• lines_per_second indicates the maximum number of exposure lines in one second. For example, if the maximum exposure time of a frame is 1125 lines and the frame rate is 30 fps, then lines_per_second = 1125 x 30. Generally, the value of this parameter is also two times lines_per500ms of hi_isp_exp_info.
• Note that the time of a line must be the same as that of the readout timing of a line. Generally, the time of the exposure lines of a sensor is the same as that of one readout line. However, the time of each readout line of some sensors is the time of two exposure lines. In this case, you need to divide the line count by 2 to obtain the actual value of lines_per_second. The rule applies.
