摘要： A calculation device may include a data read unit configured to sequentially read pixel values in the first direction while sequentially making a shift in the second direction from a position of a reference pixel in the first and second directions, a first data integration unit configured to output a sum of values of pixels as a first integration value, a second data integration unit configured to output a sum of values of pixels as a second integration value, and a data cumulative calculation unit configured to obtain a cumulative value by accumulating pixel values respectively included in a first rectangular data area expressed by the first number of pixels in the first direction and the second number of pixels in the second direction based on the first integration value output from the first data integration unit and the second integration value output from the second data integration unit.

摘要： A focal point detection device includes: a rate conversion section which converts a transmission rate of an image signal, which is associated with a subject image imaged via an imaging lens on a part of a receiving surface of an imaging device, such that the image signal input to the rate conversion section at a first transmission rate is output from the rate conversion section at a second transmission rate that is slower than the first transmission rate; a filter which extracts a frequency component from the image signal output at the second transmission rate from the rate conversion section; and an evaluation value calculation section which calculates an evaluation value of a focus state of the imaging lens, based on a signal of the frequency component that is extracted by the filter.
