摘要： The present disclosure relates to a drive control device, a drive control method, an information processing system, and an information processing method for an information processing system capable of suppressing the occurrence of banding that occurs in a direct view light emitting diode (LED) display during re-imaging.
In order to make luminance of the LEDs lower, lower-order bits used for control using thinned light emission are fixed at 0 to disable the control using thinned light emission, and light emission is controlled for each plurality of LEDs set as a unit using pseudo gradation for gradation control by controlling the number of LEDs that emit light and the positions of the LEDs that emit light. The present disclosure is applicable to a passive-matrix driven LED display device.

摘要： Selection of an evaluation index based upon statistical values of respective evaluation indices is disclosed. In one example, an information processing apparatus comprises an evaluation index unit that determines a plurality of evaluation indices on a basis of imaging data obtained by imaging a subject, wherein the evaluation indices are respectively based upon different wavelength component combinations of the imaging data. An evaluation value unit determines an evaluation value based on a statistical value of each of the evaluation indices, for each of the evaluation indices. A selection unit then determines a selected evaluation index from the evaluation indices on a basis of the evaluation values.
