A split unit capable of providing a stereoscopic image having less laterality is provided. The split unit includes: a beam splitter which transmits first imaging light as a part of light incident on an incident surface of the beam splitter, and reflects second imaging light as another part of the light incident on the incident surface; and a reflecting member which reflects the second imaging light reflected by the beam splitter. At least one of a reflectance of the reflecting member and a beam splitting characteristic of the beam splitter is set based on the following formulae:/(1+)=1&#x2212;

Afforded is an optical element holder allowing high-accuracy stereo images to be taken. The holder includes: a rectangular parallelepiped beam splitter () having a rectangular incident surface (); a pair of mutually opposing holding members () into which end portions of the beam splitter along the x-axis are fitted; and a base portion () and screws () that press on the holding members (), drawing them toward each other. Each of the holding members () has a flat surface portion covering a lateral surface of the beam splitter (), and a peripheral wall portion standing along the periphery of the flat surface potion. A width, along the x-axis, whereby the peripheral wall portion and a first light-exit surface opposing the incident surface () of the beam splitter () overlap is greater than a width, in the same orientation, whereby the incident surface () and the peripheral wall portion overlap.

An encoding device includes: a difference generation unit for obtaining a first pixel difference value as a difference value between a first pixel value and a pixel value of a pixel having the same color as the first pixel positioned in the vicinity of the first pixel; a quantization width decision unit for deciding a quantization width in data generation by quantizing the first and the second pixel value according to the number of digits of an unsigned integer binary value of the first pixel difference value and the number of digits of an unsigned integer binary value of the second pixel difference value generated in the difference generation unit for the second pixel value of the second pixel; a quantization width information generation unit for generating quantization width information having a quantization width used for quantization/decoding of the first and the second pixel value; and a quantization unit for generating a first and a second compressed encoded pixel value of n-bit length.

Digital signal encoding and decoding device and method

An image encoding method is for obtaining, from a pixel data string containing pixel values of a plurality of pixels in a pixel array where the pixels are arrayed, a pixel data string containing a quantized representative value into which at least one of the pixel values is encoded. Encoding is performed by allocating a specific quantized representative value when a pixel value of a pixel is a specific pixel value, and by allocating a quantized representative value other than the specific quantized representative value when the pixel value is other than the specific pixel value.

A device is provided for taking high resolution still pictures while recording video without pausing video recording. Plural channels are provided for reaching pixel values from a CMOS sensor, and the output of each channel is input to a corresponding A/D conversion circuit. The channels are configured so that the pixels that are added together are read simultaneously. The data added by the pixel value adder is used as the video data for video recording. When a still picture is captured during video recording, the pixel data is stored in memory with capacity to store one frame, and is sequentially output from the image sensor as the still picture data.

Imaging data processing device, imaging data processing method, and imaging element

The resolution, frame rate, or both can be improved when imaging moving subjects in an imaging apparatus using a CMOS image sensor. The imaging apparatus has an image sensor having a two-dimensional array of pixels. Each of the pixels includes an element operable to produce an electric charge by photoelectrically converting light from an imaged subject and a part operable to accumulate the produced charge and output an accumulated charge or a signal representing the accumulated charge. The imaging apparatus also has an area control unit operable to define a specified area of the image sensor containing a plurality of pixels and an area density control unit operable to specify a density of pixels read from the specified area defined by the area control unit.

When a method or apparatus of assuring simultaneous exposure, such as a mechanical shutter, is not provided with a MOS imaging sensor, moving subjects are distorted with a MOS image sensor when capturing a still image of a fast-moving subject because imaging and reading are not simultaneous across the MOS sensor. Changing the MOS sensor exposure sequence and reading sequence, and interpolating the read data, change and correct the read sequence line by line when imaging a high resolution moving image, and thus improve distortion in moving subjects.
