RM-135 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.
PAGE 198
RM-135 Camera Module Troubleshooting Nokia Customer Care Sensitivity Camera module's sensitivity to light. In equivalent illumination conditions, a less sensitive camera needs a longer exposure time to gather enough light in forming a good image. Analogous to ISO speed in photographic film. Sharpness Good quality images are 'sharp' or 'crisp', meaning that image details are well visible in the picture.
PAGE 199
RM-135 Camera Module Troubleshooting Nokia Customer Care Figure 66 Sharpness of picture is worse in edges than in center Figure 67 Especially this type of images are affected much by lack of sharpness in edges / corners Geometrical distortion Camera lens will cause some amount of so called barrel distortion in images. In practice, this appears as bending of straight objects in edges of the image. See the two figures below for an example. This is normal behavior, do not change the camera module.
PAGE 200
RM-135 Camera Module Troubleshooting Nokia Customer Care Figure 68 Geometrical distortion Amount of light available In dim conditions camera runs out of sensitivity. Exposure time is long (especially in night mode) and the risk of getting shaken (= blurred) images grows. Image noise level grows. The maximum exposure time in night mode is ¼ seconds, so 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 201
RM-135 Camera Module Troubleshooting Nokia Customer Care Figure 70 Near objects in image get skewed when shooting from a moving car Temperature High temperatures inside the mobile phone will cause more noise to appear in images, e.g. in +70 degrees of celsius the noise level may be very high, and it further grows if the conditions are dim. This is also normal to camera operation. This is normal behavior, do not change the camera module.

Flicker In some occasions a bright fluorescent light may cause flicker to be seen in the viewfinder and captured image. This phenomena may also result if pictures are taken indoors under mismatch of 50/60 Hz electricity network frequency. The frequency will be detected from operator country sign information.

RM-135 Camera Module Troubleshooting Nokia Customer Care Camera construction This section describes the mechanical construction of both camera modules for getting a better understanding of the actual mechanical structure of each module.
PAGE 205
RM-135 Camera Module Troubleshooting Nokia Customer Care The camera module uses socket type connecting. For versioning, laser marked serial numbering is used on the PWB. The main parts of the module are: • Lens unit including lens aperture. • Infrared filter; used to prevent infrared light from contaminating the image colors. The IR filter is glued to the EMI shielded camera body. • Camera body; made of conductive metallized plastic and attached to the PWB with glue.
PAGE 206
RM-135 Camera Module Troubleshooting Nokia Customer Care When taking a white image, use uniformly lightened white paper or white wall. Another option 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 occurs, try to reduce the illumination level. Use JPEG image format for analysing, and set the image quality parameter to ‘High Quality’.

RM-135 Camera Module Troubleshooting Nokia Customer Care 2 The photographed object is too close – the camera lens operates with distances from 40 cm to infinity. This is no cause to replace camera module. 3 User has tried to take pictures in too dark conditions, and images are blurred due to handshake or movement. This is no cause to replace camera module. 4 There is dirt between the protection window and camera lens. 5 The protection window is defective.
PAGE 208
Nokia Customer Care RM-135 Camera Module Troubleshooting 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 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. The errors are clearly visible, colourful sharp dots or lines in camera images.

RM-135 Camera Module Troubleshooting Nokia Customer Care Flash LED troubleshooting Introduction to flash LED troubleshooting A fault or complaint associated to LED flash operation can be roughly categorized into two subgroups: 1 Flash is not functional at all (no light output at all). 2 Images can be taken and they are recognizable but for some reason the quality of images is degraded. Examples of quality degradations: • Brightness is not sufficient. • Brightness is too much = overexposed.
PAGE 216
RM-135 Camera Module Troubleshooting Nokia Customer Care Distance to the target (too close) There is no feedback in the flash system, which means that the light output is constant in every situation. This causes the images to overexposure, when shot from close distance. The flash LED is designed to work optimally between distances of 70 cm – 1.2 m. This is normal behaviour; do not change the flash module.
PAGE 217
RM-135 Camera Module Troubleshooting Nokia Customer Care Figure 86 Dark and noisy image Shaken (= blurred) images The traditional xenon flash has the advantage of stopping the movement. This is a result of an extremely short and intense light pulse, which makes it possible for a camera to use very short exposure time. Due to the weak output of the LED flash, the exposure time has to be actually increased in the viewfinder mode in total blackness, instead of shortening it.
PAGE 218
RM-135 Camera Module Troubleshooting Nokia Customer Care Figure 87 Shaken image Camera white balance failure and overexposure due to presence of ambient light Because the spectral output of the flash is known, the white balance and the exposure control of the camera work in optimal way with the flash in total blackness. This is why some of the pictures may fail (i.e.
PAGE 219
RM-135 Camera Module Troubleshooting Nokia Customer Care Figure 88 Camera white balance failure and overexposure Colour difference between different modules There is some variation in the spectrum of the flash, which derives from the manufacturing process of the white LEDs. Because of this variation, there may be some variation in the colour of the images as well. This is normal behaviour; do not change the flash module.

RM-135 Camera Module Troubleshooting Nokia Customer Care Steps 1. Take an image with the flash and monitor at same time whether the LED module flashes. Results If the LED flashes normally, the overall functionality of the module is OK. Testing image colours with flash Context With the help of this test you can check if the image colours are normal when using the flash. Steps 1. Take an image of a target, which contains something white in total blackness from less than 1 m range.

RM-135 System Module and User Interface Nokia Customer Care Introduction Phone description RAPIDO is the main digital baseband ASIC in the phone. It contains functionality for both WCDMA and GSM EDGE. AVILMA is mainly the audio ASIC in the phone and BETTY is basically the energy management controller for the phone. Bluetooth and FM radio are physically integrated in one single ASIC.
PAGE 234
RM-135 System Module and User Interface Nokia Customer Care Energy management Battery and charging BL-4B battery The phone is powered by a BL-4B battery block. It provides a capacity of 700 mAh minimum and contains a BSI resistor for the battery identification. Its battery interface is based on blade type connector where the transceiver side has blades and the counter parts are on battery side.
PAGE 235
RM-135 System Module and User Interface Nokia Customer Care Figure 94 Small (left) and wide (right) charger plugs Charging is controlled by energy management, and external components are needed to protect the baseband module against EMC, reverse polarity and transient frequency deviation. Backup battery When the main battery is not attached EM ASIC (N2200) goes in backup mode using back-up battery that supplies voltage to RTC in EM ASIC (N2200).
PAGE 236
RM-135 System Module and User Interface Nokia Customer Care Power key and system power-up When the battery is placed in the phone the power key circuits are energized. When the power key is pressed, the system boots up (if an adequate battery voltage is present). Power down can be initiated by pressing the power key again (the system is powered down with the aid of SW). The power key is connected to EM ASIC N2200 (AVILMA) via PWRONX signal.
PAGE 238
RM-135 System Module and User Interface Nokia Customer Care Clocking scheme In BB5, two main clocks are provided to the system: 38.4MHz RF clock produced by VCTCXO in RF section and 32.768kHz sleep clock produced by AVILMA with an external crystal. 32 k Sleep Clock is always powered on after startup. Sleep clock is used by RAPIDO for low-power operation. SMPS Clk is 2.4 MHz clock line from RAPIDO to BETTY. In deep sleep mode, when VCTCXO is off, this signal is set to '0'-state. BT Clk is 38.

RM-135 System Module and User Interface Nokia Customer Care USB USB (Universal Serial Bus) provides a wired connectivity between a PC and peripheral devices. It is a differential serial bus. USB 2.0 is supported with full speed (12 Mbps). Hot swap is supported, which means that USB devices may be plugged in/out at any time. This phone is provided with a specific connector for mini USB. CBUS interface CBUS is a "main" system control bus in BB5.
PAGE 241
RM-135 System Module and User Interface Nokia Customer Care Figure 97 SIM interface The EM ASIC handles the detection of the SIM card. The detection method is based in the BSI line. Because of the location of the SIM card, removing the battery causes a quick power down of the SIM IF. The EM ASIC SIM1 interface supports both 1.8 V and 3.0 V SIM cards. The SIM interface voltage is first 1.8 V when the SIM card is inserted, and if the card does not response to the ATR a 3 V interface voltage is used.
