发明名称 Light emitting device, image processing device, and electronic apparatus
摘要 A light emitting device includes a plurality of light emitting elements, a first storage unit that stores first correction values corresponding to the light emitting elements, a counting unit that counts the number of pixels whose gray-scale values designated by image data are within a predetermined range included in an image, a selection unit that selects a first mode or a second mode according to the relationship between the number counted by the counting unit and a threshold value, and a driving unit that drives the light emitting elements corresponding to the predetermined number of pixels to emit amounts of light corresponding to the first correction values when the first mode is selected by the selection unit, and drives the light emitting elements corresponding to the predetermined number of pixels to emit amounts of light corresponding to the image data when the second mode is selected by the selection unit.
