Abstract: An apparatus is described having an image signal processor. The image signal processor has a plurality of depth calculation units to calculate a respective time of flight depth value for different pixel array locations. Each of the plurality of depth calculation units is to receive a response signal from a same pixel in a pixel array so that the plurality of depth calculation units are able to calculate multiple depth values for the different locations of the pixel array from respective response signals from different groups of pixels in the pixel array of which the pixel is a member. Each of the groups include pixels of different receive clock phases sufficient to calculate a respective depth value. Another apparatus is also described where multiple depth values are similarly calculated from different groups of pixels that each include a same pixel but where a depth calculation unit calculates each of the multiple depth values.

Abstract translation: 描述了具有图像信号处理器的装置。 图像信号处理器具有多个深度计算单元，以计算不同像素阵列位置的飞行深度值的相应时间。 多个深度计算单元中的每一个用于从像素阵列中的相同像素接收响应信号，使得多个深度计算单元能够从像素阵列的各个响应信号中计算出不同位置的多个深度值 像素为其成员的像素阵列中的不同像素组。 每个组包括足以计算相应深度值的不同接收时钟相位的像素。 还描述了另一种装置，其中从包括相同像素的不同像素组类似地计算多个深度值，但是深度计算单元计算多个深度值中的每一个。

Abstract: A method of determining a modulation transfer function (MTF) for an image includes receiving an image captured through the optical system, performing edge detection on columns or rows in the image to calculate a plurality of edge points, calculating a plurality polynomials to fit to the calculated edge points, each of the plurality of polynomials varying in degree, selecting a polynomial from the plurality of polynomials to represent the detected edge, and estimating the MTF based on the selected polynomial.
