摘要： In a projection type display apparatus that projects an image by inputting a light beam emitted from a light source to a spatial light modulation device, it is intended to provide a lens array as a component of an illumination optical system that is low in manufacturing cost, provides high screen illuminance, and enables miniaturization of the projection type display apparatus. The dimension of the cell lenses of a second lens array is not uniform in one of the row direction and the column direction. Since the cell lenses are rectangular when viewed from the front side, the second lens array can be manufactured with a metal mold having a simple shape. The boundary lines between the cell lenses are straight and level differences at the boundary lines are small, sink marks of the second lens array are small, and the efficiency of utilization of light beams is high. Further, since the dimension of the cell lenses is not uniform in the other of the row direction and the column direction, the corresponding dimension of the second lens array can be reduced.
摘要翻译：在通过将从光源发射的光束输入到空间光调制装置来投影图像的投影型显示装置中，旨在提供作为制造成本低的照明光学系统的部件的透镜阵列，提供高屏幕照度，并且能够实现投影型显示装置的小型化。第二透镜阵列的单元透镜的尺寸在行方向和列方向之一上不均匀。由于当从前侧观察时，单元透镜是矩形的，所以可以用简单形状的金属模制造第二透镜阵列。单元透镜之间的边界线是直的，边界线处的电平差小，第二透镜阵列的凹痕小，并且光束的利用效率高。此外，由于单元透镜的尺寸在行方向和列方向上的另一个上不均匀，所以可以减小第二透镜阵列的相应尺寸。

摘要： An image-taking apparatus is disclosed which allows a selection of a type of image stabilization to be used from optical image stabilization and electronic image stabilization as required to provide an excellent output image. The image-taking apparatus has an image generator which is operable in a first mode in which it performs electronic image stabilization processing based on a plurality of images sequentially taken with an image-pickup device to generate an output image and a second mode in which it generates an output image without performing the electronic image stabilization processing on an image taken with the image-pickup device. The image-taking apparatus also has a controller which causes image stabilization operation to be performed through driving of an optical system in both of the first and second modes and selects one of the first mode and the second mode.
