    摘要: A projector includes a light source unit that supplies light, and a spatial light modulator that modulates light supplied from the light source unit according to an image signal. The spatial light modulator is driven by an applied voltage whose polarity is reversed according to a polarity-reversing frequency which is specific to the spatial light modulator. The light source unit supplies light which is modulated according to pulse width modulation for which fundamental frequency is set based on the polarity-reversing frequency.

    摘要: An image display method of splitting a frame into a plurality of sub frames by multiplying a frame frequency of an incoming image signal by an integer, and dividing an image that is originally for the frame into pieces for display on the sub frames. In the image display method, the luminance component included in the image is given a priority for display on a first sub frame that is at least one of the sub frames, and a color-difference component included in the image is given a priority for display on a second sub frame that is also one of the sub frames but not the first sub frame.

    摘要: An image recording method for an image recording medium is used in an image display apparatus that changes an image on a light valve and changes quantity of light which is incident on the light valve via a light control element according to an input image signal. The image recording method includes accommodating a range of brightness information which an object to be imaged indicates, in an entire range of brightness information which an image recording apparatus can record in the image recording medium; and recording a light-control control signal for controlling the light control element when an image signal is recorded on the image recording medium. The light control element is generated on the basis of the range of the brightness information uniformly expanded, in synchronization with the image signal.

    摘要: An array of memory cells is physically divided into a data area and a tag area so that respective parts of the two areas share a word line but can be separately erased en bloc. The data area and tag area sharing one word line constitute a single logical unit. In the logical unit, the tag area stores location information for defective memory cells in the corresponding data area. On the basis of this information, the system avoids the use of the defective memory cells. The defective memory cell information is programmed in a test step performed after chip manufacture and, at the same time, ECCs are generated for the defective memory cell information and written to the tag area. Furthermore, the system is informed of the validity of the data area that shares a word line with a tag area by writing predetermined data to the tag area. Even when the data area is erased en bloc, the tag area is not erased and the defective memory cell information is retained there.

    摘要: A nonvolatile memory with cluster-erase flash capability. A cluster information sector is included in each of N clusters, the cluster information sector of each cluster being written with the sequence number assigned to the cluster so that no two clusters have the same sequence number. When erasing a given sector, a controller saves its sequence number prior to erasure. Then, when initializing a given erased sector, the controller sets its sequence number to a value greater than the current maximum sequence number. The controller writes user data to sectors other than the cluster information sector for the cluster thus initialized according to their address sequence. Accordingly, an invalid sector can be distinguished from a valid sector without using an overwrite approach.
