal sensed by the primitive point 1201 at the beginning of the exposure, and of course, similar operations are performed for all other primitive points. This is only one of the moments of t·························································································· Exposure _ light into the translation of the in, and then perform compensation operations. This process continues until the end of the photo. Δί can be equal to the data reading of the image sensor 12G. The above is only explained by taking the x direction as an example, and of course, a similar process is performed simultaneously in the Y direction. The above description is made by taking the χ and γ directions perpendicular to the optical axis as an example, but X and γ may not be perpendicular to the wire. The process of eliminating image blur is similar. In the mobile communication terminal of the present example, the same point on the object to be photographed: the image at different times is still sensed by different points on the image sensor, but the acceleration sensor can sense the lens module. In the two verticals of the 200828955 .=Up ί vibration, the processing 11 16 calculates the phase of each moment according to the county material:: the material is set to 'the offset of the image' and the image of the same point is shaken, Plus, and the image data of the same----------------------------------------- Referring to FIG. 7, the mobile communication terminal of the second embodiment is the same as the step-in-step including the infrared lens module 22: the lens module 22 is photographed. The user takes photos alone or assists in taking pictures. The user can select (4) what kind of mode can be selected in the auxiliary camera mode. The processor 26 senses the lens module 22, and the image data and the infrared money source group are used for image acquisition. In the mobile communication terminal of the embodiment, the infrared lens template is used to take pictures or assist in taking pictures in a dark environment, thereby improving the compatibility.衣兄·^周... The advantage of the mobile communication terminal of the present embodiment is that the acceleration sense is used to sense the two directions perpendicular to the optical axis of the lens module, and the image is sensed according to the vibration. The sensed signal is compensated, thereby eliminating image blur caused by lens module shake. In summary, the present invention has indeed met the requirements of the invention patent, and has proposed a special shot in accordance with the law. However, the above description is only a preferred embodiment of the present invention, and it is not possible to limit the scope of the patent application of the present invention.
