Problems solved by technology

[0005] It is impossible to simply add more functions of a digital still camera to the camera module, because doing so will sacrifice the main function of the digital device attached to the module

Embodiment Construction

[0023] FIG. 1 shows a prior art digital device 2 installed in a prior art digital camera module 1 . The digital camera module 1 includes an input interface 20 and an output data interface 18 connected to the host device 2 . The input interface 20 is connected to supply an output signal to the CMOS image sensor 3 . The CMOS image sensor receives light that has passed through the optical lens system 60 and the optical filter 64 and then reaches the image sensor 3 . The image sensor 3 provides output signals to the imaging hardware acceleration device 19 , and the imaging hardware acceleration device 19 provides image data to the host device 2 through the output data interface 18 .

[0024] The imaging hardware acceleration device is a hard-wired signal processing device with a pipeline structure. Data is processed sequentially, one level after another. It is fast, low power, and small in size. The imaging hardware acceleration device includes a preprocessing unit 15 and an i...

Abstract

A camera module chip-set comprising: a decompressor configured to decompress image data received from a host device connected to the camera module chip-set; and a processor, different to the decompressor, configured to control transmission of the decompressed image data to the connected host device, in order for the decompressed image data to be displayed on a display of the host device.

Description

technical field [0001] Embodiments of the present invention relate to a digital camera module and a digital host device. Background technique [0002] Until recently, if a user of a digital device (eg, computer, mobile phone, PDA, etc.) wanted to take digital photography, that user had to use a separate, dedicated digital still camera (DSC). [0003] However, users do not expect to purchase and carry two separate dedicated digital devices. To solve this problem, digital devices having integrated cameras have been developed, and camera modules attached to the digital devices have been developed. [0004] However, the image quality and camera functionality provided by integrated cameras and camera modules is far inferior to that provided by dedicated digital still cameras. For example, with current camera modules for mobile phones, the resolution is up to 350,000 pixels, while digital still cameras are now achievable with resolutions greater than 4 megapixels. [0005] It i...
