    • An electro-optical device which has a program period, a light-emitting period, an erasing period, and a lights-off period in one frame and controls the light-emitting period according to a light emission gray-scale level including a driving transistor that includes a current control terminal, a current input terminal, and a current output terminal, and controls a current amplifying ratio on the basis of a voltage between the current control terminal and the current input terminal, an electro-optical element that is supplied with the driving current from the driving transistor to emit light, a storage capacitor that stores the charge corresponding to the voltage between the current control terminal and the current input terminal of the driving transistor, a constant current source that outputs a constant current that is independent of the light emission gray-scale level, a voltage source that outputs a driving stop signal that turns off the driving transistor, a selection transistor that opens/closes a current path connecting any one of the constant current source and the voltage source with the driving transistor, and a scan line that outputs open/close signals that turn on/off the selection transistor. The program period is a period when the selection transistor is turned on by outputting an open signal to the scan line, and when the constant current flows from the constant current source to the driving transistor through the current path, the charge corresponding to the voltage between the current control terminal and the current input terminal is stored in the storage capacitor. The light-emitting period is a period when the selection transistor is turned off by outputting a close signal to the scan line, and the voltage corresponding to the charge stored in the storage capacitor is supplied between the current control terminal and the current input terminal of the driving transistor to supply the driving current to the electro-optical element. The erasing period is a period when the selection transistor is turned on by outputting the open signal to the scan line, and the driving stop signal is supplied to the driving transistor from the voltage source through the current path to turn off the driving transistor so that the electro-optical element stops emitting light. The lights-off period is a period when the selection transistor is turned off by outputting the close signal to the scan line, and the electro-optical element retains a non-light-emitting state. A time constant of the scan line is set so that signal delay of the open/close signals is 10% or less of a theoretical value.

    • An electro-optical device includes a pixel that has an electro-optical element with a light transmittance that changes to a predetermined value in response to an applied voltage, which changes in response to the temperature. A light source irradiates light to the pixel. A driving unit includes a predetermined number of sub-fields having the same length in one frame. The driving unit provides either an on-voltage indicating light-on or an off-voltage indicating light-off to the pixel in each of the predetermined number of the sub-fields in response to the grayscale to be displayed. A temperature measuring unit measures the temperature and outputs a temperature signal. A time controlling unit controls the length of one sub-field on the basis of the temperature signal. A light intensity controlling unit controls the intensity of the light incident on the pixel on the basis of the temperature signal.

    • A data recording device for recording video data and/or audio data on a recording medium comprises a compression-encoding unit for compressing and encoding an inputted data stream, hierarchizing a variable data block, and blocking a plurality of generated lower-level data blocks as an upper-level data block, a data block temporary storage unit for temporality storing at least one upper-level data block generated in the compression-encoding unit and including n number (n is a given natural number) of lower-level data blocks; and a control unit for managing a size of the upper-level data block generated in the compression-encoding unit and controlling the compression-encoding unit to perform blocking of data blocks in such a way that the upper-level data block includes a plurality of lower-level data blocks to an extent that a size of the upper-level data block does not exceed a capacity of the data block temporary storage unit, wherein, upon receiving a generation completion signal indicating completion of generating a lower-level data block from the compression-encoding unit, if a total size of a plurality of lower-level data blocks counted from a beginning of a currently generated upper-level data block in the compression-encoding unit is equal to or larger than a difference between the capacity of the data block temporary storage unit and a size of a maximum lower-level data block of the plurality of the lower-level data blocks, the control unit makes an end process request for performing an end process to determine the lower-level data block which has just been generated as a last lower-level data block to be included in the currently generated upper-level data block, to the compression-encoding unit.
