Digital camera work basic principles: light - electricity - digital signal transfer and change. Through the light sensor signal into a current signal into analog and then digital signal processing by a dedicated chip, and filtering the information obtained to restore it is what we see a dynamic picture
Some Affect the Image Quality Reasons:
Camera Image is Not Good. This failure generally can be divided into three cases, one is shown in the viewfinder image and the TV is not ideal, leading to the reasons for this failure is usually in the camera circuit; Second, the viewfinder image normal and the TV show bad image, in which case AC adapter or failure is usually caused by poor line connection; third is the TV image viewfinder image normal and bad reasons for this failure is usually caused by a viewfinder
The Image Color is Not Natural. If the tape monitor records the image normal and five color or color negative, in general, failure occurred in the video section: On the contrary, if the tape recording monitor image is not normal and normal, was caused by AC adapter or a bad connection. If both are negative, the fault in the camera circuit
Image Blur, Focus is Not Good. If the manual focus well and auto-focus poor, often malfunction in the automatic focusing circuit. If the manual and automatic focus are bad, the fault component, mainly in the lens focus
No Audio Playback Images. In such cases, it can be taken with a tape recorder into the common normal replay, monitor sound effects. If the sound normal, the fault in the AC adapter; the other hand, failure in the audio and microphone recording microphone circuit or circuits
The Machine Does Not Work. After booting the keys had no role in the viewfinder no light, the box body does not work. Such power failures are usually caused by abnormal or power circuits. Should first check the battery voltage or AC AC adapter output voltage is normal, if normal then the fault in the power circuit
Tape Handling Failure. Viewfinder and monitor can be displayed the image when shooting, but the tape is not loaded into or take it out. Such failure generally occurs in the movement and its drive circuit
Maintenance:
Avoid highlight, high or cold temperature, water, shock, collision, corrosion, smoke, dust, magnetic, X-ray etc
Only when it is in great need, a little bit of dust will not affect the image quality. When you need cleaning, it shall use a soft brush, such as the sable brush or hair dryer to remove dust. If you want to wipe the lens, you should use the pump to blow away the dust, wipe it with lens paper
You can use a transparent display protection sticker to protect the screen
