RM-42 Camera Module Troubleshooting Nokia Customer Care Introduction to camera module troubleshooting Background, tools and terminology Faults or complaints in camera operation can be roughly categorised into three subgroups: 1 Camera is not functional at all; no image can be taken. 2 Images can be taken but there is nothing recognizable in them. 3 Images can be taken and they are recognizable but for some reason the quality of images is seriously degraded, or customer complains about image quality..
PAGE 426
RM-42 Camera Module Troubleshooting Nokia Customer Care Sharpness Good quality images are 'sharp' or 'crisp', meaning that image details are well visible in the picture. However, certain issues, such as non-idealities in optics, cause image blurring, making objects in picture to appear 'soft'. Each camera type typically has its own level of performance.
PAGE 427
RM-42 Camera Module Troubleshooting Nokia Customer Care The amount of light available In dim conditions camera runs out of sensitivity. The exposure time is long (especially in the night mode) and the risk of getting shaken (= blurred) images increases. In addition, image noise level grows. The maximum exposure time in the night mode is ¼ seconds. Therefore, images need to be taken with extreme care and by supporting the phone when the amount of light reflected from the target is low.
PAGE 428
Nokia Customer Care RM-42 Camera Module Troubleshooting Figure 75 Near objects get skewed when taking images from a moving vehicle Temperature High temperatures inside the mobile phone cause more noise to appear in images. For example, in +70 degrees (Celsius), the noise level may be very high, and it further grows if the conditions are dim.
PAGE 429
RM-42 Camera Module Troubleshooting Nokia Customer Care Figure 76 Noisy image taken in +70 degrees Celsius Phone display If the display contrast is set too dark, the image quality degrades: the images may be very dark depending on the setting. If the display contrast is set too bright, image contrast appears bad and "faint". This problem is solved by setting the display contrast correctly. This is normal behaviour; do not change the camera module.
PAGE 430
RM-42 Camera Module Troubleshooting Nokia Customer Care Figure 77 Image taken against light Flicker In some occasions a bright fluorescent light may cause flicker in the viewfinder and captured image. This phenomenon may also be a result, if images are taken indoors under the mismatch of 50/60 Hz electricity network frequency. The electricity frequency used is automatically detected by the camera module.
PAGE 431
RM-42 Camera Module Troubleshooting Nokia Customer Care Figure 78 Flicker in an image; object illuminated by strong fluorescent light Bright light outside of image view Especially the sun can cause clearly visible lens glare phenomenon and poor contrast in images. This happens because of undesired reflections inside the camera optics. Generally this kind of reflections are common in all optical systems. This is normal behaviour; do not change the camera module.

RM-42 Camera Module Troubleshooting Nokia Customer Care Figure 81 Good image taken outdoors Image quality analysis Possible faults in image quality When checking for possible errors in camera functionality, knowing what error is suspected significantly helps the testing by narrowing down the amount of test cases.
PAGE 435
RM-42 Camera Module Troubleshooting Nokia Customer Care When taking a white image, use uniformly lightened white paper or white wall. One possibility is to use uniform light but in this case make sure that the camera image is not flickering when taking the test image. In case flickering happens, try to reduce illumination level. Use JPEG image format for analysing, and set the image quality parameter to ‘High Quality’. Black spots in an image are caused by dirt particles trapped inside the optical system.
PAGE 436
RM-42 Camera Module Troubleshooting Nokia Customer Care If dust particles are found on the sensor, this is classified as a manufacturing error of the module and the camera should be replaced. Any particles inside the cavity between the protection window and lens have most probably been trapped there in the assembly phase at a Nokia factory. Unauthorized disassembling of the product can also be the root of the problem.
PAGE 437
RM-42 Camera Module Troubleshooting Nokia Customer Care If there appears to be a clearly noticeable difference between the reference image and the test images, the module might have a faulty lens. In this case, the module should be changed. Always recheck the resolution after changing the camera module. If a different module produces the same result, the fault is probably in the camera window. Check the window by looking carefully through it when replacing the module.

Nokia Customer Care RM-42 Camera Module Troubleshooting Figure 84 Image taken with greasy protection window Bright point light sources might cause images that have flares around the light source if the protection window is dirty. A smeared fingerprint may be hard to see on the protective window but if will affect the image quality. These flares can be avoided by cleaning the window with a suitable cloth.

Nokia Customer Care RM-42 Camera Module Troubleshooting Figure 86 Image of point light sources taken with a dirty (finger print) protective window Image bit errors Bit errors are image defects caused by data transmission errors between the camera module and the phone baseband and/or errors inside the camera module. Usually bit errors can be easily detected in images, and they are best visible in full resolution images. A good practice is to use a uniform white test target when analysing these errors.
PAGE 441
RM-42 Camera Module Troubleshooting Nokia Customer Care Figure 87 Bit errors caused by JPEG compression One type of bit error is a lack of bit depth. In this case, the image is almost totally black under normal conditions, and only senses something in very highly illuminated environments. Typically this is a contact problem between the camera module and the phone main PWB. You should check the camera assembly and connector contacts.
PAGE 442
RM-42 Camera Module Troubleshooting Nokia Customer Care Hot pixels are pixels that easily saturate in dim light conditions. It is normal to get a lot of noise and hot pixels in night conditions or otherwise dark conditions. The hot pixels should disappear when the ambient light is increased, but may still appear in darker areas of an otherwise well illuminated scene. When examining an image for defect pixels test images should be viewed as 100% enlargements on a PC monitor.

RM-42 System Module Nokia Customer Care Figure 97 MMC interface The basic multimedia card concept is based on the following communication signals CLK, CMD and DAT. With each cycle of the CLK signal one bit transfer on the DAT and CMD line is done. The maximum CLK frequency is 20MHz (specified in multimedia card specification). Maximum used CLK frequency at the time is 16MHz. CMD is a bi-directional command channel used for card initialization and data transfer commands.

RM-42 System Module Nokia Customer Care WCDMA receiver functionality In the WCDMA mode, the received signal is fed from the antenna to a duplex filter. After the duplex filter the signal goes via a balun to an LNA (Low Noise Amplifier) residing in N7500. From the LNA, the signal goes trough a band pass filter. After filtering, the signal goes to the down conversion mixer, which converts the signal to baseband I and Q signals. At the BB frequency the signal is amplified, and fed to a low pass filter.
PAGE 499
RM-42 System Module Nokia Customer Care Another function of the detector voltage is to steer the DC/DC converter, which is providing a variable supply voltage for the WCDMA PA. WCDMA PA module The WCDMA PA is housed in a separate module having: • a variable supply voltage input for the amplifier stages (Vcc11), • a battery supply voltage for the bias circuits (Vcc12), • and two bias current inputs. Bias currents are generated by 5-bit DA converters in the RF ASIC.

The error amplifier resides in N7501, and it controls the transmitter power of GSM. Detector output from the PA gives a DC level proportional to the output power. The DC voltage is fed to the negative input of the error amplifier, where it is compared to the level of the reference signal, TXC. TXC is got from the BB circuitry.
