35 / 69 page PYTHON 480 www.onsemi.com 35 Mode Changes and Frame Blanking Dynamically reconfiguring the sensor may lead to corrupted or non-uniformilly exposed frames. For some reconfigurations, the sensor automatically blanks out the image data during one frame. Frame blanking is summarized in the following table for the sensor’s image related modes. NOTE: Major mode switching (i.e. switching between master, triggered or slave mode) must be performed while the sequencer is disabled (reg_seq_enable = 0x0). Table 26. DYNAMIC SENSOR RECONFIGURATION AND FRAME BLANKING Configuration Corrupted Frame Blanked Out Frame Notes Shutter Mode and Operation triggered_mode Do not reconfigure while the sensor is acquiring images. Disable image acquisition by setting reg_seq_enable = 0x0. slave_mode Do not reconfigure while the sensor is acquiring images. Disable image acquisition by setting reg_seq_enable = 0x0. subsampling Enabling: No Disabling: Yes Configurable Configurable with blank_subsampling_ss register. Frame Timing black_lines No No Exposure Control mult_timer No No Latency is 1 frame fr_length No No Latency is 1 frame exposure No No Latency is 1 frame Gain mux_gainsw No No Latency configurable by means of gain_lat_comp register afe_gain No No Latency configurable by means of gain_lat_comp register. db_gain No No Latency configurable by means of gain_lat_comp register. Window/ROI roi_active See Note No Windows containing lines previously not read out may lead to corrupted frames. roi*_configuration* See Note No Reconfiguring the windows by means of roi*_configuration* may lead to corrupted frames when configured close to frame boundaries. It is recommended to (re)configure an inactive window and switch the roi_active register. See Notes on roi_active. Black Calibration black_samples No No If configured within range of configured black lines auto_blackal_enable See Note No Manual correction factors become instantly active when auto_blackcal_enable is deasserted during operation. blackcal_offset See Note No Manual blackcal_offset updates are instantly active. CRC Calculation crc_seed No No Impacts the transmitted CRC Sync Channel bl_0 No No Impacts the Sync channel information, not the Data channels. img_0 No No Impacts the Sync channel information, not the Data channels. crc_0 No No Impacts the Sync channel information, not the Data channels. tr_0 No No Impacts the Sync channel information, not the Data channels. |
