摘要： To prevent effectively the flickering of an image due to the switching of a polarization direction while reducing speckle noise. A polarization switching unit is provided in an optical path of laser light to a projection surface A and periodically switches a polarization direction of the laser light emitted therefrom between p and S polarization. A laser control unit controls laser light sources in synchronization with the switching by the polarization switching unit and determines a driving current corresponding to a grayscale to be displayed on the basis of driving current characteristics for P polarization when the polarization direction of the laser light is the P polarization. In addition, the laser control unit determines the driving current corresponding to the grayscale to be displayed on the basis of the driving current characteristics for P polarization when the polarization direction of the laser light is the S polarization.

摘要： Techniques capable of effectively reducing local speckle noise caused by scanning with laser light involving a variation in scanning speed and improving the overall quality of an image are provided. In some examples, a laser light source emits laser light with an output level corresponding to a display grayscale of a pixel according to a predetermined waveform pattern within a pixel display period which is set to increase as a scanning speed is reduced. The waveform pattern is set such that a unique relaxation oscillation of the laser light source increases as the scanning speed is reduced. A scanning mirror reflects the laser light emitted from the laser light source in a predetermined scanning order according to its deflection angle so as to be projected onto a projection surface.

摘要： An optical pickup device includes a liquid crystal element having transparent electrodes, one of which has a plurality of areas divided in a concentric manner. The liquid crystal element can compensate for a spherical aberration that is generated when information is reproduced or recorded on two types of optical recording media. When one of two light beams supporting the two types of optical recording media having a larger value of an effective diameter is a first light beam and the other having a smaller value is a second light beam, parts of areas located inside an effective diameter of the second light beam and areas located outside the same to which the same voltage is applied for compensating for a spherical aberration generated in the first light beam are connected electrically to be the same potential.
