摘要： 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.

摘要： 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.

摘要： A MOS image sensor and an imaging apparatus using this image sensor enable controlling sensor driving with a high degree of freedom using a simple control circuit design and minimal wiring lines. The light reception unit of the image sensor in this imaging apparatus is segmented into a plurality of areas and conventional shift registers are constructed in multiple layers, thus enabling controlling the multiple sensor areas by means of a relatively simple circuit design. The imaging apparatus can thus locally change exposure and imaging conditions in parts of a single frame. Problems due to underexposure and overexposure are thus suppressed, and images with a wide dynamic range can be captured.

摘要： 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.

摘要： 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.

Each of the holding members (8) has a flat surface portion covering a lateral surface of the beam splitter (5), 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 (12) of the beam splitter (5) overlap is greater than a width, in the same orientation, whereby the incident surface (12) and the peripheral wall portion overlap.
