摘要： An image sensing system includes an image sensor, a sensing controller, an additional unit, and a sensing parameter calculator. The image sensor includes a plurality of unit pixels and configured to generate raw image data indicative an image of an object from pixel signals from the plurality of unit pixels. The sensing controller is configured to control, based on a sensing parameter, a sensing condition of the image sensor for each set of the unit pixels. The parameter addition circuit is configured to obtain a parameter added data by adding the sensing parameter and the raw image data. The sensing parameter calculator is configured to calculate a distribution of pixel values for each set of the unit pixels, calculate an updated sensing parameter based on the distribution of pixel values, and transmit the updated sensing parameter to the sensing controller and the parameter addition circuit.

摘要： An imaging device includes an image sensing device and an image signal processor. The imaging sensing device includes a pixel array of sensing pixels comprising a first pixel for sensing incident light and having a first dynamic range and a second pixel for sensing incident light and having a second dynamic range, the pixel array of sensing pixels structured to have a ratio of a number of the first pixels to all sensing pixels to be higher than a ratio of a number of second pixels to all sensing pixels. The image signal processor is configured to receive and process pixel data from the image sensing device to generate a high dynamic range (HDR) image corresponding to a larger dynamic range than the first dynamic range or the second dynamic range, based on pixel data of the first pixels and pixel data of the second pixels in the pixel array.

摘要： An image processing device is disclosed. The image processing device includes at least one first pixel having a first sensitivity, a second pixel having a second sensitivity different from the first sensitivity, a processor, and a synthesizer. The processor calculates a sampling position of the at least one first pixel and a sampling position of the second pixel, determines a reference position and adjusts the sampling position of the at least one first pixel or the second pixel based on the reference position.
