A solid state image sensor including a light receiving section having a number of light receiving cells arranged in matrix, and a reading and storing section having a first set of switching and memory transistors for reading bright signals read out of light receiving cells arranged in a row and storing the same for a horizontal scanning period, a second set of switching and memory transistors for reading dark signals out of light receiving cells arranged in a row and storing the same for a horizontal scanning period, and a set of reading transistors for reading the bright and dark signals simultaneously out of the first and second sets of memory transistors for respective pixels successively. The light receiving section and the reading and storing section are formed integrally in the same semiconductor substrate. In order to remove the fixed pattern noise, there is derived differences between the simultaneously readout bright and dark signals with the aid of a differential amplifier.

An image pickup device electronically senses an object to be photographed and generates an electronic still image signal. An A/D converter converts the electronic still image signal generated by the image pickup device into a digital signal. An error correction coding section performs error correction coding for the digital signal obtained by the A/D converter. A recording modulation section performs recording modulation of an output from the error correction coding section so as to perform predetermined magnetic recording. A recording section records an output from the recording modulation section on a predetermined magnetic recording medium. Different recording media can be used, such as magnetic and semiconductor, provided on respective imaging sub-systems. A semiconductor imaging sub-system is provided with an I/O controller for establishing compatibility with signals of the magnetic imaging sub-system.

A color imaging apparatus includes means for electronically non-linearly expanding or compressing the dynamic range of an image signal output therefrom. Separate output signals of respective brightness for different colors are logarithmically compressed, inverse-logarithmically converted, then linear-matrix-converted and multipled by a compression factor of brightness level for the respective color signals to produce a logarithmically compressed color signal without varying the tone.

The present invention relates to a cosmetic composition for keratin fibers, such as a composition for coloring hair or a composition for reshaping hair, comprising: (a) at least one phosphoric surfactant; (b) at least one non-ionic surfactant, (c) at least one polyol; (d) at least one oil; and (e) at least one alkaline agent. It is preferable that the cosmetic composition further comprises at least one higher alcohol. The present invention is useful because it does not generate odor while maintaining a level of cosmetic performance as comparable to that of conventional cosmetic compositions.

This invention provides equipment for fabricating partitioning ribs of a plasma display device. The equipment comprises a head, a driver, an X position sensor and a Y position sensor, a laser displacement sensor for detecting the distance of the head from a glass plate or substrate, a motor and a motor driver for moving the head relative to the glass plate, and a CPU for controlling various circuits. The head has nozzle members for ejecting partitioning rib grains by an electrostatic ejection method or ink jet technology to form partitioning ribs. The driver controls the volume of the partitioning rib grains ejected from the head. The X and Y position sensors detect the position of the head relative to the glass plate within a plane.

An image data coding apparatus includes a preprocessing unit for executing preprocessing including compression for input image data in units of screens to generate a preprocessed output. A quantizing unit quantizes the preprocessed output with a predetermined quantization width to generate a quantized output. A variable-length coding unit executes variable-length coding for the quantized output. A target-amount-of-codes output unit outputs information concerning a target amount of codes corresponding to one screen. A quantization width predicting unit predicts a suitable quantization width on the basis of the information from the variable-length coding unit to supply information concerning the predicted quantization width to the quantizing unit. The quantizing unit quantizes the preprocessed output generated by the preprocessing unit with the predicted quantization width included in the information from the quantization width predicting unit.

摘要:
An electronic still camera comprising an image-pickup section, and A/D conversion section, a primary recording section, a secondary recording section, a control section, and an image-signal processing section. The image-pickup section generates still-image signals. The A/D conversion section converts the still-image signals into digital signals. The primary recording section records the digital signals. The control section reads the digital signals recorded by the primary recording section, at least during non-operating period of the image-pickup section. The image-signal processing section performs predetermined processing on the digital signals read by the control section, thereby outputting data. The predetermined processing includes at least data compression. The secondary recording section records the data output by the image-signal processing section.
