Abstract: This invention discloses an optical lens for image pickup, in order from an object-side to an image-side including a first lens, a second lens, a third lens and fourth lens. The first lens has positive refractive power. The second lens has negative refractive power. The third lens has positive refractive power. The fourth lens has negative refractive power with at least one inflection point on image-side surface. Wherein, each of the lenses has at least one aspheric surface. The optical lens for image pickup further includes an aperture stop and an image sensor. The aperture stop is disposed between the object and the second lens, and the image sensor is disposed at the image-plane. The optical lens for image pickup also satisfies with specific conditions.

Abstract: The invention is an optical lens assembly for capturing images and an image capture device therewith. The optical lens assembly for capturing images includes, along an optical axis, a total reflection prism, a first lens group having negative focal power, wherein the first lens group comprises a lens having negative focal power, a second lens group having positive focal power, wherein the second lens group comprises at least one lens having an aspherical optical surface, a third lens group having positive focal power, wherein the third lens group comprises at least one lens having positive focal power and at least one lens having negative focal power, and a fourth lens group having positive focal power, wherein the fourth lens group comprises at least one lens having an aspherical optical surface. Thereby, the aberration can be improved and a thin lens module for capturing images can be achieved.

Abstract: This invention discloses an optical zoom lens assembly, sequentially arranged from an object side to an image side along an optical axis comprising: a first lens-group, a second lens-group and a third lens-group. The first lens-group with negative refractive power comprises at least one positive lens, and at least one negative lens. The second lens-group with positive refractive power comprises at least one positive lens, and at least one negative lens. The third lens-group with a positive refractive power comprises at least one aspheric lens. Therein, refractive indexes of the first lens-group, the second lens-group and the third lens-group are small than 1.69. Therefore, the present invention can reduce manufacturing costs and provide good image quality to be applied to cameras, cell phone cameras and other devices.

Abstract: The present invention discloses a vision detection device and a vision detection method of the vision detection device provided for a camera to detect a long-range view. The vision detection device comprises a casing, a template, a mirror group and a light-emitting module. The casing comprises a light exit hole. The template is transparent and has a pattern formed on a surface of the template. The mirror group comprises at least three non-planar mirrors. The light-emitting module projects a light beam through the template, and the light beam is then reflected through the mirror group and emitted in form of parallel light to the light exit hole.

Abstract: An image capturing apparatus and an electronic apparatus are described. The image capturing apparatus comprises a body, a flash lamp, a lens and a fill lamp. The flash lamp is disposed on the body and emits a flash light, and the lens is also disposed on the body. The lens collects and provides lights to an image sensing unit disposed inside the body to generate images. The fill lamp is disposed on the lens and electronically connects to the body. The fill lamp further locates on the direction of the flash lamp facing the lens, and thus provides lights as a filled light when the lens shields the light emitted by the flash lamp.
