Document Number: 001-05325 Rev. ** Page 7 of 20 Autobrite ® The ACM100 module includes both automatic and manua l control of both the integration period and the dyna mic range. The automatic control may be based on the entire contents of the image, or on a user specified region of interes t. The following sections describe the control in more detail. Region of Interest The camera includes a region of interest feature th at can be used to influence the automatic control of the dyna mic range and the integration period. The user designates a r egion of interest (of programmable size and position) within the full frame. The camera automatically optimizes the exposure and dynamic range for this region (alternatively, the region can be ignored for exposure and dynamic range setting). The region is defined by specifying the upper left and lower right corners of a rectangle using pixel row and column numbers. Tint Control The camera provides for both automatic and manual control of the integration period (exposure time). This can be specified independently of the gamma control – that is either can be fixed or set automatically. The Tint control algorithm attempts to set the camera to an integration period that pla ces the average pixel value at a default or user specified level. In addition to setting the desired image average, the user may bound the integration period that is available to the automatic control. This can prevent the integration from exce eding motion blur limits in dark environments. Gamma Control The camera provides for both automatic and manual control of the dynamic range by selecting one of 29 response, or gamma, curves. This can be specified independently of the Tint control – that is either can be fixed or set a utomatically. Autobrite tracks two parameters to control the sele ction of a gamma code: the number of saturated pixels (those a t the maximum digital value) and the number of pixels in the top histogram bin of the image. These parameters are tracked on a per image basis using binary counters. The algorithm can be tuned by setting the number of bits active in each counter. The logic responds to the overflow of the counter. Therefore the maximum number of saturated pixels and minimum number of top bin pixels desired are both set as a power of two. The algorithm works by increasing the dynamic range when the number of saturated pixels (max gray level) exc eeds the saturation setting. The dynamic range is reduced wh en the number of pixels in the top bin of a histogram (of programmable size) falls below the specified value. In addition to setting the target values, the user may limit the maximum gamma setting available to the algorithm. This may be useful to applications that respond poorly to extremely high gamma values. Transition Control The camera includes features that allow the user to influence the response of the camera to dynamic lighting cond itions. Human vision applications may desire a slow, smooth response to changes in lighting for aesthetic reasons. Machine vision application, not being influenced by aesthetic concerns, may desire a faster response. The camera includes f eatures to allow the user to adjust the dynamic response of the camera to suit the application. Image Processing Fetaures The camera includes a number of features that impro ve or remove artifacts from the image. These features are described in the following sections. Dark Current Removal The camera automatically senses the dark current us ing inactive, or dark, columns in the sensor. The curre nt is measured for each row and subtracted from the image . This feature may be disabled by the user. Column Fixed Pattern Noise Correction During the vertical retrace period of scanning the imager, a fixed voltage is applied to all of the columns of the imager. This voltage is sampled by the ADC and used to calculate offset errors on a column basis. These errors are then removed from the next frame. This feature may be disabled by the user. Defective Pixel Correction The camera includes a feature to compensate for def ective pixels. A 3x3 non-linear filter is used to screen o ut defective pixels. The center pixel is compared against the average of its neighbors and if it is too high or low, the average is substituted for the defective pixel. This feature may be disabl ed by the user. Sharpening Filter The camera includes a 3X3 sharpening filter. The us er may disable or specify the strength of the filter. Detailed Specifications The following sections outline some of the detailed specifications of the module.

The bits are defined as follows: Bit Definition 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 0 1 0 0 0 0 1 0 0 0 0 0 1 1 0 0 AB_K TINT_EN TINT [15:13] AB_K : This bit field can be used to slow down the respons e of the automatic Tint control to changes in the scene. This may be desirable if smooth changes betw een camera settings are preferable to rapid response. New Tint values are calculated based on t he assumption that the image average will scale linearly with the Tint setting. The algorithm works by calculating the difference between the current and target image average and then based on that differe nce calculating what change in Tint is required to attain the desired image average. The algorithm the n multiplies the change in Tint by the AB_K value and then adds the result to the current Tint value. Therefore, smaller values of AB_K will cause the Tint value to adjust in smaller increments, although the size of the steps will remain proportional to the lighting change for a fixed AB_K. The following table shows some examples of how AB_K affects the Tint calculations for a desired image average of 128.

When enabled, the TINT value specified in this register will be used and automatic control of the integration period is disabled. Writing a ‘0’ to this location will disable manual control and enable the automatic control of the integration period. Changes to this bit will take affect on the next full frame of video. [11:0] TINT: This field specifies the integration period as a nu mber of rows. The maximum integration is 525 rows. At a frame rate of 30 fps, writing a value of 0X20D would result in a 33 msec integration period. Changes to this parameter will take affect on the next full frame of video.

The bits are defined as follows: 0x03 Merge Bins Control 1 The Merge Bins Control register is used to enable and control the behavior of the merge bins contrast enhancement algorithm. The merge bins algorithm can be controlled by specifying a Q function that indicates how strongly gray levels should be affected by the algorithm. The Q function can be specified in one of two methods. The first method assumes that a maximum Q is specified for gray level zero and that this value is reduced for increasing gray levels at a specified slope until a minimum Q value is reached. The alternative is to manually load a table which will specify a unique Q value for each gray level.

This field is set to a 2 frames by default to accommodate the one frame latency between calculation of a new Tint value and its taking effect. Note that the Tint will settle in the same number and size of steps, but will take longer to settle. To change the size of steps that Tint will use to adjust, use the AB_K parameter. [11:0] MIN_TINT: This field is used to specify the minimum integration period that the Autobrite algorithm will use to control the camera. It is only valid when manual control of the integration period is disabled. It is specifie d as the number of row periods you wish to have the sensor integrate. The maximum integration is 525 rows.

The bits are defined as follows: 0x05 Merge Bins Control 2 The Merge Bins Control register is used to enable and control the behavior of the merge bins contrast enhancement algorithm. The merge bins algorithm can be controlled by specifying a Q function that indicates how strongly gray levels should be affected by the algorithm. The Q function can be specified in one of several methods as shown in Figure 13 . [11:0] Max_Q: The Max Q field specifies the Q value for gray level zero. This forms the starting point for the Q function. Note: if the Min_Q value is set to be higher than t he Max_Q value, the result will be a flat threshold at the Min_Q value.

[14:11]GAMMA_SKIP: This field specifies the frequency at which gamma may be updated by the automatic control algorithm (when enabled.) The default is set to 2 to account for a one frame latency between the calculation of a new value and its effect. Lower values may res ult in an overshoot in the response to a step change in image lighting. [10:6]MAX_GAMMA: These bits define the maximum gamma code that will be available to the algorithm controlling the dynamic range of the sensor. Changes to this parameter will take affect on the next full frame of video. [5:1] GAMMA: These bits specify the value of gamma to be used when user gamma is enabled. Increasing values of gamma represent increasing amounts of signal com pression – resulting in increased dynamic range. Values of 3 and below are linear and the max imum value of 31 represents the maximum dynamic range of the sensor. Changes to this field take affect immediately – even in the middle of a frame. This may result in a frame with the top and bottom portions of the image being taken with different gamma settings. [0] GAMMA_EN: Writing a ‘1’ to this bit will enable the use of the gamma value specified in the GAMMA field of this register to be used in place of the value calculate d by the Autobrite algorithm.

It is incremented each time the artwork is changed on the PCB in the camera. [11:8] HW_Ver: This field reads back the hardware version of the camera. It starts at zero with each PCB version and is incremented as changes are made to the hardware that do not affect the PCB artwork. [7:4] RTL_Maj_Ver: This field reads back the major revision code for t he firmware in the FPGA. This field is independent of the PCB and HW versions and is incre mented each time a major change to the functionality of the FPGA is implemented. [3:0] RTL_Min_Ver: This field is reset each time the RTL_Maj_Ver field changes and is incremented each time the firmware is changed. Write [15:1] Reserved: These bits are reserved for future use and should not be set. Write ‘0’s to this field. [0] RST: Writing a ‘1’ to this bit will return all registers to the power on state.
