* For non-decode IS4813 and IS4815 engines, depth of field data is for reference only. Actual values may vary
depending on environmental conditions, host hardware, and decoding software.
Depth of field data was measured at 25°C under typical indoor lighting. Performance may vary depending on
testing conditions.
