RM-437; RM-449; RM-450 Camera Module Troubleshooting 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.
RM-437; RM-449; RM-450 Camera Module Troubleshooting 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.
RM-437; RM-449; RM-450 Camera Module Troubleshooting Figure 27 Blurring caused by shaking hands Movement in bright light If an image is taken of moving objects or if the device is used in a moving vehicle, object 'skewing' or 'tilting' may occur. This phenomenon is fundamental to most CMOS camera types, and usually cannot be avoided. The movement of camera or object sometimes cause blurring indoors or in dim lighting conditions because of long exposure time.
RM-437; RM-449; RM-450 Camera Module Troubleshooting 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. If the phone processor has been heavily loaded for a long time before taking an image, the phone might have considerably higher temperature inside than in the surrounding environment.
RM-437; RM-449; RM-450 Camera Module Troubleshooting 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. In some very few countries, both 50 and 60 Hz networks are present and thus probability for the phenomenon increases.

RM-437; RM-449; RM-450 Camera Module Troubleshooting The camera module as a component is not a repairable part, meaning that the components inside the module may not be changed. Cleaning dust from the front face is allowed only. Use clean compressed air. 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.
RM-437; RM-449; RM-450 Camera Module Troubleshooting Figure 37 Effects of dust on optical path If large dust particles get trapped on top of the lens surface in the cavity between camera window and lens, they will cause image blurring and poor contrast. The dust gasket between the window and lens should prevent any particles from getting into the cavity after the manufacturing phase. Dust in this position should be blown away by using compressed air.
RM-437; RM-449; RM-450 Camera Module Troubleshooting 5 The protection window is defective. This can be either a manufacturing failure or caused by the user. The window should be changed. 6 The camera lens is misfocused because of a manufacturing error. 7 Very high level of digital zoom is used A quantitative analysis of sharpness is very difficult to conduct in any other environment than optics laboratory. Therefore, subjective analysis should be used.
RM-437; RM-449; RM-450 Camera Module Troubleshooting 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. See the following figure. Figure 40 Bit errors caused by JPEG compression One type of bit error is a lack of bit depth.

RM-437; RM-449; RM-450 Camera Module Troubleshooting 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.
RM-437; RM-449; RM-450 Camera Module Troubleshooting 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.
RM-437; RM-449; RM-450 Camera Module Troubleshooting Figure 43 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.
RM-437; RM-449; RM-450 Camera Module Troubleshooting Figure 44 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.

RM-437; RM-449; RM-450 System Module and User Interface Energy management Battery and charging BP-4L battery The phone is powered by a 3-pole BP-4L battery S-pack 1500 mAh battery. The three poles are named VBAT, BSI and GND where the BSI line is used to recognize the battery capacity. This is done by means of an internal battery pull down resistor. Figure 47 Battery pin order The battery temperature is estimated by measuring separate battery temperature NTC via the BTEMP line.
RM-437; RM-449; RM-450 System Module and User Interface 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).
RM-437; RM-449; RM-450 System Module and User Interface Mode Description PWR_OFF In this mode (warm), the main battery is present and its voltage is over N2300 BETTY master reset threshold. All regulators are disabled, PurX is on low state, the RTC is on and the oscillator is on. PWR_OFF (cold) mode is almost the same as PWR_OFF (warm), but the RTC and the oscillator are off. RESET RESET mode is a synonym for start-up sequence. RESET mode uses 32 kHz clock to count the REST mode delay (typically 16ms).

RAPIDO controls the functionality of EM ASIC (N2200) and EM ASIC (N2300) ASICs with CBUS. CBUS is a four-wire half-duplex master-slave interface. In BB5 CBUS clock frequency is 2.4 MHz.
RM-437; RM-449; RM-450 System Module and User 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.

RM-437; RM-449; RM-450 System Module and User Interface RF description Block diagram The RF block diagram for RM-437 uses RF ASIC N7505 that performs the RF back-end functions of receive and transmit function of the cellular transceiver. Receiver (RX) An analogue signal is received by the phone's antenna. The signal is converted to a digital signal and is then transferred further to the baseband (eg. to the earpiece). The receiver functions are implemented in the RF ASIC.
RM-437; RM-449; RM-450 System Module and User Interface Transmitter (TX) The digital baseband signal (eg. from the microphone) is converted to an analogue signal, which is then amplified and transmitted from the antenna. The frequency of this signal can be tuned to match the bandwidth of the system in use (eg. GSM900). The transmitter functions are implemented in the RF ASIC. Even though the GSM and WCDMA signals pass different components, the principles of the transmission is the same.
