A lens array wheelreceives light irradiated in a direction parallel to its rotation axis, to cyclically deflect the light. On each of liquid crystal display panelsR,G, andB, the light is circularly scrolled, the effect of substantial intermittent illumination is produced, and hold blurring is reduced. A panel driverstarts to feed a pixel-driving signal in the succeeding frame to a pixel existing at a position, through which an illuminating area passes, on each of the liquid crystal display panelsR,G, andB.

Projection type video display unit and illuminating device

A hold-type display apparatus is more likely to suffer the deterioration in the visibility of moving images due to the blur effect, compared to an impulse-type display apparatus. A single frame period is divided into a first period and a second period. Pixel data to be written to a pixel are written in a concentrated manner in the first period during a frame period. At this time, a write value for the pixel is set to twice a value of the image data in order not to lower the brightness of the images as a whole. However, only if the doubled value exceeds a range that can be displayed, the remaining pixel data are written in the second period. Thus, the change in display brightness approximates the impulse-type display apparatus, so that the visibility of moving images is improved.

Display method, display apparatus and data write circuit utilized therefor

In a projection type video display apparatus comprising means for circularly scrolling and irradiating irradiated light in a direction perpendicular to the line direction on a hold-type display panel, a projection type video display apparatus comprises means for varying overdrive in conformity with the timing of irradiation of the irradiated light.

A motion image recording apparatus inputs an image code train coded according to intra-frame coding or inter-frame coding in order to easily perform data retrieving in fast-forward reproduction of motion image data recorded according to prediction coding. A header detection circuit (,) detects a header of a specific frame from an input code train. A recording control circuit (,) outputs data related to a record unit of a recording medium (,). A redundant bit insert control circuit (,) inserts a redundant bit into the input code train such that the detected header is located at the leading end of the record unit.
