The Bayer pattern color filter defines a first 2×2 subset of pixels sensitive to red light; a second 2×2 subset of pixels sensitive to green light; a third 2×2 subset of pixels sensitive to green light; and a fourth 2×2 subset of pixels sensitive to blue light. A set of 1×1 on-chip lenses (OCLs) includes a different 1×1 OCL disposed over each pixel in the second 2×2 subset of pixels and the third 2×2 subset of pixels. A set of 2×1 OCLs or 2×2 OCLs includes a 2×1 OCL or a 2×2 OCL disposed over each pixel in the first 2×2 subset of pixels and the fourth 2×2 subset of pixels.

Abstract: The invention relates to an image sensing device and an image sensing method thereof. The image sensing device includes: an image sensing array and an image processing circuit. The image sensing array generates multiple pixel data, and the pixel data includes a first pixel data and a second pixel data. The first pixel data is generated by exposing for a first exposure time, the second pixel data is generated by exposing for a second exposure time, and the first exposure time is shorter than the second exposure time. The image processing circuit executes an automatic exposure convergence operation with the first pixel data to generate new exposure parameters for the automatic exposure convergence operation. The second exposure time is adjusted according to the new exposure parameters, so that the second pixel data is pixel data with changed exposure time.

Abstract: The present technology relates to a solid-state imaging device, an imaging apparatus, and an electronic apparatus, which can suppress a color mixture without lowering the sensitivity.
In pixels (red pixels (R pixels), green pixels (G pixels), and blue pixels (B pixels)) other than W pixels and adjacent to the W pixels, light shielding films thicker than those of the W pixels are formed at positions adjacent to the W pixels. Furthermore, the shorter the wavelength, the thicker the light shielding film in the RGB pixels other than the W pixels. The present technology is applicable to the solid-state imaging device.

Abstract: Techniques are described for efficient high-resolution output of an image captured using a high-pixel-count image sensor based on pixel binning followed by luminance-guided umsampling. For example, an image sensor array is configured according to a red-green-blue-luminance (RGBL) CFA pattern, such that at least 50-percent of the imaging pixels of the array are luminance (L) pixels. Pixel binning is used during readout of the array to concurrently generate a downsampled RGB capture frame and a downsampled L capture frame. Following the readout, the L capture frame is upsampled (e.g., by upscaling and interpolation) to generate an L guide frame with 100-percent luminance density. An upsampled RGB frame can then be generated by interpolating the RGB capture frame based both on known neighboring RGB information (e.g., from the RGB capture frame and previously interpolated information), as adjusted based on local luminance information from the L guide frame.
