Benefits of technology

[0008] It is therefore an object of the invention to provide an image capturing apparatus and an image capturing method thereof. When the image capturing apparatus is still in a preview mode, the apparatus compresses a preview image in advance and judges an image complexity according to at least one of a set of factors consisting of a compressed setting, a resolution of the preview image and a size of the compressed preview image. Thus, after entering a capturing mode, the image capturing appa

Problems solved by technology

However, the conventional image capturing apparatus cannot compress the to-be-captured image data until it enters the capturing mode.
Thus, the

Embodiment Construction

[0022]FIG. 3 is a block diagram showing an image capturing apparatus 20 according to a preferred embodiment of the invention. Referring to FIG. 3, the image capturing apparatus 20, such as a digital camera, includes an image sensing unit 210, an image processing unit 220, an image storing unit 230, an image compressing unit 240 and a control unit 250.

[0023]FIG. 4 is a schematic illustration showing the image capturing apparatus in a preview mode. Referring to FIG. 4, the image capturing apparatus 20 has two operation modes, one of which is a preview mode and the other of which is a capturing mode.

[0024] When the image capturing apparatus 20 is in the preview mode, the image sensing unit 210 captures a preview image S6 and outputs a preview image signal S7 according to the preview image S6. The image processing unit 220 processes the preview image signal S7 to output preview image data S8 by way of, for example, demosaicking, gamma correction, color reproduction and edge enhancemen...

Abstract

An image capturing apparatus and an image capturing method. The apparatus captures and compresses a preview image, and judges an image complexity and determines a preview compressed setting value according to at least one of a set of factors consisting of a compressed setting, a resolution of the preview image and a size of a compressed preview image. Next, the apparatus captures a to-be-captured image, and determines an initial compressed setting value according to at least one of a set of factors consisting of the image complexity, and the resolution of the to-be-captured image and a compressed image target size, which is a new compressed initial value. Then, the apparatus compresses the image according to the initial compressed setting value to obtain a compressed image approaching a predetermined size or speed up a converging speed of an image compressing loop.

Description

[0001] This application claims the benefit of Taiwan application Ser. No. 95117009, filed May 12, 2006, the subject matter of which is incorporated herein by reference. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The invention relates in general to an image capturing apparatus and a method thereof, and more particularly to an image capturing apparatus for compressing a preview image in a preview mode to judge an image complexity and calculate a preview compressed setting value in advance, and an image capturing method. [0004] 2. Description of the Related Art [0005]FIG. 1 is a schematic illustration showing a first conventional image capturing apparatus 10 in a capturing mode. Referring to FIG. 1, the conventional image capturing apparatus 10 includes an image sensing unit 110, an image processing unit 120, an image storing unit 130, an image compressing unit 140 and a control unit 150. When the conventional image capturing apparatus 10 enters a capturing mod...
