Image processing apparatus, display system, electronic apparatus, and method of processing image
An image processing apparatus which corrects pixel data corresponding to pixels configuring a display image of a display device having light emitting elements includes an information storage unit which, in units of one or a plurality of pixels of the display device, stores information corresponding to operating currents of light emitting elements included in the one or plurality of pixels, and a pixel data correction unit which corrects the pixel data based on the information corresponding to the operating currents stored in the information storage unit.
1. An image processing apparatus which corrects pixel data corresponding to pixels configuring a display image of a display device having light emitting elements, comprising:
an information storage unit which, in units of one or a plurality of pixels of the display device, stores information corresponding to operating currents of light emitting elements included in the one or plurality of pixels;
a pixel data correction unit which corrects the pixel data based on the information corresponding to the operating currents stored in the information storage unit, wherein a correction information is generated while the information corresponding to the operating current is stored in the information storage unit;
a correction information generating unit which generates correction information corresponding to the operating currents of the light emitting elements included in the one or plurality of pixels, wherein
the information storage unit stores the correction information, and
the correction information generating unit generates the correction information based on difference information having a minimum operating current of the operating currents of the light emitting elements included in the one or plurality of pixels as a reference in one screen;
a condition setting register in which control data corresponding to a pixel data correction range are set; and
a pixel data analysis unit which, based on the control data set in the condition setting register, carries out a process of determining whether or not to correct the pixel data, wherein
the pixel data correction unit is such that an enable control of a process of correcting the pixel data is carried out based on a result of the processing of the pixel data analysis unit,
the condition setting register including an R component condition setting register, a G component condition setting register and a B component condition setting register,
the enable control including R component enable control, G component enable control and B component enable control,
the R component enable control is based on the control data set in the R component condition setting register,
the G component enable control is based on the control data set in the G component condition setting register, and
the B component enable control is based on the control data set in the B component condition setting register.
2. The image processing apparatus according to claim 1 , wherein the control data specifying that each component pixel value of R, G and B is equal to or larger than each of a pixel value corresponding to a set gradation value.
