Abstract: A probabilistic signal point shaping device comprises circuitry configured to map data blocks of input bits of an input bit stream onto mapping symbols, wherein said mapping symbols are distributed according to a predetermined probability distribution and represented by complex-valued signal points or non-uniformly spaced amplitude levels, assign bit labels to said mapping symbols, determine redundancy bits from the bits of said bit labels, transform said redundancy bits into a redundancy rule, and apply the redundancy rule to the mapping symbols to obtain output symbols.

Abstract: A physical quality detecting device includes: a detecting unit that detects a physical quantity supplied from the outside with photo-converting pixels which are two-dimensionally arranged, each of which has a selecting transistor for outputting a signal from the detecting unit to a signal line. In the physical quality detecting device, the selecting transistor is a depletion-type transistor. The signal line is selectively coupled to a reference voltage.

Abstract: Disclosed herein is a display apparatus, including: a pixel array section including a plurality of pixel circuits disposed in a matrix and each including a driving transistor for producing driving current, a storage capacitor for storing information of a image signal amplitude, an electro-optical element connected to an output terminal side of the driving transistor, and a sampling transistor for writing information of the signal amplitude into the storage capacitor, the driving transistor being operable to produce driving current based on the information stored in the storage capacitor and supply the driving current to the electro-optical element to cause the electro-optical element to emit light; a driving signal fixing circuit for keeping the driving current fixed; and a light blocking layer provided on the light input side of a transistor which participates in the driving signal fixing function and for preventing appearance of leak current of the transistors arising from light irradiation.
